FOSS gamedev and creative worlds

Technic-based electric arc furnaces, crucible materials, and non-renewable "finite-liquids" like molten metals.

Mundane waste material can be melted down and refined for steel, copper, gold, and glass.

Crafting guides and information can be found on Github: https://github.com/yzziizzy/minetest_forge





All code and textures are WTFPL. Seriously, I don't care what you do.

Dependencies:
Default, Technic

Update (2016 / 08 /14) [v. 0.2]

• Cooling is now fixed.
• The electrode uses as much power as the system gives it, like a battery box. The more energy the faster ores are melted.
• Liquids have density and stratify accordingly.
• Ores take different amounts of energy to melt.
• Bug fixes for fluid dynamics

Looks great, I'll try it out when I can. I like how it requires building a large structure for the machine as an emergent effect of the molten ore mechanics, as opposed to just checking the existence of a pre-defined structure.

Line 612 of init.lua: melts_to is nil.

EDIT: Another bug: the electrode reports no network, even when it's connected and working.
EDIT2: get_node_group is deprecated in favor of get_item_group, which works for any item.
EDIT3: Not sure if you intended this, but this has good grief potential in melting hills.
EDIT4: Though not as much as I thought, because originally I thought melted ore would melt other meltable ores.
EDIT5: I think you should make the flowing liquid spread only 2 nodes, since that's how far the sources can spread.

Very nice mod

I'm seeing a big forge being build :)

0: Fixed.
1: Fixed, I think. Technic can be a bit finicky.
2: Thanks for the info, fixed.
3/4: Things only melt when near the electrode. The destructive abm (which had the bug) is currently primitive and could cause some grief. I will be improving the melting and cooling calculations soon which will make such griefing impractical without vast amounts of power.
5: Fixed. It used to only spread two nodes but that setting was accidentally lost in an early refactor.

The zip link has been updated.


Thanks for your feedback :)

I always wanted such a mod :D
Edit:

• alloying would be nice
• why does it use lv?
• it should use more energy, with a normal furnace it would need 300, but you smelt whole blocks

I've been flipping back and forth on how that should work. On one hand it's nice to separate the metals by density, on the other hand it would be nice to make alloys. I want to figure out a good mechanic to allow both. Ideas?

Because real arc furnaces use (relatively) low voltage with very high amperage. The idea is you would have to use a nuclear reactor down-converted to LV in order to get enough EU's to run a large forge. I already jacked up the energy requirements once, will jack them up substantially more in the next version.

maybe just allow horizontal alloying

yes! this:

Nice mod! Though I think it might be a bit too easy to make an infinite metal machine with this, a geothermal generator, and a cobblestone generator. Instead of yielding whole blocks, you could make new nodes that look like slag but have the target mineral embedded in it ("slag with iron," "slag with copper," etc.), which can yield however many lumps you want.

Railroad crucible cars are on the list, dunno when I will get to them. Pull requests are welcome :)
If only Voxel Area Objects existed...

In truth the forge mod is designed to go with my yet-unreleased 3d-perlin noise based geology mapgen. Notice the strange stone nodes my original screenshot. ;) The idea is you will have to feed it metal-bearing ores. Regular cobble wouldn't yield anything, except perhaps at extreme chance like slag.

What about 1/8th slabs for the metal?

Nice, bring in the new nodes then :P

I was starting to feel guilty, on the one hand I don't want to spend the entire time melting, chopping slag, melting chopping slag :)
on the other hand, making a lot of metal from dirt or cobble seemed a bit cheaty :P
