How is RL-1 supposed to work?

[Garick]

So I've been having a blast with this game, and while I feel like a few of these levels teach a very bad lesson to potential future coders out there (a topic for another day) I've found things work pretty well.

However, I just hit RL-1. RL-0 was already pretty obtuse, but reading the instructions carefully I understood that I needed to control the vehicle and got it done with no real issue. RL-1 explains absolutely nothing to me.


Firstly, the lidar on the vehicle is a tiny box right on top of the cars bumper, but seem to detect objects as if they are several metres in front of the car. No matter what the vehicle will have a collision before it gets proper environment data. I have to assume this is a bug and the box is meant to be much further forward/longer like it is in RL-0. Example screenshot of RL-1 here: https://steamuserimages-a.akamaihd.net/ugc/1646592361162563691/0987640070CDED29AD26C1750C0FDE0B21A7B709/

I've seen some comments on older threads about 'adjusting lidar placement' by 'clicking' but I've clicked on every part of this interface (I even tried positioning the sifter module differently in case that mattered) and the lidar layout doesn't change. Am I supposed to be able to adjust the lidar? Far as I can tell the game never even mentioned it, nor is the interface allowing me to.

Then there the machine learning that is clearly not learning anything. No matter what I set initial population size or percentage of selection to, the 3 epochs play out the same way on my screen. This still happens even when adjusting those bars up and down between epochs. Every epoch I'm told 'you hit the target speed!'. Then I hit test run and I see the same thing every time: The car just slams on the brakes and comes to a complete stop. In fact it's so consistent that despite 50 runs so far with occasionally changes to random seed, the final state are exactly the same every time. And it's doubly bizarre this is what happens because as far as I can tell avoiding accidents isn't a stated objective, the car just needs to go as fast as possible!

The mission is impossible to finish, and I have to assume it's totally bugged out. But with the mission itself being so vague about the tools and their impact, I've had to spend a long time trying variation after variation to convince myself I'm not at fault, and now it's sort of sucked all the joy out.

Can someone at least confirm that this mission is totally broken? Thankfully it doesn't seem to progression block me, but it is stopping me recommending the game to anyone else for now.

"Am I supposed to be able to adjust the lidar?" - Yes, but in next RL tasks.

"Then I hit test run and I see the same thing every time: The car just slams on the brakes and comes to a complete stop." - it is a problem with visualization of the run. We checking result as the mean of different runs, and show one of them. It is not always showing "best" in terms of visual. Sorry

"The mission is impossible to finish" - It is possible

Thanks for the feedback!

Is it possible to see the other runs? All I know is that during generation tests the mean speed meets qualification but during actual test run I get a mean of some like 20km. It's like every single instance forgets all the learning done. I'd also expect some variation in what I'm seeing over the dozens of attempts I've made but the 'random' run I'm seeing is literally identical every time. That seems unlikely?

I have gold medals for the entire rest of the game at this point but this mission is unplayable. If there is a video or walkthrough for this stage I can try to replicate the steps and figure out what I'm missing.

No, sadly it is not possible for now t check other runs. It is a problem, but we didn't find a way to show it without many overcomplicated things. Sorry.

I am sure video exists, before copying the solution, be sure that it is the latest version of the game. We rebalanced and reworked those tasks a few times.

Tbh I still don't even understand how it works but still got gold medals.

I dont think anyone truly understands how the driving game missions work. Its just a bunch of numbers which somehow work and little else.
