#2 does NOT do the same thing as #1, even with no flags specified. #1 is guaranteed to loop through every index up to MaxPlayers. Whereas #2 will only loop through all indexes that are occupied in the server.
Say you only have 5 users connected and 32 slots max.
#1 will loop through 32 times
#2 will loop through 5 times
I do not browse the forums regularly anymore. If you need me for anything (asking questions or anything else), then PM me (be descriptive in your PM, message containing only a link to a thread will be ignored).
