sorry let me clarify, I found the code from a discussion on how to make barriers it wasn't directly related to cars. Also thank you a lot for helping me, and this code definitely does block the cars. But, I have just found out from playing that when a car gets stuck, and I attempt to turn left or right, my car will end up slowly going through the wall. Do you know why this is happening and how I could fix it?

I have a feeling the signs on the plus and minus 15 in the setLocation statements are backward.

You change the livesCounter value in the livesScore(int add) method. That would be the best place to check if the NEW value is zero (and if so, display game over).

Copy the folder onto your local disk and extract it if it is a zip.

Your for loops are set to iterate twice the length of the array. Meaning, you are creating more Track objects than the array can hold. That is, your array length is 68880 and you try to place 137760 Track objects in that array. It can't be done. Hence the error once your loop counter reaches 68880, since the last element is indexed at 68879.

Thank you @danpost, its working better now. :)

Thanks man, you carry this site

Thanks so much, I used 1 health for each player and used a switch and it cleaned up my code (and performance) by sooo much

Actually, never mind I managed to fix it, thanks alot for your help @danpost

Thank you

Try to remove the brick from the ball class and remove all code inside the brick class. It’s never good to have intersection checks in the classes of both objects which intersect with each other.

thank you @danpost, that makes sense. Thank you for your help :)

ah alright I will try make some code with this example and then come back to say if it worked just to keep updated

What have you tried? Show attempted codes (which should be in subclass of World)..

alright, i'll check it out. thanks for the help!
