I noticed the links no longer work and I found it somewhere and I thought somebody else would need it. This is the best R4CCE out that I know of. It lags somewhat but it works fine. Depends on your computer in all honesty.
Or when your player dies, you can say in code, if enemy exists, do nothing, but if enemy does not exist, then create enemy at certain spot. (This would be a pain tho for lots of emeies)
