Auto Credit Based on Hannah1212's Gyroless quadcopter backup

A gyroless quadcopter with a flashlight. It can also follow stuff around, even when you’re not controlling it. It works like a real quadcopter, steering by independently changing rotor speeds, uses a hover program I made.


Manual Control:

Turn on AG 1 and 4. Use translation controls or keyboard. Can control pitch, roll, and heading. Throttle controls speed/height. Top speed is ~20 m/s. Blue side is the front.
Note: It might be unstable if you have a low frame rate.

Follow Mode:
  1. Target something
  2. Get in the air. Turn of AG 4 and start AG 5. It will follow the target. Turn on the light if you want it. Use the input hover height AG to change the height (I think default is 50m)
  3. You can take control of the target and it will continue to follow you
    Note: target system gets confused if you target something that has the same name as another craft.

    The trick is that the drone doesn’t actually continue to target something when you’re not controlling it (bc that doesn’t work). What it does is save the ID of the craft you want it to target in a variable. Then it uses craft ($targetCraftID) position instead of target position. You can then get a vector pointing at your “target” with TargetPosition-Position. Then you can lock heading on that. @HoverAerospace

    @Hannah1212 How Is It Keep Targeting The Astronaut Even After I Take Control Of The Astronaut?. I Tried To Read Your Program But I Couldn't Understand. I'm Trying To Do The Same Thing With An Astronaut And A Car, All I Want To Do Is Keep Lock Heading On Target After I Take Control Of The Target. Could You Help Me Out?

    Not really sure what you mean, a program to follow a target for any craft? I don’t really think that’s possible due to different crafts have very different steering/control methods. Although this code could be pretty easily adapted for other drones or hovery things with or without a gyroscope. @FrostyFrag

    Thx for trying it! I’ve never had an issue with min/max, but I’ve had a similar problem with vector stuff in funk. I think it’s a mobile problem but honestly idk. @Gozinya

    Love the concept! For some reason I’m getting a logged error on the FuNK max() and min() functions and the program ceases running. Did you ever have this issue?
