MUI Projectile Trouble

[Tyross]

I had a (very rough) triggered spell[1], which caused the caster to fire a "ki ball" towards the area of the ability which it was based upon. The ball would then be destroyed if it came within 50.00 of any unit, and also deal damage to them. I had this working to a satisfactory level and was about to neaten it up when i stumbled upon a problem;

The variables I use in the triggers do not allow Mulit-Unit-Instancing, I spent the next hour researching MUI, and managed to apply it successfully[2]. However the tutorial read that you may not use the local variable in a "pick every unit" action, which my spell contains;

-Are there any loopholes or techniques I can use to make my spell MUI?

Any help will be greatly appreciated.

[1]Ki Ball Trigger 1

• Events
• Unit - Unit begins casting a spell
• Conditions
• (Abilitiy Being Cast) Equal to Ki Ball (Neutral Hostile)
• Actions
• Unit - Create 1 Ki Ball for (Owner of (Casting unit)) at (Position of (Casting unit)) facing Default building facing degrees
• Set Combatant1KiBall[1] = (Last created unit)

[2] MUI Test - this worked successfully, with 5 footmen being created and destroyed in the correct order and completely.

• Unit - Kill muitest

*PS. I know it leaks; like I said, rough!

Since there are no waits inside the pick every unit and do actions trigger, you can just use globals inside there. If there were waits... well the only way to do it would be massive arrays.

Correct me if im wrong; but the problem im trying to work through in my head is;

If i set Combatant1KiBall[1] a local variable to trigger [1] using the jass script, then trigger [2] will not be able to read that local variable?

But if i make Combatant1KiBall[1] a global variable, then i cannot make the trigger MUI?

GUI MUI Missile System V1.03 - The Hive Workshop - A Warcraft III Modding Site Maybe this helps you.

Besides, you leak.

Use variables, and Jass scripts to clean them up.

(Unit groups, and positions, mostly)

Indeed useful for the making the projectile aspect MUI, however I still cant work out how to make the other aspect trigger [2] MUI?

-Blooddancer, I stated in my first post that it leaks, because i just wanted to get the spell working, I can plug the leaks and make it tidier later.

Well, you can do it on nearly the same way, just get a idea of how my system works.
