Player position in RenderGameOverlayEvent? [SOLVED]

My latest mini-mod practice project is to duplicate an old mod I saw in a let's play once, which would simply tell you on the Debug (F3) screen if you're standing in a slime chunk (I'll find this useful for my future slime-spawning mod since Rei's detection is wonky). I've sussed out how to add the text to the Debug screen, no problem. 

 

Where I'm getting caught up is getting my current position in order to do the calculations. Unlike the other events I've dealt with to date, world, position, and player don't seem to show up in the inheritance chain for RenderGameOverlayEvent. Please forgive me if I'm missing something obvious -- I've been working with a certain other language for several years that has sabotaged my brain's ability to properly map out scoping.

 

I figure that, if the answer to my question is "no", then I can "scrape" the X and Z coords out of the debug text lines and use them, but if there's a way to get posX and posZ straight, it'll be that much cleaner.

Most of those things (world, player...) are not needed to be sent in the event, as there exist only a single one for each client.  E.G each client only has a single world object, and is responsible for the position of a single player.  As such, these fields are accessible directly from the Minecraft class, in the form of  Minecraft.getMinecraft().thePlayer  and Minecraft.getMinecraft().theWorld  ..  These are a global reference can be accessed from anywhere (as long as it is client side, trying to use either on server side will crash with a ClassNotFound exception for Minecraft.class)

 

That gets you the 'controlling' client player, and the world he/she is currently residing in.  From there you can easily poll the player.posX/etc to get your positioning to calculate your chunks :)

That, my friend, is exactly what I needed. Thank you!

 

I still seem to have a glitch in my code somewhere, so I'm not done bughunting yet, but that was a big boost. Much obliged.

One of another problem you could encounter is that I don't think the data which says which chunks are slime chunks is available client sided...

Yeah, I was just coming back to post something to that effect. Using Minecraft.getMinecraft().theWorld will return a "Multiplayer" world, even if loaded single player. I'm pretty sure it's the same case for loading .thePlayer.

 

What I've ended up doing was trapping WorldEvent.Load and saving the world and the seed into static values for the mod, and that worked nicely. I've now got my "Slime Chunk: Yes/No" line on the debug screen.

 

Of course, I can't stop there. Now the wild hair has expanded so that I want a line of all spawnable monsters for the given location (I saw a let's play on YT with such a mod once, but it doesn't seem to exist for 1.5.2).

 

Bouncing around the code suggests I'm looking for IChunkProvider.getPossibleCreatures() but I'm still having some trouble sussing that one out. I'm not sure if I'm using the wrong positioning or the wrong provider, but it just keeps returning EntityEnderman and that's it. It's closer than I was yesterday, though.

 

Update: Or possibly I should take a look in WorldEvent.java which seems to obligingly provide a static PotentialSpawns class... Nerp... that seems to be for adding potential spawns...

      I need help with intellij lang file

      By BruhMoment · Posted

      yes the name is en_us.json and it is in resources -> assests -> testmod -> lang folders.  i have checked my code and am pretty confident that the code itself is correct.  i even tried loading the project in eclipse and it has the same problems, I think i will just rewatch the whole tutorial and will give an update on the situation.

      Hey man,    i have only been modding Minecraft for a few days but maybe I can help you. First of all make sure to follow every step of Kaupenjoe's tutorial, I found it to been very helpful and complete. The game uses the raw translation key for the item (in your case "item.testmod.alexandrite") if it can't find the correct lang file. Make sure it's name is "en_us.json" and it is saved under "ressources" -> "assets" -> "testmod".

      whenever I try to get this item to render into the game it appears with the not texture purple and black squares and calls itself by the lang translation file path instead of the name i gave it.   { "item.testmod.alexandrite": "Alexandrite" } this is the lang json file package net.Hurst.testmod.item; import net.Hurst.testmod.TestMod; import net.minecraft.world.item.Item; import net.minecraftforge.eventbus.api.IEventBus; import net.minecraftforge.registries.DeferredRegister; import net.minecraftforge.registries.ForgeRegistries; import net.minecraftforge.registries.RegistryObject; public class ModItems { public static final DeferredRegister<Item> ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, TestMod.MOD_ID); public static final RegistryObject<Item> ALEXANDRITE = ITEMS.register("alexandrite", () -> new Item(new Item.Properties())); public static void register(IEventBus eventBus){ ITEMS.register(eventBus); } } this is my ModItems.java file package net.Hurst.testmod; import com.mojang.logging.LogUtils; import net.Hurst.testmod.item.ModItems; import net.minecraft.world.item.CreativeModeTabs; import net.minecraftforge.api.distmarker.Dist; import net.minecraftforge.common.MinecraftForge; import net.minecraftforge.event.BuildCreativeModeTabContentsEvent; import net.minecraftforge.event.server.ServerStartingEvent; import net.minecraftforge.eventbus.api.IEventBus; import net.minecraftforge.eventbus.api.SubscribeEvent; import net.minecraftforge.fml.ModLoadingContext; import net.minecraftforge.fml.common.Mod; import net.minecraftforge.fml.config.ModConfig; import net.minecraftforge.fml.event.lifecycle.FMLClientSetupEvent; import net.minecraftforge.fml.event.lifecycle.FMLCommonSetupEvent; import net.minecraftforge.fml.javafmlmod.FMLJavaModLoadingContext; import org.slf4j.Logger; // The value here should match an entry in the META-INF/mods.toml file @Mod(TestMod.MOD_ID) public class TestMod { public static final String MOD_ID = "testmod"; private static final Logger LOGGER = LogUtils.getLogger(); public TestMod() { IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus(); modEventBus.addListener(this::commonSetup); ModItems.register(modEventBus); MinecraftForge.EVENT_BUS.register(this); modEventBus.addListener(this::addCreative); ModLoadingContext.get().registerConfig(ModConfig.Type.COMMON, Config.SPEC); } private void commonSetup(final FMLCommonSetupEvent event) { } // Add the example block item to the building blocks tab private void addCreative(BuildCreativeModeTabContentsEvent event) { if(event.getTabKey() == CreativeModeTabs.INGREDIENTS){ event.accept(ModItems.ALEXANDRITE); } } // You can use SubscribeEvent and let the Event Bus discover methods to call @SubscribeEvent public void onServerStarting(ServerStartingEvent event) { } // You can use EventBusSubscriber to automatically register all static methods in the class annotated with @SubscribeEvent @Mod.EventBusSubscriber(modid = MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void onClientSetup(FMLClientSetupEvent event) { } } } this is my TestMod.java file { "parent": "minecraft:item/generated", "textures": { "layer0": "testmod:item/generated" } } this is my model file for the item. I am using intellij 2025.1.2 with fdk 1.21 and java 21 I would appreciate the help.
