[1.12.2] [Solved] Set Minecraft Vanilla block to my own custom block

Toastyman23 · July 26, 2018

I'm making a mod that adds a broom to Minecraft so I can learn how things work. I basically just want certain blocks to get dirty over time, and a right click from my broom will set them back to normal.

The way I want to do this is by setting every plank block in a certain radius(maybe 50 blocks) to my own custom block, which will just be the plank but dirtier. Then I'll make it so if the block is activated with the broom in hand, it'll set the block back to the default plank texture. What I haven't figured out is how exactly you set blocks to other blocks. Here's what I've tried so far.

package toastyman231.broommodandmore.util.handlers;

import net.minecraft.block.Block;
import net.minecraft.block.state.IBlockState;
//import net.minecraft.client.Minecraft;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.profiler.Profiler;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import net.minecraft.world.WorldProvider;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.storage.ISaveHandler;
import net.minecraft.world.storage.WorldInfo;
import net.minecraftforge.fml.common.Mod.EventBusSubscriber;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.common.gameevent.TickEvent;
import toastyman231.broommodandmore.init.ModBlocks;

@EventBusSubscriber
public class TickHandler extends World
{
	EntityPlayer player;
	BlockPos pos = new BlockPos(player.posX, player.posY, player.posZ);
	Block blk = ModBlocks.TEST_BLOCK;
	BlockPos pos1 = new BlockPos(pos.getX()+2, pos.getY(), pos.getZ());
	IBlockState state = blk.getDefaultState();
	
	protected TickHandler(ISaveHandler saveHandlerIn, WorldInfo info, WorldProvider providerIn, Profiler profilerIn,
			boolean client) 
	{
		super(saveHandlerIn, info, providerIn, profilerIn, client);
	}
	
	@SubscribeEvent
	 public void onWorldTick(TickEvent.WorldTickEvent event)
	 {
		pos = new BlockPos(player.posX, player.posY, player.posZ);
		
		destroyBlock(pos, true);
		setBlockState(pos1, state);
	 }

	@Override
	protected IChunkProvider createChunkProvider() {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	protected boolean isChunkLoaded(int x, int z, boolean allowEmpty) {
		// TODO Auto-generated method stub
		return false;
	}
}

So far this doesn't do anything, and I don't know if it's because I set up the tick event wrong or if setBlockState just isn't how you replace blocks or what. What exactly am I doing wrong here, and how do I get every block of a certain type within 50 blocks of the player and set them to another block?

Why on earth are you extending World?

I'm extending World so I can use setBlockState easier.

As for the rest, thanks a bunch, I'll update with the result once I make the changes.

That's not how that works.

I tried just importing World and calling it that way, but it didn't work until I put extends World back. If I'm doing it wrong, how am I supposed to be doing it?

Toastyman23 · July 26, 2018

Okay so I've been working on the mod for a little bit and I've hit another wall. I did what diesieben07 said and switched to PlayerTickEvent and checked TickEvent.Phase, however it still does nothing upon running. Here's the new code:

package toastyman231.broommodandmore.util.handlers;

	IBlockState state = blk.getDefaultState();
	
	protected TickHandler(ISaveHandler saveHandlerIn, WorldInfo info, WorldProvider providerIn, Profiler profilerIn,
			boolean client) 
	{
		super(saveHandlerIn, info, providerIn, profilerIn, client);
	}
	
	public void ReplaceBlocks(BlockPos loc1, BlockPos loc2) 
	{
		BlockPos position = (BlockPos) BlockPos.getAllInBox(loc1, loc2);
		List<BlockPos> poses = new ArrayList<BlockPos>();
		poses.add(position);
		
		int index = 0;
		for(BlockPos blockPos : poses)
		{
			if(Minecraft.getMinecraft().world.getBlockState(poses.get(index)) == Blocks.GRASS.getBlockState())
			{
				setBlockState((BlockPos) poses.get(index), state);
                index++;
			}
		}
	}

	@SubscribeEvent
	 public void onPlayerTick(TickEvent.PlayerTickEvent event) /*throws InterruptedException*/
	 {
		if(event.phase == TickEvent.Phase.START)
		{
			EntityPlayer player = event.player;
			
			//TimeUnit.SECONDS.sleep(30);
			BlockPos pos = new BlockPos(player.posX, player.posY, player.posZ);
			BlockPos pos1 = new BlockPos(pos.getX()-24, pos.getY()-24, pos.getZ()-24);
			BlockPos pos2 = new BlockPos(pos.getX()+25, pos.getY()+25, pos.getZ()+25);
			
			ReplaceBlocks(pos1, pos2);
		}
	 }

	@Override
	protected IChunkProvider createChunkProvider() {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	protected boolean isChunkLoaded(int x, int z, boolean allowEmpty) {
		// TODO Auto-generated method stub
		return false;
	}
}

What did I do wrong this time folks?

You're still extending World. Of course shit don't work.

Why are you getting the client world? Use the world given to you by the event (doesn't have one, get the event's player's world).

How do I do it without extending World then? I tried just setting a reference but it kept trying to tell me that TickHandler didn't have a function called setBlockState. I did it once before I made this thread too, without any issues, but now it doesn't work.

setBlockState is a method of world, it is also public so therefore you can call it from an instance of World. Which all Entities have a public instance. Also how well do you know Java?

I took a class in Java but I'm more experienced with C# and Unity.

Turns out I was just being stupid and was using the wrong type of reference. I have it error free without extending World now, but it still doesn't work.

You never set your world variable to anything, and you expected that to work?

I figured it would inherit what it needed from World, but I guess not. What am I supposed to set it to? I tried World worldRef = new World(); but it just says it can't instantiate the type World because World is an abstract class. What exactly am I supposed to be doing here?

The PlayerTickEvent has a reference to the EntityPlayer as you know. All Entities including the player have a reference to the world they are in.

So then the player I'm passing in should work, right? I removed the reference to World and changed the setBlockState line to use the world from event.player. However it still doesn't work.

Why are you casting an Iterable to BlockPos, this shoudn't even compile.

That cycles through every BlockPos stored in the list of BlockPoses poses.

Use the Iterable returned by the method instead of the list you have created.

Why do you have the index variable just use the one created in the loop that is already a BlockPos.
