Autopilot Coordinates System ACS

Description
Easy to use autopilot coordinates system. Connect it up as the nodes says.

Requires: A keyboard, a compass, a gps and a toggle button.

Specs:
-Size: 4*2
-Inputs: 6 (5 number, 1 on/off)
..-Target X Coordinate
..-Target Y Coordinate
..-Current X Coordinate
..-Current Y Coordinate
..-Heading(Compass)
..-On/Off toggle
-Outputs: 2 (2 number)
..-Autopilot Output
..-Length to target

Update:
-Added distance to target output.
-Fixed for the 0.5.2 verision.

Math Based on Tajin's Original Full Autopilot Example.

Thank you! that super helpful. I'll have to go look up the modulo function!

I didn't write that last function on my own, but I know everything it does. Let's say you're creation is pointing towards 10 degrees, and you want to go heading 350 degrees. Instead of turning all the way around, to get to 350, it will just turn 20 degrees the other way. Hard to explain how it achieves this, but it uses the modulo (%) function a lot, which is super helpful in these cases and that you should learn if you haven't already.

I'm trying to build my own, and I'm trying to figure out exactly what that last function does.
I realize the first function is calculating rise over run and using atan2 to avoid having to calculate the quadrants (though I could be wrong).
I'm just beginning to learn these things.

could you do a fx node that takes the pre-proccesed perfect heading readings?
"'fx' ( x +1) * 360 % 360"

DestructiveDiamonds, Well, it could, but planes are much more advanced, you can try.

Can it work on planes?

aguirre27, Yes it works very well for my helicopter. It might be very sensitve so maybe divide the Autopilot output by 2,3 or 4.

it works with helicopters?
