Func buyzone

Buyzones usually touch all player spawns of an entire team.

func_buyzone is a brush entity available in Counter-Strike: Source and Counter-Strike: Global Offensive.

Note:This entity's trigger functionalities are !FGD but can be used, such as the StartDisabled keyvalue and the Enable/Disable/Toggle inputs. To use this entity's inherited trigger I/O (OnStartTouch, ...), set its spawnflags keyvalue appropriately (default is 4097). To add all of this in Hammer, see below.

Bug: By default, this entity has the inputs SetEnabled/SetDisabled in Hammer, but it actually doesn't; Using these has no effect! Use Enable/Disable/Toggle instead. This can be fixed by editing csgo.fgd, searching for func_buyzone and replacing the incorrect input names. (The FGD code below fixes this differently.)  [todo tested in ?]

In code, it is represented by theCBuyZoneclass, defined in thefunc_buy_zone.cppfile.

Entity Description

It is used to define areas where players of different teams can open the buy menu to purchase weapons and equipment.

If a player touches the volume of this entity and his team equals the team of this entity, then he is allowed to buy. If this entity has the team 0 or -1, then any or no player can buy inside this entity's volume, respectively.

Tip:The SetTeam input can be used to change the buying team in-game.

Note:Setting this entity's team to -1 and Disableing it have the same effect, just that these are independent operations.

Keyvalues

Team number (int) (TeamNum) <integer>

The team that can use the buyzone.

-1	No one
0	Everyone
2	Terrorists
3	Counter-Terrorists
other	No one

Note: This keyvalue is only used when this entity is spawned, so changing it with AddOutput has no effect. The actual keyvalue that determines the buy team is teamnumber.

BaseTrigger

Filter Name (filtername) <filter> A filter entity to test potential activators against. Start Disabled (StartDisabled) <boolean> Stay dormant until activated (with theEnableinput).

Inputs

SetTeam <integerRedirectInput/integer>

Sets the team of this entity, which also sets the team that is allowed to buy.

SetTeam_TerroristOnly  (only in )

Restrict buyzone to Terrorists only. Equivalent to SetTeam 2.

SetTeam_CTOnly  (only in )

Restrict buyzone to Counter-Terrorists only. Equivalent to SetTeam 3.

SetTeam_AllTeams  (only in )

Allows all teams to use the buyzone. Equivalent to SetTeam 0.

SetTeam_None  (only in )

Allows no team to use the buyzone, effectively disabling it. Equivalent to SetTeam -1.

BaseTrigger

Toggle Toggles this trigger between enabled and disabled states. Enable Enable trigger Disable Disable trigger TouchTest  (in all games since ) Triggers either the OnTouching or OnNotTouching outputs for whether anything is touching this entity. Bug:Sleeping prop_physics will never fire "OnTouching". Also applies to entities using prop_physics as base.  (tested in: ) StartTouch  (in all games since ) !FGD Behave as if the !caller entity had just entered the trigger volume. Accepts non-physical entities. EndTouch  (in all games since ) !FGD Behave as if !caller had just exited the trigger volume. DisableAndEndTouch  (only in ) Disables this trigger and calls EndTouch on all currently-touching entities.

Outputs

BaseTrigger

OnStartTouch !activator = entity that caused this output !caller = this entity Fired when a valid entity starts touching this trigger. OnStartTouchAll !activator = entity that caused this output !caller = this entity Fired when a valid entity starts touching this trigger, and no other entities are touching it. If there are any other entities touching the trigger when a new one begins to touch, only OnStartTouch will fire. OnEndTouch !activator = entity that caused this output !caller = this entity Fired when a valid entity stops touching this trigger. Note:Will also fire for entities touching it when trigger is disabled via Disable input Warning:This includes entities which are deleted while inside the trigger. In this case !activator will be invalid. Warning:OnEndTouch can fire before OnStartTouch under certain circumstances[How?] where both are fired on the same tick and each have the same delay. Fix:Add a slight delay to OnEndTouch. OnEndTouchAll !activator = entity that caused this output !caller = this entity Fired when all valid entities stop touching this trigger. OnTouching  (in all games since ) !activator = !caller = this entity Fired if something is currently touching this trigger when TouchTest is fired. OnNotTouching  (in all games since ) !activator = !caller = this entity Fired if nothing is currently touching this trigger when TouchTest is fired.

FGD Code

This code...

• replaces its base class with Trigger which effectively adds trigger properties such as the keyvalue StartDisabled, the inputs and outputs Enable/Disable/Toggle/OnStartTouch/... and the trigger flags (1: Clients, ...).
• adds the input TouchTest and the outputs OnTouching/OnNotTouching as seen in trigger_multiple of base.fgd.
• removes the invalid inputs SetEnabled, SetDisabled.

Replace the corresponding lines of cstrike.fgd or csgo.fgd near func_buyzone with this.

Note: The inputs SetTeam_[...] don't exist, so make sure not to add those four lines.
