Hey Minecraft Forge Modders! I've been trying to make a quick simple mod that allows players to remove their name tag so no other players can see it, but I can't seem to find out how to go about doing this. If somebody could help me do this it would be great! I'm not asking for a full written out code for me, just some pointers to help get me going. Thanks!

I can't figure out how to cancel an event in forge without directly altering it's class, I've been trying to figure this out all morning.

event.setCanceled(true);

Ok so if I were to have a key binding class like this:

package drolive.nonametags;

import java.util.EnumSet;

import net.minecraft.client.settings.KeyBinding;
import net.minecraftforge.client.event.RenderLivingEvent;
import net.minecraftforge.client.event.RenderLivingEvent.Specials;
import cpw.mods.fml.client.registry.KeyBindingRegistry.KeyHandler;
import cpw.mods.fml.common.TickType;

class NoNameTagsKeyBind extends KeyHandler {

private EnumSet tickTypes = EnumSet.of(TickType.CLIENT);

public NoNameTagsKeyBind(KeyBinding[] keyBindings, boolean[] repeatings) {
	super(keyBindings, repeatings);
}

@Override
public String getLabel() {
	return "Hide";
}

@Override
public void keyDown(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd, boolean isRepeat) {



}

@Override
public void keyUp(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd) {

}

@Override
public EnumSet<TickType> ticks() {
	return null;
}

}

How would I cancel RenderLivingEvent.Specials.Pre? Would I have to make another class for my key binding or what?

Ok I made a class for my key binding

package drolive.nonametags;

import net.minecraftforge.client.event.RenderLivingEvent;
import net.minecraftforge.client.event.RenderLivingEvent.Specials;
import net.minecraftforge.event.Event;

public class NoNameTagsKeyBindHide {

public void Pre(Specials.Pre event){
	if (event.isCancelable()) {
        event.setCanceled(true);
}
}
}

but how do I make it so when you press the key it cancels Pre, then if you press it again it doesn't cancel it?

You can store a boolean for the key pressed.

public boolean alreadyPressed = false;

*in your method*
if(!alreadyPressed)
{
*cancel event
}
else
{
*uncancel event*
}

I have my keybindings class and my keybindinghide class without any errors and it show up in the game's control menu, but when I press it in game, nothing happens!

Main Keybinding class:

package drolive.nonametags;

import java.util.EnumSet;

import net.minecraft.client.settings.KeyBinding;
import net.minecraftforge.client.event.RenderLivingEvent;
import net.minecraftforge.client.event.RenderLivingEvent.Specials;
import cpw.mods.fml.client.registry.KeyBindingRegistry.KeyHandler;
import cpw.mods.fml.common.TickType;

class NoNameTagsKeyBind extends KeyHandler {

public static boolean cancelPre = false;

private EnumSet tickTypes = EnumSet.of(TickType.CLIENT);

public NoNameTagsKeyBind(KeyBinding[] keyBindings, boolean[] repeatings) {
	super(keyBindings, repeatings);
}

@Override
public String getLabel() {
	return "Hide";
}

@Override
public void keyDown(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd, boolean isRepeat) {

	if (cancelPre == false){
		cancelPre = true;
	}
	else cancelPre = false;

}

@Override
public void keyUp(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd) {

}

@Override
public EnumSet<TickType> ticks() {
	return null;
}

}

 

My class for the "hide" keybinding:

package drolive.nonametags;

import net.minecraftforge.client.event.RenderLivingEvent;
import net.minecraftforge.client.event.RenderLivingEvent.Specials;
import net.minecraftforge.event.Event;

public class NoNameTagsKeyBindHide {

public void Pre(Specials.Pre event){
	if (event.isCancelable() && NoNameTagsKeyBind.cancelPre == true){
		System.out.println("You are now Hiding!");
        event.setCanceled(true);}
        else if (event.isCancelable() && NoNameTagsKeyBind.cancelPre == false) {
        	event.setCanceled(false);
        	System.out.println("You are not Hiding!");
        }	
   }
}

And yes I did register the key binding in my main class. Anybody know why nothing's happening?

Oh and also here is my main class:

package drolive.nonametags;

import org.lwjgl.input.Keyboard;

import net.minecraft.client.model.ModelBase;
import net.minecraft.client.renderer.entity.Render;
import net.minecraft.client.renderer.entity.RendererLivingEntity;

    @Instance("NoNameTags")
    public static NoNameTags instance;

    @EventHandler
    public void preInit(FMLPreInitializationEvent event) {
    }
    
    @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));
    }
    
    @EventHandler
    public void postInit(FMLPostInitializationEvent event) {
    }
}

You didn't register your event.

MinecraftForge.EVENT_BUS.register(new eventClazz());

 

With your event class having an

@ForgeSubscribe(receiveCanceled=true)

above the method.

 

Yeah I registered the event and everything, but when I load a world it says "You are not hiding!" and it never says anything else no matter how many times I press h.

I feel like my NoNameTagsKeyBindHide class isn't checking if cancelPre changes, but how would I do that?

My keybind hide class:

package drolive.nonametags;

import net.minecraftforge.client.event.RenderLivingEvent;
import net.minecraftforge.client.event.RenderLivingEvent.Specials;
import net.minecraftforge.event.Event;
import net.minecraftforge.event.ForgeSubscribe;

public class NoNameTagsKeyBindHide {

public int makeItStop = 0;

@ForgeSubscribe(receiveCanceled=true)
public void Pre(Specials.Pre event){
	if (NoNameTagsKeyBind.cancelPre == true && makeItStop == 1){
		event.setCanceled(true);
		System.out.println("You are now hiding!");
		makeItStop = makeItStop - 1;
        }
    else if (NoNameTagsKeyBind.cancelPre == false && makeItStop == 0) {
    	event.setCanceled(false);
        System.out.println("You are not hiding!");
        makeItStop = makeItStop + 1;
        }	
   }
}

Note: I added the int makeItStop because before when I would load a world, it would spam the console with never ending "You are not hiding!"

if(NoNameTagsKeyBind.cancelPre){

    //do stuff ?

}

if(NoNameTagsKeyBind.cancelPre){

    //do stuff ?

}

Am I supposed to call the boolean in a different way?

Am I supposed to call the boolean in a different way?

what other way would there be

 

if(NoNameTagsKeyBind.cancelPre == true) ?

if(NoNameTagsKeyBind.cancelPre != false) ?

if(NoNameTagsKeyBind.cancelPre) ?

if(NoNameTagsKeyBind.cancelPre || false) ?

 

 

...all those do the same thing ...

 

 

Yes I know I was just trying to make sense of what you said before. Is the problem that it's not constantly checking if cancelPre is true or false?

*main class*
boolean[] repeat = {true};

Set to false to stop the repeating keybind.

 

@Override
public void keyDown(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd, boolean isRepeat) {
	if(tickEnd)//so it doesn't fire twice
	cancelPre = (!cancelPre);

}

*main class*
boolean[] repeat = {true};

Set to false to stop the repeating keybind.

 

@Override
public void keyDown(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd, boolean isRepeat) {
	if(tickEnd)//so it doesn't fire twice
	cancelPre = (!cancelPre);

}

I tried all this and it still repeats if I dont use makeItStop. And it still wont work in game.

Does anybody know why it's not working?

In your keybinding, you set this field.

private EnumSet tickTypes = EnumSet.of(TickType.CLIENT);

You should use it here:

@Override
public EnumSet<TickType> ticks() {
	return null;
}

instead of null.

Yeah I know I just noticed that... can't believe I never realized it! And I also got it to stop repeating, thanks so much!

Nevermind it doesn't stop repeating without makeItStop...

Also I tried it in a LAN world and it said "You are now hiding!" but it didn't remove the name tag, know why?

    	ModLoader.getMinecraftInstance().thePlayer.addChatMessage("You are not hiding!");
        makeItStop = makeItStop + 1;
        }	
   }
}

Nevermind it doesn't stop repeating without makeItStop...

Of course, my fixes only stop repeats from the input key, not from the event. The event will continue fire endlessly while there is living entities to render (that is, until world is closed).

For now, we have it so cancelPre boolean is only changed once each time you press the key.

We should add so only players have their name tags removed, right ?

So let's do only

if(event.entity instanceof EntityPlayer)
{
event.setCanceled(true);
}

Oh by the way, stop using ModLoader.

I did just what you said but when I press the key in game, nothing happens, it wont even print a text. I also tried using it like this, but still no luck:

if(NoNameTagsKeyBind.cancelPre == true && event.entity instanceof EntityPlayer)

Is this where I'm supposed to put the code?

package drolive.nonametags;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.src.ModLoader;
import net.minecraftforge.client.event.RenderLivingEvent;
import net.minecraftforge.client.event.RenderLivingEvent.Specials;
import net.minecraftforge.event.Event;
import net.minecraftforge.event.ForgeSubscribe;

public class NoNameTagsKeyBindHide {

@ForgeSubscribe(receiveCanceled=true)
public void Pre(Specials.Pre event){
	if(event.entity instanceof EntityPlayer){
        event.setCanceled(true);
        }

Well I got it to cancel the event by using isCanceled(), but it turns out that cancelling Specials.Pre only makes everyone else's names disappear, not the player's who used the command... How would I make it so only the player's disappears from everyone else's view?

Does somebody know the event that renders your own nametag?

it should be the same
