I'm trying to make a minigame I already mentioned in other questions of mine. I think I got all the commands except one. I need a command block to return true when there is only one player left and that'll end the game.
I haven't tried anything yet because I have no idea how to do this. I have also tried researching this but I never get any info. Also, I'm on 1.7.10.
Is this possible in 1.7.10 and if so, how do I do it?
