ICommand not recognizing when on server

[Bets]

It's pretty straight forward here.

When I play in a singleplayer world the command works, you can find it using TAB as-well. But when I play on multiplayer the command does not work at all, like it doesn't exist.

Do I need to configure it to work on a server too somehow? I am extending CommandBase in my class file.

It sounds like you're only registering it on the client. You need to register your commands on both physical sides in FMLServerStartingEvent, which needs to be handled by a @Mod.EventHandler method in your @Mod class.

 

If you're doing this and it's still not working, post your code.

Yeah this is what I was doing:

    @EventHandler
    public void serverLoad(FMLServerStartingEvent event) {
        event.registerServerCommand(new testCommand());
    }

Is this in your @Mod class? Are there any errors in the log?

 

Post the testCommand class.

If by @Mod class you mean the main class that has the mod name in it, then yes, it is.

 

This is the test command class:

public class testCommand extends CommandBase {
    @Override
    public String getCommandName() {
        return "test";
    }
    @Override
    public String getCommandUsage(ICommandSender sender) {
        return "/<command>";
    }
    
    @Override
    public int getRequiredPermissionLevel() {
        return 0;
    }
    
    @Override
    public boolean canCommandSenderUseCommand(ICommandSender sender) {
        return true;
    }
    @Override
    public void processCommand(ICommandSender sender, String[] args) throws CommandException {
        if (sender instanceof EntityPlayer) {
            EntityPlayer player = (EntityPlayer) sender;
            player.addChatComponentMessage(new ChatComponentText("Works!"));
        }
    }
}

Did you install your mod on the server as well?

No, it should be a Client only command.

And the names FMLServerStartingEvent and registerServerCommand did not make you suspicious then? 

For client-side commands you need to use ClientCommandHandler.

Expand  

 

Changed it to this one:

    @EventHandler
    public void serverLoad(ClientCommandHandler event) {
        event.registerCommand(new testCommand());
    }

 

Now it doesn't work not in single and not on multiplayer.

I think I tried using this before and it just didn't work so I used the server one.

ClientCommandHandler isn't an event, you can't subscribe to it. You need to call ClientCommandHandler#registerCommand from your client proxy in preInit.

 

There should be an error in the log telling you that the method is invalid.

I have this in my preinit

    @Mod.EventHandler
    public void preInit(FMLPreInitializationEvent e) {
        MinecraftForge.EVENT_BUS.register(new THING());
        
    }

How do I call  ntCommandHandler#registerCommand?

You call it like any other method.

So like the "new THING" one?

I am a little new to it, I do understand it but not everything 100% just yet. Most of my stuff I was doing in JavaScript or ActionScript.

Well, the "new THING" is creating an object. You need to call a method.

This method is a mc method? how do you call something like this

[Draco18s]

How do you call any other method?

 

You get an instance of an object and press the . key and type the method name...

Yes I know, but where should I call it, inside my @Mod class? how do I do this? should it be inside my preinit? what should be before it?

[Draco18s]

...yes...

I'm a little lost right now...

I have a class that extends CommandBase, there I give it the command name, usage etc.

Do I need to call that class from my preinitevent (I need to perhaps register it?), right? How do I do that? just like I did for my "THING" class? or there is some other way to do so?

The command class is called testCommand, and as I said before extends CommandBase. So I should just add this line to my preinit?

MinecraftForge.EVENT_BUS.register(new testCommand());

 

[shadowfacts]

No. It's a command, not an event handler, and furthermore, it's a client-side command. You need to register it with the ClientCommandHandler instance in your pre-init event. 

 

You should really learn Java before trying to mod, it will make your life a lot easier. Right now you're making a lot of mistakes that you wouldn't be if you had a basic knowledge of Java.
