[1.7.2][SOLVED]Send Packet to Server

Recommended Posts

Good evening everybody,

 

I send the packet to the server but nothing changes.

 

Key event

 

 

	Item[] items = new Item[]{RedTools.redSword, RedTools.redSwordCharged, RedTools.redPickaxe, RedTools.redPickaxeCharged, RedTools.redAxe, RedTools.redAxeCharged};
	RedstoneTools.packetLine.registerPacket(PacketSwitch.class);

	if(invert.isPressed()){
		InventoryPlayer inventory = Minecraft.getMinecraft().thePlayer.inventory;
		for(int i = 0; i < items.length && inventory.getCurrentItem() != null; i += 2){
			if(inventory.getCurrentItem().getUnlocalizedName().equals(new ItemStack(items[i]).getUnlocalizedName())){
				RedstoneTools.packetLine.sendToServer(new PacketSwitch());
			}
			else if(inventory.getCurrentItem().getUnlocalizedName().equals(new ItemStack(items[i + 1]).getUnlocalizedName())){
				RedstoneTools.packetLine.sendToServer(new PacketSwitch());
			}
		}
	}

 

 

 

Packet

}

A good new week everybody.

So I changed it, but nothing changes.

 

Packet

 

 

public class PacketSwitch extends AbstractPacket{

ItemStack itemStack;

public PacketSwitch(ItemStack itemStack){
	this.itemStack = itemStack;
}

@Override
public void encodeInto(ChannelHandlerContext ctx, ByteBuf buffer) {
	ByteBufUtils.writeItemStack(buffer, itemStack);
}

@Override
public void decodeInto(ChannelHandlerContext ctx, ByteBuf buffer) {
	itemStack = ByteBufUtils.readItemStack(buffer);
}

@Override
public void handleClientSide(EntityPlayer player) {

	itemStack.setItemDamage(player.inventory.getCurrentItem().getItemDamage());

	player.inventory.setInventorySlotContents(player.inventory.currentItem, itemStack);

}

@Override
public void handleServerSide(EntityPlayer player) {

	itemStack.setItemDamage(player.inventory.getCurrentItem().getItemDamage());

	player.inventory.setInventorySlotContents(player.inventory.currentItem, itemStack);

}

}

Only the construtor work.

 

 

 

public class PacketSwitch extends AbstractPacket{

ItemStack itemStack;

public PacketSwitch(ItemStack itemStack){
	this.itemStack = itemStack;
	System.out.println(RedModInfo.ModName + ": new Packet");
}

@Override
public void encodeInto(ChannelHandlerContext ctx, ByteBuf buffer) {
	ByteBufUtils.writeItemStack(buffer, itemStack);
	System.out.println(RedModInfo.ModName + ": Packet was encoded");
}

@Override
public void decodeInto(ChannelHandlerContext ctx, ByteBuf buffer) {
	itemStack = ByteBufUtils.readItemStack(buffer);
	System.out.println(RedModInfo.ModName + ": Packet was decoded");
}

@Override
public void handleClientSide(EntityPlayer player) {

}

@Override
public void handleServerSide(EntityPlayer player) {

	itemStack.setItemDamage(player.inventory.getCurrentItem().getItemDamage());

	player.inventory.setInventorySlotContents(player.inventory.currentItem, itemStack);

	System.out.println(RedModInfo.ModName + ": Item was switched");
}

}

Did you register your packet in the PacketPipeline class? If you don't register your packets, it can't process them.

 

I do it in tandem with the initialization process:

public void initialise() {
this.channels = NetworkRegistry.INSTANCE.newChannel(ModInfo.CHANNEL, this);
registerPackets();
}

public void registerPackets() {
registerPacket(SomePacket.class);
registerPacket(SomeOtherPacket.class);
}

Also don't forget to call postInitialise() during post initialization.

 

@Chibill - I have never had any problems with my packets getting sent in the normal client mode, nor in the regular Minecraft launcher; you must be doing something incorrectly.
