trigger_portal_button
trigger_portal_button
is a point entity available in the Portal games. It is the actual trigger used by a prop_floor_button
, prop_floor_cube_button
, or prop_floor_ball_button
to detect objects. When placed in a map directly, the game will crash as the entity keeps a reference to the button it is tied to, which can only be set through code. A trigger_multiple
should be used instead as it functions almost identically.
Tip:The auto-generated triggers use their oriented bounding box as the detection area, so the
SetSize()
VScript function can be used to resize the trigger.Contents
Keyvalues
- Delay Before Reset
(???)
<float> - Delay in seconds before OnTrigger can fire again, 0 defaults to 0.2. If set to -1, it will kill itself when triggered (as trigger_once), which means outputs like OnEntireTeamStartTouch can never fire.
BaseTrigger:
- Filter Name
(filtername)
<filter> - A filter entity to test potential activators against.
- Start Disabled
(StartDisabled)
<boolean> - Stay dormant until activated (with the
Enable
input).
