[我有一个近120,000星的数据集和215个星的测试数据集（取自主要数据集），并且我正在编写一个程序来读取数据集并在3D地球模型周围绘制恒星图。
void listStars()
{
int i = 0;
while (i < (StarDataBank.Instance.NumOfStars))
{
int primaryID = int.Parse(StarDataBank.Instance.StarIDID[i]);
string properName = StarDataBank.Instance.StarName[i];
string HIPID = StarDataBank.Instance.StarIDHIP[i];
string HDID = StarDataBank.Instance.StarIDHD[i];
string HRID = StarDataBank.Instance.StarIDHR[i];
string GLID = StarDataBank.Instance.StarIDGL[i];
string BFID = StarDataBank.Instance.StarIDBF[i];
decimal rightAscension = Convert.ToDecimal(StarDataBank.Instance.StarRA[i]);
decimal declination = Convert.ToDecimal(StarDataBank.Instance.StarDec[i]);
decimal Mag;
decimal CI;
float scale = 0;
int r = 0;
int g = 0;
int b = 0;
Decimal.TryParse((StarDataBank.Instance.StarMag[i]), out Mag);
Decimal.TryParse((StarDataBank.Instance.StarCI[i]), out CI);
if (PlayerPrefs.GetInt("dynamicSize") == 1)
{
if (Mag < -1)
{
scale = 77.5f;
}
else
{
if (Mag > -1 && Mag <= 5)
{
scale = 52.5f;
}

{
if (Mag > 5 && Mag <= 10)
{
scale = 32.5f;
}
else
{
if (Mag > 10 && Mag <= 15)
{
scale = 17.5f;
}
else
{
if (Mag > 15 && Mag <= 20)
{
scale = 7.5f;
}
else
{
if (Mag > 20 && Mag <= 25)
{
scale = 2.5f;
}
}
}
}
}
}
}
else
{
scale = 20;
}
StartCoroutine(placeStars(primaryID, properName, HIPID, HDID, HRID, GLID, BFID, rightAscension, declination, Mag, CI, scale));
i++;
}
DestroyImmediate(StarDataBank.Instance.gameObject);
}
IEnumerator placeStars(int primaryID, string properName, string HIPID, string HDID, string HRID, string GLID, string BFID, decimal rightAscension, decimal declination, decimal magnitude, decimal colourIndex, float scale)
{
var thisStar = (GameObject)Instantiate(prefabStar, transform.position + getVectors(Convert.ToDecimal(rightAscension), Convert.ToDecimal(declination)), Quaternion.identity);
thisStar.name = (primaryID).ToString();
thisStar.transform.parent = StarObject.transform;
thisStar.transform.localScale = new Vector3(scale, scale, scale);
thisStar.AddComponent<Star>().newStar(primaryID, properName, HIPID, HDID, HRID, GLID, BFID, rightAscension, declination, magnitude, colourIndex);
yield return null;
}
使用只有215星的较小测试数据集，我可以将Star类附加到每个实例化星。
但是对于拥有约12万颗星的大型完整数据集，Unity编辑器仅在按下播放按钮后挂起。当我注释掉以下行时：thisStar.AddComponent<Star>().newStar(...);程序按预期工作，场景中绘制了每颗星星，唯一的事情是Star类未附加到每个新实例化的星星上。
这意味着AddComponent函数不能很好地与我的代码配合使用，尤其是在使用大型数据集的情况下。
是否有更有效的方法将Star类附加到每个实例化的Star GameObject？
而且，当我用完单例后销毁单例时，它会有所不同吗？我使用IEnumerator实例化是否有所不同？
编辑：这是星级班：
public class Star : MonoBehaviour { Simulation simulationInstance; public int primaryID; // primary key NEEDS TO BE SET public string properName; // some stars have names NEEDS TO BE SET public string HIPID; // ID of star from Hipparcos catalogue NEEDS TO BE SET public string HDID; // ID of star from Henry Draper catalogue NEEDS TO BE SET public string HRID; // ID of star from Harvard Revised catalogue NEEDS TO BE SET public string GLID; // ID of star from Gliese catalogue NEEDS TO BE SET public string BFID; // ID of star from BayerFlamsteed catalogue NEEDS TO BE SET public decimal rightAscension; // right ascension of star NEEDS TO BE SET public decimal declination; // declination of star NEEDS TO BE SET public decimal magnitude; // magnitude of the star NEEDS TO BE SET public decimal colourIndex; // colour index of the star NEEDS TO BE SET public int scale; // size of the sphere that will represent the star AUTOMATICALLY SET public int red; // red colour (0-255) AUTOMATICALLY SET public int green; // green colour (0-255) AUTOMATICALLY SET public int blue; // blue colour (0-255) AUTOMATICALLY SET public double x; // AUTOMATICALLY SET public double y; // AUTOMATICALLY SET public double z; // AUTOMATICALLY SET void Start() { simulationInstance = FindObjectOfType<Simulation>(); } public void newStar(int primaryID, string properName, string HIPID, string HDID, string HRID, string GLID, string BFID, decimal rightAscension, decimal declination, decimal magnitude, decimal colourIndex) { this.primaryID = primaryID; this.properName = properName; this.HIPID = HIPID; this.HDID = HDID; this.HRID = HRID; this.GLID = GLID; this.BFID = BFID; this.rightAscension = rightAscension; this.declination = declination; this.magnitude = magnitude; this.colourIndex = colourIndex; } public void tellStarInfoPanel() { simulationInstance.starInfoPanelManager(primaryID, properName, HIPID, HDID, HRID, GLID, BFID, rightAscension, declination, magnitude, colourIndex); } }编辑：我已将listStars（）用作协程，而将placeStars（）用作常规方法
public void placeStars(int primaryID, string properName, string HIPID, string HDID, string HRID, string GLID, string BFID, decimal rightAscension, decimal declination, decimal magnitude, decimal colourIndex, float scale)
{
var thisStar = (GameObject)Instantiate(prefabStar, transform.position + getVectors(Convert.ToDecimal(rightAscension), Convert.ToDecimal(declination)), Quaternion.identity);
thisStar.name = (primaryID).ToString();
thisStar.transform.parent = StarObject.transform;
thisStar.transform.localScale = new Vector3(scale, scale, scale);
thisStar.GetComponent<Star>().newStar(primaryID, properName, HIPID, HDID, HRID, GLID, BFID, rightAscension, declination, magnitude, colourIndex);
starsRendered++;
}

避免在AddComponent中使用performance critical code
如果您认为AddComponent（）在计算上过于繁琐，那么最好仔细看一下Start组件，或者甚至更好地运行应该准确查明罪魁祸首的Unity探查器工具，将是明智的。
您需要知道，这不是Monobehaviour / Component OOP模型的好用例。为此，您可能需要考虑切换到preview
