Does the furnace work in the current version of minetest master?

I have put both coal and wood in it, but get an "out of fuel" message from the furnace anyway.

But it works in the minimal game version

Then that means the issue is with your copy of minetest_game. Get a new copy!

Hm. The furnaces look different too between the minimal and regular versions.

The furnaces messages are not correctly if you just put fuel in it (IIRC). If you put something to cook/smelt in it it will change.

I tried to make coal out of wood when I got this error. Now it works - I think what solved it was changing to the stable version of minetest-game

You cant make coal out of wood.

I just did!

hey, I'm having same problem, "furnace out of fuel" using stable release version 0.4.3
the ubuntu default which is 0.3 something has it working, but can't make doors.

i didn't see any setting to change it to "minimal version" though ya, the graphics are much improved from 0.3.x and there is sound, so can probably update that in the website description.

edit to add: oh okay found the minimal, it's the developer version k.

Hey, so I tested the latest version 0.4.4-dev minetest-game and same problem, furnace out of fuel. both in the minimal, and the game version, same thing for 0.4.3 neither of them have working furnaces.

The furnace will show "furnace out of fuel" even if fuel is in it (like PilzAdam said above) it will only change to "Furnace active: %" after you put something into smelt/cook.

So I managed to get it working in the minimal,
in the game verison doesn't accept anything,
even if there is something to cook (wood -> ),
it's always out of fuel.

been looking at the source files attempting to identify the issue,
seems like it may be that CRAFT_METHOD_FUEL doesn't have a return statement in craftdef.cpp
wheras CRAFT_METHOD_COOKING does have a return result lines, so would explain why cooking is working.

craftdef.cpp
else if(name == "fuel")
{
def = new CraftDefinitionFuel;
}
.
.
.
CraftInput CraftDefinitionFuel::getInput(const CraftOutput &output, IGameDef *gamedef) const
{
std::vector<std::string> rec;
rec.push_back(recipe);
return CraftInput(CRAFT_METHOD_COOKING,(int)burntime,craftGetItems(rec,gamedef));
}
craftdef.cpp te quote be

I'd think that it should say CRAFT_METHOD_FUEL

anyways if CRAFT_METHOD_FUEL isn't set somewhere, then the check for fuel will always return false

craftdef.cpp
bool CraftDefinitionFuel::check(const CraftInput &input, IGameDef *gamedef) const
{
if(input.method != CRAFT_METHOD_FUEL)
return false;
craftdef.cpp

as it is now, the above line 819 is the only mention of CRAFT_METHOD_FUEL in craftdef.cpp, so it makes sense that it's always false.

oh actually i'm not sure, it doesn't seem to make a different about the line now that I double checked, i'll do a full recompile see if it makes a difference.

---
yep there is absolutely no difference but w/e guess it couldn't hurt to patch the typo.
it works same way in minimal, and doesn't work in the game version just the same.

here is the patch anyways

----------------------------------

Okay, I found a rather brutish though simple solution for making furnace work in minetest_game by copying the minmal's default/init.lua overtop of the game's.
so the issue is within init.lua next step is to track it down.

-----

So i subdivided init.lua to make it more manageable into a number of files.
found the issue is in cook.lua

as Omnistudent refered, the problem was in lack of more
cook.lua

minetest.register_craft({
type = "cooking",
output = "default:coal_lump",
recipe = "default:tree",
})

cook.lua

anyways, guess i'll make a tarball of the fix..

Okay is solved,

as Omnistudent refered, the problem was in lack of a function in cooking section
