So I'm working on a mod and I made a command. When I try and execute the command, it says I don't have permission. Here's the class:

 

package com.reprevise.enhanmod.cmds;

import java.util.List;

import com.reprevise.enhanmod.chat.PluginAnnouncer;

import net.minecraft.command.CommandBase;
import net.minecraft.command.CommandException;
import net.minecraft.command.ICommand;
import net.minecraft.command.ICommandSender;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.server.MinecraftServer;
import net.minecraft.util.math.BlockPos;
import net.minecraftforge.client.IClientCommand;

public class PunishCMD extends CommandBase {

	@Override
	public String getName() {
		return "punish";
	}

	@Override
	public String getUsage(ICommandSender sender) {
		return "/punish <user>";
	}

	@Override
	public void execute(MinecraftServer server, ICommandSender sender, String[] args) throws CommandException {
		
		if (sender instanceof EntityPlayer) {
			EntityPlayer player = (EntityPlayer) sender;
			PluginAnnouncer.sendMessageToMod("Opening GUI...");
		}
		
	}

	@Override
	public boolean checkPermission(MinecraftServer server, ICommandSender sender) {
		return false;
	}
	
	@Override
	public boolean isUsernameIndex(String[] args, int index) {
		return false;
	}

}

 

Look at the other methods in the class you're extending (CommandBase). There are methods there regarding permissions you need to override.

package com.reprevise.enhanmod.cmds;

import java.util.List;

import com.reprevise.enhanmod.chat.PluginAnnouncer;

import net.minecraft.command.CommandBase;
import net.minecraft.command.CommandException;
import net.minecraft.command.ICommand;
import net.minecraft.command.ICommandSender;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.server.MinecraftServer;
import net.minecraft.util.math.BlockPos;
import net.minecraftforge.client.IClientCommand;

public class PunishCMD extends CommandBase {

	@Override
	public String getName() {
		return "punish";
	}

	@Override
	public String getUsage(ICommandSender sender) {
		return "/punish <user>";
	}

	@Override
	public void execute(MinecraftServer server, ICommandSender sender, String[] args) throws CommandException {
		
		if (sender instanceof EntityPlayer) {
			EntityPlayer player = (EntityPlayer) sender;
			PluginAnnouncer.sendMessageToMod("Opening GUI...");
		}
		
	}

	@Override
	public boolean checkPermission(MinecraftServer server, ICommandSender sender) {
		return false;
	}
	
	@Override
	public int getRequiredPermissionLevel() {
		return 0;
	}
	
	@Override
	public boolean isUsernameIndex(String[] args, int index) {
		return false;
	}

}

This is my new class, and the only thing I changed was overriding the getRequiredPermissionLevel method which didn't help. I went through the class and there were no other methods that dealt with permissions.

Alright, I fixed the issue. Here's my final class.

package com.reprevise.enhanmod.cmds;

import com.reprevise.enhanmod.chat.PluginAnnouncer;

import net.minecraft.command.CommandBase;
import net.minecraft.command.CommandException;
import net.minecraft.command.ICommandSender;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.server.MinecraftServer;

public class PunishThing extends CommandBase {

	@Override
	public String getName() {
		// TODO Auto-generated method stub
		return "punish";
	}

	@Override
	public String getUsage(ICommandSender sender) {
		// TODO Auto-generated method stub
		return "/punish <user>";
	}

	@Override
	public void execute(MinecraftServer server, ICommandSender sender, String[] args) throws CommandException {
		if (sender instanceof EntityPlayer) {
			EntityPlayer player = (EntityPlayer) sender;
			PluginAnnouncer.sendMessageToMod("Opening GUI...");
		}
		
	}

	@Override
	public int getRequiredPermissionLevel() {
		// TODO Auto-generated method stub
		return super.getRequiredPermissionLevel();
	}

	@Override
	public boolean checkPermission(MinecraftServer server, ICommandSender sender) {
		// TODO Auto-generated method stub
		return super.checkPermission(server, sender);
	}

}
