Orientation, like placement, should be defined outside the xml for a given control. Otherwise, it is impossible to reuse a control unless you plan on doing it in the same orientation. It should be possible for the aircraft's model file to define a one-time transformation where you define the location of the


Can you explain, or give an example? It could be that I am not understanding
your use of the term orientation.

Ok, so I have this nice generic fuel pump toggle switch that I made for my x-100, which has a panel tilted at 15 deg. I want to also use it in my x-200, which has a panel with a vertical orientation. If I just plug it in, one of them will have a switch that is off by 15 deg. Now, I can reuse the .ac model, but I need to rotate it somehow, so I have to create a second .xml file for the x-200 that has a -15 deg rotation animation in it. Problem with this is a) I have to create a new fuel-toggle.xml file, b) the x-200 is doing a rotation transformation every frame that it doesn't have to and c) I would expect to find rotation orientation in the same place as the offsets. In other words, all six degrees of freedom of movement for the model as a whole should be defined in the same place.

So being able to define a rotation for instruments in the x-200-model.xml file instead of the fuel-toggle.xml file would be good. Being smart enough to recognize that it only needs to be done once is also good, though not nearly as important.

Another exception that might also be nice to have a way of passing

parameters to

included instruments so the instrument can do a one-time transformation on one of it's parts to adjust it's stall speed line, for instance, to the aircraft it is being installed in. I don't know how to implement this though.

That probably is not currently practical.  So we'll have to have seperate
models.  If you wanted to get fancy (which I don't recommend for this) you
could do a texture rotation based on some arbitrary value set in the aircraft

Yeah, not to hard to just make a new texture for the face of the dial for each aircraft you want to use it in. Not to much work and you only have to touch one file.
