[JASS] Need a proper condition

[LexX]

I need a proper condition which checks difference between facing angle of a unit and fixed angle.
I tried some ways to do that, but it worked only when the enemy's position was upper than casters (fixed angle is angle of moving the caster when caster moves to the enemy, that's why it depends on enemy's position), but when the caster's position was upper then the trigger didnt work.
Need smth. like Difference between facings <= 20.

AngleBetweenPoints function can return values from -180 to + 180 while Unit Facing returns from 0 to 360.
To "fix" that,do it like:

if FixedAngle < 0 then
    set FixedAngle = 360.0 + FixedAngle
endif

This will make it return values from 0 to 360.
