Halp :3

 

@SergeantBud You need to put return true between line 50 and 51. If not, it's continuing the expression (therefore, if the args.length == 0, it will still try and get args[0] which doesn't exist.

 

@SergeantBud

Also, good luck with those ConcurrentModficiationExceptions. You shouldn't access ArrayLists from multiple threads, either use the correct event (PlayerChatEvent) or use a thread safe Collection (like CopyOnWriteArrayList).

Thanks!

-*- CODE REMOVED SO IT ISN'T STOLEN -*-

New code: But when I type a argument in game an internal error occurs? Help please?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

you wrote args[01] on line 54

 

I know I tried args[0], args [01], args [1], and I still got internal errors so I just kept guessing. What do I do instead of that?

 

args[0] should work. Read this: http://bukkit.org/threads/32457/. If you still can't fix it post your errorlog.

 

Thanks!
I see my error now.
However; now there is no console error, yet there is a error.
Either something around

Code:

-*- CODE REMOVED SO IT ISN'T STOLEN -*-

is wrong or something around

Code:

-*- CODE REMOVED SO IT ISN'T STOLEN -*-

is wrong. It works 90%, it just doesn't change the chat color. Help?

 

@SergeantBud your mistake is at if(args.length == 0)
it should be args.length == 1

EDIT: IGNORE this made a mistake myself :/

 

... How is that a mistake ?

 

Did you register the events?

@Protophite
array.length returns the amount of objects in it
array[k] returns the object at k place. It begins with 0

 

@SergeantBud yeah my bad I didn't read it correctly.

You didn't register your events.

 

@FisheyLP Ah yes! Thanks it works now !
*DELETING CODE SO IT CAN NOT BE STOLEN*

 

Sorry but your code can be easily remade and is a little bit useless xD
