Java bot for an online game

Question

I am creating a bot in java using the java.awt.Robot. The bot works fine on a browser (I have also tested it using Microsoft Word!) but when I run it in the game, the only function that works is the mouseMove. I want to build a bot that simply presses keyboard buttons for me.

I instantiate the robot class

Robot r = new Robot();

Then I do some simple stuff: press z,press 1, move the mouse and right click.

r.keyPress(KeyEvent.VK_Z);
r.keyRelease(KeyEvent.VK_Z);

r.keyPress(KeyEvent.VK_1);
System.out.println("Press 1 button");
r.keyRelease(KeyEvent.VK_1);
System.out.println("Release 1 button");
r.delay(1000);

System.out.println("Move mouse");
r.mouseMove(110, 690);

System.out.println("Press");
r.mousePress(InputEvent.BUTTON3_MASK);
System.out.println("Release");
r.mouseRelease(InputEvent.BUTTON3_MASK);

Why is this happening? Can this Robot class perform these kind of actions within a game if it runs in the background?

Thank you

Update: If I run my bot on PES 2012 for example, it works fine but if I run it on an online game like Cabal, it does not work? the protection system of the game does not detect anything so that is not the case.

Answer 1

First of all, most games have bot protection, so make sure to add a delay to the bot and, maybe, a 'cooldown'. Before that r.delay(1000) statement, the bot did two instant actions.

I'm almost sure it's not working because the keystrokes are way too fast: they press and release instantly. Try adding bot.delay(500) (or more, depends on the game) right after you instantiate Robot class; before all the key pressing functions. That would add a 500ms delay between ALL actions done by the robot.

public static void doStuff() {

    Robot r = new Robot();

        r.delay(500); //Or more - depends on the game

        r.keyPress(KeyEvent.VK_Z);
        r.keyRelease(KeyEvent.VK_Z);

        r.keyPress(KeyEvent.VK_1);
        System.out.println("Press 1 button");
        r.keyRelease(KeyEvent.VK_1);
        System.out.println("Release 1 button");
        r.delay(1000);

        System.out.println("Move mouse");
        r.mouseMove(110, 690);

        System.out.println("Press");
        r.mousePress(InputEvent.BUTTON3_MASK);
        System.out.println("Release");
        r.mouseRelease(InputEvent.BUTTON3_MASK);
}

I think the only reason why the Z and 1 keys didn't work was the speed everything was done. The game probably has an anti-bot system.
