public static Quaternion LookRotation (Vector3 forward, Vector3 upwards= Vector3.up);


forwardVector3(0, 0, 1) と同じ意味
upwardsVector3(0, 1, 0) と同じ意味


指定された forwardupwards 方向に回転します。

Returns the computed quaternion. If used to orient a Transform, the Z axis will be aligned with forward/ and the Y axis with upwards if these vectors are orthogonal. Logs an error if the forward direction is zero.
