Based on some of the warpout camera code, I think I may have gotten camera translations working, along with more flexible camera rotation movement.
I didn't feel like making more SEXPs, so I dropped camera support into the scripting system. This also made it easier to implement multiple-camera support, so you can have any number of cameras to play with now. (You can switch between them with setCamera).
Most of the functions are in the testing library:http://fs2source.warpcore.org/temp/scripting.html#Testing
The functions to move the camera are part of the camera handle:http://fs2source.warpcore.org/temp/scripting.html#camera
I still need to actually test this. I coded myself a script-eval SEXP, but have been having trouble getting it to work
However, all the scripting stuff should be implemented in this build, if you want to give it a shot:http://fs2source.warpcore.org/exes/latest/C02042006.zip
