[2.0.47] Asteroid collector sporadically not collecting chunks

Post by Seppl1 »

This might be related to this older thread: viewtopic.php?t=118441
Sometimes, asteroid collectors don't collect asteroid chunks that are very much inside their collection ranges.

I have attached two saves where this problem can be seen after a few seconds. Space platform "Nauvis-Vulcanus-Hauler" has 3 asteroid collectors pointing upwards, spaced such that their areas overlap a bit. I created the space platform by copying everything from the "Traumschiff Surprise" space platform in one go, including the hub. Maybe that has something to do with it.
None of the collectors have any filters, inventory restrictions or circuit conditions applied.

In Example 1, look at the rightmost collector. There are two chunks coming in:

The metallic chunk (1) is eventually collected by the center collector, but the oxide chunk is not collected at all. But: If I set a filter for metallic chunks on the rightmost collector, it does collect that metallic chunk. But no matter what filter I set, it never collects the oxide chunk.

In Example 2, look at the leftmost collector. It does collect a metallic chunk at the start, and then an oxide chunk immediately after the platform starts moving. Then a carbonic chunk after a long delay, and then it misses another carbonic chunk.

Thanks for the report. I think this is a duplicate of 124493. When platform speed is not stable (and especially if the platform just left the orbit), asteroid collectors may not get all asteroid chunks because their projected path and expected time to get in range change. You can enable show-selected-asteroid-collector-tracking debug option and mouse over a collector to see this behavior.

Hmmm. If I understand right, this issue should not happen when a space platform never moves, or after a long time after it stopped moving (once all asteroids that existed before that are definitely gone), right?

I became aware of this because I was surprised by how long it took for the space platform to buffer up ammo and thruster fuel and oxidizer. I don't know for sure now whether I noticed this issue before I tried to speed up the platform for the first time, but just in case, I'll keep an eye on this next time round. (I might also just be way off on my estimation of how long it takes to pick up enough asteroid chunks for my platform.)

Correct. As long as the speed doesn't change, the prediction algorithm for asteroid collectors is accurate.
