Time.deltaTime

static var deltaTime : float

Description

The time in seconds it took to complete the last frame (Read Only).

Use this function to make your game frame rate independent.

If you add or subtract to a value every frame chances are you should multiply with Time.deltaTime. When you multiply with Time.deltaTime you essentially express: I want to move this object 10 meters per second instead of 10 meters per frame.

When called from inside MonoBehaviour's FixedUpdate, returns the fixed framerate delta time.

function Update () {
// Move the object 10 meters per second!
var translation = Time.deltaTime * 10;
transform.Translate (0, 0, translation);
}
