Raycasting not working on all sides?

Questions & Answers
1

Hi,

I’m having an issue with 2d raycasting. I have a player object(blue rectangles) that moves around a polygon(blue polygon). When I run a physics2d.raycast(green lines) from the player to the center(trasform.position) of the target polygon, it returns a hit, but ONLY on the left side of that polygon. If I move to the right, it ceases to return a hit and the hit.point position sticks to the top-most or bottom-most vertex of the polygon collider.

Does anyone know why such an error occurs?

Here is my raycasting:

	//raycast from rectangle to selected shape/body
		RaycastHit2D hit 
			= Physics2D.Raycast(transform.position, 
			                    polygon.transform.position,
			                    Mathf.Infinity,
			                    1 << LayerMask.NameToLayer("Ground"));

Thanks for any suggestions.

Just a tool to help you along the way with this, Debug.DrawRay(). I would also take out the infinity, since you are not limiting your raycast with it.

Debug.DrawRay(transform.position, polygon.transform.position, Color.red);

Good Luck!
