Collider2D[] results = new Collider2D[10]; int numColliders = Physics2D.OverlapBoxNonAlloc(new Vector2(0, 0), new Vector2(2, 2), Quaternion.identity, LayerMask.GetMask("Obstacle"), results); for (int i = 0; i < numColliders; i++) { Collider2D collider = results[i]; // Do something with the collider, e.g. apply damage, open a door, etc. }This code creates a 2D box area with a center at (0,0) and half-size of (2,2), and then checks for any colliders on the "Obstacle" layer that overlap with this box. We use a results array of length 10 to store any colliders found, and then iterate through the results to perform some logic on each collider. This method is part of the UnityEngine.Physics2D namespace, which is part of the Unity game engine SDK.
