Hi, I want to create a score for my game. The problem is that I have an actor crosshair with the code to kill the targets, but I need the number, how many targets are getting shot, in the MyWorld class to display it as I want. How can I get access to that number? Thanks in advance.

Use the following to get the World object:

MyWorld world = (MyWorld)getWorld();

Because 'world' is of type MyWorld, you can access any public fields or methods in the MyWorld class. For example, you can follow the line with:

world.score++;

if the 'int score' field was public; or, you could have a public method:

public void bumpScore()
{
    score++;
    updateScoreDisplay(); // or code to update the display of the score
}

in the MyWorld class and use:

world.bumpScore();

after getting the MyWorld reference in 'world' above.

Ok, thank you. It works well. But how could I display it now, because it is int and not a String?

You should probably check out my Value Display Tutorial scenario. If you cannot view that, it can also be found here
