Creating Controllable but non-movable unit

[Eaglefang]

I talked about this already, but I didn't explain this well. So, this is kinda a repost:
Stopping Player-Unit Orders

I need to explain this better, I need a unit that can cast abilities on a unit, but he can't manually move the unit. I have tried alliance aspects (Not with JASS yet) and the order function where it detects "smart" is a start, but that rises the problem of the ability casting not working.

Well, the title says non-movable, but its description says otherwise.

From reading your other post, have you tried giving that unit the "Select Unit" ability in the object editor?

That was a typo
