Weather System

[coreys]

I have yet to see any decent weather system around Graal, so, after I found some old weather effects I made using the particle system, I decided to make my own and release it.

Main WNPC:

PHP Code:

  temp.check = false;
  for (temp.lvl: this.levelstarts) {
    if (player.level.starts(temp.lvl))
      temp.check = true;
  }
  if (player.level in this.levels) temp.check = true;
  
  if (temp.check) {
    //Make sure the weather gani is correct
    if (player.attr[this.attr] != this.weather)
      player.attr[this.attr] = this.weather;
    client.weather = this.weather;

      this.timer++;
    else { //It's time to change weather
      this.timer = 0;
      temp.change = random(0,this.chance[1]);
      if (temp.change > this.chance[0]) //If the weather changes
        this.weather = randomstring(this.types);
      else this.weather = ""; //Or returns to normal
    }
  }
  else { //Turns weather off if your level doesn't allow it
    player.attr[this.attr] = "";
    client.weather = "";
  }
  setTimer(1);
}
//If the weather gani ends the weather manually
function onActionEndWeather(acc) {
  if (player.account == acc)
    this.timer = this.maxtime;
} 


This weather system uses gani's to show weather effects. It's completely clientside, so not every player is going to be experiencing the same weather. I may make a serverwide weather system sometime in the future. The gani is set to a player.attr[], which you can change in the script. I think I've commented it fairly well, so anything you want to change should be easy to figure out.

Here's the gani for the rain effect that I am releasing. It uses the particle engine, as I would suggest everyone use for any weather effects they want to make.

And attached I have a rain particle GFX.

Enjoy!
