unity 随机获取圆内点

    System.Random random = new System.Random(1000);
//半径随机 ，弧度随机
 public Vector2 GetCirclePoint(int m_Radius)
    {
    //随机获取弧度
        float radin = (float)GetRandomValue(0, 2 * Mathf.PI);
        float x = m_Radius * Mathf.Cos(radin);
        float y = m_Radius * Mathf.Sin(radin);
        Vector2 endPoint = new Vector2(x, y);
        return endPoint;
    }
    public double GetRandomValue(double min,double max)
    {
        double v = random.NextDouble() * (max - min) + min;
        return v;
    }
