public static float Clamp01 (float value);

描述

将值限制在 0 与 1 之间并返回值。

如果值为负,则返回 0。如果值大于 1,则返回 1。

// Set the position of the transform to be that of the time
// but never less than 0 or more than 1
function Update () {
    transform.position = Vector3(Mathf.Clamp01(Time.time), 0, 0);
}

// Print a random number every second. This number is chosen over a // range from startValue to endValue. The random number is clamped // to between zero and one by Clamp01().
