Greetings! I've been trying to figure out how I could add potion effects when an entity is on a certain custom block. I've been messing around with a lot of stuff specifically using the following method.

 

public void onEntityCollidedWithBlock(World par1World, int par2, int par3, int par4, Entity par5Entity)

    {

    }

 

I know how to make it so when someone collides with the block it damages them but it would be EXTREMELY helpful if someone could tell me how to add potion effects on collision with the block? Any help is greatly appreciated!

Thank for the reply! I'm glad you're trying to help. Anyways I've added this method into the block's class.

 

public void onEntityWalking(World par1World, int par2, int par3, int par4, Entity par5Entity)

    {

            par5Entity.addPotionEffect(new PotionEffect(Potion.blindness.id, 600, 4));

    }

 

Although it's wanting me to add a cast to par5Entity so it will look like this.

 

public void onEntityWalking(World par1World, int par2, int par3, int par4, Entity par5Entity)

    {

            ((Object) par5Entity).addPotionEffect(new PotionEffect(Potion.blindness.id, 600, 4));

    }

 

When I do this it comes up with a quick fix that says "Change method receiver cast". So when I click on the quick fix it does nothing. Any other ideas as to why this isn't working? I've been trying to figure this out for at least 3 hours and help is greatly appreciated!

Check if the entity variable is an instance of the EntityLivingBase class and if true, cast to it, not to Object.

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

I have just one small problem now. I am trying to give the entity the effect for one second an infinite amount of times as long as they're on the block. I've tried this.

 

public void onEntityWalking(World par1World, int par2, int par3, int par4, Entity par5Entity)

    {

for(int i = 0; i > 1; i++) {

            ((EntityLivingBase) par5Entity).addPotionEffect(new PotionEffect(Potion.blindness.id, par4));

            i = 0;

}

    }

 

But it's not going through the loop at all and I don't understand why. If I get rid of the loop and do this.

 

public void onEntityWalking(World par1World, int par2, int par3, int par4, Entity par5Entity)

    {

            ((EntityLivingBase) par5Entity).addPotionEffect(new PotionEffect(Potion.blindness.id, 2, 4));

    }

 

It adds the blindness effect for one second every time I step on the block which is what I want except I want it to happen infinitely as long as an entity is on the block. Any ideas? Perhaps there's a way to make it update every tick so that it goes through the code every tick? Any help is greatly appreciated!

    • 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.
