Index

Zombie:Reloaded a alternative to Zombie Mod with a lot of new features and improvements. It's open source and made for Counter-Strike: Source and runs on a powerful scripting platform called SourceMod.

The objectives is to change the game into humans versus zombies. Humans try to survive by camping, barricading and hiding. Zombies try to zombify humans by using their knife.

At a random time after the round starts, one or more random humans are turned into zombies. Zombies have certain advantages as running faster and more health points. Humans have huge amounts of ammo (or unlimited), and their bullets knock back zombies. A lot more attributes can be adjusted for both zombies and humans in different classes.

For best results the server should have Counter-Strike: Source maps made for Zombie Mod.

Concept

Zombie: Reloaded requires that the following stuff is installed on the server:

Extract the content of the zip file into "cstrike" on the server. The folder and file structure is already set up correctly and ready to be extracted into "cstrike".

The plugin should work with default configuration. Start the server and join a team. Once the round starts there sould be some messages at the chat with "[ZR]". Or type "!zmenu" in the chat to bring up the zombie menu to confirm that the plugin is running.

When upgrading there might be changes to configuration files. They must either be reconfigured or merged with old settings.

Reloading Zombie:Reloaded with SourceMod is not recommended. Changing the map works in most cases, but some console variables might not be updated. Do a server restart for a complete refresh of console variables.

In this manual commands or paths may be written in a certain style that tells how to use it.

Note that the style itself is not written, but it's used as an indicator to tell if a parameter is optional or not.

Example syntax of a command:

zr_class_modify <classname|"zombies"|"humans"|"admins"> <attribute> <value> [is_multiplier]

Some paths may look like:

cfg/sourcemod/zombiereloaded/<mapname>.cfg

How to read syntaxes like this is explained below.

Optional parameters is not required and usually have a default value or action. They are marked with brackets.

Example:

zr_somecommand [number]

Usage examples:

zr_somecommand
zr_somecommand 10

Required parameters must be specified for the command to function. Usually if no parameters are written the command replies with some info about the syntax.

Less than (<) and greather than (>) symbols marks required parameters.

Examples:

zr_somecommand <number>
zr_infect <target>

Usage examples:

zr_somecommand 100
zr_infect "unnamed"

Some commands have parameters that support multiple pre defined options. Usually it's specifying a name, a index or a predefined value. Each option is separated by a "|" symbol. Only one of the options listed is used in a command.

Example:

zr_do_something <index|name|"all">

Usage examples:

zr_do_something 1
zr_do_something "all"
zr_do_something "unnamed"

Since parameters are separated by spaces, text (strings) should be quoted. It's a good habit to do this on all string parameters to avoid parsing mistakes.

Example:

zr_infect "unnamed" "player"
zr_do_something "example text. test."

Example of bad usage:

zr_do_something example text. test.

The last example actually have 3 parameters while it should be only one. This may cause unexpected results and is an example of why strings should be quoted.

These are the default configuration files. The paths are relative to the "cstrike" folder.

Default Configuration Files

Type:	File:
Main conf.	cfg/sourcemod/zombiereloaded/zombiereloaded.cfg
Map config.	cfg/sourcemod/zombiereloaded/<mapname>.cfg
Post map conf.	cfg/sourcemod/zombiereloaded/<mapname>.post.cfg
Hitgroup conf.	addons/sourcemod/configs/zr/hitgroups.txt
Class conf.	addons/sourcemod/configs/zr/playerclasses.txt
Weapon conf.	addons/sourcemod/configs/zr/weapons.txt
Download list	addons/sourcemod/configs/zr/downloads.txt
Model list	addons/sourcemod/configs/zr/models.txt

The post map configuration file is executed after all features of ZR is done loading. Commands that modify loaded data must be put in post configuration files. How to configure each file is explained in their own sections.

Configuration files also can be reloaded in-game when testing or tuning stuff.

Configuration File Console Commands

Syntax:
zr_config_reload <file alias>
Reloads a config file. Parameters: file alias The module to reload. Available options: models downloads classes weapons hitgroups
zr_config_reloadall
Reloads all config files.

The log system used in Zombie:Reloaded is pretty powerful and customizable. It's based on logging flags and a module filter.

Log Flags

Flag:	Bit No.:	Value:	Description:
LOG_CORE_EVENTS	1	1	Log events from the plugin core like config validation and other messages.
LOG_GAME_EVENTS	2	2	Log admin commands, console commands, and game related events from modules like, suicide attempts and weapon restrictions.
LOG_PLAYER_COMMANDS	3	4	Log events that are triggered by players, like chat triggers, teleporting and class changes.
LOG_DEBUG	4	8	Log debug messages, if any. Usually only developers need to enable this log flag.
LOG_DEBUG_DETAIL	5	16	Log additional debug messages with more details. May cause spam depending on module filter settings. Usually only developers need to enable this log flag.

To combine several logging flags use the sum of their values. A combination could be "3", which is these log flags:

LOG_CORE_EVENTS + LOG_GAME_EVENTS
1 + 2

Most server setups donesn't need different flag settings. Default is fine.

To decode the value you must convert it from decimals to binary, and count from right to left what bits that are 1. Look up the bit number (not value) in the table above.

As an example on using the number 11 it's 1011 in binary. Counting from right we see that the following bit numbers are on: 1, 2, and 4. That is the flags:

LOG_CORE_EVENTS + LOG_GAME_EVENTS + LOG_DEBUG
1 + 2 + 8

Most operating systems or distributions have a calculator that can convert between binary and decimal numbers with scientific mode enabled. An online unit converter like below can also be used.

Configuration files for each map is supported. They're executed after the main configuration files are executed, and are ideal for customizing map settings. These files are just regular configuration files and can also have standard console commands like setting map time. Map configuration files are optional.

The main purpose of these files is to make it possible to change settings for Zombie:Reloaded on certain maps. That could be scaling knockback, restricting certain weapons, changing class attributes or changing ambience sound.

Other map configuration plugins should also work if certain features that doesn't exist in Zombie:Reloaded map configurations is needed.

There are two kinds of map configs; pre and post. Pre map configuration files are executed before the modules and data is loaded. They're useful for changing configuration sets for certain modules like classes. Post map configuration files are executed after the modules are loaded. Certain stuff have to be placed in this one to be effective, like changing class attributes.

Map Configuration File Types

Type:	Executed:	Path:
Pre	Before modules and data loading	cfg/sourcemod/zombiereloaded/<mapname>.cfg
Post	After modules	cfg/sourcemod/zombiereloaded/<mapname>.post.cfg

If not explicit specified in the module documentation, use pre configuration.

The model configuration file is a list of models used on the server stored in Valve's key/value format.

The models listed in this file are also precached when the server starts. Custom models used, but not listed in this file will cause a "model not precached" error on the server, so they must be listed in this file.

In addition models can be restricted to certain groups using the "access" attribute.

List of available model attributes:

Model Attributes

Attribute:	Value type:
name	text
File name of model file, without extension.
path	text
Path to model files. Must end with "/". Windows servers can use "\" in paths, but they also work with "/". The path is relative to "cstrike".
team	text
What team the model belongs to. Options: zombies Zombie players. Includes mother zombies. humans Human players.
access	text
Access mode of the model. Options: public Everyone can use the model. Included in public random selections. admins Model can only be used by admins. Included in public random selections but only applied to admins. hidden Model is excluded from public random selections. motherzombies Model can only be used by mother zombies. group Use group authentication. See "group" attribute.
group	text
Name of SourceMod group to use for model authentication if access is "group". If access is anything else than "group" this setting is ignored and can be blank (""). Only players that is a member of this group can use this model. Root admins can't use this model if they're not a member.

For example usages see examples in default model configuration.

Put the list of models in:

addons/sourcemod/configs/zr/models.txt

Custom materials and overlays must be listed in the download list so clients will download them. Use one line per file, with paths relative to the "cstrike" folder.

List files to be downloaded in the following file:

addons/sourcemod/configs/zr/downloads.txt

Look at the default downloads in that file for an example on how to list files to be downloaded.

Note: The ambiecne sound file doesn't need to be listed.

The class system makes it possible to have different zombies and humans with customized skills. It cannot be turned off, but class selection menus can be disabled. If there is only one class in each team, the class selections menus are automatically disabled.

The class configurations are stored in Valve's key/value format, and the file that's loaded should be specified in the "zr_config_path_playerclasses" console variable. It's possible to change this variable with per-map configuration files to have different sets of classes on one or more maps.

Default path is:

configs/zr/playerclasses.txt

Note: The path is relative to the "sourcemod" folder.

The file contains a short description of all attributes. Details are explained below.

There are three class types; zombies, humans and admin-mode. Default classes are selected on the player depending on console variables and the class file.

Admin-mode classes are currently incomplete and will be validated, but ignored in the game. This is a special mode in the game, but not the same as admin-only classes. To get admin-only classes set the admin-only flag in the flags attribute.

The list below explains all available class attributes in detail:

Class Attributes

Attribute:	Value type:	Limits/Requirements:
enabled	text	"yes" or "no"
Enables or disables the class. Disabled classes won't show up in the class selection menus. Also, if some attributes failed to validate the class will be disabled.
team	number	0 - 2
Specifies the class type (team ID). Class types are filtered in the class selection menus, so only zombies can use zombie class types, and only humans can use human class types. These are the allowed team IDs: 0 Zombie classes 1 Human classes 2 Admin-mode classes The admin-mode class type sets the player in spectacting like mode, but allow admins to walk around. They can't take or give damage, and they won't affect the game rules in any way. Admin-mode is incomplete and classes of this type is ignored in the game. See the flags attribute for admin-only classes.
team_default	text	"yes" or "no"
Marks the class as the default class for its specified team. This class will be automatically selected on new players when they join the server, depending on what's specified as default in the main configuration file (zr_classes_default_*). If multiple classes in the same team is marked as default the first class marked as default will be used.
flags	number	0 - 3
Special class flags that are stored in a bit field (explained in Log Flags (3.3.1)). Available flags: 1 Admins only Marks the class to be used by admins only. Classes with this option on will not be visible for regular players in the class menu. 2 Mother zombie. Marks the class as a mother zombie class. These classes will be used on mother zombies. Note that zr_classes_default_mother_zombie setting must be set to motherzombies for this flag to be effective. These flags can be used in a combination (1 + 2), so it could be a mother zombie class for admins only.
group	text	Name of a valid SourceMod group
Rescrict class to members of this SourceMod group. Useful for making VIP-only classes. Leave blank to allow everyone to use this class.
name	text	Unique, not empty, max 64 charact.
A unique name for the class that is displayed in the class selection menus. Cannot be empty. If multiple classes have the same name, the first one found is used. This name is also refered to by cvars that set default classes.
description	text	Max 256 characters, not empty
The description of the class, used in class selection menus. Cannot be empty.
model_path	text	Max 256 characters, not empty
Model file path to use on the player, relative to the "cstrike" folder. There are a few presets supported by this attribute: default Use default CS models. The one players select when selecting team. random Selects a random public or admin model for the current team. Admin models are only applied to admins. random_public Selects a random public model for the current team. random_admin Selects a random admin model for the current team. Model permissions will be ignored. random_hidden Selects a random hidden model for the current team. random_mother_zombie Zombies only. Selects a random mother zombie model. no_change Don't change model. Use this setting to keep default Counter-Strike: Source model, or to fix a compatibility issue with other plugins that change model on players.
alpha_spawn	number	0 - 255
The initial transparency value on the player, where 255 is fully visible and 0 is invisible.

At least one zombie class and one human class with no special flags set is required. Otherwise the plugin will fail to load.

Requirements:

There are several console variables to set default class settings for players. Place these console variables in the main configuration file:

cfg/sourcemod/zombiereloaded/zombiereloaded.cfg

And/or in a map config file:

cfg/sourcemod/zombiereloaded/<map name>[.post].cfg

Example map config files:

cfg/sourcemod/zombiereloaded/zm_panic.cfg
cfg/sourcemod/zombiereloaded/zm_panic.post.cfg

Class Console Variables

Console variable:	Default:
zr_config_path_playerclasses	"configs/zr/playerclasses.txt"
Specifies what class configuration file to load. Several class templates can be used with map configurations. Path is relative to "sourcemod". If used in map configuration files this console variable must be placed in pre map configuration files. Post configuration files won't have any effect because the class module is already done loading.
zr_classes_spawn	0
Re-display class menu every spawn. Options: 0 or 1
zr_classes_random	0
Assign random classes to all players each round. This setting overrides zr_classes_save. Options: 0 or 1
zr_classes_change_timelimit	20
The time limit to change human classes with instant change after spawning. So humans don't have to set class before spawning. Time is in seconds.
zr_classes_save	1
Save players' class selections in server cookies. Class selections are restored next time players connect. This setting overrides zr_classes_default_*, but on first-time connecting players the default classes are assigned. This setting also override zr_classes_*_select. If players have saved class indexes in cookies they will be restored. Disabling this option won't erase saved settings, they just won't be restored when players connect. Options: 0 or 1
zr_classes_default_zombie	"random"
Default zombie class selected for all players when they connect. Options: <class name> Specify a class name to use as default zombie. "default" Use the default class in the class configuration. "random" Select a random zombie class from the class configuration.
zr_classes_default_mother_zombie	"motherzombies"
Default mother zombie class to be set on mother zombies. If no mother zombie class exist it will use the class selected by the player. Options: <class name> Specify a class name to use as default mother zombie. "random" Select a random regular zombie class. "motherzombies" Select a random zombie class with mother zombie flag. "disabled" No change. Use the zombie class selected by the player.
zr_classes_default_human	"random"
Default human class selected for all players when they connect. Options: <class name> Specify a class name to use as default human. "default" Use the default class in the class configuration. "random" Select a random human class from the class configuration.
zr_classes_default_admin	"random"
Note: This feature is incomplete! Default admin-mode class selected for all players when they connect, if found. This feature is incomplete and ignored. Do not confuse this with admin-only classes. Admin-mode is a special spawn mode for admins. Options: <class name> Specify a class name to use as default admin-mode class. "default" Use the default class in the class configuration. "random" Select a random admin-mode class from the class configuration.
zr_classes_zombie_select	1
Allow players to select zombie classes. Disable this option to force certain classes on players depending on what zr_classes_default_zombie is set to. Options: 0 or 1

Allow players to select human classes. Disable this option to force certain classes on players depending on what zr_classes_default_human is set to. Options: 0 or 1
zr_classes_admin_select	1
Note: This feature is incomplete! Allow admins to select admin classes. Disable this option to force certain classes on admins depending on what zr_classes_default_admin is set to, - and if admin mode is enabled on the player. Options: 0 or 1

Classes can be modified after they're loaded. This is useful in map configs to do stuff like scaling knockback to tune map balance.

All attributes can be modified, and some can also be scaled with a multiplier. The value in the original class cache is multiplied with the specified value and written back to the modified cache.

When multiplying, the value is always based on the original value, not multiplying the earlier multiplied value. This also makes it easy to restore the original value.

Making a balanced zombie map is difficult, and all maps have different balance. The knock back and other settings may work fine on one map, but not on other maps. This is where multipliers are useful.

With class attribute multipliers, numeric class attributes can be scaled and configured with map configuration files. There's a set of multipliers for both humans and zombies.

Warning: Currently these multipliers aren't validated, so using too high or negative values may cause unexpected behaviour, or even crash the plugin.

Attribute multipliers are set using this console command:

Attribute Multiplier Command

Syntax:
zr_class_set_multiplier <team> <attribute> <value>
Sets the multiplier on a class attribute. Parameters: team What multiplier set to use. Options: "zombies" or "humans" attribute A numeric class attribute. See Class Attributes (3.7.2) for details on attributes. Valid attribute multipliers: health health_regen_interval health_regen_amount speed jump_height jump_distance Multipliers for zombies only: napalm_time health_infect_gain knockback value Value to set, or multiplier if a multiplier.

Multipliers can also be adjusted in the zombie admin menu, but the changes aren't saved. The menu is useful for finding the correct value, and then use it in a map configuration file.

While testing or adjusting class attributes they must be reloaded before they will be effective. This only applies to players who already are the same class.

Reload Attributes Command

Syntax:
zr_class_reload <target>
Refreshes the player cache and reloads class attributes on one or more players. Parameters: target Target player(s) to refresh cache on. A name or a SourceMod target specifier.

For debug purposes class attributes also can be dumped.

Dump Attributes Command

Syntax:
zr_class_dump <cachetype> <index|targetname>
Dumps class data at a specified index in the specified cache. Parameters: cachetype Cache to read from. Cache types: "original" Unmodified raw class data. "modified" Modified class data with multipliers. "player" Player cache, with multipliers. index|targetname Class index, or name of player if "player" cache type is used.

Dumping multipliers is another command for debug purposes. It will dump the current state of multipliers.

Dump Multipliers Command

Syntax:
zr_class_dump_multipliers <team>
Dumps class attribute multipliers for the specified team. Parameters: team The multiplier set to dump. Valid options are: "humans" or "zombies"

The weapon module can be used to restict weapons or scale knockback.

Weapon attributes are stored by default in:

addons/sourcemod/configs/zr/weapons.txt

Custom file may be specified in the console variable "zr_config_path_weapons". If used in per map configuration files it must be in a pre configuration file.

These are the allowed attributes:

Available commands for managing weapon restrictions. These can be used in the main configuration file, or on a per-map basis with map configuration files.

Weapon Commands

Syntax:

Hit group configuration makes it possible to disable damage or adjust knock back per hit group. This is useful for fine tuning game balance.

The hit group configuration file is a file in Valve's key/value format with the root key "hitgroups" and a sub key for each hit group.

The default file is:

addons/sourcemod/configs/zr/hitgroups.txt

Hit Group Commands

Syntax:
zr_hitgroup <hitgroup name> [value]
Toggles or sets if a zombie's hitgroup can be damaged. Parameters: hitgrup name Name of the hit group to adjust. Options: generic head chest stomach leftarm rightarm leftleg rightleg gear value Optional. Enable hit group damage. Default action is to toggle setting. Options: 0 or 1

knockback	decimal	-
The knock back multiplier for the hitgroup. 1.0 for no change.

The infection module handles all infection events and does random infection on mother zombies. It's the core part of the plugin that creates this human vs. zombies game.

Number of mother zombies is based on a ratio setting, so on server with many players more mother zombies will be spawned than on a server with few players. Server admins can adjust this ratio to tune game balance.

In addition several infection effects can be enabled or disabled.

These are the console variables for the infection module:

Infection Console Variables

Console variable:	Default:
zr_infect_mzombie_ratio	5
Mother zombie ratio. Every random n-th player is infected. In this case it's 5 where every fifth player will be infected. If it's set to 0 there will only be 1 mother zombie every time. Note that this is NOT a percentage value. The ratio 5 does not mean 5%, but every fifth player. To get the percentage you need to do ratio / player slots. Like 5 / 24 = 0.20 ⇒ 20% infection rate. Conversion formula from percent to ratio: ratio = (percent / 100) * player slots Decimals are stripped from the ratio because it's a integer value. Options: 0 or a positive number up to max server slots
zr_infect_mzombie_respawn	0
Teleport mother zombies to spawn place when infected. Options: 0 or 1
zr_infect_spawntime_min	30.0
Minimum time when mother zombies spawn. Time is in seconds.
zr_infect_spawntime_max	50.0
Maximum time when mother zombies spawn. Time is in seconds.
zr_infect_consecutive_block	1
Blocks players from being mother zombie twice in a row. Options: 0 or 1
zr_infect_weapons_drop	1

Overlays are pictures displayed on players' screen on certain events. However, these overlays require DirectX 9 or newer to work. Players with lower DirectX version won't see these overlays.

Since these overlays doesn't last forever, they must be redisplayed at a certain interval. A refresh once per second seems to be enough.

When the round ends, overlays for either humans or zombies are displayed, depending on the winning team.

Overlays are also used as a class attribute, like the zombie vision effect.

The anti-stick system is a automatic no-block system that turn off collisions on players that are stuck together, and enable collision again when they're unstuck.

(Note: This file is obsolete!) To know if players are stuck, it needs some extra info about each model used in the game. Data for these models are stored in the following file (relative to "sourcemod" folder):

data/antistick.dat

Volumetric Features is a way to do various stuff on players when they enter custom created volumes in a map. A volume is rectangular and is created by using two coordinates in the map that defines the three-dimensional area.

This is a visualized volume where the red border is the volume, and the blue or green circles are examples of what points in the map that could be used.

Known issues/bugs:

• Volumes placed in spawn areas won't take effect on them until they leave the area and go back in. There's a bug where it doesn't apply to spawned players.
• Avoid overlapping volumes of same type. There's currently no conflict handling and whichever volume the player enter or leave last will be triggered.

To create a volume go into spectactor mode (or no-clip). Enable position display in the client (cl_showpos 1), the numbers appear in the top right corner of the scteen. Visualize a rectangular area and move to one of its corners. Get the x, y and z coordinates (make sure you don't miss the "-" if it's a negative number). Go to the diagonally oposite corner, in the oposite height and get the second set of coordinates.

Use the zr_vol_add console command in map configs to add volumes.

Short summary:

1. Go into spectator mode or no-clip
2. Enable position display: cl_showpos 1
3. Go to one of the corners, get the coordinates
4. Go to the diagonally oposite corner, in the oposite height and get the second set of coordinates.
5. Use these coordinates in the zr_vol_add command along with additional attributes.

Note: Make sure all volumes start a little bit below players' feet so they are covered by the volume. Otherwise nothing will happend.

Each volume has a set of standard attributes that tell how it should behave and look like. In addition each feature has a set of attributes. All attributes have default values and are not required, except the type attribute.

These are the generic attributes and apply to all volumes:

Generic Volume Attributes

Attribute:	Value type:	Default:
type	text	-
Note: This attribute is required! Specified the volumetric feature type. Valid options: anticamp Anti-Camp volume. classedit Class editor volume.
teamfilter	text	"all"
Sets the team filtering settings. Valid options: all Applies to all players. humans Applies to humans only. zombies Applies to zombies only.
delay	number	0
Trigger delay. Number of seconds to wait when a player enter the volume before triggering actions. Time is in seconds.
effect	text	"none"
Note: Incomplete, this attribute is ignored. What effect to apply to the volume Valid options: none No effect. wireframe Draw a wireframe. smoke Put smoke in the volume. fire Put fire in the volume.
effect_color	text	"0,0,0"
Note: Incomplete, this attribute is ignored. Color of the effect. RGB format, represented by three numbers from 0 to 255 separated by a comma. Syntax: <red>,<green>,<blue>
enabled	boolean	1
Set the initial enabled setting on the volume. Usually this attribute won't be used.

Volume Commands

Syntax:
zr_vol_add <x1> <y1> <z1> <x2> <y2> <z2> <type> [params]
Creates a rectangular volume in the map. Parameters: x1, y1, z1 First set of coordinates. x2, y2, z2 Second set of coordinates. type Volumetric feature type. Described in Volume Attributes. params Additional key-value chain of volume attributes, separated by space. Syntax: attribute=value attribute=value ...
zr_vol_remove <volume index>
Removes an existing volume in the map. Parameters: volume index Zero-based index of volume (ID) to remove.
zr_vol_list [volume index]
Lists existing volumes in the map, or dumps volume details. Parameters: volume index Optional. Zero-based index of volume (ID) to dump.
zr_vol_dumpstates <userid|targetname>
Dumps a list of all volumes and a indicator whether the target is in it or not. Parameters: userid|targetname A SourceMod target string to a single player.

The anti-camp feature can be used to force players to leave areas that are considered unfair or not allowed. It uses a timer to trigger actions at a specified interval. In addition warning messages can be displayed to player that enter the volume.

Do not overuse anti-camp volumes in maps, players don't like that. Instead look for alternate solutions like using a class editor volume to set knock back in tubes/vents.

Anti-Camp Attributes

Attribute:	Value type:	Default:
interval	number	5
Trigger interval. How often to apply actions on players in the volume. Time is in seconds.
action	text	"damage"
What kind of action to apply. Valid options: none Do nothing. Useful for just giving warning messages. damage Hurt player. slay Kill player. drug (Incomplete!) Drug player. Players will be un-drugged when leaving volume. ignite Set player on fire. Players will be extinguished when leaving volume.
amount	decimal	5.0
Specifies amount to apply depending on action type. Amount type for action: none (ignored) damage Health points slay (ignored) drug Time in seconds ignite Time in seconds
warning	text	"chat"
Where to show warning message. Valid options: none Don't show a warning message. chat Display in client's chat area. center Display warning text centered on the screen. menu Display warning in a menu panel, stays open for 30 seconds or when closed.
message	text	""
Note: Incomplete, this attribute is ignored. Use custom warning message (max 255 byte). Leave blank to use default warning message.

(Docs incomplete.)

Zombie:Reloaded use SourceMod to authenticate players. There are two ways to do this; flag based or group based. With flag authentication a certain admin flag is required to be set, and with group authentication the player must be member of a certain group to do certain types of operations.

The reason to use group authentication could be to let admins have full access in SourceMod so they get access to configure all plugins, but still limit access to commands in Zombie:Reloaded. When using flag authentication the permissions will be global across all plugins, including Zombie:Reloaded.

Permission Console Variables

Console variable:	Default:
zr_permissions_use_groups	0
Use group authentication instead of flags to access admin features. Generic admin flag is still required on some features. Options: 0 or 1

(bunny jump)

(almost invisible zombies, act as a spy and surprise humans)

There are glitches and simplified physics stuff that can be used to get an advantage. Some servers may not allow all of these tricks because they could be unfair.

(bad thing to do, and should not be allowed)

Realistic physics in multiplayer games is a expensive task for the server and it appears to be laggy for players. The solution to this is simplified physics on props (that is simplified collision detection).

Some props aren't solid but pushes players away from it's origin (center of the object). This is NOT a engine bug, but a simplified solution. These props are useful to _delay_ zombies in barricades, but they're still fair to use. If players got enough speed they can run and jump through them.

There's another trick that works quite good if the knock back is balanced correctly. If a player look straight down or straight up it's possible to simply walk through non-solid props, or at the same time, jumping slowly through them.

This simplified physics is used by default on regular Counter-Strike: Source maps. There's something called turbo physics which is enabled on most zombie servers, where all props are solid so players can stand on them. Players can't push props, but move them by shooting or using their use key (E by default) while aiming at the object.

When zombies have to crouch to enter a area where humans camp (like tubes and vents), jumping fast might help.

There are several error levels that are handled differently in the plugin. Fatal errors will stop the plugin, errors might disable features, and warnings will usually fall back to a default action.

Unable to load extension "zrtools.ext.so": Could not find interface: IPlayerManager

ZR Tools in beta 1 was compiled based on a development snapshot of SourceMod so it requred a newer version of SourceMod than the latest stable release at that time. It's now compiled based on SourceMod 1.2.

Solution: Update SourceMod.

"ERROR" models or pink (checkerboard) models

Big "ERROR" models on zombies/humans is usually caused by missing files. Common causes are:

• Model files missing in download list
• Model files missing on server
• Typo in model list
• Typo in class configuration ("model_path" attribute)
• Missing or incorrect whitelist settings on pure servers

Model not precached

This is usually caused by classes that specify models that isn't added to the model list.

The model list is limited and models after that limit is ignored. Check error logs for warnings about full model list.

Freeze/lag on infection

When a human get infected the server freeze for a short amount of time. This might be caused by too detailed models, or a cache problem.

Solution: Try "sv_forcepreload 1" in the server's configuration file. "cl_forcepreload 1" on the client might help too, but servers can't set that console variable on clients.

Bouncing props

This is bug in the Source engine and we can't do anything about it, but avoid stuff that is known to trigger this bug.

Anti-Stick might trigger this bug in some cases, but it also might depend on the map.

Resources like models, materials and sounds must be made available for download to players on the server. Zombie:Reloaded need a list of what files do be downloaded on the players' client. Currently it's only two lists; models and downloads.

Note: The ambiecne sound file doesn't need to be listed.

When adding models, update following modules:

A guide on tuning knock back. It will help finding the default knock back that is used as base value for all classes.

1. Make a new zombie class with normal Counter-Strike: Source settings:

   fov	90
   speed	300
   knockback	1.0
   jump_height	1.0
   jump_distance	1.0

2. Disable hit groups module.
3. Set all weapon knock back multipliers to 1.0 in weapon configuration.
4. Join the game and get someone to help. Use that new zombie class.
5. Open knock back multiplier menu and leave it open: !zadmin > Class Multipliers > Zombies > Knock Back
6. Experiment by increasing or decreasing multiplier to get a good feeling on its sensitivity. Then start testing in an open area to make a good balance between zombies and humans. Also test it while climbing on boxes.
7. Once the balance is good, note the multiplier value. This is the actual value since all other multipliers are 1.0. This value will be used as base knock back and can be set on all zombies. Currently there's no in-game multiplier menu for hit groups, but it can be reloaded after changes are made, whithout restarting the server.
8. Set knock back on other zombie classes in class configuration based on this vlaue, whether they should be stronger or weaker.
9. Enable hit groups and adjust the knock back multiplier per hit group. Note that it's a multiplier and there should be only tiny changes from 1.0.
10. Adjust weapon knock back in weapon configuration. The best is to keep these as close to 1.0 as possible. Knock back also depends on how much damage that's done, so pistols could have increased values, and shot guns can be decreased.
