Projectile randomly being screwy

[LearningCode]

Yea, there's this spell where the hero creates a projectile and fires it forward.
Kinda' like shockwave, just that it deals damage based on how much "Rage" the caster has.

So, I made it in JASS.

The problem is that the spell frequently travels in the wrong direction or spawn wrongly (Instead of spawning at the caster, the dummy spawns at the caster with a polar offset, which is random, too).

I've tried to alleviate the spawning wrongly by pausing the caster -Failed-

Meh, here's the code, it's killing me to figure this out -___-

         local CF cf = CF.data

->

         local CF cf = this

 

[LearningCode]

Do I do that for all my methods? (Except for the .allocate() one)

 

[kingkingyyk3]

nonono.
Change the one in periodic method only.

 

[LearningCode]

Okay, gonna' try it out now =x

[EDIT]
It worked O_O
So..
Tell me..

Why did it work after that minor change? o.0
