Hello!

 

I begin developing a Minecraft mod, where you can find lead and uranium ores. When you touch the uranium (after you mine it), it applies poison effect on you, but i want a similar effect, but only with the ores:

 

When I get close, i want it apply poison on player. How to do  it? I tried similar things (google), but nothing works. thanks for any help!

I try to register the event:

 

 

    @EventHandler

    public void init(FMLInitializationEvent e) {

        this.proxy.init(e);

    // the majority of events use the MinecraftForge event bus:

        MinecraftForge.EVENT_BUS.register(new CheckTick());

    }

 

 

 

My Code in Player Tick so far:

 

 

package com.example.examplemod;

 

import com.example.examplemod.blocks.ModBlocks;

 

import net.minecraft.block.Block;

import net.minecraft.entity.Entity;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.potion.Potion;

import net.minecraft.potion.PotionEffect;

import net.minecraft.util.BlockPos;

import net.minecraft.world.World;

import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

import net.minecraftforge.fml.common.gameevent.TickEvent.PlayerTickEvent;

import net.minecraftforge.fml.relauncher.Side;

import net.minecraftforge.fml.relauncher.SideOnly;

 

// RenderTick is client side only, so we can place the SideOnly annotation here if we want:

@SideOnly(Side.CLIENT)

public class CheckTick {

//we only need one method here, and you can name it whatever you want, but

//I like to name it according to the tick to which I am listening:

@SubscribeEvent

public void onCheckTick(PlayerTickEvent event, Entity entity, World world) {

EntityPlayer player = (EntityPlayer) entity;

//now you can do whatever you want during each render tick, such as rotate the player's view

Block checkblock=world.getBlockState(new BlockPos(player.posX,player.posY+1,player.posZ)).getBlock();

 

if (checkblock == ModBlocks.tutorialBlock2){

player.addPotionEffect((new PotionEffect(Potion.poison.getId(), 100, 5)));

}

}

}

 

 

 

I try to get the block under the player.Y, and check is that my custom ore. Is this right?

Thanks for your advice, but I think my problem is not related to lack of knowledge of java, but lack of knowledge of modding. I do all the beginner tutorial (from item create to structures), but now I try to do something that I never tried before, and maybe never will, and there is not a single tutorial for this. Not to mention that nearly all tutorial outdated (pre-1.8).  You help me a lot - and thank you for that :)

If you knew Java this would be your thought process:

 

  1. [*]Me: "You get world and player from the event".

[*]You: Ok, let me check that. Ok, my event is "PlayerTickEvent". Let me look at that class. Oh look, there is is:

public final EntityPlayer player;

- that's probably what he meant.

[*]Problem solved!

[*]?

[*]Profit.

I knew java, but for a really short time, and just because I want develop mod, I not say anithing else. But now I look more into the minecraft classes and find every solution (I not use eclipse too much before too), and now i finish the mod. After all, relly really thanks for your patience and help to finish the mod! :)

    • Thanks. But I thought they would help me decide on the code. (((    As a result, I figured it out myself.   private static final DeferredRegister<Item> ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, MODID); public static final RegistryObject<BlockItem> MyBlockItem = ITEMS.register("mysuperblockreg", () -> new BlockItem(testBlock, new Item.Properties().tab(CreativeModeTab.TAB_BUILDING_BLOCKS)));

    • Your createBodyLayer creates a HumanoidModel. Then it gets the body child and adds new parts to it (why you do this instead of overwriting the existing body parts I do not know). When getting the childs later you try to get the body parts directly, but they are children of the "body" child.
    • I am finding the code difficult to read. Can anyone give me an example of a block, similar to sand, that, when placed, turns into and entity, goes up one block, then turns back into a block?
