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

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

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?

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;

} 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(); }

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.

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"?

Hahahaha ok

Ok thanks I'll do this later today

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

I'll just have to work with it I guess

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

Does somebody know the event that renders your own nametag?

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?

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); }

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?
