적 패턴 디자인 구상하고 코딩테스트 시험이랑 곂쳐서 요 몇일간 개발을 좀 못했다 데헷~(맞다 변명이다.)

적 패턴은 각각 공격마다 쿨타임을 적용시킬거다.
그 다음에 무기가 있을때, 그리고 없을때 enum으로 나눠서 패턴을 세분화 하고,
만약 무기가 있을때는 중,장거리 그리고 근거리 2개로 나눠서 세분화 하고,
무기가 없을때는 중거리, 근거리 2개로 나눠서 만들 것이다. (아마 하다가 애니메이션이 없으면 근거리 하나로만 작업할 것이다.)

무기파트이다 무기를 없을때, 있을때 구분해야 하기 때문에 Active를 따로 만들어서 사용했고, Attach할때 애니메이션을 맞춰준다.

일단 필요한것들만 만들었다.
