6 years ago It's important to remember that it takes a lot more than one unit of the primary resource to make each unit of the secondary resource. For example, it takes 2500 slabs to make one concrete. So if you start with 100k slabs and 0 concrete and set it to 50%:
- The autoCraft() function notices that you have less than 50% as much concrete as you do slab, so it converts 50% of your current slabs, leaving you with 50k slabs and just 20 units of concrete
- Next tick, it checks again, and finds you still don't have enough concrete for your slabs, so it converts another 50%, leaving you with 25k slabs and 30 units of concrete
- This pattern repeats 4 more times, leaving you with 1562.5 slabs and 39.375 units of concrete. Note that your concrete supply is still far less than your slab supply, but the autoCraft() function refuses to craft less than one unit at a time.
If you wanted to get back up to 100k slabs, you'd need 50k units of concrete, which would cost a total of 125 million slabs.
Also, no, for secondary resources that cost multiple primary resources, it does not consider all of them. Production of concrete depends only on how many slabs you have, and production of alloy depends only on how much steel you have. In theory, this could mean you use up all your steel making concrete or all your titanium making alloy, but in practice, you need so much more slab than steel for concrete and so much more steel than titanium for alloy that it works fine.
The way I think secondary crafting should work is that it'll keep the secondary at the percentage I input of the primary. So if I have 100k beam and I say 1%, it'll make 1k scaffold. For something like concrete, which has two ingredients, I'd expect it to respect the one I have less of. Whenever I try to use this, though, it just makes as many of the secondary as possible, and I'm left with none of the primary. This could be a very useful feature, but it doesn't appear to work.
