Flying Height, Jumping Question

Okay so I made a jumping ability using triggers (no JASS) that launches you x range from your current position depending on which way your facing, it works fine, except I originally had the hero with flying movement but 0 height so he couldnt go over walls or through trees or any of that, but after he lands since I didn't use a dummy unit for it hes now able to move as though he were flying even though he has 0 flying height. Any help would be appreciated.

Flying movement automatically makes you be able to walk through walls anyways. It doesnt matter what your flying height is I'm afraid :/

Ahh your right, I looked at Hans_MaulWurfs jump ability and figured out how he was able to do it.

Ok, here's a way that you can change the flying height of a unit and leave its movement type as ground or whatever. It's rather simple...All it requires is a dummy spell...take metamorphesis and set it so the alternate form is a flying unit(doesn't matter what one), and then in your triggers(somewhere), add the spell to the unit that you want to change the height of and then remove it...and then for some reason it will allow u to change the units height as if it was a flying unit. ^_^
Hope this helps...if so think you could give a little rep?
