1.11.2 Custom Crafting Table

[Socratic_Phoenix]

Okay, this should be fairly simple, but the research I've done so far hasn't been hugely helpful, and I see some things that say "always use this class" and then some tutorials implement other classes, so I'm not exactly sure what convention is here. I'm new-ish to forge modding as well, and this is my first project were I do anything more than generate a few ores (in this mod, I'll generate about 16 million of them). In short, I need to create a crafting table. Nothing fancy, in fact, it shouldn't be different than vanilla, other than gui name and block texture (and, of course, my custom recipes). I know that once I get the block actually in the world, with a gui and inventory, I can implement the recipe mechanic, so I'm going to focus on the first thing first.

 

So, my question is, how do I crafting table?

 

Does it need to be a TileEntity? If so, what kind? Just TileEntity? TileEntityLockable?

How do I provide the container (or gui screen or whatever it is)? I have an empty gui hander, but that's about it. (Also, what is the difference between Container and GuiScreen, how do they relate?)

How do I make the inventory work? How do I position the slots properly on the inventory when it's drawn (How does one even draw an inventory)?

How do I change set the title of the inventory ("Crafting Table" is vanilla, I want "Craftinium Table").

How do I open this inventory when the block is clicked?

How do I listen to the events from the inventory to check if the player has done recipe stuff?

Exactly what classes do I actually have to extend?

What. in. the. world. is. a. capability. (and how do I use it?) (Forge docs provided some context, but not much).

 

I understand that a lot of these questions could be answered with tutorials, but so far, I haven't found a single tut using capabilities, despite those being explicitly suggested in many of the forum topics I found, so I'm not sure what a "proper" implementation would look like. There's also the fact that I have no idea where I should start...

 

Thanks for any replies!

 

(I am using 1.11.2, Forge build #2228)

 

(For anyone who wants it, this is the github link to the package I'm putting all this code in, but at the moment there isn't anything for the table there yet...)

 

(Also, thanks for all the help I've received from the community so far! Very helpful! (also, also, I'm a forge noob, not a java noob, use whatever java lingo you deem necessary, but don't mention the evil that is bytecode instrumentation (which, side note, is surprisingly not difficult)))

No it does not need a TileEntity. You only need a TileEntity if you want to save the slots.

You return a Container in getServerGuiElement and a Gui in getClientGuiElement. The container is the Server sided object of a Gui and the Gui is the Client sided one GuiScreen extends Gui.

You add slots to it. When you add the Slots to the Container it will have it's position automatically made relative to the Gui and it will be measured in pixels. You use the Gui methods drawTexturedModelRect... to draw images on to the screen.

You should draw that using Minecraft#fontRenderer or this.fontRenderer in your Gui in the method drawGuiContainerForeground, and you should be using GuiContainer as your super class for your Gui.

Use EntityPlayer#openGui in Block#onBlockActivated

This would take way to long for me to explain, but I suggest looking in the vanilla Crafting Table Container.

Capabilities are basically does this Object have an Inventory or IItemHandler Capability? If so give it to me and let me access it from a particular direction.

As stated above GuiContainer or the Crafting Tables Gui if you can salvage some of it's methods and Container or the Crafting Tables Container once again if you can salvage anything from it.

I don't (at least, not until I make the furnace), so should the crafting table just extend Block and override the onclick/interact/whatever method?

[Animefan8888]

Extend Block and override Block#onBlockActivated

Slot takes an inventory... do I have to implement an IInventory for the crafting grid?

You should use a InventoryCrafting look in ContainerWorkbench.

Thanks so much for your help! It works perfectly! Now, should I create a separate thread with similar questions about furnaces (and tile entities and capabilities)? Or should I continue the discussion here? (Probably a new thread...)

[Animefan8888]

It should be a new Thread as it is a completely different subject than what the title suggests.
