Why are only some of my objects being rendered?
- by BleedObsidian
Every time I create a new asteroid the previous one is no longer rendered?
I did some debugging and printed out the size of Array-List 'Small' and when a new asteroid is created it doesn't go down, so the thread is still there it's just not being rendered, Why?
