Hello, I'm trying to extend a 'saber' on a KeyBinding I have the KeyBinding as so only on the ClientSide;

package info.mineverse.willow.sabers.client;

import info.mineverse.willow.sabers.SaberBase;

import java.io.ByteArrayOutputStream;

    {
        //the first value is an array of KeyBindings, the second is whether or not the call 
        //keyDown should repeat as long as the key is down
        super(new KeyBinding[]{saberExtend}, new boolean[]{false});

{

}

@Override
public EnumSet<TickType> ticks()
{
	return EnumSet.of(TickType.CLIENT);
}
}

 

I also have the packet handler as so;

package info.mineverse.willow.sabers;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;

import net.minecraft.src.Entity;
import net.minecraft.src.EntityClientPlayerMP;
import net.minecraft.src.EntityList;
import net.minecraft.src.EntityPlayer;
import net.minecraft.src.EntityPlayerMP;
import net.minecraft.src.EntityPlayerSP;
import net.minecraft.src.INetworkManager;
import net.minecraft.src.ItemStack;
import net.minecraft.src.Packet250CustomPayload;
import cpw.mods.fml.common.FMLCommonHandler;
import cpw.mods.fml.common.Side;
import cpw.mods.fml.common.network.IPacketHandler;
import cpw.mods.fml.common.network.PacketDispatcher;
import cpw.mods.fml.common.network.Player;

public class PacketHandler implements IPacketHandler
{
@Override
public void onPacketData(INetworkManager manager, Packet250CustomPayload packet, Player player)
{
	if (packet.channel.equals("SaberExtend"))
	{
		handlePacket(packet, player);
	}
}

private void handlePacket(Packet250CustomPayload packet, Player player)
{
	DataInputStream inputStream = new DataInputStream(new ByteArrayInputStream(packet.data));

    	int itemID;
    	int itemDamage;
    	int slot;
    	
	try
	{
		itemID = inputStream.readInt();
		itemDamage = inputStream.readInt();
		slot = inputStream.readInt();
	}
	catch (IOException e)
	{
		e.printStackTrace();
		return;
	}

	Side side = FMLCommonHandler.instance().getEffectiveSide();
	if (side == Side.SERVER)
	{
		EntityPlayerMP executingPlayer = (EntityPlayerMP)player;
		executingPlayer.inventory.inventoryChanged = true;
		sendPacket(executingPlayer, itemID, itemDamage, slot);
		closeInventoryChange(executingPlayer);
	}
	else if (side == Side.CLIENT)
	{
		EntityClientPlayerMP executingPlayer = (EntityClientPlayerMP)player;
		executingPlayer.inventory.inventoryChanged = true;
		closeInventoryChange(executingPlayer);
	}
}

private void closeInventoryChange(EntityClientPlayerMP player)
{
	player.inventory.inventoryChanged = false;
}

private void closeInventoryChange(EntityPlayerMP player)
{
	player.inventory.inventoryChanged = false;
}

    private void sendPacket(EntityPlayerMP entityPlayer, int itemID, int itemDamage, int slot)
    {
    	int playerID = entityPlayer.entityId;
    	
    	ByteArrayOutputStream bos = new ByteArrayOutputStream(16);
    	DataOutputStream outputStream = new DataOutputStream(bos);
    	try
    	{
    		outputStream.writeInt(playerID);
    		outputStream.writeInt(itemID);
    		outputStream.writeInt(itemDamage);
    		outputStream.writeInt(slot);
    	}
    	catch (Exception ex)
    	{
    		ex.printStackTrace();
    	}

    	Packet250CustomPayload packet = new Packet250CustomPayload();
    	packet.channel = "SaberExtend";
    	packet.data = bos.toByteArray();
    	packet.length = bos.size();
    	PacketDispatcher.sendPacketToPlayer(packet, (Player)entityPlayer);
    }
}

 

When I press the KeyBinding the item dissappears and comes back quickly and doesn't change. I can't see what's wrong.

Dude, I have pretty much the exact same problem :P.

 

I'm doing my own saber mod, and trying to get the saber to extend on a keypress, but using metadata. The texture won't change tho.

 

How did you solve the problem?
