Blacksquare Grand Duke starter has defeated me

[Flapsfullsend]

Just getting my legs under me with pilotsdeck / fsuipc. With devmode and hubhop I was able to figure out some basics.

Things fell apart trying to setup my streamdeck+ for the Grand Duke starter however.

I don't really know what I'm looking at here but if anyone could help point me in the right direction I'd really appreciate it. The magneto rotary has 4 positions with (0 off, 4 start) and I am able to set the positions without issue. The problem is that the sim (MSFS 2024) seems to only actually run the starter with a mouse click+drag+hold using the code below. Ultimately I'd like to put that into a pilotsdeck composite action but not sure where to even start. 

(M:Event) 'WheelUp' scmi 0 == if{ 
    (L:BKSQ_IgnitionPosition_1, number) 4 < if{ (L:BKSQ_IgnitionPosition_1, number) 1 + (>L:BKSQ_IgnitionPosition_1, number) } 
    (E:SIMULATION TIME, seconds) (>L:starterKnobReturnTime_L, number) 
} 
els{ 
    (M:Event) 'WheelDown' scmi 0 == if{ 
        (L:BKSQ_IgnitionPosition_1, number) 0 > if{ (L:BKSQ_IgnitionPosition_1, number) 1 - (>L:BKSQ_IgnitionPosition_1, number) } 
    } 
    els{ 
        (M:Event) 'Lock' scmi 0 == if{ 
            (M:RelativeX) (>O:_LastX) 
        } 
        els{ 
            (M:Event) 'Unlock' scmi 0 == if{ 
                0 (>O:_LastX) 
            } 
            els{ 
                (M:Event) 'LeftDrag' scmi 0 == if{ 
                    (M:RelativeX) (O:_LastX) - sp0 
                    0.008 0.07 0.05 3 (M:InputType) case (>O:_InputThreshold) 
                    l0 abs (O:_InputThreshold) > if{ 
                        l0 (O:_InputThreshold) / abs flr sp1 
                        l0 (O:_InputThreshold) % abs sp2 
                        :1 (* for loop *) 
                        l1 0 <= if{ g2 } 
                        l1 -- sp1 
                        l0 0 > if{ 
                            (L:BKSQ_IgnitionPosition_1, number) 4 < if{ (L:BKSQ_IgnitionPosition_1, number) 1 + (>L:BKSQ_IgnitionPosition_1, number) } 
                            (E:SIMULATION TIME, seconds) (>L:starterKnobReturnTime_L, number) 
                        } 
                        els{ 
                            (L:BKSQ_IgnitionPosition_1, number) 0 > if{ (L:BKSQ_IgnitionPosition_1, number) 1 - (>L:BKSQ_IgnitionPosition_1, number) } 
                        } 
                        g1 
                        :2 
                        l0 0 > if{ 
                            (M:RelativeX) l2 - (>O:_LastX) 
                        } 
                        els{ 
                            (M:RelativeX) l2 + (>O:_LastX) 
                        } 
                    } 
                } 
            } 
        } 
    } 
} 
quit

Presumably you use the lvar BKSQ_IgnitionPosition_1 to move the position of the switch, no? Does this have any actual affect on the starter, besides moving the magneto rotary?

I am not that familiar with such complex gauge calc code, but it looks like you also need to set the starterKnobReturnTime_L lvar when you do this. You can set both lvars using a calculator code preset. The rest of the code is setting O-type (component) variables which I am not familiar with. 

Are any other (standard) events or input events logged (in FSUIPC log / console) when you move the starter in the VC?

If its just a matter of holding the magneto rotary in one position for a certain amount of time before changing the position back, you could do this by writing a macro or lua script. But its probably more complicated than that.

You could try asking the community if its possible to create a preset to replicate that code. The best place for this type of question would be on the MF Discord server, in the MSFS2024 channel.

Sorry but I don't have this aircraft so cannot really look into this in more detail.
