[code snippet] Recommending a server texture pack

EDIT: Bukkit now has an api for this. Player.setTexturePack("url");

I know others have done it, but in lack of many resources on the subject, I thought I would explain how to change a client's texture pack.

Code:java

 
public Packet250CustomPayload getTexturePackChangePacket(String url) {
 
Packet250CustomPayload packet = new Packet250CustomPayload();
 
int size = 16;
String message = url + "\u0000" + size; //build the data
 
byte[] data= message.getBytes();
 
packet.data = data;
packet.length = data.length;
packet.lowPriority = false;
packet.tag = "MC|TPack"; //set the channel
 
return packet;
 
}
 

This just uses the custom payload packet to recommend a texture pack to a client. There are other uses to the custom payload packet (if I find a really cool use for it, I will write another tutorial). This packet takes a channel, and some data. In this case, the channel must be MC|TPack, and the data the link to the texture pack. To use this, link craftbukkit.jar to your project, and sue the following to send the packet:

Code:java

 
EntityPlayer victim = ((CraftPlayer) p).getHandle();
victim.netServerHandler.sendPacket(getTexturePackChangePacket(url + p.getWorld().getName() + ".zip"));
 

You can keep changing the pack too. iZone allows custom texture packs based on regions, as an example. Anyway, I hope somebody can make use of this.

 

You need a client mod, correct?

 

Incorrect, this is part of vanilla minecraft 1.3
