Unit facing unit question again

vile	Sorry, I suck when it gets to angles. Now I need a condition where a unit is facing directly at another unit, and it will return true, without taking in matter the target's facing.

JASS:

local unit facer = YOUR_UNIT
local unit target = TARGET
local real angle = bj_RADTODEG * Atan2(GetUnitY(target) - GetUnitY(facer), GetUnitX(target) - GetUnitX(facer)))
if (angle < 0) then
    set angle = angle + 360
endif
return (angle = GetUnitFacing(facer))

That doesnt work.

blu da noob's function works for a unit facing a unit, like this: -> <-

here it is

JASS:

local real f1 = GetUnitFacing(yourunit)
local real f2 = GetUnitFacing(targetunit) + 180.
local real angle = AngleBetweenUnits(yourunit,targetunit) //Use your equivalent of this
local real diff1 = RAbsBJ(f1-f2)
local real diff2 = RAbsBJ(f1-angle)
local real tolerance = 30. //How far it can be from exact facing

    return ( diff1 <= tolerance or diff1 >= (360 - tolerance) ) and ( diff2 <= tolerance or diff2 >= (360 - tolerance) )

I want the condition to be true if the target faces the caster, and it doesnt matter which angle the caster faces.

JASS:

local real f1 = GetUnitFacing(yourunit)
local real angle = AngleBetweenUnits(yourunit,targetunit) //Use your equivalent of this
local real diff = RAbsBJ(f1-angle) //or RMaxBJ(f1,angle)-RMinBJ(f1,angle)
local real tolerance = 30. //How far it can be from exact facing

    return diff <= tolerance or diff >= (360 - tolerance)

Well, maybe add some tolerance, because you would have to let him face really precisely to have a "true".

JASS:

local unit facer = GetSpellTargetUnit()
local unit faced = GetTriggerUnit()
local real angle = bj_RADTODEG * Atan2(GetUnitY(faced) - GetUnitY(facer), GetUnitX(faced) - GetUnitX(facer))
local real tolerance = 30.00 
if (angle < 0) then
    set angle = angle + 360.00
endif                      
return RAbsBJ(angle - GetUnitFacing(facer)) < tolerance

vile	lol blu, perfect.. what would i do without ya :D
