Autopilot in Unreal Engine

[MikeKilo]

I have a project running with the JSBSimMovement component, with a model of Cessna 172 X and all is working as it should.
I want to use the c172ap inside the unreal engine, so I can direct it to waypoints and control it as a UAV.
Is there any way to do it with the current plugin, or should a different plugin be made in order to access the autopilot capabilities?

If you use blueprints you can use these blueprint nodes to send any command to JSBSim.
https://github.com/JSBSim-Team/jsbsim/tree/9f92a0603498ff09dd84e77b6e6022b866fcb50f/UnrealEngine#extended-commands-and-properties

You can look through these scripts to find the various autopilot commands which you can use in the blueprint nodes. https://github.com/JSBSim-Team/jsbsim/tree/master/scripts

So for example this script which uses the c172x:

jsbsim/scripts/c172_cruise_8K.xml

Lines 80 to 87 in ae4652a

	<event name="Hold heading and altitude">
	<condition>simulation/sim-time-sec ge 5</condition>
	<set name="ap/heading_setpoint" value="200"/>
	<set name="ap/heading_hold" value="1"/>
	<set name="ap/altitude_setpoint" value="4000.0"/>
	<set name="ap/altitude_hold" value="1"/>
	<notify/>
	</event>

You can see the commands which you can enter in the blueprint node as:
Property: ap/heading_setpoint Value: 200
Property: ap/heading_hold Value: 1
Property: ap/altitude_setpoint Value: 4000
Property: ap/altitude_hold Value: 1

A value of 1 and 0 will enable/disable the appropriate systems.
There are other commands if you search and some examples from other aircraft might be useful as well.

And a caution that using incorrect property names or properties that haven't been loaded yet by jsbsim will crash UE5. So if UE5 crashes when using commands, then this is why.

Thank you very much, everything works like you said!
