Trigger portal cleanser

Template:Portal series brush It removes objects and portals when the player touches it. It is used to create the "Material Emancipation Grid" / "Fizzler" particle-field in Portal.

Bug:In Portal, the player's T-posed corpse is visibly dissolved when dying inside this entity. In versions of Source prior to Source 2013, this would crash the game.  [todo tested in ?]

Bug:Portal shot blocking is based on the entity's bounding box, causing diagonal or concave cleansers to block portal shots in cases where they seemingly shouldn't. Portal and object fizzling works as expected.  [todo tested in ?]

Tip:To directly apply the dissolve effect to a specific entity, use env_entity_dissolver, or for cubes fire the Dissolve input.

Tip:Use trigger_physics_trap to dissolve entities without affecting portal placement.

Note:Entities being dissolved by env_entity_dissolver or trigger_physics_trap don't float, unlike entities dissolved by trigger_portal_cleanser.

Keyvalues

Visible ([todo internal name (i)]) <boolean> (in all games since )

If the fizzler is visible. This also controls if the sound effects are played when powered on and off.

Use Scanline ([todo internal name (i)]) <boolean> (in all games since )

If the field uses a scanline. This only works correctly for vertical fields aligned to an axis.

Render in Fast Reflections (drawinfastreflection) <boolean> (in all games since )

If enabled, this entity will render in fast water reflections (i.e. when a water material specifies $reflectonlymarkedentities) and in the world impostor pass.

BaseTrigger

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

Flags

BaseTrigger

Everything (not including physics debris) : [64] Clients (Survivors, Special Infected, Tanks ) : [1] Only clients in vehicles : [32] Only clients *not* in vehicles : [512] Disallow Bots (removed since ) : [4096] NPCs (Common Infected, Witches ) : [2] Only player ally NPCs : [16] Only NPCs in vehicles (respects player ally flag) : [2048] Physics Objects (not including physics debris) : [8] Physics debris (include also physics debris) : [1024] Pushables (Passes entities with classname func_pushable) : [4]  Deprecated. Equivalent to using Everything + filter_activator_class that filters func_pushable.

Inputs

FizzleTouchingPortals  (in all games since )

Cause any portals in our volume to immediately fizzle.

Reflection:

DisableDrawInFastReflection  (in all games since )

Turns off rendering of this entity in reflections when using $reflectonlymarkedentities in water material.

EnableDrawInFastReflection  (in all games since )

Turn on rendering of this entity in reflections when using $reflectonlymarkedentities in water material.

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

OnDissolve

Fired whenever an entity is dissolved by the trigger.

OnDissolveBox

Fired whenever an entity named box is dissolved by the trigger.

OnFizzle

Fired whenever portals are fizzled by the trigger.

OnPrimaryHit  (only in )

Fired whenever the trigger has been hit by a primary shot from weapon_portalgun.

OnSecondaryHit  (only in )

Fired whenever the trigger has been hit by a secondary shot from weapon_portalgun.

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.
