It's my first pretty complex JASS spell. Comment and rate

All the IDs, special effect paths, damages, distances, etc should be configurables at the top of the map script.

Immolation · May 14, 2009

Updated.

v1.1
-Improved code and documentation.

wraithseeker · May 14, 2009

You don't need those angle converting and the way you are adding your effect can be simplified to this.

JASS:


call DestroyEffect(AddSpecialEffect()) // fill in the stuffs you need!

Immolation · May 14, 2009

What do you mean by "angle converting"?

BlackRose · May 14, 2009

JASS:

        if BLADE_DISPEL == true then
            call KillUnit(GetCenterUnit())
            else

- You don't need else to do nothing.
- Just do if BLADE_DISPEL then

- WTF? How far do you knock enemies back? 5 seconds? 900 distance?
- Sorry but, effects are, dissapoint me for a water spell

It is simple, boom and go in slide.

Romek · May 14, 2009

It is possible to have configurable functions you know, not only variables.
Damage, distance, etc should all be config. functions.

Also, you leak a few locations which aren't destroyed - only nulled.

I'll take a look at this (as well as most of the other resources) in more detail once my exams are over.
