point_anglesensor

Code classes:

point_anglesensor is a point entity present in all Source games. It detects if an entity points toward another for a period of time.

Flags[edit | edit source]

1: Use target entity's angles (NOT position) - Instead of measuring if Target Entity is pointing at Look At Entity, it measures if they're facing in the same direction.

Target Entity Name (target) <target_destination>: Name of the entity whose angles will be sensed.
Look At Entity (lookatname) <target_destination>: Entity to check if Target Entity is pointed towards.
Duration (duration) <float>: How long Target Entity must look at Look At Entity to fire OnFacingLookat.
Tolerance (tolerance) <float>: How many degrees off Target Entity can point at Look At Entity while still counting as looking at it. 0 means the target must point perfectly at the other entity. 180 means the direction can be anything.

Start Disabled (StartDisabled) <boolean>: Stay inactive until Enabled.

Test: Immediately fires OnFacingLookat or OnNotFacingLookat depending on if the Target Entity is looking at Look At Entity within Tolerance.
SetTargetEntity (Not in FGD) <target_destination>: Sets Target Entity.

FacingPercentage <float>: Constantly fires. Automatically puts a value (closer to 1.0 when pointing at Look At Entity and closer to 0.0 when not) as the input parameter, unless overridden by the mapper. (Hits 0 when not within Tolerance.)
TargetDir <vector>: Fires every time the Target Entity changes its angle. Automatically puts the new angles as numbers from -1.0 to 1.0 as the input parameter, unless overridden by the mapper.; Note: This is not very useful, as there are practically zero inputs that take a vector.
OnFacingLookat: Fires when the Target Entity has looked at Look At Entity within Tolerance for Duration, or when it's looking at it when the entity is sent the Test input.
OnNotFacingLookat: Fires when the Target Entity is not looking at Look At Entity within Tolerance when the Test input is sent.
