스크립트는 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

public class Joypad : MonoBehaviour, IPointerDownHandler, IPointerUpHandler, IDragHandler { [SerializeField] private RectTransform rectBack; [SerializeField] private RectTransform recFront; private float radius; public void OnDrag(PointerEventData eventData) { Vector2 value = eventData.position - (Vector2)rectBack.position; value = Vector2.ClampMagnitude(value, radius); recFront.localPosition = value; } public void OnPointerDown(PointerEventData eventData) { //throw new System.NotImplementedException(); } public void OnPointerUp(PointerEventData eventData) { recFront.localPosition = Vector3.zero; } // Start is called before the first frame update void Start() { radius = rectBack.rect.width * 0.5F; } // Update is called once per frame void Update() { }

Vector3에대해선.
