This probably wasn't diffictult to make.If there's velocity up or down, it will fire.If there's no velocity up or down, it won't fire.Or, if the character isn't touching any bricks.
Okay, same link as above, ought to do the same damage as normal rocket and only work in the air.Oh, and it's maroon.
It's still a hassle. Lugnut is one of the most useful and productive people on the forums, so don't dis that.EDIT: I've been wanting a no-damage rocket launcher for a while, and you said you had one. Is there any chance of me having it?
