Checking if a unit is facing a point

[TideOfChaos]

I need a way to see if a unit is facing a point.
More spefically, if it is facing the source of damage.
Or, if it is easier, source of attacker/caster.

I think you need a condition like this :

RabsBJ(GetUnitFacing(GetEentDamageSource())-GetUnitFacing(GetTriggerUnit()))==bj_PI

But I guess it wouldn't hurt to make it with an error marje of +- 30 degrees that is bj_PI/6 .

 function Event_TargetFacingAttacker_Condition takes nothing returns boolean
return RabsBJ(RabsBJ(GetUnitFacing(GetEventDamageSource())-GetUnitFacing(GetTriggerUnit()))-bj_PI)<=bj_PI/6
endfunction

I hope the people making the GetUnitFacing functions made it return radians like normal people .
