info_map_parameters

info_map_parameters is a point entity available in the following Source engine games: Left 4 Dead, Left 4 Dead 2, Counter-Strike: Source, Counter-Strike: Global Offensive.

Entity description

It defines game-specific map parameters.
It specifies which team can buy and C4 explosion radius in Counter-Strike: Source and Counter-Strike: Global Offensive.
In Left 4 Dead series, it defines the density of weapons & items.

Keyvalues

Targetname:

Name (targetname) <string>

The targetname that other entities refer to this entity by.

Entity Scripts (vscripts) <scriptlist> (in all games since )

Space delimited list of VScript files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions.

Script think function (thinkfunction) <string> (in all games since )

Name of a function in this entity's script which will be called automatically every 100 milliseconds (ten times a second) for the duration of the script. It can be used to create timers or to simulate autonomous behavior. The return value (if present) will set the time until the next call.

Note:Try to avoid expensive operations in this function, as it may cause performance problems.

Angles:

Pitch Yaw Roll (Y Z X) (angles) <angle>

This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.

Counter-Strike: Source / Counter-Strike: Global Offensive

Team that can buy <integer>

Defines which teams can buy weapons

C4 Explosion Radius <integer>

Overrides the default radius of the explosion when the C4 bomb explodes. Max range is 2048.

Pet Population <integer>

Note: Chickens won't spawn automatically unless the map has a Navigation Mesh.

Use Normal Spawns in Deathmatch? <integer>

Set to true if the map should use the mapper-placed spawn points instead of generating random ones. ( only)

Disable Autogenerated DM Spawns? <integer>

Set to true if you want to manually place info_deathmatch_spawns and not have the engine generate them. ( only)

Bot Max Vision Distance <integer>

Sets the maximum distance bots can see enemies. Default is -1, unlimited. ( only)

Targetname:

Name (targetname) <string>

The targetname that other entities refer to this entity by.

Entity Scripts (vscripts) <scriptlist> (in all games since )

Space delimited list of VScript files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions.

Script think function (thinkfunction) <string> (in all games since )

Name of a function in this entity's script which will be called automatically every 100 milliseconds (ten times a second) for the duration of the script. It can be used to create timers or to simulate autonomous behavior. The return value (if present) will set the time until the next call.

Note:Try to avoid expensive operations in this function, as it may cause performance problems.

Angles:

Pitch Yaw Roll (Y Z X) (angles) <angle>

This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.

Inputs

UpdateCvars

Stuff values from this entity into cvars for tweaking

Targetname:

Kill

Removes this entity from the world.

KillHierarchy

Removes this entity and its children from the world.

Note:Entities already remove orphaned children upon being removed, but this input removes all children on the same frame, being marginally faster than Kill.

AddOutput <string>

Adds a keyvalue/output to this entity. It can be potentially very dangerous, use with care.
KV Format: <key> <value>
I/O Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>

FireUser1 to FireUser4

Fire the OnUser outputs; see User Inputs and Outputs.

Use  !FGD

Same as a player invoking +use; may not do anything depending on the entity. Can also be invoked by firing an output that does not specify an input.

RunScriptFile <script> (in all games since )

Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.

RunScriptCode <string> (in all games since )

Execute a string of VScript source code in the scope of the entity receiving the input. String quotation may be needed when fired via console.

Bug: In , the code is executed in the script scope of the entity that fires the output, not the one receiving the input.

Warning: Never try to pass string parameters to a script function with this input. It will corrupt the VMF structure because of the nested quotation marks, which then must be removed manually with a text editor.

CallScriptFunction <string> (in all games since ) !FGD

Execute a VScript function in the scope of the receiving entity.

SetLocalOrigin <coordinates> (in all games since ) !FGD

Send this entity to a spot in the map. If the entity is parented to something, it will be offset from the parent by this amount.

SetLocalAngles <angles> (in all games since ) !FGD

Set this entity's angles.

Outputs

Targetname:

OnUser1 to OnUser4

These outputs each fire in response to the firing of the like-numbered FireUser1 to FireUser4 Input; see User Inputs and Outputs.

OnKilled  (only in )

This output fires when the entity is killed and removed from the game.

Useful console commands

director_solve_item_density

Pass the number of items you'd want in this map and this spits out the map density value.
