Unity3D 画线插件 Vectrosity 画一个一直循环的正弦函数曲线

直接贴代码

 public Material myMaterisl;
    float fx;//曲线最左边的X坐标
    float fy;//曲线趋于直线时y轴坐标
    float fyMax = 0f;//曲线最高点
    float fyContunt = 1f;//曲线于y轴坐标的交点
    VectorLine energyLine;
    Vector2[] energyLinePoints;
    float timer;
    float energyLevel = 4f;
    void Start()
    {
        fx = 0f;
        fy = 125f;

        energyLinePoints = new Vector2[100];
        energyLine = new VectorLine("Energy", energyLinePoints, myMaterisl, 5f, LineType.Continuous);
        fnSetEnergyLinePointsMove();
    }
    void fnSetEnergyLinePoints()
    {
        for (int i = 0; i < energyLinePoints.Length; i++)
        {
            float x = Mathf.Lerp(70f, 470f, (0.0f + i) / energyLinePoints.Length);//设置点X的坐标
            energyLinePoints[i].y = fy * (1f + Mathf.Sin(x) * 0.1f * energyLevel);
            energyLinePoints[i] = new Vector2(x, energyLinePoints[i].y);//第一次设置点x,y的坐标

        }
    }
    void fnSetEnergyLinePointsMove()
    {
        for (int i = 0; i < energyLinePoints.Length; i++)
        {
            float x = Mathf.Lerp(70f, 470f, (i + .0f) / energyLinePoints.Length);//设置点X的坐标
            energyLinePoints[i] = new Vector2(x, fy);//第一次设置点x,y的坐标
        }
    }


    void Update()
    {

    }


    void FixedUpdate()
    {
        //让曲线向左运动

        int i;
        for (i = 0; i < energyLinePoints.Length - 1; i++)
        {
            energyLinePoints[i].y = energyLinePoints[i + 1].y;//让当前点的y值=它右面点的y值，就是曲线向左移动
        }
        timer += Time.deltaTime * Mathf.Lerp(10.0f, 20.0f, energyLevel);
        energyLinePoints[i].y = fy * (1f + Mathf.Sin(timer) * .1f * energyLevel);
      

    }
    void LateUpdate()
    {
        energyLine.Draw();
    }

把脚本添加到摄像机上
运行效果如图：
