I'm editing a freeware aircraft, an L-39 http://www.rikoooo.com/downloads/viewdownload/65/727, to have units that I'm used to like knots, etc. I'm trying to figure out where the code for the decision height knob is:

 

 

I'm looking all through the code of this specific aircraft and can't even find a reference to it. Any ideas?

You won't find it. XML scripts for 3d objects such as that knob are embedded into the compiled model (.mdl) file and cannot be edited like a 2d XML gauge script.

 

When the model is exported from the modeling program (GMax or Max), it is combined with the definitions in the modeldef.xml file and two interim files are generated:

 

1. aircraftname.x

2. aircraftname.xml

 

When the compiler is run, those two files are combined to generate the model file: aircraftname.mdl

 

Once compiled, there is no practical way to "decompile", modify, then "recompile."

Ah, I see. Thank you. I'll go see what I can do with other things.
