Stencyl / HaXe : Changing Background using an Actor

Changing Background using Actor

Put an Actor on the scene (with invisible pixels)

Put it on the scene on the 0 layer

Put the tiles on the 1 layer

Put the Player on either layer 2 or layer 1

The background actor needs two animations. The first is the invisible one to start with.

The second is the name that is ‘animation_name2’ refered later in the code.

This animation will be overriden by the code

for each [actor of type] [Select the Background Actor]

Code-block:

  var bitmapData = new BitmapData(1024,1024,false, 0x000000);

  // load the image into the bitmapData or use the following code:

   var i:Int=0;

   var j:Int=0;

  var rc:Int=0;

  var gc:Int=0;

   var bc:Int=0;

  for(i in 1 ... 1020){

      for(j in 1 ... 1020){

   var pixel=i;

   rc=pixel;

   gc=pixel+rc;

   bc=pixel+gc;

  

  bitmapData.setPixel(i,j,(rc<<16|gc<<8|bc));

   }

}

var iti:Array<Int> = new Array<Int>();

iti.push(100); // animation time

var ba:BitmapAnimation = new BitmapAnimation(bitmapData,1,iti,true,null);

// animation_name2 must exist (as a second animation on the Actor)

actorOfType.addAnimation("animation_name2",ba);

actorOfType.originMap.set("animation_name2", new B2Vec2(bitmapData.width/2,bitmapData.height/2));
