[2.0.76] Plasma throughput from reactor to generator has limit

Post by 2833680766 »

Although it's unlikely to occur in normal gameplay, I still decided to post it.
When I was playing an infinite-level mod in sandbox mode, I noticed that the highest-level fusion reactor and fusion generator were behaving a bit strangely. The highest-level reactor has a speed of 308 plasma/s.
Then I realized that each interface between a fusion reactor and a fusion generator has a speed limit of 300 even though the connection between reactors is unlimited.

After that, I reproduced this bug in Space Age. Below is the blueprint.

When pasting this blueprint, we can see that the generators at the back cannot receive plasma.
3:What did you expect to happen instead? It might be obvious to you, but do it anyway!
I expect plasma transfer between fusion generators to be able to transfer at infinite speed, just like steam transfer between steam turbines.

Given that those are directional pipe connections meaning there is a fluid flow happening on each plasma connection and given that fusion generators have fluid boxes with volume of 10 out of which only 5 participates in the fluid flow per tick, this works to be exactly 5/tick which equals 300/s. Possible solutions would be to add more complexity to fluid flow so it could transfer fluid across multiple hops (unlikely) or increasing fusion generator's plasma fluid box from 10 to something larger. I will leave this for raiguard to decide.

Directional connections do not have unlimited throughput; they are limited by the source and destination fullness ratios as well as the free space in the destination (and the amount in the source). A fusion generator can only transfer five per tick at max because it can only hold 10 fluid and reserves the other 50% for its own operations. In order to make it infinite, the connections would need to be changed to be bidirectional, which we are not going to do.
Don't forget, you're here forever.
