Lightning Blast Spell

[Nethrezim]

I want to make a spell that sends out lightning in a line from the caster towards a target location. Lightning arcs like the ones from Chain Lightning spells.



There should be 5 main arcs branching from the caster. The lightning doesn't have to hit the targets like Chain Lightning does, it can pass through them, the damage is important.

What spells should I use as a base and as dummies? If someone could make a triggered template that would be great. In the mean time I'm going to try to figure it out myself. My spell-making knowledge pretty much resumes to this: http://world-editor-tutorials.thehelper.net/cat_usersubmit.php?view=92873

Thanks in advance

You could create 5 dummy units to cast chain lightning. Each one would cast to the target point with a little offset to create the effect you want. Then you would have to run a trigger when the ability is cast to pick every unit that would be damaged and damage them. It would be a bit tedious to make the triggers, so if you are having trouble, I could try making them.

 

[Nethrezim]

Hmm I'm just wondering how do you trigger the dummies to cast lightning at a certain point. And make the lightning bolt jagged at the same time.

 

[Nherwyziant]

I already have this spell, but I can't give you the triggers, since my computer is dead, my spell is very awesome and doesn't need any dummies or stuffs, just the triggers and it's vJass which is awesomer ^_^ and by the way, You can't cast chain lightning at a point, it's a unit target spell.

 

[Nethrezim]

Yeah that's what I was talking about. Anyway I don't want vJass I want it triggered only. So about the chain lightning I can't just cast it on a unit from each dummy because who knows where the lightning will arc. Any suggestions?

 

[Carnerox]

Vjass would be the best for it, unless you want some leaky GUI code.

I used to be more of a GUI person, but it's pretty limited when it comes to removing leaks and MUI/MPI. I still do not know much about JASS, but it just seems to be more natural. But that's off-topic.

You could have the dummies offset from the hero so that the lightning flashes from different points :?

 

[Nethrezim]

@ Undead.Cow: what do you eat vJass with?

@ mylemonblue: I'm not really sure whether I can calculate the offsets to be in line with the target location.

 

[Ayanami]

This spell can be easily done in GUI actually. You just need to use lightning effects and offsets.

 

[Nethrezim]

Ok but what spell should I use as a base? And how do I link the lightning effects to go in a line towards the target location?

 

[Ayanami]

Well you could use channel as the base ability. Basically, move the lightning periodically. This would make it seem as if the lightning is extending outwards.

 

[mylemonblue]

Theory: Have the lightning be a dummy model with permament immolation and a base model of the missile "Storm Seer/BronzeDrake/etc". Then have a trigger move it every .55 seconds to the locations and then..... Um.... Never mind...

 

[Nethrezim]

Here's what I got visually.



The Code



Haven't added the expiration timer yet to study the effects better. Now, as you can see no matter where I target the spell the first 6 arcs branch out up, not towards the target or where the caster was facing. Any idea to trigger it to branch out where the caster is facing? Or towards the target?

 

[Ayanami]

Calculate the distance between the caster location and the target point. Then, set an offset = offset of LocOffset by distance between caster loc and target point towards angle between caster loc and target point. Put this action inside the loop.

 

[Nethrezim]

This is what I get now.



Kind of a reverse effect.

 

[Ayanami]

For your first lightning trigger, target should be LocOffset. For your second lightning trigger, source should be LocOffset and target should be AngOffset.

 

[Nethrezim]

Same problem... the arcs still go upwards no matter where the target is.

 

[Nethrezim]

Sorry to double post, but BUMP! I really want to finish this ability faster

Can anybody tell me how to get the effect I want? And also how do I make the lightning disappear after 0.50 - 1.00 seconds? I tried generic unit timer and countdown timer and they didn't work.

The Arcs obviously goes upwards because you set a value of 0.00 for your real. You'll need to do this.

• Actions
  • Set Real = ((Facing of Caster) - 90)
  • For each (Integer A) from 1 to 6, do (Actions)
    • Loop - Actions
      • Set LocOffset = (CasLoc offser by 200.00 towards Real degrees)
      • Lightning - Create a Chain Lightning - Primary lightning effect from source CasLoc to target LocOffset
      • Lightning - Create a Chain Lightning - Primary lightning effect from source LocOffset to target AngOffset
      • Set Real = (Real + 36.00)

As for your expiration question, does this spell need to be MUI?

 

[Nethrezim]

Well I don't know anything else besides triggering.

EDIT: And thanks, visually works fine now.
