[Unity3d] UGUI 조이스틱 인터페이스

By  at 2월 13, 2021  , , ,  No comments

 UGUI로 간단하게 만들수 있다. 

6.(scene 전환내용에 이어서)외곽의 원, 그밑으로 핸들을 UI -> Image로 만들고 색상과 Source Image(Knob)으로 만들어둔다.

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.
