An interesting concept. Incidentally, the concept at 6:54 is De Morgan's Laws, which provide a means to transform NAND into NOR (&vv), which only requires the odd NOT to flip things. It's frequently used in logic design because the workings of a transistor mean that a digital signal typically gets inverted. Also, fun fact: On the British railway network, a signal is said to be "on" when at danger and "off" when clear.

I didn’t know about the British “on” and “off,” maybe the OpenTTD convention comes from something like that

@@LugnutsK Given its a 50/50 choice, it could just as easily be coincidence, but who knows. The system works just as well either way, the only difference being that the AND gate in red-positive is an OR gate in green-positive (&vv).

Another entirely different parallel I see is with digital electronic circuits. There it is a design principle that if a part of a circuit is not powered, that you want the outputs of this unpowered part of the circuit to read out as a boolean value that has the meaning "off" or "inactive" (which is in most cases mapped to boolean zero). In openttd circuits, trains are the thing that "power" the circuit. But in openttd, if there is no train in a block (so that the block is "unpowered"), then the signal is green. So looking at things through the electronic circuit parallel, the green openttd signal would correspond to the "off" state (boolean zero).

My advice would be don't try to understand everything in one go. I would probably start with the AND gate, then once you understand the AND gate, move to the NOT gate, once you understand the AND and NOT gates, then move on to the OR gate. My other piece of advice would be to practice building and using them. Do something like generate a very flat landscape with the tree algorithm set to none, pay off your starting loan and use the cheats (wiki.openttd.org/Cheats) to get money. I wouldn't recommend using cheats in a proper game but for learning new things in a less harsh playing environment I think its fine.

Don't sweat it too much, it's definitely the craziest of the crazy stuff you can do in OpenTTD. If you've never played with minecraft redstone or irl circuits then trying to learn logic gates at the same time as learning OpenTTD is gonna be really hard. Also the vast majority of OpenTTD players never even touch logic and still have a good time so its really about what you find fun :)

@himagainstill 5 жыл бұрын

@Frédérick Grenier - the complication is in the building. For the logic, all you need to know is how the gates work, and that given any one of AND, OR, NAND and NOR, you can construct the other three using NOT. After that, the hard part is understanding why the gates are built this way (the NOT confused the heck out of me at the first viewing). A NAND B NOT [A AND B] A NOR B [NOT A] AND [NOT B] A OR B NOT [ [NOT A] AND [NOT B] ]

I played this industry and liking it. The circuits are new to me, I would like to know how it is different from usual train tracks in operation. Also why it is design that way. This better have an important impact on the industry and gaming performance. I can just copy what is done here and not understand at all. I am not good at signal either so my chances of using this is minimal. It is good and informative to see this new ideas.

@LugnutsK 4 жыл бұрын

Generally trains are controlled by their orders. But with logic you can make trains behave in ways that orders don't allow. In this case the logic determines the train's destination. Overall, using logic won't give you a huge $ advantage or anything, but personally I think it is a lot of fun.

I tried to rebuild the layout at around 7:34 but I fail. Trains seem to ignore the exit signal at the entry and get stuck. 1 lane is always ignored, the other occupied and a second train waiting behind. I can only force my trains to go to the desired path, if I set explicit destinations. But I‘d like to self-regulate them (only have 1 vague order to pick up load). Do you have any console commands input before? What are your orders of these long trains?

On both input tracks you have extra angled tracks that make "arrows". (Like what you would use on a "reverser" track.) Are they required for some reason here? Thanks

@LugnutsK 4 жыл бұрын

Ah, yes they are. The pathfinder prefers paths that have multiple options. If it didn't have them, the pathfinder would see 1 dead end due to the two-way EOL, and the other path might also be a dead end due to a terminus station. So the train might not behave as expected. But with them it makes sure that an open path will always be preferred over the other path.

Per your example, how does the Iron Ore and Coal Industry related to? Each can produce simultaneously without affecting each production. I understand that the Port produces Eng Supplies which is needed by both Iron Ore and Coal to a certain production level, on the other hand once the Iron ore and coal receive Eng Supplies it produces different products. So why is there a need to simultaneously deliver Eng Supplies to both Iron Ore and Coal while both produces different products? Is this just a mere example to illustrate the circuits? Are both Iron Ore and Coal have another destination that needs both to have equal amounts of produce? Please just help me understand. Thank you.

@LugnutsK 4 жыл бұрын

As you put it, it is just a example to illustrate the circuits, one that I made for the video. But in a proper FIRS game you would transport the iore and coal to the next industry in the chain. And it's important since FIRS gives better production for a particular secondary industry if it receives multiple types of cargo (instead of just one).

I had this problem as well. I noticed the trains wouldn't accelerate to full speed because of the signal which would slow them down. I had to change the "Train acceleration model" from original to Realistic. Now may trains move as fast as on this video.
