Problems with ChatCommands

[chris140989]

Hey there,

I have a problem with ChatCommands aka ServerCommands. First of all i tried creating one by myself with this guide (http://www.minecraftforge.net/wiki/Server_Command), but it seems outdated. I tried to find a solution by myself but couldn't find any working example on this.

 

I believe that my main problem is that I can't register the event since event.registerServerCommand(myCommand()); doesn't work or is not existence anymore.

 

Here is my sourcecode:

 

BaseMod:

package minecraftHamster;

import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.fml.common.FMLCommonHandler;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.Mod.Instance;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPostInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;

public class MinecraftHamster {
// Set the ID of the mod (Should be lower case).
public static final String MODID = "MinecraftHamster";
// Set the "Name" of the mod.
public static final String MODNAME = "MinecraftHamster";
// Set the version of the mod.
public static final String MODVER = "0.0.1";

// Tell Forge what instance to use.
@Instance(value = MinecraftHamster.MODID)
public static MinecraftHamster instance;

@EventHandler
public void preInit(FMLPreInitializationEvent event) {

}

@EventHandler
public void load(FMLInitializationEvent event) {
	event.registerServerCommand(new StartHamsterCommand());
}

@EventHandler
public void postInit(FMLPostInitializationEvent event) {

}
}

 

ChatCommandClass:

package minecraftHamster;

import java.util.List;

import net.minecraft.command.CommandException;
import net.minecraft.command.ICommand;
import net.minecraft.command.ICommandSender;
import net.minecraft.util.BlockPos;
import net.minecraft.util.ChatComponentTranslation;
import net.minecraft.util.IChatComponent;

public class StartHamsterCommand implements ICommand {
private String commandName = "startHamster";

@Override
public int compareTo(Object arg0) {
	// TODO Auto-generated method stub
	return 0;
}

@Override
public String getName() {
	return this.commandName;
}

@Override
public String getCommandUsage(ICommandSender sender) {
	return this.commandName;
}

@Override
public List getAliases() {
	// TODO Auto-generated method stub
	return null;
}

@Override
public void execute(ICommandSender sender, String[] input) throws CommandException {
	if (input.equals(this.commandName)) {
		sender.addChatMessage(new ChatComponentTranslation("Hamster wird gestartet.."));
	} else {
		sender.addChatMessage(new ChatComponentTranslation("This is not a command"));
		return;
	}

}

@Override
public boolean canCommandSenderUse(ICommandSender sender) {
	return true;
}

@Override
public List addTabCompletionOptions(ICommandSender sender, String[] args, BlockPos pos) {
	// TODO Auto-generated method stub
	return null;
}

@Override
public boolean isUsernameIndex(String[] args, int index) {
	// TODO Auto-generated method stub
	return false;
}

}

 

Any advice on this would be awesome..

 

Another question: Is there a documentation for Forge anywhere? Cause I have the feeling that kind of any tutorial is outdated and nearly all methods got changed..

[chris140989]

Oh my god.. you are right, didn't see that it is another EventType.

 

Changed it and now I can use event.registerServerCommand(new myCommand()); but when I try to use this command in Minecraft, it says that the command does not exist.

 

@Override
public String getCommandUsage(ICommandSender sender) {
	return "startHamster";
}

 

If I make the commandUsage like this, it should be possible to trigger the command with /startHamster in Minecraft right?

[chris140989]

I can't see the problem then..

 

Here are the current classes again.

 

BaseMod:

public class MinecraftHamster {
// Set the ID of the mod (Should be lower case).
public static final String MODID = "MinecraftHamster";
// Set the "Name" of the mod.
public static final String MODNAME = "MinecraftHamster";
// Set the version of the mod.
public static final String MODVER = "0.0.1";

// Tell Forge what instance to use.
@Instance(value = MinecraftHamster.MODID)
public static MinecraftHamster instance;

@EventHandler
public void preInit(FMLPreInitializationEvent event) {

}

@EventHandler
public void load(FMLServerStartingEvent event) {
	event.registerServerCommand(new StartHamsterCommand());
}

@EventHandler
public void postInit(FMLPostInitializationEvent event) {

}
}

 

StartHamsterCommand:

public class StartHamsterCommand implements ICommand {
private List aliases;

public StartHamsterCommand() {
	this.aliases = new ArrayList();
	this.aliases.add("startHamster");
}

@Override
public int compareTo(Object arg0) {
	// TODO Auto-generated method stub
	return 0;
}

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

@Override
public String getCommandUsage(ICommandSender sender) {
	return "startHamster";
}

@Override
public List getAliases() {
	return this.aliases;
}

@Override
public void execute(ICommandSender sender, String[] input) throws CommandException {
	sender.addChatMessage(new ChatComponentTranslation("Hamster wird gestartet.."));
}

@Override
public boolean canCommandSenderUse(ICommandSender sender) {
	return true;
}

@Override
public List addTabCompletionOptions(ICommandSender sender, String[] args, BlockPos pos) {
	// TODO Auto-generated method stub
	return null;
}

@Override
public boolean isUsernameIndex(String[] args, int index) {
	// TODO Auto-generated method stub
	return false;
}
}

Alright, changed my class so it will extend CommandBase. The compareTo method i deleted and the aliases I won't need either so i deleted them aswell.

 

Found another mistake I made: I totally forgot about the @Mod annotation in the base Mod file, which obviously was the error why it didn't worked.

 

Thanks for your time and help

I have some problems with that Tutorial also.

 

It does work, but for some reason it wont let me load already generated worlds. I just hangs.

- Don't hijack threads.

- Post your code.

 

What you talking about? I didn't hijack anything...

 

I just letting the Original Poster know that the Tutorial is working.
