public float decelerationRate ;

Description

The rate at which movement slows down.

The deceleration rate is the speed reduction per second. A value of 0.5 halves the speed each second. The default is 0.135. The deceleration rate is only used when inertia is enabled.

public class ExampleClass : MonoBehaviour { public ScrollRect myScrollRect;

public void Start() { // assigns a new value to the decelerationRate of the scroll rect. // The higher the number the longer it takes to decelerate. myScrollRect.decelerationRate = 5.0f; } }
