DeltaYaw:Float32 src_entity:Int32, dest_entity:Int32

Parameter	Mode	Type	Default	Description
src_entity	In	Int32	required	The entity that should turn.
dest_entity	In	Int32	required	The entity it should look at.

Returns: The turn needed, in degrees.

Description

Tells you how far an entity has to turn around its vertical axis to look at another entity. The result is in degrees, between -180 and 180. A positive angle is a turn to the left, as with EntityYaw, so adding the result to the current yaw makes the entity face the target. It only looks at the horizontal direction; the height difference is covered by DeltaPitch.

SetBuffer BackBuffer()

turret = CreatePivot()
target = CreatePivot()
PositionEntity target, 5, 0, 5

; The target is up front and to the right, so the turret turns right by 45 degrees (-45).
