I've been looking at starfield code and I copied some of it and have been fiddling with it for a while and when I try to reuse objects I get some weird behavior. Could someone tell me where I'm going wrong here? The code LOOKS the same as the code I based it off of with just a few tweaks, but I'm getting "lines" of stars instead of a starFIELD.
