Question by Tharzzat · May 06 at 08:12 AM · script.verticesrect

Overlap Rect is always false

I made a rect from vertices and I can get Rect.Contains to work, but not Rect.Overlaps.

I'm trying to do something like when two rects intersect.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class MakeARect : MonoBehaviour
 {
     public List<Vector3> verts = new List<Vector3>();
 
     public List<Vector3> screenverts = new List<Vector3>();
 
     private Camera MainCam;
 
     public Rect rectVerts;
 
     public GameObject OtherRect;
 
     // Start is called before the first frame update
     void Start()
     {
         MainCam = Camera.main;
     }
 
     // Update is called once per frame
     void Update()
     {
         Mesh mesh = GetComponent<MeshFilter>().sharedMesh;
         Rect rectVerts = Rect.MinMaxRect(float.MaxValue, float.MaxValue, float.MinValue, float.MinValue);
         mesh.GetVertices(verts);
 
         for (int i = 0; i < verts.Count; i++)
         {
             Vector3 b = transform.TransformPoint(verts[i]);
             Vector3 e = MainCam.WorldToScreenPoint(b);
 
             screenverts.Add(e);
 
             if (e.x < rectVerts.xMin)
             {
                 rectVerts.xMin = e.x;
             }
 
             if (e.y < rectVerts.yMin)
             {
                 rectVerts.yMin = e.y;
             }
 
             if (e.x > rectVerts.xMax)
             {
                 rectVerts.xMax = e.x;
             }
 
             if (e.y > rectVerts.yMax)
             {
                 rectVerts.yMax = e.y;
             }
 
         }
         for (int i = 0; i < screenverts.Count; i++)
         {
             if (rectVerts.Contains(OtherRect.GetComponent<MakeARect>().screenverts[i]))
             {
                 Debug.Log(true);
             }
             else
             {
                 Debug.Log(false);
             }
         }
 
         if (rectVerts.Overlaps(OtherRect.GetComponent<MakeARect>().rectVerts))
         {
             Debug.Log(true);
         }
         else
         {
             Debug.Log(false);
         }
 
         Debug.Log(rectVerts);
     }
 }

Figured it out.

The rects were at zero.

Changed it so it works now.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class MakeARect : MonoBehaviour
 {
     public List<Vector3> verts = new List<Vector3>();
 
     public List<Vector3> screenverts = new List<Vector3>();
 
     private Camera MainCam;
 
     public Rect TestRect;
 
     public GameObject OtherRect;
 
     // Start is called before the first frame update
     void Start()
     {
         MainCam = Camera.main;
     }
 
     // Update is called once per frame
     void Update()
     {
         Mesh mesh = GetComponent<MeshFilter>().sharedMesh;
 
         Rect rectVerts = Rect.MinMaxRect(float.MaxValue, float.MaxValue, float.MinValue, float.MinValue);
 
         mesh.GetVertices(verts);
 
         for (int i = 0; i < verts.Count; i++)
         {
             Vector3 b = transform.TransformPoint(verts[i]);
             Vector3 e = MainCam.WorldToScreenPoint(b);
 
             if (e.x < rectVerts.xMin)
             {
                 rectVerts.xMin = e.x;
             }
 
             if (e.y < rectVerts.yMin)
             {
                 rectVerts.yMin = e.y;
             }
 
             if (e.x > rectVerts.xMax)
             {
                 rectVerts.xMax = e.x;
             }
 
             if (e.y > rectVerts.yMax)
             {
                 rectVerts.yMax = e.y;
             }
 
         }
 
         TestRect = rectVerts;
 
         Rect rect = OtherRect.GetComponent<MakeARect>().TestRect;
 
         if (rectVerts.Overlaps(rect))
         {
             Debug.Log(true);
         }
         else
         {
             Debug.Log(false);
         }
 
         Debug.Log(rectVerts);
     }
 }
