I am not sure why, but my commands in the mod I am writing seem to not be registering properly. I have tried all sorts of things, including looking at prior functioning code and tutorials, but none of it is working.

When I do /help, it is not listed there, nor is it listed when I press / then tab.

 

Here is one of the commands, which generates and builds a maze by id.

package dcn.mazegen.commands;

import java.util.ArrayList;
import java.util.List;

import dcn.mazegen.Maze;
import net.minecraft.command.CommandBase;
import net.minecraft.command.CommandException;
import net.minecraft.command.ICommand;
import net.minecraft.command.ICommandSender;
import net.minecraft.server.MinecraftServer;
import net.minecraft.util.math.BlockPos;
import net.minecraft.util.text.TextComponentString;

public class CmdBuild extends CommandBase{

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

	@Override
	public String getUsage(ICommandSender sender) {
		return "buildmaze <id>";
	}

	@Override
	public void execute(MinecraftServer server, ICommandSender sender, String[] args) throws CommandException {
		if(args.length == 0) {
			sender.sendMessage(new TextComponentString("Too few args"));
			return;
		}
		boolean found = false;
		for(Maze m : Maze.mazeList) {
			if(m.id.equals(args[0])) {
				found = true;
				sender.sendMessage(new TextComponentString("Generating maze...."));
				m.generate();
				sender.sendMessage(new TextComponentString("Generated, building maze...."));
				m.build();
				sender.sendMessage(new TextComponentString("Maze built."));
				break;
			}
		}
		if(!found)
			sender.sendMessage(new TextComponentString("Could not find maze with id \"" + args[0] + "\"."));
	}
}

 

Here is the main class, with the @Mod annotation.

package dcn.mazegen;

import dcn.mazegen.commands.CmdBuild;
import dcn.mazegen.commands.CmdMaze;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.Mod.Instance;
import net.minecraftforge.fml.common.event.FMLServerStartingEvent;

@Mod(modid = MazeGenerator.MODID, name = MazeGenerator.NAME, version = MazeGenerator.VERSION)
public class MazeGenerator {
	public static final String MODID = "MazeGenerator";
	public static final String NAME = "Maze Generator";
	public static final String VERSION = "0.0";

	@Instance
	public static MazeGenerator instance;
	
	@EventHandler
	public void onServerLoad(FMLServerStartingEvent e) {
		e.registerServerCommand(new CmdMaze());
		e.registerServerCommand(new CmdBuild());
	}
}

 

I am using Forge version 1.12.2 - 14.23.4.2705 and Java version 1.8.0_171.

Adding code change

methods annotated with

@EventHandler

cannot be static

Thank you, I missed that. I feel kinda dumb now....

 

Do I have to mark this as closed or anything?

You could add [SOLVED] to the title but no need

Actually, in testing, it still isn't working. I changed the event handler to not be static.

 

Edit: Figured it out

I read through the logs and saw this line

java.lang.IllegalArgumentException: The modId MazeGenerator must be all lowercase.

 

Now I feel even dumber

Do you need help with that error, or not?

I figured it out. I had not realized mod ids had to be lower case, so the entire mod wasn't active. Since the mod so far only adds commands, I hadn't noticed.
