}

Taunt -> 점수 획득시 호출 -> 플레이어 웃음 소리 랜덤으로 발생 -> 같은 웃음소리면 다시 호출해서 다른 웃음소리가 나올때까지 호출함(재귀호출)

Linecast-> 라인 캐스트를 사용해서 플레이어의 밑이 Ground인지 파악한다. -> 오브젝트의 레이어 이름이 Ground여야 됨..

groundCheck -> 빈 게임 오브젝트를 캐릭터 밑에 위치 시킴. 인스펙터창에서 모양을 지정해줄수있어서 어디 위치했는지 쉽게 알수 있음.

if(h * rigidbody2D.velocity.x < maxSpeed)

rigidbody2D.AddForce(Vector2.right * h * moveForce);

if(Mathf.Abs(rigidbody2D.velocity.x) > maxSpeed)

rigidbody2D.velocity = new Vector2(Mathf.Sign(rigidbody2D.velocity.x) * maxSpeed, rigidbody2D.velocity.y);

플레이어의 속도가 최대속도보다 아래면 힘을주고 아니면 속도를 최대속도로 제한해준다.

if(h > 0 && !facingRight)

// ... flip the player.

Flip();

// Otherwise if the input is moving the player left and the player is facing right...

else if(h < 0 && facingRight)

// ... flip the player.

Flip();

플레이어의 모양을 보고 왼쪽이면 왼쪽을 바라보게 오른쪽이면 오른쪽으로 바라보게 한다.

if(jump)

{

// Set the Jump animator trigger parameter.

anim.SetTrigger("Jump");

// Play a random jump audio clip.

int i = Random.Range(0, jumpClips.Length);

AudioSource.PlayClipAtPoint(jumpClips[i], transform.position);

// Add a vertical force to the player.

rigidbody2D.AddForce(new Vector2(0f, jumpForce));

// Make sure the player can't jump again until the jump conditions from Update are satisfied.

jump = false;

}

점프 중이면. 랜덤으로 점프 사운드를 재생하고 위쪽으로 힘을 가한다(AddForce)

-> 모든 물리관련 동작은 FixedUpdate()에서 실행한다.

솔직히 아직도 재귀함수에 대한 이해가 부족한거 같음

된다는건 알고있지만 뭔가 이상하다..
