explosion 스프라이트 애니메이션 만들기:

1. 스프라이트 png파일을 받아서 slice하여 sprite로 만든다.

2. gameobject를 하나 생성하여 Sprite Renderer 컴포넌트를 추가한 후에 Sprite에 생성한 explosion sprite를 드래그한다.

3. window창 -> animation으로 들어가 2번에서 만든 gameobject 선택후 클립 생성, sprite를 드래그하여 프레임을 씌운다. 

4. 원하는 프레임을 골라 이벤트를 추가한다.

5. 스크립트를 추가해 2번에서 만든 gameobject에 추가한 후 메서드를 생성, 4번에서 만든 프레임을 선택해 실행될 메서드(스크립트에있는)를 선택한다.

6.다시 프리팹화 하여 추후에 사용한다.

그냥 A 와 B사이의 벡터를 구하고 A가 바라보는 벡터의 각을 구하기엔 B가 A의 오른쪽에 있든 왼쪽에 있든 같은 angle값이 나오기때문에 구분이 불가능했다.

따라서 A의 right 벡터와 A,B사이 벡터의 내적을 구하고 이것이 0보다 큰지 작은지를 비교해 이를 해결했다.
