Hey all I made two Guis and they work how i want . But if i try to handle both of them with the IGuiHandler  using two different gui handlers my game crashes when i open them.But if i just use one gui handler for one gui that gui works.But obviously i want both to work. I have spent a lot hours now but i'm sure the answer is just staring me in the face.Oh and yes i have registered them in main mod file.

See that spot that says "switch(ID)"?

 

That's where you add more IDs.

I tryed mutiple cases with one gui handler but they both crashed when i did i take it you want some kind of crash report or the code from that?

Here's mine, works fine.

 

package com.draco18s.ores;

import com.draco18s.ores.client.*;
import com.draco18s.ores.entities.*;
import com.draco18s.ores.inventory.*;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;
import cpw.mods.fml.common.network.IGuiHandler;

public class GuiHandler implements IGuiHandler {
@Override
    public Object getServerGuiElement(int id, EntityPlayer player, World world, int x, int y, int z) {
	//System.out.println("This occurrs (client)" + id);
	if(id == 0) {
		TileEntity tileEntity = world.getTileEntity(x, y, z);
		if(tileEntity instanceof TileEntitySifter){
			return new ContainerSifter(player.inventory, (TileEntitySifter) tileEntity);
		}
	}
	else if(id == 1) {
		TileEntity tileEntity = world.getTileEntity(x, y, z);
		if(tileEntity instanceof TileEntitySluice){
			System.out.println("Returning new Container");
			return new ContainerSluice(player.inventory, (TileEntitySluice) tileEntity);
		}
	}
	return null;
    }

    //returns an instance of the Gui you made earlier
    @Override
    public Object getClientGuiElement(int id, EntityPlayer player, World world, int x, int y, int z) {
	//System.out.println("This occurrs (server)" + id);
    	if(id == 0) {
		TileEntity tileEntity = world.getTileEntity(x, y, z);
		if(tileEntity instanceof TileEntitySifter){
			return new GuiContainerSifter(player.inventory, (TileEntitySifter) tileEntity);
		}
    	}
    	else if(id == 1) {
		TileEntity tileEntity = world.getTileEntity(x, y, z);
		if(tileEntity instanceof TileEntitySluice){
			System.out.println("Returning new GUIcontainer");
			return new GuiContainerSluice(player.inventory, (TileEntitySluice) tileEntity);
		}
    	}
	return null;
    }

}

Hmm i took you code and swapped out the relative parts and changed my gui ids to the same as yours but i still get a crash this is what my gui handler looks like now

You have this on line 25:

return new ContainerMicrobeExtractor(player.inventory, (TileEntityMicrobeExtractor) tileEntity);

And this on line 42:

return new ContainerMicrobeExtractor(player.inventory, (TileEntityMicrobeExtractor) tileEntity);

 

I have this:

return new ContainerSifter(player.inventory, (TileEntitySifter) tileEntity);

and this:

return new GuiContainerSifter(player.inventory, (TileEntitySifter) tileEntity);

 

Spot the difference.

wow i was always bad at those games as a kid. It actually took me a while to see what you were getting at but now i see Guis for client Containers for server Its all working now thank you for you help even when i was being incompetent.
