How to set players Prefix/Suffix

How do i set players prefix or suffix? (With the groupmanager API) i already tried but this gave me a NPE:

Bukkit.getServer().dispatchCommand(Bukkit.getServer().getConsoleSender(), "manuaddv " + player.getName() + " suffix" + " " + this.gm.getSuffix(player ) + " A 2nd suffix here");

 

@Firerydragon2442 You could just use Vault's API...
http://milkbowl.github.io/VaultAPI/ - Then go to Chat and you'll find the setPlayerSuffix and setPlayerPrefix methods.

 

Well i tried but it seems to give me a NPE

Main.chat.setPlayerSuffix(player, "TestSuffix");

 

@Firerydragon2442 Errors (console errors?) - Is the player null? Is Vault not available so Chat is null? Are you making sure that you're using the .jar file inside the /plugins/ folder when you run the server (and you're using [depend] or [softdepend] to make sure that the API's are there?)

 

Error = nullpointer
How do i check if vault is available
Yes
Yes

 

Would this work?

Code:

@EventHandler
public void onChat(AsyncChatEvent e) {
e.setFormat(yourPrefixHere + " " + e.getPlayer().getName() + " " + yourSuffixHere);
}

Also, you probably got a NPE before because i'm guessing your chat variable inside your Main class was null.

 

im not doing a chat event. Im setting a tag (suffix) from a inventory

 

Then use the tag from the inventory to store the tag in a config, then onChat get the tag from the config?

 

@Firerydragon2442 You can't just say there was a NullPointerException, was there no stacktrace?

 

There was and it said it was a NPE at Main.chat.setPlayerSuffix(player, "TestSuffix");

 

@Firerydragon2442

Then Main, chat, or player may be null. This is why you should actually use encapsulation and not just huruduurrrr static everything.

 

And i can test this to use it in main class? So to make sure Main is not null?

 

@Firerydragon2442

I don't understand what you're saying.

 

okay i tried to use it in main and its still giving a NPE at the chat.setPlayerSuffix ect.

Main:

@Firerydragon2442

"chat" is likely null.

 

here is another way to do it, i think it is much simpler.

Code:

player.setDisplayName(prefex + " " + player.getName() + " " + suffix);

this way works with default chat handlers and some plugin chat handlers.

 

How di i

make it not null?

No >.< players already have a prefix and suffix i only want to add them ....

 

You should do this:

Code:java

e.setFormat(yourPrefix + "%s" + yourSuffix + ": %s"); //Can reset message color if wanted

Where the first %s will be automatically replaced by the player name and the second %s is replaced by the message. It's the syntax for java.util.Formatter (and basically printf or anything of the sort in C), and should be used rather than manually replacing the values yourself.
