Impossible Trigger? HELP

ok i know there have been many threads concerning jumping triggers in here. and i followed the instructions to the letter.
i used a dummy spell, and it replaces the unit with a flying unit, changing its height. the problem is that when the jump is over i cant replace the unit back to its original, since the unit that was jumping in the first place was a hero. how am i supposed to replace the temporary flying unit with my original hero?
is that possible?
and if not then how can i work around that?

please help

I dont fully understand the problem. Could you go around it by hiding the hero, and creating the jumping unit, then destroying the jumping unit and unhiding the hero?

Like neenja said, hide the Hero. Instead of removing the caster, just hide him\her. When the dummy unit gets to the end point, instantly move the caster to the point, and then unhide him\her.

ok ill try that thank you

You can also try replacing your hero with the metamorphosis spell, have the alternate unit have the same stats and abilities, the only difference being flying.When the timer runs out, the unit becomes your original hero again.

That wont make him "Jump" that will just make a unit look like its flying. If you use storm crow form it will work. Just make a trigger saying when a unit uses storm crow make unit use the alternate form. That will make the unit look like its jumping and its a rather simple trigger. Sorry i didnt eleborate on the spell and the trigger but you should understand...i think.

ahh yea these suggestions are all good and well but... try this (not exact but itll do)

Events: unit casts spell

Conditions: Spell is Jump
