Angle Problem

[DonRoman]

Hey^^

I somewhat got a problem with finding the correct angle between 2 points, I took a look at the bj fucntion and saw the Atan2 thing, so I thought i would just do the same and use coordinates.
However somehow i cant get it to work, the angles go from 0° - 90° and then go back to 0°

somewhat like this:


-------- 90°
---- 0° ------- 0°
-------- 90°

heres the code:

private function Orders takes nothing returns boolean
    local unit u      = GetTriggerUnit()
    local real dx
    local real dy
    local Squad squad = Squad<u>
    
    if GetIssuedOrderId() == OrderId(&quot;move&quot;) or GetIssuedOrderId() == OrderId(&quot;patrol&quot;) or GetIssuedOrderId() == OrderId(&quot;smart&quot;) then
        set TempInt = GetIssuedOrderId()
        set TempX = GetOrderPointX()
        set TempY = GetOrderPointY()
        set dx = TempX - GetUnitX(u)
        set dy = TempY - GetUnitY(u)
        set TempAngle = Atan2(dy * dy, dx * dx) // here lies the error i think
        call BJDebugMsg(&quot;Atan2 :&quot; + R2S(bj_RADTODEG * Atan2(dy * dy, dx * dx)))
        //call ForGroup(squad.members, function MoveOrder)
    endif
    set u = null
    return false
endfunction</u>

Its probably just some stupid error made by me ...

function AngleBetweenPoints takes location locA, location locB returns real
    return bj_RADTODEG * Atan2(GetLocationY(locB) - GetLocationY(locA), GetLocationX(locB) - GetLocationX(locA))
endfunction

You're multiplying dy with dy and dx with dx.
You should do this:

set TempAngle = bj_RADTODEG * Atan2(dy - TempY, dx - TempX)

Just use dy and dx

Atan2(dy, dx)

thx guys

I knew it was some stupid mistake .... :/
