Mandelbrot Set 函数崩溃

Question

我为 Mandelbrot Set 函数做了一个 sim，zn + 1 = power(zn) + c 它可以工作，但是当我达到功能不稳定的地步时，它会崩溃，现在我有一个布尔值，当 true 时，它​​会连接所有圆圈，当它为 false 时，它​​很好（不崩溃），但当它打开时，它会崩溃，代码的工作原理如下：

开始： 建立一个圆列表，并通过方程确定 pos，然后在圆和最后一个圆之间拉一条线， 更新： 然后，当您移动圆圈时，它会使用已经创建的 gameobj 列表来更新那里的位置。

你可以在这里尝试一下： 构建 github： git

但它崩溃了:(，这是代码：

 private void updateCircles()
{
    StartUpdateCircles();
}


private void StartCircles()
{
    float x = BlackCircle.anchoredPosition.x;
    float y = BlackCircle.anchoredPosition.y;
    AllCircles.Add(BlackCircle.gameObject);

    for (int i = 1; i < itarations; i++)
    {
        Vector2 RedCircleVec2 = RedCircle.anchoredPosition;
        Vector2 LastCircleVec2 = AllCircles[i - 1].GetComponent<RectTransform>().anchoredPosition;
        GameObject Circle = Instantiate(BlackCircle.gameObject, Vector3.zero, Quaternion.identity);

        Circle.transform.SetParent(CanvasPerent);
        AllCircles.Add(Circle);

        x = Mathf.Pow(x, 2);
        x -= Mathf.Pow(LastCircleVec2.y, 2);
        x += RedCircleVec2.x;

        y = (2 * LastCircleVec2.x
            * LastCircleVec2.y) + RedCircleVec2.y;

        Circle.GetComponent<RectTransform>().anchoredPosition = new Vector2(x, y);

        if (HasWire)
        {
             GameObject wire = GenrateWireStart(LastCircleVec2
           , Circle.GetComponent<RectTransform>().anchoredPosition);

            AllWires.Add(wire);
        }

    }

}

private void StartUpdateCircles()
{
    float x = BlackCircle.anchoredPosition.x;
    float y = BlackCircle.anchoredPosition.y;
    for (int i = 1; i < itarations; i++)
    {
        Vector2 RedCircleVec2 = RedCircle.anchoredPosition;
        Vector2 LastCircleVec2 = AllCircles[i - 1].GetComponent<RectTransform>().anchoredPosition;
        RectTransform ICircle = AllCircles[i].GetComponent<RectTransform>();


        x = Mathf.Pow(x, 2);
        x -= Mathf.Pow(LastCircleVec2.y, 2);
        x += RedCircleVec2.x;

        y = (2 * LastCircleVec2.x
            * LastCircleVec2.y) + RedCircleVec2.y;

        ICircle.anchoredPosition = new Vector2(x, y);
        if (HasWire)
        {
            
              GenrateWireUpdate(LastCircleVec2
                ,ICircle.anchoredPosition, i);
            
            
        }
    }
}

public GameObject GenrateWireStart(Vector2 NodeA, Vector2 NodeB)
{
    GameObject Connector = new GameObject("connector", typeof(Image));
    Connector.transform.SetParent(CanvasPerent);
    RectTransform ConnectorRT = Connector.GetComponent<RectTransform>();

    ConnectorRT.anchorMin = new Vector2(0, 0);
    ConnectorRT.anchorMax = new Vector2(0, 0);

    Connector.GetComponent<Image>().color = new Color(0f, 0f, 0f, 0.25f);

    Vector2 dir = (NodeB - NodeA).normalized;
    float distance = Vector2.Distance(NodeA, NodeB);

    ConnectorRT.sizeDelta = new Vector2(distance, 0.005f);

    ConnectorRT.position = NodeA + dir * distance * .5f;

    ConnectorRT.localEulerAngles = new Vector3(0, 0, UtilsClass.GetAngleFromVectorFloat(dir));

    return Connector;
}

public void GenrateWireUpdate(Vector2 NodeA, Vector2 NodeB, int i)
{
    RectTransform ConnectorRT = AllWires[i - 1].GetComponent<RectTransform>();
    Vector2 dir = (NodeB - NodeA).normalized;
    float distance = Vector2.Distance(NodeA, NodeB);
    ConnectorRT.sizeDelta = new Vector2(distance, 0.005f);
    ConnectorRT.position = NodeA + dir * distance * .5f;
    ConnectorRT.localEulerAngles = new Vector3(0, 0, UtilsClass.GetAngleFromVectorFloat(dir));
}

请帮助，谢谢.

我简单地查看了你的代码，你似乎从你的计算中得到了一些无效的位置，比如无限/未定义的位置，或者只是一些对于 Unity 来说太远的位置。

我可以通过简单地将位置限制为例如

 x = Mathf.Clamp(Mathf.Pow(x, 2), -Screen.width, Screen.width);
 x = Mathf.Clamp(x - Mathf.Pow(LastCircleVec2.y, 2), -Screen.width, Screen.width);
 x = Mathf.Clamp(x + RedCircleVec2.x, -Screen.width, Screen.width);

 y = Mathf.Clamp((2 * LastCircleVec2.x * LastCircleVec2.y) + RedCircleVec2.y, -Screen.width, Screen.width);

将所有位置限制为某些屏幕外最大位置来删除这些
