Particle effects

[Raeiphon]

Help?

I've tried over and over to get particle emitters to work - the wiki documentation is nice, but not what i'm looking for. I learn best off working examples and I have no idea where to find any. I'm trying to create an emitter/effect that makes the player trail a little (Zodiac has a similar) effect. Could anyone assist me here? Code snippets, advice, where to start, anything is welcome.

Attached to that thread is a tutorial written by TGC and an emitters demo scripted by Stefan.

Finding examples is simple, check your levels/ganis folder, particle effects are often stored in gani script.

Thanks for the assistance, but now I have another problem:

I want every player in the level to see said particle effects. The particle effect in mind would radiate over my player. The only way I can think of doing this is by gani scripting and showani, but I have no experience with either.

Help?

Here a script I found somewhere long ago, helped me learn alot from particles and how they work.

Yup, you gotta use gani script

Any basic examples on how to get an emitter to work inside a gani, and how to display that gani through showani?

If you're attaching the gani to the player, use an attribute. Example:

player.attr[4] = "sword.gani";

You'd mainly use attributes if you were wanting something to follow a player that other people could also see. Let's say a light- or an aura; for example.

showani(index, this.x, this.y, direction, gani, params);
showani(300, this.x, this.y, 2, "sword", NULL);
showani(1, this.x, this.y, 2, "sword", NULL);

As you can see, it's clientside and also serverside! You can modify this also, like so

with(findimg(index))
{
  //and ok
}

Not too sure why you'd decide to use this over the player.attr, maybe if you wanted to display something that wasn't connected to the player, yet interacted with the player in some way?

Gani scripting is generally used when you're wanting something to show for everyone, such as an effect. You'd most-likely use gani script in combination with the player.attr command.
Inside the gani, you'd insert something like this:

SCRIPT
function onPlayerEnters()
{
  with(findimg(200))
  {
    //doParticle effects
  }
  setTimer(0.05);
}
function onTimeout()
{
  findimg(200).# = ##;
  setTimer(0.05);
}
SCRIPTEND

As you can see, you can also pretty much add anything inside of the gani. You can't edit this locally, the NPC-server would read the script from the gani inside the servers FTP.
You'd now need to know more about particles, I suggest opening a few Graal Kingdoms spell effects, they're mostly particles and they help you to understand how they work. [They're the gani's, 'g2k2_spell#']
