[TIL] 유니티 raycast

Physics2D.Raycast

Debug.DrawRay

 if(PV == null) {
 	return;
}
        
if(PV != null) {
	Debug.DrawRay(new Vector2(NetworkManager.instance.player.transform.position.x, NetworkManager.instance.player.transform.position.y - 17), Vector2.down * 10f, Color.red);
 	RaycastHit2D rayHit = Physics2D.Raycast(new Vector2(NetworkManager.instance.player.transform.position.x, NetworkManager.instance.player.transform.position.y - 17), Vector2.down, 10f, LayerMask.GetMask("object"));

    if(rayHit.collider != null) {
       if(rayHit.collider.gameObject.tag == "Player")
       {
       		// Debug.Log(rayHit.collider.gameObject);
       		// Debug.Log(rayHit.collider.gameObject.GetComponent<BoxCollider2D>().bounds);
            Debug.Log(rayHit.collider.gameObject.GetComponent<SpriteRenderer>().sortingOrder);
            this.GetComponent<SpriteRenderer>().sortingOrder = rayHit.collider.gameObject.GetComponent<SpriteRenderer>().sortingOrder - 1;
       } 
     } else {
       this.GetComponent<SpriteRenderer>().sortingOrder = 0;
     }
}

Debug.DrawRay로 먼저 그리고
raycast를 선언하면 보기 쉽다
