issues about read data and gdi+

Hi guys, when I try put my p3d gau code to fs2020, I find 2 issues.


1. I can't read GENERAL_ENGINE1_FUEL_VALVE, GENERAL_ENGINE2_FUEL_VALVE, TURB_ENGINE_1_TANK_SELECTOR, TURB_ENGINE_2_TANK_SELECTOR via lookup_var(), The "var_value.n" always 0. The data from simconnect is right, I can get the right value.


2. If I use GDI+ GraphicsPath.AddArc() , and then call SetClip(), it will fail. I try DrawPath() before SetClip() and I can get the right path. If I remove AddArc(), SetClip() works well. So I think there are something wrong in the SetClip().

Hello.

1. I've tried to read those variables editing the GdiplusAircraft sample and had no issues getting the correct values in var_value.n, matching those retrieved via SimConnect and changing on events so I'm not sure what's going wrong in your case...

2. Are you sure you're not already having an active clip when calling AddArc ?
Can you try to call ResetClip before AddArc just to make sure ?

If you provide me with your package sources, I'll be able to tell you what's going wrong.

Regards,
Sylvain
