I think it was mentioned on this forum and/or on Blitzcoder (for instance by Morduun who was trying to write a new "random" function) that the random number functions, using the same seed, for some reason do not always return the same values on different computers. Depending on what you do with those numbers this might explain why the enemies do not move the same on different computers.
Really? I always thought something was iffy about it, i still need to check my code to make sure I don't use it for anything "important". I use it mostly for explosion particles, backgrounds, the stuff that does not matter gameplay wise. There could be something in there. Thanks
