Execute Code on Block Update

Hello Guys

 

I'm currently developing a mod for forge, and I would like to execute some code whenever a block gets changed in the world (blockBreak, blockPlace, but also TileEntityChange etc.)

 

I have found out that there is a packet sent to the client if there is a blockUpdate.

(net.minecraft.network.packet.Packet53BlockChange.java)

 

Can I use/make a hook that executes my code when the packet is sent, or is there a better way to do this?

Also, will it execute if a TileEntity changes (e.g. the player takes something out of a chest)?

 

It would also be very nice, if this could be done server-side. (My code won't render anything)

Thanks for your reply.

 

Hooking into the breakBlock and setBlock event is a good idea, but I would also like to fire the event if a Tile Entity changes.

I think of it as a "blockChangeEvent" or "ID/Metadata/TileEntity-ChangeEvent".

 

All the data I need is the xyz-coordinate of the block.

Also, I want it to always fire, not only if a player does something.

There is no way you can detect if anything in any of those changes.

in theorie you could catch some changes by hooking markBlockForUpdate serverside, since modders have to call this to propagate the changes to the clients BUT it could also be called for no reason (and no change)

True words. But it would be unstable because you'd never know.

yeah, but in theory you could catch those, obviously you wouldn't be able to cancel those or get any relevent information out of it because it's different between every TE, but you could catch the "update" part

      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.
