Hello Everybody!

 

I'm having issues getting a TileEntity from using:

worldObj.getTileEntity(xCoord, yCoord, zCoord);

 

I just get null pointer exceptions...

-Using try/catch solved the crash but doesn't fix the issue...

 

Below is the TileEntity Class:

 

	
package com.example.examplemod.entity;

import net.minecraft.tileentity.TileEntity;

public class TileMultiBlock extends TileEntity {

public TileMultiBlock(int x, int y, int z) {
	System.out.println(String.format("X: %d y: %d Z: %d", x, y, z)); // Returns block's co-ordinates
	System.out.println(String.format("X: %d y: %d Z: %d", xCoord, yCoord, zCoord)); // Returns 0, 0, 0

	try {
		TileEntity TE = worldObj.getTileEntity(xCoord, yCoord, zCoord);
		System.out.println(TE.blockMetadata);
	} catch (Exception e) {
		e.printStackTrace();
	}
	//updateEntity();

	//TileEntity tileEnt2 = worldObj.getTileEntity(x, y, z);
}

 

And below here is the Block Class:

I have it passing it's co-ordinates to the TileEntity..

 

package com.example.examplemod.blocks;

import com.example.examplemod.entity.TileMultiBlock;
import com.example.examplemod.misc.CreativeTab;

import net.minecraft.block.BlockContainer;
import net.minecraft.block.material.Material;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;

public class BlockMainBlock extends BlockContainer {
int x;
int y;
int z;

public BlockMainBlock(Material mat) {
	super(mat);
	setBlockName("mainBlock");
	setCreativeTab(CreativeTab.tabSlime);
}

@Override
public void onBlockAdded(World world, int x, int y, int z) {
	this.x = x;
	this.y = y;
	this.z = z;
}

@Override
public TileEntity createNewTileEntity(World p_149915_1_, int p_149915_2_) {

	return new TileMultiBlock(x, y, z);
}	
}

 

Thanks for all your troubles!

a) Alright done

b) When I use xCoord, yCoord, zCoord. Problem is they always are 0, 0, 0

c) Ahh never knew that

 

So how could I get xCoord, yCoord, zCoord not to be 0, 0, 0? 

 

 

 

Why are you want to get a TileEntity in your TileEntity class? Thats stupid!

Your tile entity is already defined with "this."!!!

Your case: this.blockMetadata;

 

If you  create a new TE for your block the cordinates are already "connected" together!

BUT be careful TE can be null and crash the game!

 

Ah I see at what you getting at @Kriki98, @diesieben07

I also figured out why it was returning 0, 0, 0. I shouldn't put that in the constructor but in the updateEntity() method.

 

Thanks for all your help!
