@TrippyHD https://jd.bukkit.org/org/bukkit/Server.html#getOnlinePlayers()

 

@TrippyHD
getOnlinePlayers returns a collection. Collection have a method called "size()" which returns how many objects are in the collection.

 

Assuming you're trying to get how many players are on the server. Use .size not .length

Damn you beat me to it lmao @Zombie_Striker

 

Bukkit changed what that method returns. If you are 1.7.9 (version may be wrong) or below, it returns an array. Now it returns a Collection.

 

Thanks for your help, I forgot this I haven't coded in a while
