Uninterruptable abilities

[Klasus]

How do I make abilities uninterruptable? what I mean is that when you cast the ability the unit shouldn't be able to do anything for 0.5 sec, not even cancel the ability. Right now I have to have the cast time to 0 sec because otherwise it screws up with the trigger events.

Check how the Battlecruiser does it. Once yammato cannon is locked I do not think you can stop it.
