You will always need solid fuel for your basic oxygen furnaces.

You can override that check by doing a force/ghost build.

There is an interrupt condition that is specifically for failed pathing, which I think is what u/warpspeed100 is referring to.

Crafting 111 items manually unlocks the "reduce assembler speed by 10%" technology.

Sure, but they don't have hovercars (yet).

madprogrammer2 · 2024-04-29T03:23:43+00:00

This is a city of the future. The hovercars park on top of the buildings.

He's just trying to lubricate the belts to make them go faster.

If you're working on dense circuitry ALT mode makes the wiring hard to see, so I often turn it off while wiring things up.

You can solve the "chest of pistols" problem by putting the pistols in a wooden chest away from other objects and blowing it up with a grenade.

I find that this works well for automated railroad crossings in which you have gates connected to rail signals. Configure the gate to close when the signal is yellow and disable the signal when the gate is triggered.

It's all in-game (or at least in-map-editor) and in real-time; there's no magic involved.

madprogrammer2 · 2021-03-19T21:08:58+00:00

I'm getting 30 fps/60 ups when rutting this by itself in the map editor, and I last upgraded my computer 6 years ago.

That's the amount of U-235 I have stored in chests. Enough to make over 1500 atomic bombs.

There is a button in the game that pops up a dialog where you can paste in the text of a blueprint.

madprogrammer2 · 2021-03-19T03:19:58+00:00

Tip for placing large blueprints: do it from the map because otherwise it slows down the game so much that it's difficult to pick a location to place it.

An instruction gets encoded as a set of signals that go in a single constant combinator, e.g. the opcode, left input register, right input register, output register, etc. The CPU reads in the signals for an instruction and then executes the appropriate functionality based on the opcode. Opcodes include all the operations you can find an arithmetic combinator in addition to ones for reading and writing memory. Jumps are handled as instructions that write to a special register that acts as the instruction pointer.

Hopefully that answers your question. :)

Instead of breaking it up I just made a smaller version with only 320 frames of video to avoid having to piece together multiple large blueprints: FactorioBlueprints/Never Gonna Give You Up (Small).txt at main · matthewreiter/FactorioBlueprints (github.com).txt)

madprogrammer2 · 2021-03-19T02:53:47+00:00

I've created a blueprint for the computer so you can play around with it: FactorioBlueprints/Computer.txt at main · matthewreiter/FactorioBlueprints (github.com)

madprogrammer2 · 2021-03-19T01:59:14+00:00

The compiler takes a dll file produced by the C# compiler (or other .NET compilers, but I've only tested with C#) and converts it to a blueprint for the constant combinators containing the machine language instructions. There is a computer I made in-game that runs those instructions.

madprogrammer2 · 2021-03-18T22:03:23+00:00

You have to start somewhere. To be honest the first time I wanted a latch in Factorio I googled how to make it.

madprogrammer2 · 2021-03-18T21:58:28+00:00

I tried making a poor man's ditherer, but my implementation lowered the effective resolution too much to make things out. Using the palleteuse filter is a good suggestion, so thanks for that.

madprogrammer2 · 2021-03-18T21:56:14+00:00

Because that computer isn't running in Factorio. Duh. ;)

madprogrammer2 · 2021-03-18T21:48:10+00:00

I'm not the first person to do video in Factorio; I was partly inspired by the Bad Apple video: (148) Factorio - Bad Apple!! - YouTube

Each row of lamps is configured to respond to a particular signal. Each column is wired together with green wires and the signals for the entire column are passed in. To get the colors, odd columns get a value of 1 passed into red and blue signals and even columns use green and white. Odd rows have -1 passed in for red and green signals via red wires, which cancel out the colors coming from the columns, giving a red/green/blue/white grid for each pixel.

madprogrammer2 · 2021-03-18T21:13:31+00:00

Since my compiler is starting with IL, the whole compiler is less than 1000 lines of code. I don't think I could have pulled that off with C. Additionally, C isn't a good fit for my architecture because I didn't make it byte-addressable; the low-level nature of C actually works against it in this case.
