    my camera is inverted. pls help

    nevermind i fix it. i forget the "-" on the "player".

    my mistake was: x = player.getX() + Game.WIDTH/2;

    and i fix it to: x = -player.getX() + Game.WIDTH/2;

    How do you get the camera to stop at x=0, x=the width of the game, and the same for y, so that you can't see beyond the stage?

    Guys: If you wanna have a Y coord in the camera class, change the x and y variables to int and just cast for the player coords. If you use floating point integers (float) for the Y coordinates, it'll start shaking and being wonky.

    I think it'd be more efficient if the player was not in the handler's list of objects and was rendered separately.

    In the previous video you said you would explain how to fix the sticky key problem of the character sometimes stopping moving.

    Could you explain this please?

    if you want the smooth camera:
    float xTarg = -player.getX() + Game.WIDTH/2;

    x += (xTarg – x) * (Number between 0 and 1)

    Tip for eclipse users. Hold alt+shift + s and than select generate getters and setters. Makes life easier.

    For everyone whos camera is way faster than the player make sure u delete the line in ur "game" class.
    ////////////////////////////////////////
    g2d.translate(cam.getX(), cam.getY()); <———— DELETE THIS!!!!!!!!!

     //DRAW HERE

    g.setColor(Color.black);
    g.fillRect(0, 0, getWidth(), getHeight());

    g2d.translate(cam.getX(), cam.getY()); //begin of cam

    handler.render(g);

    g2d.translate(cam.getX(), cam.getY()); // end of cam
     /////////////////////////////////////////

    You should be writing the minus marks in Class Game render() -method this way:

    g2d.translate(-camera.getX(), -camera.getY()); //begin of camera
    handler.render(g);
    g2d.translate(camera.getX(), camera.getY()); //end of camera

    not:

    g2d.translate(camera.getX(), camera.getY()); //begin of camera
    handler.render(g);
    g2d.translate(-camera.getX(), -camera.getY()); //end of camera

    it's then easier to control the camera's tick() -method: 
    x = player.getX() – Game.WIDTH/2;

    Wouldn't it be better to pass the camera instance to the handler's tick method and check if the object is a player in the loop that ticks all the objects?

    Also, I think it's "tweening", not tweAning 😉

    Last video you said to show smooth movement in this case. When a "movement button" is pressed really fast. It stops moving, and then continues just as thinking a while. But I never saw you to show, Please can you show it?

    The translate method in Graphics2D solves an issue I've been having for a couple of days – thanks.

    Christ sake i did this and At the start the game is half the screen and the other half is the game but you cant control it.. If you start moving to the right you fix it but than the blocks on the bottom start getting messed up.. whelp.. is there something wrong with my x = -player.getX() + Game.WIDTH/2;
