Attacking Multiple Enemys

[UnLimiTeD]

Ok, just say, im a noob in triggering, i don't know anything from jass.. now i want to make a spell(or in this case, a trigger) that allows my unit to fire many shots on different enemys in short time. Rigth, in SHORT time, not instant.
As an exsample, think of an automatically aiming rocket magazine.
But in the Moment i just don't get it to fire missiles 1 by 1, but all together.... bored of this nonworking stuff, i deleted the whole trigger, and now I would like U, yes, U, to help me with this problem.

You can add/remove ability of the siege engine, or create many dummy-attackers at the position of casting unit.

Or when the unit starts casting the ability just add phoenix fire to that unit. Just modify the range, the missile and the countdown. Then wait till you want your unit to attack multiple targets and remove the phoenix fire ability form the casting unit.
