Camera rotation problem!!

You can use eulerAngles to rotate your camera.

For example : if (Input.GetButtonDown("Jump")) {

 transform.eulerAngles.x ++;

}

or you can use

 transform.Rotate(Vector3(1,0,0));

To make the camera rotate forward and rotate back to the original position you will need to use boolean!

For instance :

var pressing : boolean = false;

if (Input.GetButtonDown ("Jump")) {

 pressing = true;
 //make the camera rotate to the direction you want

}

if (Input.GetButtonUp ("Jump")) {

 pressing = false;
 //Make the camera rotate back to its original rotation

}

These are just the basic script to get you understand about what you need to do.

Hope this help! Cheer! ^^
