Fs20 update code not initializing in FS24

[Mathias]

The following update code is working perfectly in FS2020 but not in FS2024, when dropping the 2020 aircraft into the 2024 community folder. The L:Var isn’t initializing though it should be true when the plane is cold and dark on a parking spot. What can be the reason?

<UseTemplate Name="ASOBO_GT_Update">
				<FREQUENCY>16</FREQUENCY>
				<UPDATE_CODE>					
					(A:IS USER SIM,bool) (A:SIM ON GROUND, bool) (A:TOTAL WORLD VELOCITY, knots) 0 == (A:PROP RPM:1, rpm) 0 == and and and
									if{ 1 (&gt;L:PropPullAvail, bool) }
										els{ 0 (&gt;L:PropPullAvail, bool) }
				</UPDATE_CODE>
			</UseTemplate>
		</Component>

you mean it’s not initializing to “1” ?
What I’d do is add a bunch of debug code into the RPN and use the behaviours console to see which of those condition simvars is failing. E.g. add

(A:IS USER SIM,bool) (>L:X_IS_USER_SIM)
(A:SIM ON GROUND, bool) (>L:X_SIM_ON_GROUND)
(A:TOTAL WORLD VELOCITY, knots) 0 == (>L:X_TOTAL_WORLD_VELOCITY_ZERO)
(A:PROP RPM:1, rpm) 0 == (>L:X_PROP_RPM1_ZERO)

Thank you B21, I’ll give that a try!

As I’m sitting here developing in MSFS2024 anyway, I inspected the simvars you’re using and found:

Perhaps instead of (A:TOTAL WORLD VELOCITY, knots) 0 == you could use (A:TOTAL WORLD VELOCITY, knots) 0.1 < ?

Ahh, good catch! Will check that out later today.
EDIT: Yep, that was it, so thanks again for the pointers.
