Easily change the name of a player! (event the name above the head :P)

Heyho Community,

I made this, because I think a simple and good lib/class would be cool.
So @FTWin01Gurl wanted to make a library, so you can take this and make one
It was fun to create it and only took 5 mins so yeah do with it what you want
Never tested it, so simply contact me if something isnt working.

p000ison

 

I am confused, do I start with this then do the tutorial...
OR
Do I copy this then add to the code so I is how I want it?

Also there do I put in what is in the example?

 

Pls Change mad into made !
And nice tutorial

 

Its a whole class. So copy it into your project and do for example: DisplayNameChanger.changeDisplayName(player, name);

k, done

If you like the class please give me an internet

 

Where do I put the DisplayNameChanger...?
Do you mean I put that anywhere I want there?

Also where do I put for example:

Code:

public void onEnable(){
            this.getCommand("blue").setExecutor(new TeamExecutor(this));
            this.getCommand("red").setExecutor(new TeamExecutor(this));
            this.getCommand("leave").setExecutor(new TeamExecutor(this));
}

Or is this totally seperate?

Sorry for begin difficult

 

Another mistake

Changes the titel of a player above his head

Tiel , Change To Title

And I wanna ask you if you can add This Method To The Code

changing the players 's name back after he has executed a command .

 

hm can not find "Tiel " lol

So you mean a reset method?
If yes give me 2 mins xD

fixed a typo and added reset methods

You can put it where you want to change the name

??

 

I think he meant that you spelled "title" wrong

 

I said it wrong previously
It Should Be This.

titel => Change To Title


EDIT : Thanks For Reset Methods
READ THIS !!!
EDIT EDIT : I notice All Your Title Has Been Spelled to titel

 

Ye i will change it tomorrow xD In Germany its spelled like this so yeah xDD Almost the same

 

You need to substring the username if it's 15 or 16 characters long as 16 is the maximum amount of characters for a players 'title' (name above head) and tab list name which means when you add the color to their name and it's that long you get super fun exceptions in console.

 

You do know that replacing & with the unicode thing is bad? If i were to nick myself "Delocaz&", it will crash all clients, according to the wiki.

 

Still wrong
But nice tutorial, you can also do a similar (more hacky thing) and change the actual player, so they get a different inventory etc etc.

 

Ah ye, Ill update it soon Have a better idea than this

Found some minutes to write a new and better one. Simply call updateJoin when a player joins.

p000ison

 

Added as optional

 

p000ison EntityPlayer? I guess I am meant to be adding something that I haven't?

 

You need craftbukkit as a library so you include the net.minecraft stuff

 

I added the craftbukkit jar, Still error and I cant import EntityPlayer and CraftPlayer doesn't exist.

 

remove the 2 imports from above and import them again

 

Now I only get error on
((CraftPlayer)playersonline).getHandle().netServerHandler.sendPacket(new Packet20NamedEntitySpawn(changingName));

 

It's playerConnection now (after 1.4.6).

In any case, why not use TagAPI instead?

 

I heard that your players have to download a file or something like that, And I would much rather do it myself and learn.

Oh and Thanks for that I got it working! Only in events for some reason

 

They will have to download and install TagAPI, sure, but a lot of servers are already running it. It's not that big of a hurdle.

But it's not just a matter of convenience. TagAPI ensures that your plugin is compatible with every other plugin that also modifies the displayed name of a player (list here). p000ison's library is not compatible in these cases.

 

I would recommend the TagAPI, too. I think the time I wrote this there was no tagapi

 

I see what you guys are saying but my server will only really include a max of 5 plugins, my custom coded one, bPermissions, Votifier, BuyCraft and maybe worldedit/voxelsniper when needed.
