Picking Units With specific Facing angle

[junicobakura]

how do you pick units whos facing the caster or position of the caster?

 

[Dinowc]

set angle1 = angle between position of Picked unit and position of Casting unit + 360.
set angle2 = Picked unit's Facing Angle + 360.
if angle1 + 10. > angle2 and angle1 - 10. < angle2 then
--UNIT IS FACING THE CASTER--

ignore the leaks

are the +10 and the -10 the angle wideness?

 

[DrEvil]

yes, which leads to a 20 degree angle for the unit to be facing
from -10 to +10 = 20
+10 is going counter-clockwise - left of the unit
-10 is going clockwise - right of the unit

so if he was blind in the left eye it would be from -10 to 0 ( theoretically )
