Lightning target prolems (no JASS)

I'm working on a spell, it's based on fan of knives. Now the problem is when I wanna attatch the lightning to the target. I want it to go from the caster to the target. But Creater lightning from casting unit to target of spell being cast won't work. The best solution I have found is to make it hit a random unit within 600 of the casting unit, but that is unrelyable. Can someone plees help me?

Help? In what way, what's the problem, exactly?

Fan of Knives is an area of effect spell, it doesn't have a target, thus the "target unit of ability being cast" event response gives you no unit. How is random unit unreliable?

Well I want the lighning to target every unit that gets damaged, and random won't do that.

then just take ALL units in the range of the hero, not just 1...

One idea that comes to mind is an untargeted dummy spell in place of the fan of knives. Then create a dummy on top of the caster, and have it use an appropriately modified forked lightning at a random unit - which will then make it hit surrounding units as well.

I'm not sure how well that'll work (if at all), just throwing out an idea.

Uhm, I made a similar thing in oneof my spells. Just create a unit group matching some conditions (f.e. enemy units and so on) and save it in a variable (i.e. called "Lighters"). Then make a func "for each intenger from x to y do..." (where x and y are the spell's "caps"); in the loop do the following: pick a random unit from Lighters, save it in a variable called "Light", apply the lightning to Light and then remove this unit from the group (in this way a unit cannot be targeted more than 1 time). I hope this can help u...
