[WIP] Furnace in LUA

[lkjoel]

Ok, this is ridiculous. The furnace was implemented in C++ while it could have been easily made in LUA. So I'm spending a bit of time porting it over, and then it will be very easy to tweak ;)

Would it be like in Minecraft like when your cooking something it like turns on and gives a bit of light? And will it show you how much power the coal ect. has left?

Hmm. .. lkjoel, feel like expanding that furnace to, say, five states?

• Empty/out of fuel (the standard furnace texture)
• Fueled but idle (same thing but with some kind of "generic" fuel loaded into the bottom slot)
• Fueled and cooking: full, 2/3 and 1/3 fuel remaining, relative to the largest quantity possible of the fuel being used.

I'll make the necessary textures using data from my existing packs.

@LolManKuba, yeah, that's what I was thinking.
@VanessaE, Interesting idea... I'll try to do that too.

I should point out that what I envision for the three "active" states is the fire underneath burning at various intensities, and emitting a corresponding amount of light (which is a gradient drawn on the fireplace's front in my case; I've no opinion one way or another whether it should produce actual light in the game :-) ).

EDIT: expand suggestion to nine states: empty, four fueled-but-idle states (full, 3/4, 1/2, 1/4), and four fueled-and-cooking states (same levels). When the item to be smelted/cooked runs out, the furnace should switch from whatever fueled-and-cooking image is being used at that moment to the corresponding fueled-but-idle image, and vice-versa when new raw items are added. When fuel is added, removed, or burned, the displayed image should change to reflect the new state.

[lkjoel]

So nine states?

[VanessaE]

Yep! :-)

[LolManKuba]

lkjoel you're almost at your 400th post.

[lkjoel]

almost ;)

[Jordach]

yep.

Some time ago, there was a luafurnace in experimental mod:

https://github.com/celeron55/minetest/commits/master/games/minimal/mods/experimental/init.lua

If you look at the current version, there's still a commented block.
And if you look at old versions, seems like c55 wanted to give it a shot some time ago:

luafurnace with getting recipes was removed then itemdef patch was merged. but celeron promises think about, we remember this!! ^^

P.S.

kahrl:
Shortcomings

It's currently not possible to retrieve the result of a crafting operation from Lua. Therefore you can't rewrite the current furnaces in Lua.
