Question

public void generateObjectOnTerrain()
    {
        objectPool = new ObjectPool(objectToInstantiate, objectsToInstantiate);

        float randX = 0f;
        float randZ = 0f;

        for (int i = 0; i < objectsToInstantiate; i++)
        {
            if (random == true)
            {
                //Generate random x,z,y position on the terrain
                randX = UnityEngine.Random.Range(xTerrainPos, xTerrainPos + terrainWidth);
                randZ = UnityEngine.Random.Range(zTerrainPos, zTerrainPos + terrainLength);
            }
            else
            {

            }

            float yVal = Terrain.activeTerrain.SampleHeight(new Vector3(randX, 0, randZ));

            var randScaleX = Random.Range(RandScaleMin.x, RandScaleMax.x);
            var randScaleY = Random.Range(RandScaleMin.y, RandScaleMax.y);
            var randScaleZ = Random.Range(RandScaleMin.z, RandScaleMax.z);
            var randVector3 = new Vector3(randScaleX, randScaleY, randScaleZ);

            //Apply Offset if needed
            yVal = yVal + yOffset;

            clonedObject = objectPool.GetInstance();

            if (randomScale == true)
                clonedObject.transform.localScale = randVector3;//new Vector3(randScaleX, randScaleY, randScaleZ);

            if (parent)
                clonedObject.transform.parent = this.transform;

            clonedObject.tag = "ClonedObject";

            clonedObject.transform.position = new Vector3(randX, yVal, randZ);
        }

        createdObjects = GameObject.FindGameObjectsWithTag(objname);

        UpdateList(false, "ClonedObject");
    }

这将在地形区域的随机位置实例化对象。

我希望在else中将对象放置在具有两个主要参数/变量的组中是不随机的，一个用于设置对象之间的空间，第二个用于设置如何在行中创建它们，例如，如果在objectsToInstantiate那里是20个对象，我将变量设置为4，另一个变量设置为10，然后对象将是4行，即5行，对象之间的空间将是每边10个。

如果我有55个对象并且我设置为4行，那么将有14行4，最后一行将有3个对象。

例如，连续4个对象的绘画和10个空格中的5行

如果有23个对象，那么它将会是这样的：

没有尝试，但这应该有效。

int columns = 4;
int space = 10;//set these variables from your parameters

Vector2 CalcPosition(int index) // call this func for all your objects
{
    float posX = (index%columns)*space;
    float posY = (index/columns)*space;
    return new Vector2(posX, posY);
}

我如何实例化组中的对象？
