[Trigger] Help need for spell

[Quetzalcotl]

Hello everybody, I'm in need for some help for a spell I tried to make but didn't work out.

So it should spawn 3 fireballs, launch them in 3 different directions (based on the facing of the hero) and should explode on unit impact.

So far it only spawned the units who then disappeared after a second.

Thanks in advance, and I hope there is someone that can fix it.

Have you initialized the hashtable?

You don't have to save thge handle of last created unit, just set BSPRojectile = Picked Unit in the loop trigger.

You could loop the projectile creation, to reduce the amount of lines of code.

You do

• Set BSProjectileLocation = (Position of BSProjectile)

in both THEN and ELSE branch, so move it to before the IF/THEN/ELSE. Also move that location removal.

I'll try that, thanks already.

EDIT: Cheers it works now, I totally forgot about actually making the hashtable because I copied the trigger from my other map.
