What do you think of my particle?

Looking for some feedback on my particle I recently finished. Looks a lot better in the actual level than in the video. If you'd like to see it you can go to Testbed and warp to "bad.nw".

I think it would look better if you used particletypes and set specific colors (I.e: Red, Green, Blue, Yellow) instead of relying on "random" to generate a color.

PHP Code:


		
			
// Often generates odd/mainly white colors

red = random(0,1);

green = random(0,1);

blue = random(0,1);

I believe it would work something like this:

PHP Code:


		
			
with (findimg(200)) {

  temp.colorz = {

    {1, 0, 0},

    {0, 1, 0},

    {0, 0, 1},

    {1, 1, 0}

  };

  emitter.particletypes = temp.colorz.size();

  for (temp.i = 0; temp.i < emitter.particletypes; temp.i++) {

     emitter.particle[temp.i].red = temp.colorz[temp.i][0];

     emitter.particle[temp.i].green = temp.colorz[temp.i][1];

     emitter.particle[temp.i].blue = temp.colorz[temp.i][2];

  }

}

I'm sure you can apply this to other particle ideas as well. Nice work none the less.

What exactly is 'particletypes'? I understand the colors and it produces some really nice colors that mine didn't, but also what that does is create a big white orb in the middle and then for some reason changes the angles of which they are shot out at.

Also, what are the 3 variables for in 'this.colorz' on each line?

rgb?

Well by default there's only 1 particle type, setting it to 4 allows you have to your particle emitter emit 4 different types of particles.

The only difference is that you would have to use particle[index] instead of just particle.

Post your code so we can try and debug the white orb.

The array of colorz just stores multiple red, green, and blue values. I.e:

PHP Code:


		
			
temp.colorz = {

  {red, green, blue},

};

Ah, I assumed that was it.

PHP Code:


		
			
function onPlayerChats()
{
  if (player.account = "pig132")
  {
    if (player.chat = "/d")
    {
      destroy();
    }
  }
}
//#CLIENTSIDE
function onPlayerEnters()
{
with (findimg(1)) {
  
  temp.colors = {
  {0, 0, 1},
  {0, 1, 0},
  {0, 1, 0},
  {0, 1, 0}
  };
  
  layer = 2;
  emitter.delaymin = 0.01;
  emitter.delaymax = 0.01;
  emitter.nrofparticles = 1;

  emitter.particle.lifetime = 6;
  emitter.particle.image = "g4_particle_sun.png";
  emitter.particle.mode = 0;
  emitter.particle.alpha = 1;
  emitter.particle.zoom = 1;
  
  emitter.particletypes = temp.colors.size();
  
  for (temp.i = 0; temp.i < emitter.particletypes; temp.i++)
  {
    emitter.particle[temp.i].red = temp.colors[temp.i][0];
    emitter.particle[temp.i].green = temp.colors[temp.i][1];
    emitter.particle[temp.i].blue = temp.colors[temp.i][2];
    sleep(0.05);
  }
  
  emitter.particle.red = 0;
  emitter.particle.green = 0;
  emitter.particle.blue = 0;

  emitter.particle.angle = pi / 2;
  emitter.particle.speed = 4;
  
  emitter.addlocalmodifier("once", 0, 0, "angle", "add", 30, 30);
  emitter.addemitmodifier("impulse", .115, .115, "angle", "add", degtorad(45), degtorad(45)); 
  
  emitter.addlocalmodifier("range", 2, 4, "alpha", "replace", 0.99, 0);
  emitter.addlocalmodifier("range", 2, 4, "zoom", "add", 1, 3);
  }
}

Try..

PHP Code:


		
			
function onPlayerEnters()

{

with (findimg(1)) {

  

  temp.colors = {

  {0, 0, 1},

  {0, 1, 0},

  {0, 1, 0},

  {0, 1, 0}

  };

  

  layer = 2;

  emitter.delaymin = 0.05;

  emitter.delaymax = 0.05;

  emitter.nrofparticles = 1;

  

  emitter.particletypes = temp.colors.size();

  

  for (temp.i = 0; temp.i < emitter.particletypes; temp.i++)

  {

    emitter.particle[temp.i].red = temp.colors[temp.i][0];

    emitter.particle[temp.i].green = temp.colors[temp.i][1];

    emitter.particle[temp.i].blue = temp.colors[temp.i][2];

    emitter.particle[temp.i].angle = pi / 2;

    emitter.particle[temp.i].speed = 4;

    emitter.particle[temp.i].lifetime = 6;

    emitter.particle[temp.i].image = "g4_particle_sun.png";

    emitter.particle[temp.i].mode = 0;

    emitter.particle[temp.i].alpha = 1;

    emitter.particle[temp.i].zoom = 1;

    //sleep(0.05); // not even needed...

  }

  

  emitter.addlocalmodifier("once", 0, 0, "angle", "add", 30, 30);

  emitter.addemitmodifier("impulse", .115, .115, "angle", "add", degtorad(45), degtorad(45)); 

  

  emitter.addlocalmodifier("range", 2, 4, "alpha", "replace", 0.99, 0);

  emitter.addlocalmodifier("range", 2, 4, "zoom", "add", 1, 3);

  }

}

Cool, thank you. That removed the odd white orb, but for some reason its like it is skipping certain parts where it should be emitting. Like in the video, it emits in a complete circle. I'm not sure why though. It also seems to be changing the time between emits for some reason...All of those settings haven't been changed

Looks like a pretty cool effect, neat work :)

That kind of stuff can heavily depend on emitter.maxparticles. Can't see it in your code, and I'm not even sure if it has a default value, but try setting that to something higher.

I always thought that if you didn't specify how many max particles, it just didn't have a max. Also, I set it to 100, and immediately it started skipping.

To be honest, I never tried it. I don't know what the default behavior is, it was just an assumption.

Because your delay is set to 0.05 and your particle lifetime is 6 seconds.

You would need at least a maximum of 120 (6/0.05) particles to keep a steady stream.

How to calc it:
emitter.maxparticles = (particle.lifetime / particle.delaymin) * emitter.nrofparticles

Well yeah, I even messed with the delaymin and max, lifetime, etc but still for some reason skips.
