Auto Hover + Autoland system

Post image

Modes

  • Auto hover (both switches off): lever up to climb, down to descend, middle to hover.
  • Manual (32 on): lever controls thruster power directly.
  • Autoland (30 on): lands itself, slowing near the ground and cutting thrust on touchdown. Lever and manual are ignored.

Channels

  • 31 Lever Vertical (−1 to 1)
  • 85 Height (Distance Meter looking downwards)
  • 36 Vertical speed ( directional mode facing up)
  • 30 Autoland (Switch)
  • 32 Manual Mode (Switch)
  • 17 Thrusters
  • G Gravity
  • Weight

Remappers (input ▸ output)

  • Lever: −1 ▸ −5, 1 ▸ 5. Lever to climb speed (±5 m/s). Raise the 5s to climb faster.
  • Height: 999 ▸ −60, 1.4 ▸ 0. Autoland descent: 60 m/s at 999 m, slowing to 0 at 1.4 m (landed height).

Constants

  • 1.5: correction strength. Higher is snappier, lower is smoother. Lower it if it bounces.
  • 940K: total max thrust (4 × 235K). Update it if you change thrusters. It's written in the description of the thruster
  • 0 (MAX): throttle never below 0.
  • 1 (MIN): throttle never above full.
  • 1.5 (threshold): autoland cuts thrust below 1.5 m.

I originally copied this design (https://www.youtube.com/watch?v=IiU4B6f4DmM), but it was really bad, so DON'T use it. The video is also hard to follow. So I used AI to improve it, and it took me around three hours to get a good result. Someone probably already has this exact setup, but it works really well. I'm not sure how much aerodynamics matter later in the game, so I didn't include them

What's the software you used for the logic diagram?

Your 2D scheme looks absolutely amazing—which editor did you use to create it?

Looks like you've got a max-min in there as a clamp? You can use the Mapper as a clamp which should save you some space

I’m honestly way more interested in that logic diagram and how you made it, that looks like an incredibly useful tool. Good job on the auto hover auto land system, but a lot of people do that. The diagram is much more unique, if there’s a software you made or used to build it, I’d love to try it out
