Try using LOAD SOUND and see if it will load your MP3. JPEGs should load just the same as any other file format.
I've given you source code for a camera rotating around a fixed point. It's fully commented but post again if there's anything you don't understand.
Are you asking what sliding collision
is or do you want to know how to implement it?
**note** I just checked my source and I noticed I used camera_y# even though it's updating the z position. Don't let that throw you, it's just my bad.
