유니티 new input system 뉴 인풋 시스템 이동,애니메이션 구현

유니티 new input system 뉴 인풋 시스템 이동,애니메이션 구현

 

walk 걷기 , run 달리기 , 애니메이션 구현

 

- 아래 코드는 가만히 있는 상태에서(방향키를 안누르고, 움직이지 않을때) 왼쪽 쉬프트를 눌러도 run 애니메이션이 동작하지 않음. 그러나 1. 왼쪽 쉬프트를 먼저 누르고 이동하기위해 2. 방향키를 입력하면 Run 애니메이션이 동작하지 않음.

 

이동감지코드 때문에 isRunning이 false로 되기 때문.

해결방법

 - Run 애니메이션 bool값을 이동이 있을때에만 true로 조절한다. 

 - Awake에서 Run에 if문은 빼도 된다.

private void AnimatorControllers()
    {
        float xVelocty = Vector3.Dot(movementDirection.normalized, transform.right);
        float zVelocty = Vector3.Dot(movementDirection.normalized, transform.forward);

        animator.SetFloat("xVelocity", xVelocty, 0.1f, Time.deltaTime);
        animator.SetFloat("zVelocity", zVelocty, 0.1f, Time.deltaTime);

        bool playRunAnimation = isRunning && movementDirection.magnitude > 0;
        animator.SetBool("isRunning", playRunAnimation);
    }
