感谢您的帮助，并指出了我可以改进这一点的更好方法。
答案在于您导入的名称空间，但不使用：-）System。收藏。通用。使用列表或适合应用程序需要的内容。
理解序列中出现的模式，例如，对于每3个值后创建立方体，X值变为5，Y值递增1。对于每3个值，我们可以使用像_cubeOffset这样的变量
因此，由于您必须创建9个多维数据集，因此从XValue=4.0f和YValue=-0.5f开始。现在，通过将i从0取到8，开始创建9个多维数据集的循环。第一步是检查i%3==0，如果是，则设置XValue=4.0f和YValue=0.5f
_cubeOffset = 3;
_startXCube = 4.0f;
_startYCube = -0.5f;
_cubes = new List < GameObject > ( TOTAL_CUBES );
for ( int i = 0; i < TOTAL_CUBES; ++i ) {
/*
* This below check will run when i = 0, 3, 6
* at this point we set the _startXCube to 4.0f and
* increment the previous value of _startYCube by 1.
* Therefore at i = 0
* _startXCube = 4.0f
* _startYCube = 0.5f, since the previous value of _startYCube is -0.5f
*
* i = 3
* _startXCube = 4.0f
* _startYCube = 1.5f, since the previous value of _startYCube is 0.5f
*
* i = 6
* _startXCube = 4.0f
* _startYCube = 2.5f, since the previous value of _startYCube is 1.5f
*/
if ( i % _cubeOffset == 0 ) {
_startXCube = 4.0f;
_startYCube += 1.0f;
}
_startXCube += 1.0f; // Incrementing _startXCube since we need 5.0f, 6.0f and 7.0f values
GameObject gb = GameObject.CreatePrimitive ( PrimitiveType.Cube );
gb.transform.position = new Vector3 ( _startXCube, _startYCube, 0.0f );
_cubes.Add ( gb );
Debug.Log ( $"<color=lightblue>Creating Cube -> X:{_startXCube} Y:{_startYCube} Z:0</color>" );
}
同样，我们可以为气缸创建如下逻辑：
_startZCylinder = -10.0f;
_cylinders = new List < List < GameObject > > ( TOTAL_COLUMNS );
for ( int i = 0; i < TOTAL_COLUMNS; ++i ) {
_cylinders.Add ( new List < GameObject > ( TOTAL_CYLINDERS ) );
_startYCylinder = -1.0f;
_startZCylinder += 5.0f;
for ( int j = 0; j < TOTAL_CYLINDERS; ++j ) {
_startYCylinder += 2.0f;
GameObject gb = GameObject.CreatePrimitive ( PrimitiveType.Cylinder );
gb.transform.position = new Vector3 ( 0.0f, _startYCylinder, _startZCylinder );
_cylinders [ _cylinders.Count - 1 ].Add ( gb );
Debug.Log ( $"<color=lightblue>Creating Cylinder -> X:{0.0f} Y:{_startYCylinder} Z:{_startZCylinder}</color>" );
}
}
请注意，对于这些代码片段，我使用了如下列表数据结构：
private List < GameObject > _cubes;
private List < List < GameObject > > _cylinders;
这是整个剧本
using System.Collections.Generic;
using UnityEngine;
public class CreatePrimitive : MonoBehaviour {

}

}

}
您可以创建一个静态函数，如下所示
public class CubeHelper
{
public static GameObject Creating(Vector3 position, PrimitiveType primitiveType)
{
GameObject createdGameObject = GameObject.CreatePrimitive(primitiveType)
createdGameObject.transform.position = position;
return createdGameObject;
}
}
然后只是传递参数：
Gameobject sthg = CubeHelper.Creating("your vector3", "your primitive type");
