What's up with the creepy ass music щ(ﾟДﾟщ)?

Your program crashes sometimes. That's because the "living" ArrayList is being accessed from 2 different threads at the same time. A simple fix for this is to replace all occurences of this line in MoveEngine.java

for (int i = 0; i < Main.living.size(); i++) {

with

int size = Main.living.size();

for (int i = 0; i < size; i++) {

But that's not a very nice solution. Why did you use different threads in the first place? That's not necessary.

Could you link me to a tutorial on how to make the equations for changing the x and y value of the ball? I'm trying to make a simple 1-ball gravity simulator but I don't know how to write the correct equations or how to do the collision detection.

i did a similar program but when i put a lot of balls the pressure makes them over lape each other, how did u fix that

@Hectorfloresish Check out the project's homepage on sourceforge, and scroll down to the "Resolving collisions" section. The link is in the video description!

Awesome, could you please upload the source somewhere so we can view it?

[OneRadVideo]

I think I will put the source up somewhere, but I want to get some other things cleaned up about the code first.

Thanks, It will be much appreciated.
