Use a boolean field to indicate mouse being over that area or not (or indicating background state): <Code Omitted>

idk i think i forgot to remove it ... but thank you. i think i ll leave it without high score, it is not so important, but still thank you very much

The code for adding 1 about every second seems alright. There are close to 60 act cycles a second when the speed is set to 50 = the middle (and there is no lag of course). Depending on what is happening instead of what it should, it might be clever to not have the counter and the timerStopped variable static or initialize them when creating a new Mülltrennung world.

Thank you, still, a beginner in coding will definitely double-check the brackets from now on!

Line1 and Line2 are not players and should not extend the Player class. Player1Wins and Player2Wins are not Player1 and Player2 type objects and should not extend those classes. Create a generic Line class extending Actor and have both Line1 and Line2 extend it and create a generic Win class extending Actor and have both Player1Wins and Player2Wins extend it. If you want to associate a particular player with the different lines and win objects, then put each of those specific classes in

Move line 7 to before line 4 (or at least before line 6). So set the background before you remove the actors. The actor which is executing the code (the ship) is removed from the world in line 6. After that, you can’t try to set the background of the world which is returned by getWorld() because that is null (the object isn’t in any world since you just removed it from the world). Alternatively, you can get the reference to the world before removing it:

Oh wow, I was quickly going over the code and saw all that moving and turning that I instantly thought it had to be an Actor subclass..

thank you it worked

If you mean your world should be just a 3x3 grid you could just adjust this in the World-class: <Code Omitted> This means that your world is consisting of 3x3 cells, every cell is 200x200 pixels (so the width of your world actually is 600px - 3 cells a 200 px).. You can set your marks with something like <Code Omitted> This sets a mark into the middle cell, as you start counting cells with 0: 0/0 1/0 2/0 1/0 1/1 1

Use a boolean flag. Initialize it before, test while inside (changing its value if random is 1) and check its value after the while loop to do whatever when 1 hits.

now I need to make a score counter I have this so far. I don't know what else to do.

A simple breakdown of pong ball boundary codes would be like: <Code Omitted>

I solved the problem! I changed something in the counter class and it dident work anymore, so i copy and pasted everything in to a new scenario and it worked! But thank you for your response!

Add an act method to your World subclass (MyWorld) and go to end when no crabs are in world.
