[1.7.10] Use Events

[daniel0916]

Hello guys,

 

i'm a beginner in Forge Development and i have a problem with using events.

 

Code:

@Mod(modid = Test.MODID, version = Test.VERSION)
public class Test {
    public static final String MODID = "Test";
    public static final String VERSION = "1.0";
    
    @EventHandler
    public void init(FMLInitializationEvent event) {
    	MinecraftForge.EVENT_BUS.register(new CommandListener());
    	
    	//FMLCommonHandler.instance().bus().register(new ExecuteEvent());
    }
}

 

public class CommandListener {

public void onCommand(CommandEvent event) {
	System.out.println(event.command);
}
}

 

I don't get the message. What's wrong?

 

Thanks for reading my question.

 

Greetings

Daniel

Okay, it works.

 

But it's the wrong event. Which event can i use for getting the command who is a player executing on a server. When i connect to a server and make "/test" the event should be called.

[daniel0916]

Yes, but then the mod needs to be installed on the server or?

 

But i want to have this command only client-side. I only had modified minecraft directly with mcp before...

[Ernio]

ClientCommandHandler.instance.registerCommand(new YourCommand());

 

 

[daniel0916]

Big thanks. That's working. Now, i only have a permission problem. Maybe i can find the solution with searching .

[daniel0916]

Do I need to overwrite canCommandSenderUse?

[daniel0916]

public int getRequiredPermissionLevel() {
        return 0;
    }

 

Fixed my problem. And can i use a event for right clicking with an item? client-side?

[Ernio]

Depends what event are you talking about. There are few (use, interact, mouse click, more...).

 

Most of events are executed on both sides. Some are only on server and some will work only on client (and in most cases send info to server using vanilla packet).

 

What exacly do you need?

[daniel0916]

When i have a item in my hand and right click the event should be called. So mouse click.

[Ernio]

Not really.

If you want event to be called for EVERY item:

PlayerUseItemEvent

This event is separated in sub-phase events, make sure you picked right one.

 

Simply check side for event to be launched on client.

 

If you'd have your OWN items, you can @Override Item#onItemRightClick(...)

[daniel0916]

Okay, but the event doesn't get called.

 

@SubscribeEvent
public void onItemUse(PlayerUseItemEvent event) {
	System.out.println(event.item.getItem());
	System.out.println(Item.getIdFromItem(event.item.getItem()));
}

 

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

 

"This event is separated in sub-phase events, make sure you picked right one."

What do you mean with this exactly?

 

Edit: Ah, okay. I understand it now.

 

Edit2: Okay, the event is working when i block with the sword but i need a event which get called when i make right-click with a compass.

[Ernio]

PlayerInteractEvent then.

 

* This event is fired whenever a player interacts in
* Minecraft#rightClickMouse(),

 

I used it only once, very long time ago and I remember having problems with certain clicking (the righclick wasnt always calling event).

It probably changed now.

 

For certain I know that Client will always get called no matter on what you click since it's called directly from Minecraft#rightClickMouse().

[daniel0916]

Thanks. Perfectly working .

 

So only one last question: How can i execute a command with forge? I understand how to send chat messages but i don't find something for commands.

[Ernio]

Extend CommandBase or wider implement ICommand.

In execute() you write what should happen.

getName() is your command. e.g "test" will give you /test.

 

AS for registering:

Server:

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

and Client:

ClientCommandHandler.instance.registerCommand(new CommandTest());

 

Note: For client registration MUST be done in ClientProxy.

Also: server will NEVER receive client commands (they are totally local).

 

EDIT: Note 2: Registering command for server doesn't require you to ALSO register it for client. You do it either for client only, or for Server (which is server+client)
