Custom Furnace - 2 items, combined fuel

[OwnAgePau]

Hi there,i am making a cool mod and i was trying out this GUI thing, so i got all the files setup and it worked using my custom made GUI, but when i tried adding in a new slot it would crash on opening so i tried some things but i can't get it to work properly, also i haven't really found anyone explaining on how to do such thing.

 

So without the custom slots it worked, well I'm using Forge v7.7.1.611, MCP 7.44

And these are my files:

 

mod_Ores:

 

 

package Mod_Ores;

@Mod(modid="myOresMod", name="Extra Ores Mod", version="1.1.2")
@NetworkMod(clientSideRequired = true, serverSideRequired = false, clientPacketHandlerSpec =
@SidedPacketHandler(channels = {"mod_Ores" }, packetHandler = ClientPacketHandler.class),
serverPacketHandlerSpec =
@SidedPacketHandler(channels = {"mod_Ores" }, packetHandler = ServerPacketHandler.class))
public class mod_Ores
{
@Instance("myOresMod") // instance
    public static mod_Ores instance;
private IGuiHandlerCustom guiHandler = new IGuiHandlerCustom();
@Init
public void load(FMLInitializationEvent ev)
{		
//Other Registering	
	ModLoader.registerTileEntity(TileEntityGemcutter.class, "Gemcutter"); //TileEntity Registry
	NetworkRegistry.instance().registerGuiHandler(this, guiHandler); //GUI Registery
}
}

So i hope that someone there is willing to help me find out how to do something like that!

Hi there,i am making a cool mod and i was trying out this GUI thing, so i got all the files setup and it worked using my custom made GUI, but when i tried adding in a new slot it would crash on opening so i tried some things but i can't get it to work properly, also i haven't really found anyone explaining on how to do such thing.

 

So without the custom slots it worked, well I'm using Forge v7.7.1.611, MCP 7.44

And these are my files:

 

mod_Ores:

 

 

package Mod_Ores;

@Mod(modid="myOresMod", name="Extra Ores Mod", version="1.1.2")
@NetworkMod(clientSideRequired = true, serverSideRequired = false, clientPacketHandlerSpec =
@SidedPacketHandler(channels = {"mod_Ores" }, packetHandler = ClientPacketHandler.class),
serverPacketHandlerSpec =
@SidedPacketHandler(channels = {"mod_Ores" }, packetHandler = ServerPacketHandler.class))
public class mod_Ores
{
@Instance("myOresMod") // instance
    public static mod_Ores instance;
private IGuiHandlerCustom guiHandler = new IGuiHandlerCustom();
@Init
public void load(FMLInitializationEvent ev)
{		
//Other Registering	
	ModLoader.registerTileEntity(TileEntityGemcutter.class, "Gemcutter"); //TileEntity Registry
	NetworkRegistry.instance().registerGuiHandler(this, guiHandler); //GUI Registery

So i hope that someone there is willing to help me find out how to do something like that!

well what does the crash log say if it's still crashing?

or if it's not crashing but not working properly as you suggest then what do you mean by not working properly?

Try changing "gemcutterItemStacks[3] " to "gemcutterItemStacks[4]".

Well it is not crashing, but when i have it to work "properly" i would have 2 fuels, but i think i can also do the almost same thing when adding a 2e input slot instead, so that you have 1 fuel to craft 2 different items , but do you have any idea how to do such?

 

Try changing "gemcutterItemStacks[3] " to "gemcutterItemStacks[4]".

 

Jeah i've been looking for the row where it sayd that cause i knew i had to but thanks anyway, i must have looked over it a couple of times. - found it
