ViaMCP-Reborn
Repository to keep up with ViaVersion on MCP (Originally from https://github.com/LaVache-FR/ViaMCP)
1.7.x Protocols
Yes, i know they are not working right now, do not make a pull request to remove them, as i am not going to remove them.
Small note about version
If you are using 1.8.x as a client base, use viamcp src folder
If you are using 1.12.2 as a client base, use viamcp1_12 src folder and rename it to viamcp
Installation
You will need to add some lines of code before you can use ViaMCP
You also need to add libraries into dependencies before using this!
Main Class
Add this to the main class of your client (aka injection function)
try
{
ViaMCP.getInstance().start();
}
catch (Exception e)
{
e.printStackTrace();
}
NetworkManager
You will need to replace 2 functions in NetworkManager.java
1: (Name may vary, but should be func_181124_a or contain (Bootstrap)((Bootstrap)((Bootstrap)(new Bootstrap()).group((EventLoopGroup)lazyloadbase.getValue()))
Add:
if (p_initChannel_1_ instanceof SocketChannel && ViaMCP.getInstance().getVersion() != ViaMCP.PROTOCOL_VERSION)
{
UserConnection user = new UserConnectionImpl(p_initChannel_1_, true);
new ProtocolPipelineImpl(user);
p_initChannel_1_.pipeline().addBefore("encoder", CommonTransformer.HANDLER_ENCODER_NAME, new VREncodeHandler(user)).addBefore("decoder", CommonTransformer.HANDLER_DECODER_NAME, new VRDecodeHandler(user));
}
After:
p_initChannel_1_.pipeline().addLast((String)"timeout", (ChannelHandler)(new ReadTimeoutHandler(30))).addLast((String)"splitter", (ChannelHandler)(new MessageDeserializer2())).addLast((String)"decoder", (ChannelHandler)(new MessageDeserializer(EnumPacketDirection.CLIENTBOUND))).addLast((String)"prepender", (ChannelHandler)(new MessageSerializer2())).addLast((String)"encoder", (ChannelHandler)(new MessageSerializer(EnumPacketDirection.SERVERBOUND))).addLast((String)"packet_handler", (ChannelHandler)networkmanager);
2: setCompressionTreshold (Yes, minecraft devs cannot spell 'Threshold')
Comment out: (Old Decoder)
this.channel.pipeline().addBefore("decoder", "decompress", new NettyCompressionDecoder(treshold));
Replace with: (New Decoder)
NettyUtil.decodeEncodePlacement(channel.pipeline(), "decoder", "decompress", new NettyCompressionDecoder(treshold));
Comment out: (Old Encoder)
this.channel.pipeline().addBefore("encoder", "compress", new NettyCompressionEncoder(treshold))
Replace with: (New Encoder)
NettyUtil.decodeEncodePlacement(channel.pipeline(), "encoder", "compress", new NettyCompressionEncoder(treshold));
GuiMainMenu
You will need to add a button to access the protocol switcher
In addSingleplayerMultiplayerButtons() function you will need to add the following code:
this.buttonList.add(new GuiButton(69, 5, 5, 90, 20, "Protocol"));
In actionPerformed(GuiButton button) function you will need to add the following code:
if (button.id == 69)
{
this.mc.displayGuiScreen(new GuiProtocolSelector(this));
}
Finishing
You should now be able to use ViaMCP
If you have any problems, DM Hideri#9003 on discord!
