private RaycastHit hit;
public GameObject paintcube;
float maxdistance = 0.51f;
bool moves;

	private void FixedUpdate()
    {
		Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * 3, Color.green);
		if (Physics.Raycast(transform.position,transform.TransformDirection(Vector3.forward), out hit, maxdistance/*,layerMask*/))
        {
		    if (hit.collider.gameObject.tag == "myobstacle")
            {
                moves = false;

			}
		}
	}	
	public void movepaint()
    {
        if (moves)
        {

		}
    }
