    I'm getting an Exception in thread "Thread-2" java.lang.NullPointerException
    at gameJava.framework.SpriteSheet.grabImage(SpriteSheet.java:14)

    Why is this?
    I know it's returning a null input from somewhere but I don't know how to fix it

    this way of doing it is cool and all but not very flexible. You have to have tons of different RGB values in your loadlevel image to keep track of and you can only use a static sky background image for instance, meaning you cant design levels with changing backgrounds. I'd recommend using a tile software to make your level then exporting it and using that image instead of drawing in each block. Youd have to figure out a way to only draw the part of the image that is on the screen though as using huge images is very slow

    So i can run my game good and everything but the only thing is that when i load the image of the player i get the white background that the player has in the SpriteSheet how can I get rid of that and just be able to load the image of the player?

    GUYS: If you want to increase your FPS, this is an easy solution.
    This is the render method of your Block class.
    What it does is only render if the block is inside the screen, otherwise it isn't rendered. this increases FPS by a lot because there is no reason to render things outside the screen… Hope this helps!

    public void render(Graphics g) {
    // Cull blocks outside the screen to increase FPS
    if ((this.x > -Camera.getX() + Game.WIDTH) || (this.x < -Camera.getX() – 32) || (this.y > -Camera.getY() + Game.HEIGHT) || (this.y < -Camera.getY() – 32)) {
    ;
    } else {
    if (type == EnumBlockID.DIRT) {
    g.drawImage(tex.block[0], (int) x, (int) y, null);
    }
    if (type == EnumBlockID.GRASS) {
    g.drawImage(tex.block[1], (int) x, (int) y, null);
    }
    }

    }

    How do you fix the player clipping through the blocks? You said that you were going to fix it at the end of your last video!

    Ok, I would have thought you would explain how to make the textures, because I have no idea how to in terms of sizing and stuff…
