Rigidbody+collider goes through colliders when transform rotates

Basically, my character with a box collider, is inside a rotating room (clock-wise for example), each boundary has a box collider.


If the transform for the room rotates too quickly, the character goes through goes through the boundaries regardless of their colliders. While researching I realized I need to use a raycast for colliding, but still I had problems. Found the DontGoThroughThings script and modify to 2D physics, but I am still having the same issue. Here is my modified script

What am I doing wrong? How can I avoid 2D colliders from going through each other?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class CustomCollider : MonoBehaviour
5. {
6.     public LayerMask layerMask; //make sure we aren't in this layer
7.     public float skinWidth = 0.1f; //probably doesn't need to be changed
8.    
9.     private float minimumExtent;
10.     private float partialExtent;
11.     private float sqrMinimumExtent;
12.     private Vector2 previousPosition;
13.     private Rigidbody2D myRigidbody;
14.     public GUIText debugText;
15.  
16.  
17.     void Start () {
18.         debugText.text = "";
19.     }
20.     //initialize values
21.     void Awake()
22.     {
23.         myRigidbody = rigidbody2D;
24.         previousPosition = myRigidbody.position;
25.         minimumExtent = Mathf.Min(Mathf.Min(collider2D.bounds.extents.x, collider2D.bounds.extents.y));
26.         partialExtent = minimumExtent * (1.0f - skinWidth);
27.         sqrMinimumExtent = minimumExtent * minimumExtent;
28.     }
29.    
30.     void LateUpdate()
31.     {
32.         //have we moved more than our minimum extent?
33.         Vector2 movementThisStep = myRigidbody.position - previousPosition;
34.         float movementSqrMagnitude = movementThisStep.sqrMagnitude;
35.        
36.         if (movementSqrMagnitude > sqrMinimumExtent)
37.         {
38.             float movementMagnitude = Mathf.Sqrt(movementSqrMagnitude);
39.             RaycastHit2D hit = Physics2D.Raycast(previousPosition, movementThisStep, movementMagnitude, layerMask.value);
40.            
41.             //check for obstructions we might have missed
42.             if (hit.collider != null)
43.                 myRigidbody.position = hit.point - (movementThisStep/movementMagnitude)*partialExtent;
44.         }
45.        
46.         previousPosition = myRigidbody.position;
47.         debugText.text = "Position: " + myRigidbody.position;
48.     }
49. }
50.  

 

Is the room rotating with Rigidbody2D.MoveRotation or Rigidbody2D.angularVelocity? If you're setting the rotation any other way (for example, modifying the transform), you're asking for trouble; the movement will not be physics compliant. Also, have you tried setting the collisionDetectionMode to continuous?

 

The room is indeed rotating modifying the transform. Let me try to use Rigidbody methods to move the room. Thanks for the reply!

 

Well I used Rigidbody2D.MoveRotation to do the rotation, also the collisiondetectionmode is continous. After certain speed the character goes through one of the walls/floors

Same with angular velocity
