好的，接下來的程式碼如下：

// 計算角色是否正在移動
isMoving = horizontalVelocity > 0.1f || horizontalVelocity < -0.1f;

// 更新角色的動畫
animator.SetBool("isGrounded", isGrounded);
animator.SetBool("isJumping", isJumping);
animator.SetBool("isMoving", isMoving);
animator.SetFloat("verticalVelocity", verticalVelocity);
animator.SetFloat("horizontalVelocity", horizontalVelocity);

// 更新角色的滑鼠旋轉
if (Input.GetMouseButton(1))
{
    mouseRotation = Input.GetAxis("Mouse X") * mouseRotationSpeed;
    transform.Rotate(0, mouseRotation, 0);
}
}

// 計算兩個向量之間的角度
float AngleBetweenVector2(Vector2 vec1, Vector2 vec2)
{
    Vector2 diference = vec2 - vec1;
    float sign = (vec2.y < vec1.y) ? -1.0f : 1.0f;
    return Vector2.Angle(Vector2.right, diference) * sign;
}
