How to modify the gravity between scenes?

Questions & Answers
1

I modified the gravity from edit/project settings/physics/gravity.But now after I build the scenes, all of them have the same gravity.How can I have have different gravity values on different scenes?

Put a script into every scene, and have that script change the gravity inside Awake(). It would go something like this:

var gravity = Vector3 (0, -9.81, 0);

function Awake () {
     Physics.gravity = gravity;
}
