Question by yun1029 · Aug 11, 2019 at 07:19 PM · drag-and-drop

How to drop on the specific area?

I made prefabs to generate randomly and drag and dropping them. But the problem is that I can't drop them in a specific area. I have 36 different areas where I want to drop them. Where should I put the slot script and will I have to change the drag and drop script? I'll post both scripts below. Thank you.

Drag and Drop Script

 private bool dragging;

 public void Update()
 {
     if (dragging)
     {
         transform.position = new Vector2(Input.mousePosition.x, Input.mousePosition.y);
     }
 }

 public override void OnPointerDown(PointerEventData eventData)
 {
     dragging = true;
 }

 public override void OnPointerUp(PointerEventData eventData)
 {
     dragging = false;
 }


Slot Script

 public Color okColor;
 public Color noColor;
 public bool placeable;
 public GameObject mCamera;
 public bool placed;


 // Use this for initialization
 void Start()
 {
     mCamera = GameObject.Find("Main Camera");
 }

 // Update is called once per frame
 void Update()
 {
     RaycastHit hit;
     Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
     float camDistance;

     if (placed == false)
     {
         if (Physics.Raycast(ray, out hit))
         {
             Debug.Log(hit.transform.name);
             camDistance = hit.distance;
             Vector3 m = Input.mousePosition;
             m = new Vector3(m.x, m.y, camDistance);
             Vector3 p = mCamera.GetComponent<Camera>().ScreenToWorldPoint(m);

             transform.position = new Vector3(p.x, p.y, 0.6f);

             if (Input.GetMouseButtonUp(0) && placeable == true)
             {
                 placed = true;
                 GetComponent<Renderer>().material.color = Color.white;
                 transform.position = new Vector3(p.x, p.y, 0.6f);
                 Destroy(this);
             }

             if (Input.GetMouseButtonUp(1))
             {
                 Destroy(this.gameObject);
             }

         }
     }

     RaycastHit hit2;

     if (Physics.Raycast(transform.position, new Vector3(0, 0, -1), out hit2, 10.0F))
     {
         if (hit2.transform.tag == "Map")
         {
             placeable = true;
             GetComponent<Renderer>().material.color = okColor;
         }
         else
         {
             placeable = false;
             GetComponent<Renderer>().material.color = noColor;
         }

     }

 }
