JASS Shapes

[Hadeis]

Hey, i was looking aroung The Hive, but I didnt find a tutorial for creating shapse and dynamic effects with JASS (circles, spirals, etc). If anybody could give me some tutorial or script for those, id give big thanks.

This is the best for static shapes:

It is for GUI, but the functions are essentially the same. It is just the math.

If that doesn't help I might be able to whip up a few samples, what shapes do you need?

that kind of stuff is usually done by moving dummyunits which have the model of the desired effects. Moving the units is done by teleporting them periodically (setting their position using a periodic timer with like 0.03 seconds timeout).

To form the shape you just need to find an expression for the x,y,z values (or x(t), y(t), z(t) functions). This requires some basic math knowledge, but nothing difficult.

Example for a circle with radius r u just use x(t) = r * cos(t), y(t) = r * sin(t), to change the angular velocity multiply the argument of sin and cos with a factor.

To make a spiral use the same expressions and add z(t) = t * v_z with v_z being the speed in z direction. Looks like this:

Yeah, right...

Thank you guys, and Purgeandfire, could you post maybe something like line or shockwave in JASS?
Thanks anyways +rep for you.

globals
	//counts the steps
	integer i
	//x,y of start position
	real xStart
	real yStart
	//x,y of each step
	real xD
	real yD
	//the dummy
	unit dummyUnit
endglobals

function move takes nothing returns nothing
	if i < 100 then
		set i = i + 1
		call SetUnitX(dummyUnit, xStart + xD * i)
		call SetUnitY(dummyUnit, yStart + yD * i)
	else
		call DestroyTimer(GetExpiredTimer())
	endif
endfunction

function shockwave real x, real y, real angle returns nothing
	set i = 0
	set xStart = x
	set yStart = y
	set xD = cos(angle)
	set yD = sin(angle)
	call TimerStart(CreateTimer(), true, 0.03, function move)
endfunction

math:
x(t) = xStart + xD * t
y(t) = yStart + yD * t
or with vectors:
(x, y)(t) = (xStart, yStart) + (xD, yD) * t

Big thanks man, really helped me! Thank you!
