I am trying to set up a command structure that would use /myMod myNewCommand Arguments

 

It seems that I could register 1 command class that uses /myMod as its sole alias and handle various subcommands during the execution of that single super command. An example of this follows:

package kmm.TestMod.Commands;

import net.minecraft.command.CommandBase;
import net.minecraft.command.CommandException;
import net.minecraft.command.ICommandSender;
import net.minecraft.server.MinecraftServer;
import net.minecraft.world.World;

/**
*
* @author Rinzler
*/
public class CommandTester extends CommandBase {

    @Override
    public String getCommandName() {
        return "myModName";
    }

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

    @Override
    public void execute(MinecraftServer server, ICommandSender sender, String[] args) throws CommandException {
        //
        World world = sender.getEntityWorld();
        
        if(world.isRemote) {
            //do stuff
        } else {
            if(args[0].equals("myNewCommand1")) {
                if(args.length > 1) {
                    //do myNewCommand1 plus Arguments
                } else {
                    //do stuff for myNewCommand1 no arguments
                }                
            }
            if(args[0].equals("myNewCommand2")) {
                if(args.length > 1) {
                    //do stuff for myNewCommand2 plus arguments
                } else {
                    //do stuff for myNewCommand2 no arguments
                }
            }
            //...more commands...
        }
        
        
    }
    

}

Is there a better way of doing this such that I can use /myMod as a command opener?

Extend 

CommandTreeBase

to create a command with sub-commands. Use 

CommandTreeBase#addSubcommand

to add a sub-command.

Exactly what I needed. Thanks! I have it working as I wanted now.

 

However, do I need to handle the help text for each subcommand? I can't seem to access it otherwise.

 

/help mymod gets the help text from the CommandTreeBase...but I can't seem to find the texts for the subcommands. I could just add a help argument branch for each subcommand...

 

edit: I am generating the help text by simply having

public void execute(MinecraftServer server, ICommandSender sender, String[] args) throws CommandException {
        

        if (args.length == 1 && args[0].equals("help")) {
            sender.addChatMessage(new TextComponentString(getCommandUsage(sender)));
        }
    }

in my subcommand execution. Seems to be working fine, although perhaps there is a better way.

For my mod's command, I added a 

help

sub-command that extends 

CommandHelp

, stores the instance of the base command and overrides 

CommandHelp#getCommandMap

and 

CommandHelp#getSortedPossibleCommands

to return values from the base command.

 

CommandTreeBase

provides a 

getCommandMap

method, but you have to implement 

getSortedPossibleCommands

yourself (

CommandHelp

calls 

ICommandManager#getPossibleCommands

and sorts the result).

 

You can see the base command here and the 

help

sub-command here.

 

Unfortunately this prints the vanilla header (which says 

/help

instead of 

/testmod3 help

), but you'd need to re-implement 

CommandHelp#execute

yourself to get around this.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

For the help files I am now using 

if (args.length == 1 && args[0].equals("help")) {
      throw new WrongUsageException("commands.testmod.command1.usage", new Object[0]);
      //TextComponentTranslation tct = new TextComponentTranslation("commands.testmod.command1.usage", new Object[0]);
      //sender.addChatMessage(tct);
}

 

Seems to work fine. Both the WrongUsageException and the TextComponentTranslation are working to get the string from the lang file.

Or rather: varargs is syntactic sugar that allows the compiler to automatically wrap the parameters in a 

new Object[]

for you. This includes 0 extra arguments.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

I like Syntactic Sugar. It reminds me of the flavor of my tears when sitting through Data Structures and Algorithms a couple years ago.

 

Trust me, I learned more about data structures and algorithms from modding Minecraft than I ever did in college.

      [1.18.2] Custom armor set extending DyeableArmorItem is dye-able, but not displaying

      By CatzRule81 · Posted

      I am not using hardcoded recipes, I'm using Vanilla's already existing code for leather armor dying. (via extending and implementing DyeableArmorItem / DyeableLeatherItem respectively) I have actually figured out that it's something to do with registering item colors to the ItemColors instance, but I'm trying to figure out where exactly in my mod's code I would be placing a call to the required event handler. Unfortunately the tutorial is criminally undescriptive. The most I've found is that it has to be done during client initialization. I'm currently trying to do the necessary setup via hijacking the item registry since trying to modify the item classes directly (via using SubscribeEvent in the item's constructor didn't work. Class so far: // mrrp mrow - mcmod item painter v1.0 - catzrule ch package catzadvitems.init; import net.minecraft.client.color.item.ItemColors; import net.minecraft.world.item.Item; import net.minecraftforge.registries.ObjectHolder; import net.minecraftforge.fml.event.lifecycle.FMLClientSetupEvent; import net.minecraftforge.fml.common.Mod; import net.minecraftforge.eventbus.api.SubscribeEvent; import net.minecraftforge.client.event.ColorHandlerEvent; import catzadvitems.item.DyeableWoolArmorItem; @Mod.EventBusSubscriber(bus = Mod.EventBusSubscriber.Bus.MOD) public class Painter { @ObjectHolder("cai:dyeable_wool_chestplate") public static final Item W_CHEST = null; @ObjectHolder("cai:dyeable_wool_leggings") public static final Item W_LEGS = null; @ObjectHolder("cai:dyeable_wool_boots") public static final Item W_SOCKS = null; public Painter() { // left blank, idk if forge throws a fit if constructors are missing, not taking the chance of it happening. } @SubscribeEvent public static void init(FMLClientSetupEvent event) { new Painter(); } @Mod.EventBusSubscriber private static class ForgeBusEvents { @SubscribeEvent public static void registerItemColors(ColorHandlerEvent.Item event) { ItemColors col = event.getItemColors(); col.register(DyeableUnderArmorItem::getItemDyedColor, W_CHEST, W_LEGS, W_SOCKS); //placeholder for other dye-able items here later.. } } } (for those wondering, i couldn't think of a creative wool helmet name)

      [1.18.2] Custom armor set extending DyeableArmorItem is dye-able, but not displaying

      By Shipwrecker · Posted

      Maybe there's something happening in the 'leather armor + dye' recipe itself that would be updating the held item texture?

      [1.20.1] Difficulty getting custom player model to render

      By Shipwrecker · Posted

      @SubscribeEvent public static void onRenderPlayer(RenderPlayerEvent.Pre e) { e.setCanceled(true); model.renderToBuffer(e.getPoseStack(), pBuffer, e.getPackedLight(), 0f, 0f, 0f, 0f, 0f); //ToaPlayerRenderer.render(); } Since getting the render method from a separate class is proving to be bit of a brick wall for me (but seems to be the solution in older versions of minecraft/forge) I've decided to try and pursue using the renderToBuffer method directly from the model itself. I've tried this route before but can't figure out what variables to feed it for the vertexConsumer and still can't seem to figure it out; if this is even a path to pursue.  The vanilla model files do not include any form of render methods, and seem to be fully constructed from their layer definitions? Their renderer files seem to take their layers which are used by the render method in the vanilla MobRenderer class. But for modded entities we @Override this function and don't have to feed the method variables because of that? I assume that the render method in the extended renderer takes the layer definitions from the renderer classes which take those from the model files. Or maybe instead of trying to use a render method I should be calling the super from the renderer like   new ToaPlayerRenderer(context, false); Except I'm not sure what I would provide for context? There's a context method in the vanilla EntityRendererProvider class which doesn't look especially helpful. I've been trying something like <e.getEntity(), model<e.getEntity()>> since that generally seems to be what is provided to the renderers for context, but I don't know if it's THE context I'm looking for? Especially since the method being called doesn't want to take this or variations of this.   In short; I feel like I'm super super close but I have to be missing something obvious? Maybe this insane inane ramble post will provide some insight into this puzzle?
