Creating a custom workbench

[winnetrie]

I want for example to create a birch workbench. What do i need to do to make this work?

This i think i need:

-guihandler class

-guicontainer

-container class

-block class

I have these 4 made, but it isn't working right now. I also haven't found out where or how to add textures to the block. I guess it's not via .json blockstates!

So the block is there ingame (pink/black squared for the moment) when right clicking you see a flashing of the gui. It looks like it is opening and closing almost instantly.

 

guihandler:

public class ModGuiHandler implements IGuiHandler{
	
	public static final int MOD_WORKBENCH_GUI = 0;

	@Override
	public Object getServerGuiElement(int ID, EntityPlayer player, World world,
			int x, int y, int z) {
		switch (ID){
		case MOD_WORKBENCH_GUI: {
			return new EntityWorkbench(player.inventory, world, new BlockPos(x, y, z));
			}
		
		}
		
		return null;
	}

	@Override
	public Object getClientGuiElement(int ID, EntityPlayer player, World world,
			int x, int y, int z) {
		switch (ID){
		case MOD_WORKBENCH_GUI: {
			return new ModGuiCrafting(player.inventory, world);
			}
		}
		
		return null;
	}

}

 

container:

public class ModContainerWorkbench extends Container{
	
	/** The crafting matrix inventory (3x3). */
    public InventoryCrafting craftMatrix = new InventoryCrafting(this, 3, 3);
    public IInventory craftResult = new InventoryCraftResult();
    private final World world;
    /** Position of the workbench */
    private final BlockPos pos;

    public ModContainerWorkbench(InventoryPlayer playerInventory, World worldIn, BlockPos posIn)

I have these 4 made, but it isn't working right now. I also haven't found out where or how to add textures to the block. I guess it's not via .json blockstates!

Yes it is! Take a look at the forge blockstate docs.

What is EntityWorkbench? You should return your Container in this method.

playerIn.displayGui(new BlockWorkbench.InterfaceCraftingTable(worldIn, pos));

This is the vanilla method which doesn't refer to your GuiHandler at all. You need to use player#openGui(Object modInstance, int guiID, World world, int x, int y, int z). That will call the appropriate-side methods from your GUI handler to get the correct container/GUI.

Ah yes ofc i changed it to

playerIn.openGui(Tem.instance, ModGuiHandler.MOD_WORKBENCH_GUI, worldIn, pos.getX(), pos.getY(), pos.getZ());

Works fine now!

Where and how do i apply textures to the block now?

nvm i didn't find an workbench.json in the minecraft blockstates before, but it appears to be called craftingtable.....

The easiest way is using the forge blockstates format.
