我在我的场景中有一台相机，我用第三方设备控制 . 如果我旋转设备，向前倾斜等等，我的相机会复制相同的动作 . 然而，我不知道如何始终确保我的相机面向前方并向前移动，尽管Y旋转 .
例如，我的相机从点0,0,0开始，旋转值相同 . 如果我将相机旋转90度（任一侧）并向前移动相机，我的视图现在会向侧面移动 . 我怎样才能得到它以便我的相机面对哪里，那是我向前的方向？
到目前为止，这是我的代码：
private void MoveForward()
{
Debug.Log("yaw: " + yaw + " pitch: " + pitch + " roll: " + roll);
if( pitch > maxPitch.x && pitch < maxPitch.y && reversePitch == false)
{
camera.rigidbody.AddForce(0, 0,-pitch);
// camera.transform.position += new Vector3(0,0, -pitch);
}
else if ( pitch > maxPitch.x && pitch < maxPitch.y && reversePitch == true)
{
camera.rigidbody.AddForce(0, 0, pitch);
// camera.transform.position += new Vector3(0,0, pitch);
}
else
{
camera.rigidbody.velocity = Vector3.zero;
// camera.transform.position = new Vector3(0,0,0);
}
}
private void MoveSideways()
{
if( roll > maxRoll.x && roll < maxRoll.y && reverseRoll == false)
{
camera.rigidbody.AddForce( roll, 0, 0);
}
else if ( roll < maxRoll.x && roll > maxRollNegative && reverseRoll == false)
{
camera.rigidbody.AddForce( roll, 0 ,0);
}
else if( roll > maxRoll.x && roll < maxRoll.y && reverseRoll == true)
{
camera.rigidbody.AddForce( -roll, 0, 0);
}
else if ( roll < maxRoll.x && roll > maxRollNegative && reverseRoll == true)
{
camera.rigidbody.AddForce( -roll, 0 ,0);
}
else
{
camera.rigidbody.velocity = Vector3.zero;
}
}
private void RotateAround()
{
if(reverseYaw == true)
{
target = Quaternion.Euler(0, yaw,0);
}
else
{
target = Quaternion.Euler(0, -yaw,0);
}
transform.rotation = Quaternion.Slerp(camera.transform.rotation, target, Time.time *rotationSpeed);
}

发生这种情况是因为
Rigidbody.AddForce采用世界空间矢量，但是您给它一个局部空间矢量 . 使用Transform.TransformDirection将矢量从本地空间转换为世界空间 .
