Some spellmaking questions

Okay, Well, I got a few questions since I suck at coding, but am apparantly great at ideas and stuff, as I will be uploading my map soon when I get a bunch more items out, and add about 10 more heroes (Total of 30), which will probably leak alot because I have gotten about 3 fatal errors (Does not always happen as I have not pinpointed the cause), and to see how it preforms on other computers (About 20% of people have said it lags, which im thinking might be the spawning system, or the item groups). Almost everybody who has played it says it has huge potential, and is really good, the only complaint was the occasional person who had lag issues.... well, back to the core.

Is there any real difference besides Jass and vJass? Or is vJass something like the caster system by vexorian?.... Heck, I cant even figure out how to use the physics systems and partical systems here, rofl.... I would at least need an example to work with, lol. I can read about 50% of the code, and can usually change to get the effect I want.... Just like I can read japanese given enought time with my chart, but have no idea what im saying, lol.

Well, One of my ideas that I will probably never figure out is this, and I have 2 questions. What would something technological count as?
It would target like forked lightning (Target point if im correct), and would launch an arc of 'bullets' (Probably rockets of some sort) quickly in an arc sweeping to the right, then to the left (Basically going over the arc twice). It would be about a quarter circle from the units current facing out to a range of about 500. The bullets would explode on impact, or when they reach thier target point, or hit a wall...... I would also like the unit to have its attack animation played along with turning, so I guess he bullets could be launched from its facing. I would like the whole thing to happen in about 2 seconds.

Speaking of which, but is there anything that I may use as a reference (As in a projectile system that has the exploding when it hits a unit, or reaches its endpoint? I know pyrogasm made that fireball spell, but it does not explode against trees, or when it reaches its max distance without hitting anything.) Also, If I could get an example of a few physics system spells (As in say a bouncing lazer that reflects off walls or something, and deals damage in a line)

Since this was the only part of your post that was on-topic, I decided to move it out of the spell olympics thread. The answer to this would be: depending on the special effects you use. It could be fire projectiles, it could be ice... just bullets, however, likely won't do. Some spells just don't fit in any category, the goal is to design spells that do.

As for your other questions:
Yes, vJass is better.
Have you tried the caster system?

Yes, I have tried it, but unfortunately I cannot really build anything out of it, only really modify some stuff. The only thing I might be able to build would be simple spells in gui (e.g. Casting a warstomp where a frost nova is cast for example, changing the effects of warstomp so that it uses the freezing breath buff instead of the stun one). But I doubt anything like that would win anything in this contest. For stuff like vjass, jass, and caster system, I can usually change just enough to alter the effect, or less often- being able to alter how its cast (I dont know if taking an idea that I have seen from another spell thats cast where the caster stands, and changing it to work more like a 'target area' would count though)

I tend to be immensly hopeless when really learning these things unless I have a really good chart or something that would list what stuff does along with a snippet of code, where you can just sub the stuff into the area.

Also, sorry for going off toping, I tend to do that.

Jass is equal to Custom Text. It is the scripting language which Warcraft III uses for triggers/scripts (triggers are just masked script).

vJass is an extension to the original jass syntax. vJass is possible because of Vexorian's JASSHelper program, which converts vJass syntax into normal jass.

The Caster System is a system written in vJass, which have a lot of functions for automatically doing a lot of stuff for you. For instance, you can easily make any launch-missile-to-target-and-do-scripted-effect spell with the Caster System.

EDIT
I'm not really sure how you mean that the spell is supposed to be performed... multiple missiles, spreading out, going in an arc, first to the left, then to the right... Could you elaborate, or provide some pictures?

This is a basic picture-


The big black dot is the caster, and the red one is the target point.
Basically when you target the point, the caster turns 45 degrees to the right, and fires 90 degrees to the left (In an arc), then fires back to there the caster origionally startecd firing. In what im thinking, the whole thing would take at most 2.5 seconds. Each arc would take 1 second to fire, and there would be a brief pause before starting the second arc (0.5 seconds). I would also like to know if it would be possible to make another version of this that the rockets would not explode. (I have seen this done just by setting the dummies pathing to zero in maps that use collision systems like in battlemages, but this might just be removing of a line of code in the caster system or whatever is used)
