On line 34, instead of doing

Code:java

for(Player pl : Bukkit.getServer().getOnlinePlayers())

do

Code:java

Player[] onlineplayers = Bukkit.getServer().getOnlinePlayers();
for(Player pl : onlineplayers)

 

Theres no diff Gerov

W8 sorry Gerov ure right if you do it your way you might get ConcurrentModificationException

 

bump

 

Jamscott

Have you read Gerov 's post?

 

The Bukkit developer team changed the returned object of getOnlinePlayers() from a Player array to a Player Collection. Use the same version you used to build your plugin on your server, or update both to use Collection: Collection#toArray(T[])

 

ZodiacTheories I fixed it i was using bukkit but when i changed to craftbukkit it was fixed
