[1.12.2] WorldEdit ignores command when inserted with ITextComponent


Recommended Posts

I'm trying to create a mod where the player can load, paste, and undo schematics using custom items, compared to manually typing the text. I got the first part working, but for some reason MCEdit ignores messages posted directly using the ITextComponent, opposed to actually typing the text and hitting enter.


An example of my Paste.class:

package com.mta.utzonmod.items;

import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

import com.mta.utzonmod.client.gui.signInputGui;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemStack;
import net.minecraft.util.ActionResult;
import net.minecraft.util.EnumHand;
import net.minecraft.util.text.ITextComponent;
import net.minecraft.util.text.TextComponentString;
import net.minecraft.world.World;

public class Paste extends ItemBase{ 
	public Paste(String name) {
	static boolean canPlace = false;
	public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer player, EnumHand handIn) {
		if(!worldIn.isRemote) {
			if(canPlace == true) {
				ITextComponent message = new TextComponentString("//paste");
				canPlace = false;
		return super.onItemRightClick(worldIn, player, handIn);	
	public static void setCanPlace(boolean cPlace) {
		canPlace = cPlace;


Is there another component I can use for sending text, or is it a whole other size of problem?

Calling sendMessage on the server sends a message to the player via chat.

If you want to execute a command on behalf of a player, call ICommandManager::executeCommand.

I assume this can't be done client-side? All the examples I see use:

MinecraftServer minecraftserver = MinecraftServer.getServer();

Where I get told MinecraftServer's getServer() isn't static so I can't even call it if I wanted to. How would I implement this in the code from my original post?

To obtain the server instance you can use ICommandSender::getServer (every entity is a command sender).


On the client you can use EntityPlayerSP::sendChatMessage to send a command to the server.

Worked like a charm, thank you very much =)
