raycasting

I'm trying to use Physics2D.Raycast in order to check if the player is on the ground (I know that there are other approaches to check if the player is on the ground but I think that the raycast is the most reliable). The problem is that in my scenario it returns the player itself as hit and I really don't understand why and what should I do. My code (in PlayerController ) is the following: public bool IsGrounded () { Bounds bounds = this.playerCollider.bounds; Vector3 rayOrigin = bounds.center; rayOrigin.y -= bounds.extents.y; RaycastHit2D hit = Physics2D.Raycast (rayOrigin, Vector2.down, 0.1f

I am running into a bit of difficulty selecting objects with the orthographic camera using the raycaster. Though, I have no problem with it when I use a perspective camera. The only thing I am changing when switching between the two is the type camera. I am able to select faces on the orthographic view, but it is only loosely related to where I am clicking on the screen. When I can click far away from the object and it will still come back as if it has hit the object near its center. Any ideas on what I am missing here? I am basing much of my code on this example , and am hoping to achieve a

Unity's Raycast functions has a parameter you could use to raycast to a particular GameObject. You can also use that parameter to ignore particular GameObject. For exmple the Raycast function: public static bool Raycast(Vector3 origin, Vector3 direction, float maxDistance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal); The layerMask parameter is used to specified which Objects should/should not receive the raycast. 1 .How do you raycast to a particular GameObject which is in a layer called "cube"? 2
