2D Raycasting For Ground/Ceiling Checks
I've researched everywhere trying to figure this out but I can't wrap my mind around it.
I want to know when the player touches the ground or has ceiling above it (when crouching). And I'd like the ray to be visible in scene view.
I thought I'd do this:
private BoxCollider2D collider;
private int mask;
private float distToGround;
void Awake ()
{
collider = GetComponent<BoxCollider2D>();
mask = ~(LayerMask.GetMask ("Platforms"));
distToGround = collider.bounds.extents.y;
}
void GroundCeilingCheck ()
{
Debug.DrawRay (transform.position, -Vector3.up, Color.red, distToGround);
if (Physics2D.Raycast (transform.position, -Vector3.up, distToGround, mask)
{
isGrounded = true;
}
else
{
isGrounded = false;
}
}
But that didn't cast a ray at all.
Any help would be greatly appreciated!
Why not just use the players OnCollision? Just check to see if the collision is at its feet.
I did until I tried to implement more functionality such as sliding. So now I need ground and ceiling checks and I feel it'd be cleaner and more efficient to raycast ins$$anonymous$$d of dealing with ground and ceiling colliders
