Apparently part of the craft table code checks to make sure there is actually a crafting table block in the world at the position called. Overriding that makes it work. Thanks Saxon564. public class ItemMatrix extends Item { public ItemMatrix() { super(); setMaxDamage(0); setMaxStackSize(1); setCreativeTab(Symbology.symbologyTab); setUnlocalizedName("rune_matrix"); } public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn) { playerIn.displayGui(new ItemMatrix.InterfaceCraftingTable(worldIn, playerIn.getPosition())); return itemStackIn; } public static class InterfaceCraftingTable extends BlockWorkbench.InterfaceCraftingTable implements IInteractionObject { private final World world; private final BlockPos position; public InterfaceCraftingTable(World worldIn, BlockPos pos) { super(worldIn, pos); this.world = worldIn; this.position = pos; } @Override public Container createContainer(InventoryPlayer playerInventory, EntityPlayer playerIn) { return new ContainerMatrixCrafter(playerInventory, this.world, this.position); } } }

I'm trying to add an item that acts as a portable crafting table and opens when held and right mouse is clicked. It almost works, the interface opens for about 1/10 of a second then closes. Eventually I want to get it to open a different GUI if shift is held but would like to get this part of it working first. If anyone could point out where I've gone wrong would be much appreciated. public class ItemMatrix extends Item { public ItemMatrix() { super(); setMaxDamage(0); setMaxStackSize(1); setCreativeTab(Symbology.symbologyTab); setUnlocalizedName("rune_matrix"); } public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn) { playerIn.displayGui(new BlockWorkbench.InterfaceCraftingTable(worldIn, playerIn.getPosition())); return itemStackIn; } }
