Pushback Offsets Don't React To Values Being Written

[FPVSteve]

Hi,

I decided to monitor the pushback offsets and noticed the following:

0x31F0 = Current Pushback State
0x31F4 = Pushback (Set)

0 = Straight
1 = Left
2 = Right
3 = No Pushback

Edit: it looks like 0 is now 4 in MSFS, so it is no longer zero indexed.

(1 and 2 directions may be mixed up in this report but it is neither here no there as the result is the same)

If I write to the offset 0x31F4 directly, the value is stored and the value in 0x31F0 also changes to reflect the state.

However, nothing happens in the sim.

If, however, I use SHIFT+P, the offset monitor comes back with "SimRead: 31F4='PUSHBACK STATE' (also 31F0) INT32: 4(0x00000004)."

The aircraft starts to push back... however none of the directional values work, and you cannot cancel the pushback by setting "3" as the value ... you have to SHIFT+P again

Is there any way to make the simulator react to the offsets (0 (or 4) and 3 as the values) instead of needing SHIFT+P - and also to respond to a turn request by specifying either 1 or 2 as the value?

Here is a sample log (NOTE THAT I HAVE ALSO TRIED TO WRITE TO BOTH OFFSETS IN MSFS - IN OTHER SIMS, ONLY WRITING TO 31F4 IS REQUIRED - then 31F0 updates automatically)

  (Attempt to START by writing an integer of 4)
 733296 Monitor IPC:31F0 (S32) = 4
 733312 Monitor IPC:31F4 (S32) = 4

----- nothing happens ---

(SHIFT+P PRESSED)
   733359 SimRead: 31F4="PUSHBACK STATE" [also 31F0]
            INT32: 4 (0x00000004)

---- aircraft pushes back ----

(Attempt to STOP by writing an integer of 3)
   734281 Monitor IPC:31F0 (S32) = 3
   734296 Monitor IPC:31F4 (S32) = 3

---- nothing happens ----

(SHIFT+P PRESSED)
   734343 SimRead: 31F4="PUSHBACK STATE" [also 31F0]
            INT32: 3 (0x00000003)

---- aircraft stops pushing back ----

I'll update to handle the change in values - I'll post a version to test sometime tomorrow.

Pushback left/right are behaving in the opposite way of how theywere previously working - this has been reported to Asobo. For the time being, I will swap the controls sent so that previous functionality is maintained.

Could you try the attached build please:  FSUIPC7.exe

[FPVSteve]

Great news - it worked perfectly.

I tried multiple combinations:

Straight / Stop

Straight,  Left, Stop,

Straight, Right, Stop,

Straight, Right, Left, Stop,

Left, Stop

etc.

 

All fine.

Thank you very much for that.

Steve how did you do that?

I used the .exe that john attached, then in the button & switch assignement I selected:

toggle pushback & param 0 for straight  

toggle pushback & param 3 for stop

toggle pushback & param 1 for left  but doesn't turn

toggle pushback & param 2 for right but doesn't turn

in each case when toggle it start but if i toggle again it stops.

 

last question: how can i write an offset?

I look in the manual but it's not clear to me (I'm definitely not an expert by now!)

Hi,

Toggle Pushback control will only toggle Pushback ON or OFF, the value has no effect. To send Left(1), Right (2), Straight(0) or OFF(3) you need to send the value to the Offset 31F4. Instead of selecting Toggle Pushback you choose Offset Dword Set, see pic. This would need 4 buttons or you use instead for Straight and Off the Toggle Pushback control but that would then switch from Left or Right to OFF and needs another press.

Great!

thank you Thomas. I learned another thing. For sure I'll use this function and i'll test all the other offset controls.
