如何在另一组对象之后实例化一个对象并将其放在两者之间

Question

我试图在一组对象移动一定距离后实例化一个对象。在我的代码中，我正在制作墙壁，我想做的是创建 2 个杆，拖动鼠标并在杆之间创建一堵墙，我有这么多。我想要遵循的是，如果 2 个杆之间的距离超过了第一个墙支撑的位置并添加到索引中，并且在第一个墙和末端杆之间实例化了一个新墙。

void adjustWall()
{
    //start and end pole look at each other
    startPole.transform.LookAt(endPole.transform.position);
    endPole.transform.LookAt(startPole.transform.position);
    //gets the distance between the start and end poles
    float distance = Vector3.Distance(startPole.transform.position, endPole.transform.position);
    //places the wall between the 2 poles, rotates it to face both of them and scales it between them.
    wall.transform.position = startPole.transform.position + distance / 2 * startPole.transform.forward;
    wall.transform.rotation = endPole.transform.rotation;
    //wall.transform.localScale = new Vector3(wall.transform.localScale.x, wall.transform.localScale.y, distance); 
    if (distance > 10)
    {
        //if the distance is greater than 10, set wall, add it to an index then instaniate a new wall between that wall and the end poll. Do this Once until it's time to create a new wall.
    }
}

adjustWall 在我的更新函数中被调用。

在运行时实例化预制件 https://docs.unity3d.com/Manual/InstantiatingPrefabs.html

public GameObject prefab;

// ...

if (distance > 10)
{
    // Calculate your target position
    Vector3 pos;

    // Instantiate the wall's GO
    var wall = Instantiate(prefab, pos, Quaternion.identity) as GameObject;
}
