Hi! I have a block called the portal block which contains a tile entity. However, the tile entity does not appear to exist. When I run the code that gets the tile entity, it returns null even though I am certain I got all of the code for spawning one right. Here is my code:

Base mod code (relating to the tile entity)

GameRegistry.registerTileEntity(PortalBlockTileEntity.class, "portalBlockEntity");

Block code
package com.unlocked.stuff_things.blocks;

import com.unlocked.stuff_things.StuffAndThingsMod;

import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.AxisAlignedBB;
import net.minecraft.world.World;

public class PortalBlock extends Block {

PortalBlockTileEntity t;

}

this.setBlockName("portal_block_trans");
this.setBlockTextureName("stuffthings:portal_block_trans");
}
}

public void onBlockPlacedBy(World world, int x, int y, int z, EntityLivingBase player, ItemStack stack){

return AxisAlignedBB.getBoundingBox((float)i + f, j, (float)k + f, (float)(i + 1) - f, (float)(j + 1) - f, (float)(k + 1) - f);
}

public void SetX(double x, World world){

Tile entity code

entity.setPosition(this.x, this.y, this.z);
entity.fallDistance = 0f;

if (world.getBlock(i, j, k) == StuffAndThingsMod.portalBlockTrans && entity.dimension != this.dimension){
entity.travelToDimension(this.dimension);
}
}
return entity;
}

@Override
public void readFromNBT(NBTTagCompound nbt)

super.readFromNBT(nbt);
this.x = nbt.getDouble("x");
this.y = nbt.getDouble("y");

public double GetX(){

}

public double GetY(){

public int GetDimension(){

@Override

nbt.setDouble("x", x);
nbt.setDouble("y", y);
nbt.setDouble("z", z);
nbt.setInteger("dim", dimension);
nbt.setBoolean("set", set);
}

}

Thanks for any help.
