How to check/detect if a unit is behind the back

[-OverpoweR-]

Hello guys, i am chilling here messing around with the editor, and i wanna make a spell for which i need to detect when a unit is behind Unit_1 so that he can do actions afterwards, hope to hear from someone soon

Hmm, don't quote me on this, but first you have to decide what you consider as one unit being behind another unit.

I would say its 90 degrees, so 45 degrees on either side behind the unit
take a look at this pic if it doesn't make sense yet

So, in the picture: Unit A is facing south, so using Unit A as an origin, any unit unit standing
withing that 90 degrees would be considered behind Unit A.

Now here's where my memory of the editor becomes a bit sketchy,
1) You'll want to find the angle that Unit A is facing with regards to the map, we'll
call it angle A.
2) Now you want to find the angle between Unit A and Unit B (the unit that casts the spell),
we'll call that angle B
3) Now check if angle B is smaller than angle A + 225 degrees, and greater than
angle A + 135

Hope it helps

EDIT: Hmm, looks like my image aint working, ill upload the image as well
