float GetAngle (int flags [, int ptr_select])
Gets the angle of the calling actor and the pointer.
Note that this function is to be used where an expression is expected. It is mostly useful when combined with A_JumpIf or Anonymous Functions and can be used in place of such functions like A_JumpIfTargetInLOS.
- flags: Flags can be combined with the | symbol.
- GAF_RELATIVE: The same as setting relative to true.
- GAF_SWITCH: Inverses the angle check; equivalent of the pointer executing the function, but the result goes to the calling actor instead.
- ptr_select: The pointer to examine. Default is AAPTR_TARGET. Must be a pointer other than AAPTR_DEFAULT or AAPTR_NULL. See actor pointers.
Returns the angle in double floatation precision constricted between [-180.0, 180.0].
I.e. if the pointer is directly south of the caller and the check is non-relative, it will return -90. North is 90. West is 180. East is 0.
