[JASS] Properly using XYZ?

[Coolty44]

Hey, so after trying to break off my "relationship" with the PolarProjectionBJ stuff.

I've been wondering, how do I properly set up a XYZ system that gets the X and Y offset from the caster's point, and then make a proper circle?

I've tryed several functions, but none of the seem to do the job right. It's propbably really easy, call me a noob if you must, but it isnt working that well for me right now.....

Sin()/Cos() are your friends for Y/X coordinates. I suggest you take a close look at trigonometric functions.

They're your friends also in 3d, it's just harder to see it.

function PolarProjectionBJ takes location source, real dist, real angle returns location
    local real x = GetLocationX(source) + dist * Cos(angle * bj_DEGTORAD)
    local real y = GetLocationY(source) + dist * Sin(angle * bj_DEGTORAD)
    return Location(x, y)
endfunction

Thats how you do polar projection.

Also, as for setting a units height properly, use this.

Thanks, that seems to be working better now, thanks guys. Now I'm having trouble with using the X Y to create lightning. NewGen ok's it everytime, but the lightning never apears.. Why is this?

Can we see your script? Perhaps you created the lightning but did not enable it.

Ok, I'll pot it. I've probably made a mistake somewere, and I havnt patched all the leaks yet, I had to rename a few things

Script

EDIT: After being able to look at it on the site, I've reliased I was using the effects instead of the lightning's when I created it.
