#Make a PID controlled Autopilot

Hello team!

I don't know how the current autopilot works but id imagine it would be a pain to change too far down the line. So please make sure the base code is laid out for change. I urge you to consider making it PID controlled for easy and accurate handling. Please look up PID if you are not already using such a system.

Fundamentally the Autopilot should follow not only the points set, but also the line between them. It should correct course and take into account drift, tide, wind and any such variable. Even control the cruise speed that is set. Here is a manual for a typical autopilot for boats. If you could mimic that it would be perfect in my opinion. https://www.teamsanika.dk/wp-content/uploads/2015/11/st5000-.pdf

Thank you for reading and for all the hard work you are putting into this game.

Best,

I have used that exact raymarine auto pilot unit and installed it only used the steering function nothing else. We didn't use the wind adjustment ,tide ,current. The cruise control only works with fly by wire throttle systems. Keep it simple for the devs. If the auto pilot was mated with a plotter then the plotter would keep the auto pilot on track.

#

If the auto pilot goes on heading and the plotter provides the heading presto allows the possibility to have multiple routes, record routes, reverse them and so on

This PID Autopilot IS simple. No 3d screen or plotter, no weather radar or sonar. This is a barebones when it comes to navigation between islands. We need the precision to not hit obstacles. Not the tide and stuff, but its ability to correct itself and not crash into all the island as it currently does. And please let us set waypoints wherever we want. Let us learn something and stop handholding us when it comes to placing waypoints.

#

It might not be what people want. But it is what they need.

A compass heading is simple for implementation. If every 10-20secs the auto pilot takes a new heading from the plotter/map based on the track simple. The current system works best when you use just one waypoint hardly any deviation test it.

there is no deviation because there is no wind or current. Im hopeful that they get those implimented as soon as possible though. The current autopilot is not following the navpoints or navlines, if that is a feature or a bug i cannot say.

There is wind you can clearly see it when docking

Wind is not something you see, it is something you feel. And i dont feel any wind

Every skipper takes windage in to account when Docking

I think we are talking past eachother here.

I am talking about in the game.

In the game there is no wind, other than visual rain and such. In the game i dont feel the wind, i only see it. in the game i dont feel my boat drifting in the wind or with the current. IRL all those things happen all the time, as i am trying to explain.

Sorry for the confusion. We dont need to agree on how advanced the autopilot in the game needs to be, but we can atleast agree that wind is a direct and real phenomenon of nature.
