Sort of off topic. Rogue formula

Does anyone know how to calculate the x,y position behind a target using it's current Orientation/Rotation.

I'm not that great with math, yes even simple High School math like this.

I appreciate any/all help.

Didn't test it, but this should work:

float tmpX = Math.Cos(Unit.Facing + (Math.PI / 2)) * 3; 
float tmpY = Math.Sin(Unit.Facing + (Math.PI / 2)) * 3;

int behindX = Unit.X - tempX;
int behindY = Unit.Y - tempY;

That sort of works, it takes me to the left corner that's ALMOST behind it. I guess I need to figure out which direction the mob is facing to get directly behind it?

Thanks for the response

A player's position + his facing gives you a 2 dimensional vector, that's all you need.

v = (target_x, target_y) + s * (cos(target_facing + pi/2), sin(target_facing + pi/2))

Now you can just set s to -1 if you want to behind the target, or an even smaller number to be further behind.

Might have ****ed up somewhere but that should give you an idea.

Meh I did indeed. You'll have to adjust it to WoWs coord. system:

      /\ x
       |
<----|-----y

so in wows system it should be: v = (target_x, target_y) + s * (cos(target_facing), sin(target_facing))
as it's system is rotated by pi/2 to the common coord. system.

Hope it's right now ~~ brb suicide

That works great, thanks both of you for responding. I would give rep if I could.
