Well, I have a nice little dash spell. With the whole fading dummy behind the caster as he's dashing deal. Now, everything works absolutely perfectly... except that the dummy is slightly offset from the caster. Here are some stats about my dummy:
- Flying unit
- No movement type
- No collision size
- Locusted
- Invulnerable
I don't know what causes him to stand at an offset. I even tried spawning him somewhere else and moving him to the correct location with SetUnitX/Y. Nothing's working.

Yes, yes, I know. The real variable names I use for the polar projection are horrendous.
