WoWMathHelper.GetPointAt() what is rotation and pitch?

[strix]

Like in topic name, what exactly is rotation and pitch in this function?

I basically need to calculate points at side of boss and slightly behind (the way you fight dragon bosses with melees).

Would it be something like WoWMathHelper.GetPointAt(unit.Location, unit.InteractRange, unit.Rotation, Math.PI / 1.8)?

Basically it calculates from + dir * distance, where "dir" is a unit vector similar to the following:

Notice the red arrow - that is the vector.

If you need to calculate points at sides of units, there is WoWMathHelper.CalculatePointAtSide. If you want to roll it yourself, you can cross a Z-vector (0, 0, 1) with the 2-D facing vector of the unit (cos(yaw), sin(yaw), 0).
