Virtual Welding

Hey, I am trying to re-create my favourite hobby, ARC Welding.
I am wondering how I could create the "sparks" that fly off though.
Here is the basics of my script so far.

PHP Code:


		
			
//#CLIENTSIDE
function onCreated() {
  hideimgs(200, 500000);
  this.indexn = 200;
  onTimeout();
}

function onMouseDown(var) {
  if (var == "left") {
    this.mode = "on";
  }
}

function onMouseUp(var) {
  if (var == "left") {
    this.mode = "off";
  }
}

function onTimeout() {
  if (this.mode == "on") {
    this.indexn += 1;
    showimg(this.indexn, "g4_particle_sun.png", mousex - 2, mousey - 2);
    findimg(this.indexn).zoom = random(0.2, 0.3);
    findimg(this.indexn).red = 1;
    findimg(this.indexn).green = 1;
    findimg(this.indexn).blue = 1;
  }
  settimer(0.05);
}

Maybe some kind of particle emmiter would do the job.

Use a light particle, zoom it down and when you execute your welding action, make them fly off at random speeds in random directions.

That's so weird. I first read it and thought, "What the hell is he playing at now..."

Lol. Strange.

Does anyone happen to know how to make an image fly off at a random direction?
maybe something like this?

PHP Code:


		
			
this.angle = random(0, 6.4);
this.x -= sin(this.angle)*1;
this.y -= cos(this.angle)*1;

Why don't you try it and see if it works?

When I was getting used to making particle effects, I used ziro's particle editor for quick effects. The effect you're trying to achieve can easily be composed using the editor. Have a look here.

@cbk1994 I can't test it because I am at work.
@Emera Thanks for the link il be sure to check It out.

I have now made the particle effect but how can I make it emit and stop emitting on command?
I have tried a few things but can't seem to get it to work.
Here is how it's set up.

PHP Code:


		
			
with(findimg(200)){ 
  //Stuff.
    with(emitter){
    //More stuff.
      with(particle[0]){
      //Even more stuff.
      }
   }
}

You can control the emitter's behavior by setting emitter.emitautomatically to true or false.
