Roundrobin stops

Post by fik0z »

So, I started my first marathon playthrough, and chose to make cityblocks really early (as soon as I got them at green science if im frank), and there I met factorio limits - trains when going to stations with same name - go to closest one, so when I dont have enough input/trains it leads to them (or it if its solo train) just going around between two stations. and it really hurt my situation when I dont have enoguh anything but build the grid, some ten trains, some smoll smelters, and even my production/needs of most resources are like really smoll (that smol mall!) and then it hit me - I wanna logic it. first was frustration and mod installation - cybersyn works PERFECTLY, but feels a bit unfair and unintential by desing - trains shouldnt be drones, so there I hurt my brain, created some other variants (like simply adding numbers one by one to enable stations) and then I made this thingy -

Train stops that turn one by one when trains are send to them and only when they need to turn on

For this one its for one material only (I'm not going to create ltn in this system, it will be too much for me, and completely unnecessary) - using global timer and 2 variables going through radar (Green) - its counter itself (named material signal), and a signal to pause this counter (pause signal). when counter equals station number (made x3 cos somehow it takes 2 ticks to pause it, I think thats cos I'm just a noob) and if there's not enough material counter will stop when it reaches this stations number, wait for train to be send there, and if it does it again resumes its run till it touches some other stations number.
Station number should be different for every station, possible number from 1 to any (less than max timer parameter divided by 3) so even 60 such stations will rotate at 3 seconds if you have enough train input
for inserters and when to enable station I made 2*request/6 - per every chest resources.

after setting those 2 variables and placing first main station, two combinators on top shouldn't be copied - they are global timer for this one station type
if you want to create another station type you should use 2 different symbols(signals) than first station.
so now even one short train works for 5 stations that eat everything you throw at them!



Edit: some stations become trainwreck of wires lol, if I want to have close to multi resource low volume stations)
