This will get you started - its not CAMERA Collision, but sparky is working.
I did notice a glitch - but I think its because at certain angles the Eular reports 180degree opposite where you want to be - also I KNOW sometimes OBJECT's and CAMERA's don't report correct Angles intermittantly, and this can usually be squelched by rotating on a different axis than the one you just turned on.. like if turned left, look up, then down, maybe left then right.
Stupid I know - but its intermittant and might exmplain the ocassion "FLASH" where it seems like you did a 180 turn for ONE frame.
anyways...try this:
#include "SC_Collision.h"

dbPositionObject(2, 200, 50, 50);
SC_SetupObject(1, 1, 2); // Groups other than ZERO for stuff you hit
SC_SetupObject(2, 1, 2); // reserve ZERO for your player :)
// I think this is a good idea - I'm not sure you can have a group item hit something
// in the same group. That MIGHT be an issue you came across and didn't know it.
