I'm on snapshot 15w41b by the way.
So I set up a bunch of teams that I'm using as ranks in vanilla Minecraft, and then set up a row of command blocks that use the
/testfor command that have comparators running from them to another command block that has the
/scoreboard join command.
So it's like this: command block with
/testfor @p[lm=30,l=49], and then a comparator running from it to another command block with
/scoreboard teams join (team) @p[lm=30,l=49]. It works perfectly but only for one player; for some reason it won't add two players to the same team when they reach level 30. I also tried different selectors like
(player name) but they didn't work any better.
Any help would be appreciated thanks!
