Detect a Chain?

Is there a trigger to detect if units that is hit by chain lighting.?? All units i mean.

no,there is not. if you ave basic JASS knoledge, look at vex's caster system.

Is there any place good for learning JASS?

the tutorial repository.

Which spell in it does the chain detect??

I don't detect chain lightning, I actually trigger the whole chain effect that is easier.

You made me note that I forgot to include the chain template in my Spell Factory Map, ouch

I agree, triggering it all is easier.

Daminon made a spell that detects it though: http://www.wc3campaigns.net/showthread.php?t=78980.

Well I could detect chain lightning the other day, but I do preffer making it:
