any help?

 

@TheFl4me
One word: 'Check'

You need to add a check before trying to get an index that might not exist.
This line:

Code:

        String tagother = ChatColor.GREEN + "Success! " + args[1] + " now looks like a ";

is the problem.

This could be that the args[1] isnt being entered
in other words

/<command> <arg0> <arg1> <arg2> etc ...

If args[1] isnt entered then it really doesnt exist.

Add a check by doing ..

Code:java

 
if (args.length() >= 2) {
    // then is valid..
} else {
    // They havent entered correct arguments
    sender.sendMessage("Please enter in the correct format");
 
}

 

Thanks i simply moved the String under the
if(args.length == 2) {

 

@TheFl4me
Yeah you do and no problem
( remember to tahg person you want to speak to so they receive an alert )

For example if i had a command for /givemojangpowers <player> <power>
You would want to check for the last argument (<power>) exists before trying to get information from it

If this solved your problem be sure to set the thread prefix to [solved]

Leave a like if i helped!

 

I did it on purpose so they dont recieve an alert :P (i have my crazy reasons)

Srry for the reopening of the thread but im having another problem with the same classes.

in 1.7.10 Everytime a player would join it woul automatically set his displayname and tabname to the colors of his rank.
but ever since i updated to 1.8 the displayname works but not the tabname

I have to do the /tag cmd to fix this.

Joinevent code:

Code:

@EventHandler
    public void onPlayerJoin(PlayerJoinEvent e) {
        Player p = e.getPlayer();
        TagListener.TagDefault(p);

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

@TheFl4me How are you setting the tab name? Just use Player#setPlayerListName(String name)

 

that is exactly what i am doing, look in the classes above.

 

@TheFl4me Oh yeah sorry.

 

bump

 

anyone?

 

come on pls
