Hi,

 

Im making an sketch with many balls moving. Each ball is an object, and there are always new balls borning. I have an array list of balls, and move them with a for loop, but I want balls always borning and balls dying. If I only change balls parameters for not display them, the array list would be too big, and I don´t know how to delete an object and remove it from the array list.

 

Thank you
