So my friends and I play on a server via hamachi, and I want to set it so that when they join the game we can’t see each other’s player IDs and health. Per this thread: http://forum.facepunch.com/showthread.php?t=1202446 I copied that code into a lua file and placed it in lua/autorun/server. However when I started up the server I got an error about how it attempted to call GM, which is a nil value. No idea what this means as I have no experience with LUA, though my gut instinct is there should be a pretty simple fix.
Any help would be greatly appreciated, I just want to turn of the player ID/health on aim for me and my friends.
