Hello guys I need help with this trigger, this line is causing an error '' Syntax Error, unexpected: ''i''?

for i = 0 to (DamageDetection___index - 1)
if (DamageDetection___spells == abilityId) then
call UnitAddAbility(GetTriggerUnit(), DamageDetection___DETECTION_ID)
return

The return seems to be source of issue, who's DamageDetection is this btw?

I think Mr. Bean create this library for his spell pack, here it is maybe you could take a look at it View attachment super_nova - Gunslinger SP.w3x

I think you are using Vexorian's jasshelper. Switch to Cohadar's if you want for/while loops.

vJASS does not support "for" loops. The code is illegal.

This is the answer.

You have to use JNGP 2.0:

And switch to cohadar's jasshelper to support for loops.
