Pillar of Lightning

This spell channels forces of chaotic nature, conjuring a large pillar out of the ground, which randomly fires off lightning bolts at nearby enemies. Each lightning bolt deals 100 damage.

For the sake of an intelligible post, I will use spoiler tags. (Yes, I know. Deal with it.)

The effects looks nice.. i would think of using a Finger of death effect ray but it's nice anyway.. i will look to the code later

 

[worldofDeath]

Is this level able or just one level?

 

[Sim]

I just... love that one spell

Good job, approved!

> Is this level able or just one level?

You can change the level of the chain lightning in the object editor, as well as the damage.

 

[Ghan]

> Is this level able or just one level?

Sure. Just add more levels to both the hero ability and dummy unit ability.

> Good job, approved!

Really? Already? That's unexpected. I thought you'd love to shoot my code down for a while.

 

[Jimpy]

Tad off topic, but for someone with 5000+ posts, and like 900+ rep... This is your first spell submitted?

 

[Ghan]

> This is your first spell submitted?

Yes. It is.
Usually can't come up with a feasible idea or don't want to take the time.
I did create a spell for the Spell Contest III, though.

However, the idea for this spell actually came from a completely different idea that didn't work as expected....

 

[Jimpy]

Awesome.

Spell looks cool, I'll check it out and comment on scripting tomorrow.. I suppose though if I give it 'approval', it doesn't mean much.

 

[waaaks!]

cool spell...its better to make the lightning's color to purple...

 

[Ghan]

> cool spell...its better to make the lightning's color to purple...

Methinks that would require a model editor, right?
I don't do model editing.
Or pratically anything to do with art.

 

[waaaks!]

well i think there are already made models out there

or use the lightning trigger and change the tinting color of the lightning

wait! i dont mean to push u make that...i just want to suggest

 

[Tinki3]

Cool spell

Doesn't "Set TempPoint = ((Target point of ability being cast) offset by (0.00, 0.00))" leak the way it is?

Why is that variable set that way?

 

[U are a noob]

Please post the code. Some people don't always want WE open.

 

[Tinki3]

>Please post the code. Some people don't always want WE open

Agreed.

Also, no implementation notes were included in the map.

The 'ReadMe Template' was untouched

 

[Ghan]

> Why is that variable set that way?

Because in debugging, I thought that the Target Point of Ability being Cast might be getting lost in the same way that All Players won't work if you set a variable to it and destroy it, so I made the point unique.
It may not make any difference.

> The 'ReadMe Template' was untouched

For now.

 

[Naminator]

Great Spell!

Like the effect. Good job Ghan!

 

[Ghan]

Thanks for all the positive comments.

I updated the spell. Added more variables to give the user easier control over the spell, and also added implementation instructions.

GUI is too simplistic If you do things the right way, it works, heh.

No!! I want you to shoot my code down!

Fine. Have it your way. JASS version posted.

Locals under the names of globals?

Why?
