Need help making a ship pitch based on a formula.

[punchyfist]

Is it possible to make a ship change its pitch based on a formula? For example, say I wanted to make the ship's pitch to change by -1 degree for every 10 m/s of velocity it had, how would I go about doing that? I have no modding experience, or even coding that much for that matter, but where would be a good point to start in trying to do something like this?

First, it is possible to change pitch on a formula like this. However, it is also rather complex to do so.

The biggest hurdle is going to be how to move the vessel. You don't have a "pitch down by X degrees command", what you have is a "pitch down by X% of available control force".

Beyond that, I'm going to point you to MechJeb, specifically the module that allows to you "hold prograde" and see how it does it for ideas. (Don't have a link for you, sorry.)

I didn't look at the MechJeb code, but IIRC from a thread on the forum, it implements a PID controller (or some other structure).

Unless you know what they are and how to use one, I suggest you take mechjeb's code and start from there.

However, I've also seen other applications that send their commands to mechjeb and let it do the hard work for them: maybe it would be better to follow their example?
