		euler.z = Mathf.Lerp(euler.z, -acc.x * maxTurnLean, 0.2f);

}

这是通过手机转动控制飞船传动的代码, 主要问题在FixedUpdate 部分,euler.xyz应该如何于input.accleration 的方向对应.

euler.y = acc.x * turnSpeed;

euler.z = Mathf.Lerp(euler.z, -acc.x * maxTurnLean, 0.2f);

euler.x = Mathf.Lerp(euler.x, acc.y * maxTurnLean, 0.2f);    这些 不太 明白
