I am attempting to make a spell called "Multi Shockwave".
It is meant to send shockwaves casted by dummy units out from the caster's origin,
towards different angles, in a formation something like this:
At level 1, it launches 2, so to be logical and to make the spell look "good",
the shockwaves should be the East-South-South, and the West-South-South.
(The one's closest to the South apart from the middle one).
Level 2 launches 3, so its formation should be the 3 closest to South.
Level 3 launches 4, the formation would be too hard to explain in words.
Level 4 launches 5, the formation would/should look exactly like the diagram.
Basically I need to have the formation of shockwaves more or less "centered",
and evenly-spread about the angle from the caster to the target location.
In saying this, if the angle between the caster and the target location was 90 dgrs,
I wouldn't want one shockwave shooting out towards 20 dgrs, and another shooting out 160 dgrs.
Here is my current JASS code for the spell:
Want to know if it works?
Well, it does!
But not the way I desire it to.
As is, it evenly spreads the shockwaves from the angle given, but the formation of them
isn't the same if I cast at say 50 dgrs and 150 dgrs, or any angle to be exact.
For example, if I cast at roughly 180 dgrs, the shockwaves are widely spread. If I cast at roughly 0 dgrs, the shockwaves aren't spread at all.
This is because the angle between the points is used for the formula;
the closer its value is to 0, the smaller the space between each shockwave.
I could use an If-then-else statement to do this whole thing,
but that would be messy, and I am determined to get a formula working here.
If anyone would like to help me solve this problem, I'd be glad to hear from you.
