[1.15.2] Command doesn't exist after inputting arguments

So I want to create a command to teleport between dimensions, for testing, but when I try to run it, the game says

"Unknown Command"
"...dimension_name_here <--[HERE]"
And I also tried using breakpoints but they didn't trigger whatsoever??

Command Class:
 

public class TeleportDimensionCommand {
    public static void register(CommandDispatcher<CommandSource> dispatcher) {
        LiteralArgumentBuilder<CommandSource> builder = Commands.literal("teleport_dimension").requires(source -> source.hasPermissionLevel(2));
        builder.then(Commands.argument("dimension", DimensionArgument.getDimension()));
        builder.executes(TeleportDimensionCommand::teleport); //Only breakpoint which triggered
        LiteralCommandNode<CommandSource> teleport_dimension = dispatcher.register(builder);
        dispatcher.register(Commands.literal("tp_dim").requires(source -> source.hasPermissionLevel(2)).redirect(teleport_dimension));
    }

    private static int teleport(CommandContext<CommandSource> context) {
        ServerPlayerEntity player;
        try {
            player = context.getSource().asPlayer(); //Put a breakpoint here..
            player.sendMessage(new StringTextComponent("Attempting teleport...")); //When I didn't put any arguments, this popped up in chat
        } catch (CommandSyntaxException e) {
            Main.getLogger().error(Markers.ERROR, "Could not get player from source");
            e.printStackTrace();
            return 0; //Also tried a breakpoint here
        }
        if(player.changeDimension(DimensionArgument.getDimensionArgument(context, "dimension")) == null) {
            Main.getLogger().error(Markers.ERROR, "Could not teleport player"); //Put a breakpoint here
            player.sendMessage(new StringTextComponent("Could not teleport"));
        } else {
            player.sendMessage(new StringTextComponent("Teleported!")); //Put a breakpoint here
        }
        return 1;
    }
}

In my main class:

package sdt.undergroundadditions;

//Imports here...

@Mod("undergroundadditions")
public class Main {
    public Main() {
      	//Some more code here..
        IEventBus forge = MinecraftForge.EVENT_BUS;

        //Adding listeners here...
        forge.addListener(this::serverStarting);
    }
  	//Some more methods in between here
    private void serverStarting(FMLServerStartingEvent event) {
        TeleportDimensionCommand.register(event.getCommandDispatcher());
        logger.info(Markers.SERVER_STARTING, "Initialized server starting events");
    }
}

And, there's no error in the logs too. What's wrong?

Did you launch the project in debug mode? I don't know how intellij does it, but I know with eclipse you have to run the project in debug mode, not normal run, to get breakpoints to work. If it still doesn't break, set a breakpoint somewhere you KNOW the code is reaching, just to make sure it's debugging properly.

Beyond that not sure about  commands, not something I've messed with yet, but if you can get debug to work I'm sure that'll help!

Yes I did press debug mode... Let me just use another breakpoint somewhere..

    • Minecraft java and forge seem to have it out for me, any ideas? I have had issues with exit code 1 while loading forge -fabric was having the same issues, but I seemed to fix it in these repairs? (tried different versions upwards from 1.19 to 1.20.2 for forge, nothing worked and I'm confident older versions wouldn't either) -The launcher itself loads fine, it will load the game within the launcher, and then crash the moment it tries to load outside of the launcher. I have tried the default launcher, legacy launcher, and the curse forge launcher, none have worked! (all have had the same problem) I think this started when I took a break and upgraded to windows 11 and wonder if that changed anything? I have tried the following: uninstalled & reinstalled java, (I have having issues where I download jdk 17 but only 8 would show up (would not show up anywhere but the control panel, not even the official uninstaller, I *think* I got that fixed) tried jarfix uninstalled & reinstalled minecraft tried alternate launchers -forge & legacy, & repaired them too. tried without mods updated game drivers uninstalled and reinstalled forge -including completely wiping it from my system changed java excutable path followed everything in the error code 1 post completely reset my pc I tried to change the launch path but couldn't seem to get it to work -the default launcher wont let me even see properties as an option, i have yet to try with the other two (i did try on legacy but it was being weird) I want to include my debug log; but its over the max size? sorry my brains gone numb from trying to fix this for the past 2 days
    • I personally create registries using DataPackRegistryEvent.NewRegistry. It's pretty powerful as long as you know how to make codecs. In some class, make a registry key like so: public static final ResourceKey<Registry<MyDataType>> MY_REGISTRY = ResourceKey.createRegistryKey(new ResourceLocation(MyMod.MOD_ID, "registry_name")); This will make a registry that holds objects of type "MyDataType". JSON files stored in data/<datapack_namespace>/modid/registryname/ will be parsed and put into this registry. Note that the directory structure has a folder named after your mod inside your datapack directory, so the actual path would look like: data/my_mod/my_mod/registry_name (or if another mod uses your registry: data/their_mod/my_mod/registry_name. To register this registry, subscribe to the DataPackRegistryEvent.NewRegistry event on the MOD event bus and call event.dataPackRegistry() for every registry you have. An example of what I'm doing for my mod (this is in the constructor for the main mod file): IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus(); bus.addListener((DataPackRegistryEvent.NewRegistry event) -> { event.dataPackRegistry(ModRegistries.INSULATOR_DATA, InsulatorData.CODEC); }); CODEC is a public static field inside the class for the custom data type I am registering. It holds a Codec<InsulatorData> that tells Minecraft how to serialize/deserialize the data. Most of my data so far can be represented by records, so I use RecordCodecBuilder.create() to do this: public static final Codec<InsulatorData> CODEC = RecordCodecBuilder.create(instance -> instance.group( // Yadda yadda ).apply(instance, InsulatorData::new)); What exactly to put here depends on what you're trying to do, so that's up to you. But basically you're just defining a list of codecs that correspond to the parameters of the record (data type). Most primitive data types have records in the Codec class (ex. Codec.INT) that you can use, and other classes like ResourceLocation have their own codecs as a static field (ex. ResourceLocation.CODEC). Hopefully this is what you're looking for, and that this helps.
    • Good days  I finnaly manage to fix and get a working gui from BlockItem and from BlockEntity the next issues i have to fix is this the block Entity model for some reason is moved to the south west  this briefcase model must be centered but is moved to a side, i have nothing weird in the code but this is happening // ########## ########## ########## ########## @Override public RenderShape getRenderShape(BlockState blkstate) {     return RenderShape.MODEL; } the block model is out of place However The hitBox of the block is right in place   ########################################################################################################### This next issue  Mi gui also adds the 5 slots from the player equipment the thing is theres no filter to determine whats can be put in an armor slot and what not      i have this method that draws the slots for the armor, the part i dont get i slike wheres the code that responds when you set an item in a item slot to do checks and allow the item to be set or not  //########## ########## ########## //Draw Player Armor private void addPlayerArmorSlots(Inventory playerInventory) { // 36 this.addSlot(new Slot(playerInventory, 39, 8, 8)); this.addSlot(new Slot(playerInventory, 38, 8, 26)); this.addSlot(new Slot(playerInventory, 37, 8, 44)); this.addSlot(new Slot(playerInventory, 36, 8, 62)); this.addSlot(new Slot(playerInventory, 40, 26, 53)); }   theres must be a method that triggers when you set a itemstack inside an slot and allows to do a check if its a valid item for that slot                                             
    • No like how do I use my new PreperableReloadListener, I know how to set it up now and register it, I just need to know how to use it in other classes.
    • Completely out of the blue my forge loader is lagging, although at 120 fps. Like when I turn it lags, or hit mobs it lags, or run sometimes although staying at 120 fps. I found another person having a similar problem:  But there was no solution I dont think. I tried everything from: 1. Updating my computer 2. Updating/reinstalling forge 3. Testing if allocated memory was problem (if it was low or high or mid nothing changed) 4. Adding various performance mods 5. Deleting most of my profiles if storage was a problem.   Really not sure what to do next or if forge is just broken for ever for me now.
