tile entity block not working

[Mystic4pheonix]

You're not calling this method anywhere. The tile wasn't even registered, also you should probably update forge since that GameRegistry#registerTileEntity method was deprecated... you should use the one with ResourceLocation parameter instead of string... or just make the string be like this "modid:tilename"

where do I register guis

 

[MonolinkTV]

I would need more info you mean register them as a single you do it in your preInit

		NetworkRegistry.INSTANCE.registerGuiHandler(Main.instance, new GuiHandler());

Of course, you would need a GUIHandler

package com.mrf.infinityweapons.util.handlers;

import com.mrf.infinityweapons.container.Container_Lava_Compressor;
import com.mrf.infinityweapons.gui.GUI_Lava_Compressor;
import com.mrf.infinityweapons.tileentitys.TileEntity_Lava_Compressor;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import net.minecraftforge.fml.common.network.IGuiHandler;

public class GuiHandler implements IGuiHandler {

    public static final int GUINAMEHERE = 0;
    
    @Override
    public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
        if (ID == GUINAMEHERE) {
            return new CONTAINERCLASSHERE(player.inventory, (YourTileEntityHere) world.getTileEntity(new BlockPos(x, y, z)));
        }
        return null;
    }

    @Override
    public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
        if (ID == GUINAMEHERE) {
            return new GUICLASSHERE(player.inventory, (YourTileEntityHere) world.getTileEntity(new BlockPos(x, y, z)));
        }
        return null;
    }
    
}

Just fill in the blanks 

Hope this helped!
