1.11.2 Custom Furnace

[Socratic_Phoenix]

So this is partially related to this thread I made:

But it's a mostly different topic, so yeah. Basically, I want to create a custom furnace that behaves exactly like the vanilla one, except for my custom recipes. I know I need to implement TileEntity, and all the gui stuff, but I have some questions:

 

What is tileentity exactly? What should I extend? TileEntity? TileEntityLockable?

How does TileEntity relate to my Block?

How do I save the inventory in the TileEntity?

How do I properly add the IItemHandler capability to my TileEntity?

How do I make the block face different ways?

How do I make the texture go from not burning to burning, and have pretty particles?

How do I handle timers? How do I figure out what items are fuel, and how long the fuel is supposed to burn?

How do I make the GUI have the pretty animations? (Moving arrow, burning fire).

A TileEntity is a class that extends (surprise) TileEntity.

How does TileEntity relate to my Block?

Override hasTileEntity and createTileEntity in your block class.

How do I save the inventory in the TileEntity?

By using an IItemHandler and writeToNBT on your TileEntity (you'll also need readFromNBT too, surprisingly enough).

Quote

How do I properly add the IItemHandler capability to my TileEntity?

By overriding hasCapability and getCapability on your TileEntity, checking if the reqrequested Capability is CapabilityItemHandler.ITEM_HANDLER_CAPABILITY, and if so, returning the IItemHandler field stored in your TE.

How do I make the block face different ways?

Same as you would without a TE. Using metadata.

Quote

How do I make the texture go from not burning to burning, and have pretty particles?

Using a boolean in your blockstate, then in your blockstate json file, using a different texture.

Particles: look at the vanilla furnace.

Quote

How do I handle timers?

MORE FIELDS, this time one that's an integer that you add (or subtract) from every tick.

Look at the vanilla furnace for a field called (curiously) "burnTime"

Quote

How do I figure out what items are fuel, and how long the fuel is supposed to burn?

Look at the vanilla furnace. There's an interface called IFuelHandler that is polled to find out.

Quote

How do I make the GUI have the pretty animations? (Moving arrow, burning fire).

Technically it doesn't animate.  It's just a progress bar that's handled by the client saying "the current burn time is 120, the maximum is 600.  I should display (120/600) pixels worth of this texture."

Yeah, but what, like is it. Conceptually I mean, what purpose does it serve in the game?

Should my block extend BlockContainer? I remember seeing somewhere that BlockContainer was evil and to stay away from it...

[Draco18s]

No. Do not extend BlockContainer.

Okay.

 

(Also, YAY there is much success, the furnace is block and it can switch on and off and it is orientable and has a nice texture... now for the actual furnace-y part, thanks for all the help!)

Does the TileEntity implement inventory or container, or should that be a seperate class store in the tile entity as a field?

 

Edit: and what interfaces should the TileEntity implement (if any)?

The TileEntity should only implement ITickable (not the client/sound one). And do not use IInventory on TEs, for the Container use SlotItemHandler instead of Slot.

Not always. Only if you need tick updates.

I assume a furnace needs tick updates though.... that's what I was referring to

Thanks to everyone for all their help! The furnace works perfectly! (Even with hoppers! It's like magic!)
