trigger_active_weapon_detect

 trigger_active_weapon_detect is a brush entity available in Left 4 Dead 2. It fires an output when touched by a player that has a specific weapon active.

Keyvalues

Weapon To Detect <string>

weapon classname that player must have active

TriggerOnce:

Filter Name (filtername) <filter>

Name of filter entity to test against activators.

EnableDisable:

Start Disabled (StartDisabled) <boolean>

Stay dormant until activated (with theEnableinput).

Base:

Collisions (solid) <choices>

Method of collision for this entity.

• 0: None
• 1: BSP (QPhysics) !FGD
   Bug: In , if an entity using QPhysics collisions is hit by Gel, the game will crash!
• 2: Bounding Box
• 3: Oriented Bounding Box (Use for runtime spawned brush entities meant to be rotated) !FGD
• 4: Oriented Bounding Box but constrained to Yaw only !FGD
• 5: Custom/Test (Usually no collision with anything) !FGD
• 6: VPhysics

Name (targetname) <string>

The name that other entities use to refer to this entity.

Parent (parentname) <targetname>

Maintain the same initial offset to this entity. An attachment point can also be used if separated by a comma at the end. (parentname [targetname],[attachment])

 Tip: Entities transition to the next map with their parents

 Tip: phys_constraintcan be used as a workaround if parenting fails.

Origin (X Y Z) (origin) <coordinates>

The position of this entity's center in the world. Rotating entities typically rotate around their origin.

 Note: Hammer does not move the entities accordingly only in the editor.

Pitch Yaw Roll (X Y Z) (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.

 Note: This works on brush entities, although Hammer doesn't show the new angles.

Classname (classname) <string> !FGD

Determines the characteristics of the entity before it spawns.

 Tip: Changing this on runtime still has use, like making matching an entry in S_PreserveEnts will persist the entity on new rounds!

Flags (spawnflags) <integer> !FGD

Toggles exclusive features of an entity, its specific number is determined by the combination of flags added.

Effects (effects) <integer> !FGD

Combination of effect flags to use.

Flags

TriggerOnce:

•  [1] : Clients

•  [2] : NPCs

•  [4] : Pushables

•  [8] : Physics Objects

•  [16] : Only player ally NPCs

•  [32] : Only clients in vehicles

•  [64] : Everything (not including physics debris)

•  [512] : Only clients *not* in vehicles

•  [1024] : Physics debris

•  [2048] : Only NPCs in vehicles (respects player ally flag)

•  [4096] : Disallow Bots

•  [4096] : Correctly account for object mass (trigger_push used to assume 100Kg) and multiple component physics objects (car, blob...) (in all games since )

 Note: In , flag 4096 is "Correctly account for object mass" for trigger_push only.^[confirm]

Inputs

Trigger:

TouchTest  (in all games since )

Triggers either the OnTouching or OnNotTouching outputs for whether anything is touching this entity.

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 the !caller entity had just exited the trigger volume.

DisableAndEndTouch  (only in )

Disables this trigger and calls EndTouch on all currently-touching entities.

TriggerOnce:

Toggle

Toggles this trigger between enabled and disabled states.

EnableDisable:

Enable

Disable

Enable/disable this entity from performing its task. It might also disappear from view.

Base:

AddContext <string>

Adds to the entity's list of response contexts. Format is <key>:<value>.

AddOutput <string>

Assigns a new keyvalue/output on this entity. For keyvalues, some rely on extra necessary code to be ran and won't work if its simply just changed through this input. There is a strict format that must be followed:

Syntax: 

// Format of changing KeyValues: "AddOutput [key] [value]"
//// Raw text:
"OnUser1" "!self,AddOutput,targetname new_name"

// Format of adding an Output: "AddOutput {targetname}:{inputname}:{parameter}:{delay}:{max times to fire, -1 means infinite}"
//// Raw text:
"OnUser1" "!self:SetParent:!activator:0.0:-1"
// Arguments can be left blank, but the empty blank should still be contained.
//// Raw text:
"OnUser1" "!self:ClearParent::0.0:-1"

ClearContext

Removes all contexts from this entity's list.

ClearParent

Removes this entity from the the movement hierarchy, leaving it free to move independently.

FireUser1 to FireUser4

Fires the respectiveOnUseroutputs; see User Inputs and Outputs.

Kill

Removes this entity and any entities parented to it from the world.

KillHierarchy

Functions the same as Kill, although this entity and any entities parented to it are killed on the same frame, being marginally faster thanKillinput.

RemoveContext <string>

Remove a context from this entity's list. The name should match the key of an existing context.

SetParent <string>

Move with this entity. See Entity Hierarchy (parenting).

SetParentAttachment <string>

Change this entity to attach to a specific attachment point on its parent. The entity will teleport so that the position of its root bone matches that of the attachment. Entities must be parented before being sent this input.

SetParentAttachmentMaintainOffset <string>

As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.

Use  !FGD

Same as a player invoking +use; no effect in most cases.

DispatchResponse <string> !FGD

Dispatches a response to the entity. See Response and Concept.

DispatchEffect <string> (removed since ) !FGD

Dispatches a special effect from the entity's origin; see also List of Client Effects. Replaced by the particle system since .

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 Hammer, using string arguments will corrupt the VMF file's structure, making the file unviewable for the next Hammer session.

Fix: Remove the string argument 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

OnTouchedActiveWeapon

Touched a player who has our weapon active

Trigger:

OnEndTouch

Fired when an entity stops touching this trigger. Only entities that passed this trigger's filters will cause this output to fire. (activator is the exiting entity)

 Warning: This includes entities which are deleted while inside the trigger. In this case activator will be invalid.

OnEndTouchAll

Fires when the last entity in the entity's area exits this trigger or when this entity is disabled. Only entities that passed this trigger's filters are considered. (activator is the last exiting entity)

OnTouching  (in all games since )

OnNotTouching  (in all games since )

Fired when the TouchTest input is called.

TriggerOnce:

OnStartTouch

Fired when an entity starts touching this trigger. The touching entity must pass this trigger's filters to cause this output to fire. (activator is the toucher)

OnTrigger

Fired repeatedly with a delay when an entity is in this trigger's volume. Delay is defined by Delay Before Reset key.
