我正在使用 Minions Art 草系统，我希望能够从另一个脚本调用并重新生成第 301 行上的当前网格，我无法找到一种方法与另一个脚本上的任何内容进行交互，所以当我生成网格时，它会生成草

我还使用塞巴斯蒂安·拉格斯程序生成教程，使用衰减贴图

从你的问题和巨大的代码片段中很难看出。
一般来说：通过创建方法
public staticrefout我没有数行数，但我只是假设你指的是
CreateNewGrassObject所以我会将其转换为
public static GrassComputeScript CreateNewGrassObject()
{
var grassObject = new GameObject();
grassObject.name = "Grass System - Holder";
var grassCompute = grassObject.AddComponent<GrassComputeScript>();
// setup object
var grassData = new List<GrassData>();
grassCompute.SetGrassPaintedDataList = grassData;
return grassCompute;
}
所有其他本地值也可以通过例如
var newGrass = GrassPainterWindow.CreateNewGrassObject();
var gameObject = newGrass.gameObject;
var grassData = newGrass.SetGrassPaintedDataList;
由于它不包含特定于编辑器的代码，您甚至可以考虑将其移至类似的帮助器类中
public static class GrassTools
{
public static GrassComputeScript CreateNewGrassObject()
{
...
}
}
因此即使在构建中也可以使用。
