HUDCA gauge in P3Dv4

[MarkHurst 173]

A while back (!) I posted about using Dietmar Loleit's HUDCA HUD gauge in the Twin Otter. Unfortunately, when I switched to P3Dv4 recently I found that it wouldn't work. It seems the reason is that there is a small compiled gauge (Config.gau) to load the settings from the ini file, which doesn't work. The good news is that the HUD itself is an XML gauge and does work! All you have to do is stuff the mandatory Lvars with values instead of defining them in the ini file and it will work as normal! You can do this in a short Lua script. Here it is in LINDA, which is how I've done it:

ipc.writeLvar("L:Decision_High", 300)
ipc.writeLvar("L:TO_V1", 63)
ipc.writeLvar("L:TO_Rotate", 63)
ipc.writeLvar("L:TO_V2", 73)
ipc.writeLvar("L:V_Landing", 74)
ipc.writeLvar("L:Disp_Radio_High", 2500)
ipc.writeLvar("L:Flaps_Takeoff_set", 2)
ipc.writeLvar("L:aircraft_type", 1)

You can read the original discussion here.

Thanks for sharing your research.

P.S. Apparently HUDCA uses a third-party gauge by Doug Dawson and there is a 64-bit version, available here!
