U3D如何让物体旋转一定角度

艾西格亚

以相机为例，写入以下代码：



public var cm:Camera;//Camera Object

public var maxRotationAngle = 20;//Max Rotation Angle each side

private var currentAngle = .0;

function Update ()

{

    var cfAngle =  15 * Time.deltaTime;

    if(Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.LeftArrow))

    {

        cfAngle = -cfAngle;

    }

    else if(Input.GetKey(KeyCode.D) || Input.GetKey(KeyCode.RightArrow))

    {

    }

    else

    {

        return;

    }

    var newcurrentAngle = currentAngle + cfAngle;

    if(newcurrentAngle > maxRotationAngle) newcurrentAngle = maxRotationAngle;

    if(newcurrentAngle < -maxRotationAngle) newcurrentAngle = -maxRotationAngle;

    cfAngle = newcurrentAngle - currentAngle;

    currentAngle = newcurrentAngle;

    cm.transform.Rotate(cm.transform.InverseTransformDirection(Vector3.up) * cfAngle);

   

}
