public Vector3 localPosition ;


親の Transform オブジェクトから見た相対的な位置

Transform に親がいない場合は、値は Transform.position と同じになります。

Note that the parent transform's world rotation and scale are applied to the local position when calculating the world position. This means that while 1 unit in Transform.position is always 1 unit, 1 unit in Transform.localPosition will get scaled by the scale of all ancestors.

public class ExampleClass : MonoBehaviour { void Example() { transform.localPosition = new Vector3(0, 0, 0); print(transform.localPosition.y); } }
