Unable to read CRJ v1/v2/vr datarefs

[vpil0t]

Hello,

 

I'm scratching my head around a problem I haven't been able to solve for a long time. I'm trying to access some CRJ datarefs, namely the Vspeeds of the plane, as set by the pilot prior to take-off. Philipp has published this in his CRJ Datarefs listing :

// VALUES#define CRJ_SPD_V1_VAL        "CRJ/spd/v1_value"#define CRJ_SPD_V2_VAL        "CRJ/spd/v2_value"#define CRJ_SPD_VR_VAL        "CRJ/spd/vr_value"#define CRJ_SPD_VT_VAL        "CRJ/spd/vt_value"

But I'm unable to read them (or set them) in my plugin (using Gizmo). No matter what I do, treating them as float or integer, they always read 0 (or some very strange, ever-changing numbers). Other CRJ Datarefs, like "CRJ/reverser1_arm", I can read/set them without any problems.

 

Any help would be greatly appreciated.

As a guess you're creating your datarefs before the CRJ plugin has loaded.

 

Try this:

 

function OnBoot()  dr_crj_v1 = dref.getDataref( "CRJ/spd/v1_value" )end  function OnUpdate() -- or main() if( dr_crj_v1)then  value = dref.getFloat( dr_crj_v1 )end end

If that doesn't work you can replace OnBoot with OnFirstFrame...

 

or you can use: plugins.findPlugin( "signature" )

Nope, none of the solutions work. Gizmo can communicate with the CRJ plugin because I'm able to set/read some other CRJ datarefs, but the Vspeeds are always at 0. It may be a CRJ bug or some error on my side, but I really spent a lot of time trying to solve this problem.

 

If somebody could confirm that it's indeed possible de read/set the Vspeeds values that would be great.

Do the datarefs work in DataRefEditor ?

[vpil0t]

I can't see any of the CRJ datarefs in the editor. I can see datarefs for most of my plugins (sandy barbour's, xhsi...) but not for the CRJ.

Try using dref.publish("CRJ/spd/v1_value")  and see if DRE will begin to show them after you use that Gizmo API call.

[vpil0t]

dref.publish does not seem to be a valid api Call

 

error:OnBoot.lua:35: attempt to call field 'publish' (a nil value): OnBoot

Nope, still not working with the new version. Anyway I give up, I'll find a workaround, this is just one of the numerous CRJ bugs that I'll have to dodge. Thank you for your help.
