Remove Name Tag Mod

[DrOlive]

I got the Pre event to cancel, but it just removes everyone else's name from the person who used it's view

[hydroflame]

might be a bug then :\

[DrOlive]

I'll just have to work with it I guess

[DrOlive]

Is there a way I could make it so if one player uses it, it cancels the event for all the players, including himself?

[hydroflame]

beside the "including himself" part (because it doesnt work )

 

make a list/hashmap in your client proxy and when someone uses the item/spell/command to hide his name, send a packet to the server that tell that. then the server need to keep track of who is hiding and who isnt (for when a new player logs in) and then the server send a packe to all player to change its "mode" to hidden/non-hidden

when a new player log in just fill him with the details of who is hidden and who isnt

[DrOlive]

Ok thanks I'll do this later today

huehuehuehuehuehue kidding

[DrOlive]

Hahahaha ok

[DrOlive]

So do you think I could do it like the packet would send an int to everyone and depending on the int(0 or 1) it would change their "mode"?

[hydroflame]

basicly yes

or you could have a hashmap<String, Boolean> to make things simpler

[DrOlive]

Ok so I'm new to packets (Never really needed them before) and I made it so it reads the int when I send it, but how do I make it cancel the event? I tried putting my cancel event in my packet handler, but it gave me the error, "void is an invalid type for the variable Pre". I'm making it so if the int cancelPre == 0, then it uncancels, and if it equals 1, it cancels.

[hydroflame]

im not quite sure what you did ... can you post code ?

[GotoLink]

I think the simplest way would be to make the keyhandler send the packet, the packethandler to receive it and then change a variable in your event class.

[DrOlive]

Well I decided I'm making a block that when you right click it, it changes the mode to hidden

Block class:

package drolive.nonametags;

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

import cpw.mods.fml.common.FMLCommonHandler;
import cpw.mods.fml.common.network.PacketDispatcher;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.player.EntityPlayerMP;
import net.minecraft.network.packet.Packet250CustomPayload;
import net.minecraft.world.World;

public class NoNameTagsHideBlock extends Block {

public static int cancelPre = 0;

public NoNameTagsHideBlock(int id){
	super(id, Material.iron);
	setUnlocalizedName("hideBlock");
	func_111022_d("nonametags.hideBlock");
	setCreativeTab(CreativeTabs.tabBlock);
}

@Override
public boolean onBlockActivated(World world, int bx, int by, int bz, EntityPlayer playerEntity, int unknown, float px, float py, float pz){
	if(cancelPre == 0){
		cancelPre = cancelPre + 1;
	}
	else if(cancelPre == 1){
		cancelPre = cancelPre + 1;
	}
	else if(cancelPre == 2){
		cancelPre = cancelPre - 2;
	}

	ByteArrayOutputStream bos = new ByteArrayOutputStream(4);
	DataOutputStream outputStream = new DataOutputStream(bos);
	try {
		outputStream.writeInt(cancelPre);
	} catch (Exception ex) {
		ex.printStackTrace();
	}
	Packet250CustomPayload packet = new Packet250CustomPayload();
	packet.channel = "NoNameTagsCancel";
	packet.data = bos.toByteArray();
	packet.length = bos.size();

	Side side = FMLCommonHandler.instance().getEffectiveSide();
	if(side == Side.SERVER){
		EntityPlayerMP player = (EntityPlayerMP) playerEntity;
		PacketDispatcher.sendPacketToAllPlayers(packet);
	}
	else if(side == Side.CLIENT){
		EntityClientPlayerMP player = (EntityClientPlayerMP) playerEntity;
	}
	else{
	}

	return false;
}

}

public class NoNameTags {

public static final Block hideBlock = new NoNameTagsHideBlock(3500);

    @Instance("NoNameTags")
    public static NoNameTags instance;
    
    @SidedProxy(clientSide="drolive.nonametags.client.ClientProxy", serverSide="drolive.nonametags.CommonProxy")

    	LanguageRegistry.addName(hideBlock, "Hide Block");
    }
    
    @EventHandler
    public void load(FMLInitializationEvent event) {
            proxy.registerRenderers();
            KeyBinding[] key = {new KeyBinding("Hide", Keyboard.KEY_H)};
            boolean[] repeat = {false};
            KeyBindingRegistry.registerKeyBinding(new NoNameTagsKeyBind(key, repeat));

}

Packet Handler class:

package drolive.nonametags;

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

import net.minecraft.network.INetworkManager;
import net.minecraft.network.packet.Packet250CustomPayload;
import cpw.mods.fml.common.network.IPacketHandler;
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("NoNameTagsCancel")){
		handleCancelPre(packet);
	}
}

private void handleCancelPre(Packet250CustomPayload packet){
	DataInputStream inputStream = new DataInputStream(new ByteArrayInputStream(packet.data));

	int cancelPre;

	try{
		cancelPre = inputStream.readInt();
	} catch(IOException e){
		e.printStackTrace();
		return;
	}
	System.out.println("Cancel Pre = " + cancelPre);
}

}

And here's the code for cancelling the event:

@ForgeSubscribe(receiveCanceled=true)
public void Pre(Specials.Pre event){
	if(cancelPre == 1 || cancelPre == 2){
        event.setCanceled(true);
        event.isCanceled();
        }

[hydroflame]

the block shouldnt be holding the state

 

your client proxy should be holding the hide state

whenever the block is activated it send a packet to the server saying "i change my state to state : *insert state*"

then the server will update HIS list of state and send the new player state to ALL player in the server

 

[DrOlive]

So where would I make the list, and where should I make the packet that gets sent to all the players? In one of my proxies?

[hydroflame]

So where would I make the list

which one are we talking about?

 

where should I make the packet that gets sent to all the players?

some place that you have access to the server list of hide state

[DrOlive]

which one are we talking about?

The list of which players are hiding/ not hiding that the server keeps

[hydroflame]

the list can be in your server packet handler i guess

[DrOlive]

I still don't understand how to make it so when a player receives the packet, it changes their mode to hidden

[hydroflame]

String username = // the username you need to update

int newMode = //the new hide mode ex 0 for hidden 1 for visible

MainMod.proxy.hideMap.put(username, newMode)

[GotoLink]

I wouldn't call it "hidding" since the player which has his event canceled won't see other people tag.

It would make more sense to call it "blind". 

 

You can put the list of players in the event class, it doesn't really matter as long as it is accessible for the server.

Using a map like hydroflame suggested.

[hydroflame]

blindMap.get(username)=newMode;

???

that wont work  *suspicious look*
