images in p2d

kellen

So I'm making a game and it is starting to get very laggy. I switched the renderer to P2D and the frame rate has doubled so that's good. The only problem is that now I can't see the image I was using for a background, and the points I was using as stars are very hard to see.

Can you show a small example / program version of the background problem?

PImage sky;

void setup(){  
  size(1080,720,P2D);
  colorMode(HSB);
  sky = createImage(width,height,HSB);
  for(int y = 0; y < sky.height; y++){ 
    for(int x = 0; x < sky.width; x++){
      sky.set(x,y,color(255,0,0));  
    }
  }
}

void draw(){
  image(sky,0,0);
}

PImage sky;

void setup() {  
  size(800, 600);
  noLoop();

  colorMode(HSB);
  final color c = color(255, 255, 127);

  sky = createImage(width, height, ARGB);
  java.util.Arrays.fill(sky.pixels, c);
  sky.updatePixels();
}

void draw() {
  background(sky);
}
