ok i have a problem i made a magna guard and put him in a map. But when i use his jump attack he attacks than bounces up and down until i respawn or get killed.

Heh, I had that several times due to a near-overload of the memory pools. Bump up your melee-related memory pools 5 - 10 times. If there's still a problem, post your combo file.

whats a melee memory pool?

Look at the stock Mos Eisley hero assault lua.
