I’m trying to write a simple addon to export Blender files as C structs to be easily used by opengl as described by Apple as their preferred method for use on the iPhone/iPad. I’m new to python and blender scripting, and thought it would be relatively simple to follow along some existing scripts and just modify their output for my own uses. However, even before I’m delving into the real meat and potatoes part of it, I’m having problems getting my script to enable in blender. Specifically, I’m having problems with menu_func, which even though I copied over pretty much verbatim from similar scripts, seems to screw things up and blender won’t let me enable my barebones script with it included. I’m sort of lost as to what the problem is, like I said I’m new to python and blender scripting, and as far as I can tell there’s no way within blender to get any debugging information when attempting to enable a script. Also like I said, 95% of this is just copied over from a working script, all I’ve done so far is change the class names and I’m already running into problems. So first, can anyone tell me what my specific problem with this code is (look at the comments at the very bottom for what is causing the problem), and second, for the future, what’s the best way to debug these scripts?
