I'm making Impetus from dota, a spell where a projectile is thrown and after the target unit is hit, it takes a certain % of the distance the projectile covered in damage. I can do all of this just fine, although, I have run into a strange problem when I want to damage the target unit. If I use the UnitDamageTarget action, the game exits as soon as the projectile hits the target (as soon as it takes the damage).
The spell is auto-castable, which means the projectiles should fire whenever the spell is under auto-castable effects, but, at the moment, I'm still trying to get the "EVENT_UNIT_SPELL_EFFECT" side of things working. Afterwards, I'll add in more to the trigger which makes the auto-casting stuff work.
Here is my current code (WIP):
So there it is, my problem lies in the Impetus_Actions_3 function.
Everything works 100% perfect apart from the UnitDamageTarget line.
I know it's that line because after removing it, then testing the spell it doesn't exit the game/crash/malfunction.
What could be the problem here?
