Cloth.externalAcceleration

Description

A constant, external acceleration applied to the cloth.

Use this to simulate constant forces on the cloth, such as wind waving a flag. See Also: Cloth.randomAcceleration.

    // Make this cloth fall at half speed (if is affected by gravity).

    transform.GetComponent.<Cloth>().externalAcceleration =  -Physics.gravity/2;

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void Example() {
        transform.GetComponent<Cloth>().externalAcceleration = -Physics.gravity / 2;
    }
}
