This is a script that cycles through a series of textures.

My only problem is that is goes really fast.

Is there any way to change the speed?

// @input Asset.Material sprite

// @input Asset.Texture[] textures

 

var currentItemIndex = 0;

var count = 0;

 

script.sprite.mainPass.baseTex = script.textures[currentItemIndex]

 

var event = script.createEvent("UpdateEvent");

event.bind(function (eventData){

if (count == 0) {

currentItemIndex += 1;

currentItemIndex = currentItemIndex % script.textures.length;

script.sprite.mainPass.baseTex = script.textures[currentItemIndex];

}

});

  Hi, Lauren

  Try this :

  // @input Asset.Material spriteMat
  // @input int framesPerSecond = 10
  // @input Asset.Texture[] textures
   
  var currentItemIndex = 0;
  var count = 0;
  
  var delta = 1.0/script.framesPerSecond;
  var time = 0;
   
  var pass = script.spriteMat.mainPass;
  pass.baseTex = script.textures[currentItemIndex]
   
  var event = script.createEvent("UpdateEvent");
  event.bind(function (eventData){
      if (time >= delta) {
          currentItemIndex = (currentItemIndex + 1) % script.textures.length
          currentItemIndex = currentItemIndex % script.textures.length;
          pass.baseTex = script.textures[currentItemIndex];
          time = 0;
      } else {
          time += eventData.getDeltaTime();
      }
  });

  Best
