particle engine in a gani?

I know how to put a light effect in a gani,
but is it possible to put in particle engine code into a gani?
I have particle engine code, but just not sure how it would interpret to gani code.

Wouldn't it be pointless? You could make sprites appear to be emitting something by hand :P

Sure, if you miss the point or want it to act in a way that the particle engine doesn't allow.

I'm bored, I'll do it.

I get it alright, but it'd look more..organic so to speak.

It doesn't look like anyone's answered you, so..
Yes you can.

For anyone who wants to know how:
At the bottom of the gani, type

HTML Code:

SCRIPT



SCRIPTEND

Between the SCRIPT and SCRIPTEND, place the particle script.

Yes put the code into a gani script, if you do a gani for a projectile (shoot command) then you can retrieve the angle by reading player.angle

it works wonderfully! thanks!

This is kind of related, but how does Script work in Ganis? I'm trying to make spell that uses lighting effects.

.Open in wordpad
.Type "SCRIPT"
.<insert script here>
.Type "SCRIPTEND"

Thanks. I'll experiment with it later :)

Stefan asking me for something?
Ok yes I am happy to post a screenshot!

Me on the left with the particle engine eminating smoke in a modified idle.gani,
the fire on the right shows the same smoke script with different variables.
The smoke image the first frame of the old smokeani.gif / smokeani.mng
The level here and ganis are on Sanstrata Classic (in development)

Also, here in America it's Thanksgiving, so thank you Stefan for Graal,
it has been great fun the past five years that I have been playing and devloping with thee program, and I hope to enjoy it for many years to come.

Thanks for developing and improving playerworlds and such :D

Hmmm the particles-in-ganis might be interesting for effects like player-on-fire and foot-steps (in snow, water, grass) may be? The foot-steps in the water could be even animated

Good way to ruin an idea for Kingdoms. :(

How is that ruining an idea?

I had been using a gani with a particle effect in a projectile.
However, the particles didn't follow the projectile's z. Is this a bug?
Can anyone check this out for me?

Admins

11-28-2005 02:44 PM

You have set the z value of the showimg/findimg ?

Yen	11-29-2005 10:39 PM

Yes, I tried updating the z with findimg. It still emitted at 0.

I have just recently tried using a particle effect in a gani where the player moves, and I have found that the x and y of the gani stay where the player was and do not follow the player. How do I get the particle effect to stay with the gani and the player? A timeout loop kills the particles, and setting the x and y in the gani makes no difference, please help.

Yen/prozac: what is the script that you have used? Remember that you must do "z = playerz"

There is also the new option "attachtoowner" to let the showimg+emitter automatically follow the player/npc/projectile

Yen	12-13-2005 05:58 AM

:) 'attachtoowner' fixed it, thanks!

Yes, Thank you again Stefan, here is the code that I put with a text editor after the ANIEND at the end of the file.
It makes little concentric circles around, or following, the player.

PHP Code:


		
			
SCRIPT

//#CLIENTSIDE

function onCreated() {

  with (findimg(200)) {

  x=playerx;

  y=playery;

  z=playerz;

  attachtoowner = true;

  attachoffset = {0,0,0};

    layer = 2;

    emitter.continueafterdestroy=true; // looks much better!  thank you!

    emitter.delaymin = 0.05;

    emitter.delaymax = 0.1;

    emitter.nrofparticles = 180;

    emitter.particle.lifetime = 1;

    emitter.particle.image = "icemateria.gif"; //or whatever image you like

    emitter.particle.mode = 1;

    emitter.particle.alpha = .4;

    emitter.particle.red = 1;

    emitter.particle.green = 1;

    emitter.particle.blue = 1;

    emitter.particle.zoom = .5;

    emitter.particle.angle = pi / 2;

    emitter.particle.spin=2.18;

    emitter.particle.speed = 5;

    emitter.addlocalmodifier("once", 0, 0, "angle", "add", -5,5);

    emitter.addlocalmodifier("range", 0, 1, "alpha", "replace",.4, .01);

    emitter.addlocalmodifier("range", 0, 1, "zoom", "replace",.5, .01);

  }

}

SCRIPTEND

However, even if I modify the x and y to be the player's x+1.5 and playery+1.5, that makes no difrence. the center of the emitter is still at the player's x and y.

Either you remove the attachoffset = line (it will use the current difference to the player position then), or you set attachoffset to a good value. So either this

PHP Code:


		
			
with (findimg(200)) {

  x = playerx + 1.5;

  y = playery + 1.5;

  z = playerz;

  attachtoowner = true;

}

or this

PHP Code:


		
			
with (findimg(200)) {

  attachtoowner = true;

  attachoffset = {1.5,1.5,0}; 

}

The second is the preferred method.
