First read
Snypir's exelent Intro to Camera Scripting tutorial. Read it again and again untill you understand it completely... then read it some more
.
Then move on to
Camera.sqs tutorial by
Messiah.
Camera.sqs is a very handy litle tool that is built in the game, with it you can script cutscenes in matter of minutes (if your in a hurry ;D), and also get coordinates for unit placement.
If those still don't help you, you could try search the editors depot for more camera tutorials.
And finally, I've made a litle example mission (only the intro) for you...
Ãt may not be exactly what your looking for but it should help you get on your way with camera scripting.
It contains a small intro with a example "music" file defined in a description.ext...
The Intro is editor driven so you can easily edit it. Just place it in your
users\username\ folder
Download it
here[EDIT]Oh and theres also a
tutorial mission by
macguba that I think you should check out... :-X
