[1.6.4] [SOLVED] KeyBinding multiplayer problem

[Jacky2611]

Hi!

I have some problems with the key binding for server.

 

for sigleplayer i use:

 

in the main class

		KeyBindingRegistry.registerKeyBinding(new DimensionShiftKeyHandler());

	TickRegistry.registerTickHandler(new PlayerTickHandler(EnumSet.of(TickType.PLAYER)), Side.SERVER);

Key registry

 

package net.dimensionshift.mod;

import java.util.EnumSet;

import net.minecraft.client.Minecraft;
import net.minecraft.client.settings.KeyBinding;
import net.minecraft.network.packet.NetHandler;

import org.lwjgl.input.Keyboard;

import cpw.mods.fml.client.FMLClientHandler;
import cpw.mods.fml.client.registry.KeyBindingRegistry.KeyHandler;
import cpw.mods.fml.common.TickType;
import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;

public class DimensionShiftKeyHandler extends KeyHandler {

@SideOnly(Side.CLIENT)
    static KeyBinding SpecialAbility = new KeyBinding("test", Keyboard.KEY_H);
public static boolean keyPressedTest;



    public DimensionShiftKeyHandler() {
            //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[]{SpecialAbility}, new boolean[]{false});
    }

    @Override
    public String getLabel() {
    	  return "DimensionShiftKeyBindings";
    	}
    
@Override
public void keyUp(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd) {
	// TODO Auto-generated method stub

}
    @Override
    public void keyDown(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd, boolean isRepeat) {
            //do whatever
    	
	if (kb.keyCode == SpecialAbility.keyCode) {
		keyPressedTest = true;
	}


    }


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

    }


}

 

 

TickHandler

 

package net.dimensionshift.mod;

import java.util.EnumSet;
import net.dimensionshift.mod.DimensionShiftKeyHandler;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.world.World;
import cpw.mods.fml.common.ITickHandler;
import cpw.mods.fml.common.TickType;
public class PlayerTickHandler implements ITickHandler
{
private final EnumSet<TickType> ticksToGet;

/*
         * This Tick Handler will fire for whatever TickType's you construct and register it with.
         */
public PlayerTickHandler(EnumSet<TickType> ticksToGet)
{
         this.ticksToGet = ticksToGet;
}
/*
         * I suggest putting all your tick Logic in EITHER of these, but staying in one
         */
@Override
public void tickStart(EnumSet<TickType> type, Object... tickData)
{
         playerTick((EntityPlayer)tickData[0]);
}
@Override
public void tickEnd(EnumSet<TickType> type, Object... tickData)
{
}
@Override
public EnumSet<TickType> ticks()
{
         return ticksToGet;
}
@Override
public String getLabel()
{
         return "TutorialPlayerTick";
}

public static void playerTick(EntityPlayer player)
{
         if(DimensionShiftKeyHandler.keyPressedTest==true){
        	
        	 //maybe spawn a few particles at player position
        		 
        	System.out.println(player.getEntityName() + " did something...");	 
        	
         }
}
}

 

 

This code works good in ssp, but my server crashes on startup.(userinput is completely new for me...)

 

As far as i understand i have to add a packet handler. Can someon give me a hint how to this?

(I need the coordinates + name of the player who pressed the button)

 

    thx in advance, Jacky

Look at the packet tutorials on the wiki.

[Jacky2611]

Yeah, i know that i have to use packets...

But i don't know how to send the players name with packets/how i can figure out who sent the package...

everything else shouldn't be a problem.

Packets coming from a player will pass a player entity to your packet handler.

 

Its like magic:

 

public void onPacketData(INetworkManager manager, Packet250CustomPayload packet, Player player) {  }

I idiot stupid...

EDIT(couldn' Edith original post):

but in order to send a packet i need the player.

How do i geht the player inside the keybinding class?

 

Also, as far as i know, i need an entity player/entity player mp in order to do anything with him. how do i convert player to entity player?

Player is an interface added by forge to EntityPlayer. Casting is safe.

 

Only one player on client:

Minecraft#thePlayer

Oh... Then one problem is solved.

But how do i geht the player inside my keybinding Class to send the packet?

Minecraft#thePlayer

But how should i send the packet if i don't have the player?

player.sendQueue.addToSendQueue(packet);

 

Or should i send the packet inside my tickhandler?  (Would like to get rid of it since i don't need it for anything else.)

You DO have the player, that's what they've been trying to tell you:

EntityPlayer player = Minecraft.getMinecraft().thePlayer;

Minecraft.getMinecraft() returns the client instance of Minecraft, which always has a reference to the client side player and world objects.

 

But that's a moot point: when sending packets to the server, you don't need an instance of the player because the server already knows from whom it came...

Thx, this is exactly what i want.

 

But how can i send a packet without the player? if i understood the code on the wiki correct i need the player object to send the packet. Is there any other way to send a packet?

[coolAlias]

Use PacketDispatcher.sendPacketToServer(whatever Packet you made goes here);
