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 ?]

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

Tip:In Portal, use trigger_physics_trap to dissolve entities without affecting portal placement.

Note:In Portal, entities being dissolved by env_entity_dissolver or trigger_physics_trap are solid and 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

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 when a box is dissolved by the trigger.

Note:In order for this output to fire, the object it dissolves must have the targetname box.

OnFizzle

Fired whenever portals are fizzled by the trigger.

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.
