    }

    //screen.render();

    }

    Graphics g = bs.getDrawGraphics();

    public static void main(String[] args) {

    frame.setVisible(true);

    System.out.println("Running...");

    game.start();
    }

    }

    Render.java

    package com.mime.soilderattack.graphics;

    public class Render {
    public final int width;
    public final int height;
    public final int[] pixels;

    public Render(int width, int height) {
    this.width = width;

    pixels = new int[width = height];
    }

    public void draw(Render render, int xOffset, int yOffset) {
    for (int y = 0; y < render.height; y++) {
    int yPix = y + yOffset;
    for (int x = 0; x < render.width; x++) {
    int xPix = x + xOffset;

    pixels[xPix + yPix * width] = render.pixels[x + y * render.width];
    }
    }

    }
    }

    screen.java


    public class Screen extends Render {
    private Render test;

    public Screen(int width, int height) {
    super(width, height);
    Random random = new Random();
    test = new Render(256, 256);
    for (int i = 0; i <256*256; i++); {
    //test.pixels[i] = random.nextInt();
    }

    }

    public void render() {
    for (int i = 0; i < width * height; i++) {
    pixels[i] = 0;
    }

    for (int i = 0; i < 200; i++) {

    }
    }
    }

    Default Re: codeing help random pixels

    Please Edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    tell me what to do and where to put it
    Can you explain what the problem is? What are you trying to do? What does the program do that you want to change?
    If you don't understand my answer, don't ignore it, ask a question.
