Question

我有几个房间是随机放置的，所以我必须检查一个房间是否重叠。房间大小为10x10，出于测试原因并排放置（它们在场景中不重叠）。地板是一个变换，由一个或多个变换组成（在这种情况下，一个正方形，但对于其他形式，它可能是2个或更多）。

要检查它们是否重叠，我有这个功能不起作用。调试日志总是在3到61之间。

public bool Overlapping()
{
    //Lists for the position and of the size of each floor transform
    List<Vector3> positions = new List<Vector3>();
    List<Vector3> sizes = new List<Vector3>();
    //Check if floor consists out of more than 1 transform
    if (Floor.childCount > 0)
        foreach (Transform t in Floor)
        {
            positions.Add(t.position);
            sizes.Add(t.lossyScale);
        }
    else
    {
        positions.Add(Floor.position);
        sizes.Add(Floor.lossyScale);
    }

    //Save old room pos and move it out of the way
    Vector3 position = this.transform.position;
    this.transform.position = new Vector3(0, 100, 0);

    //Check if any floor transform would overlap
    for (int i = 0; i < positions.Count; i++)
    {
        //Make overlap box visible
        GameObject rec = GameObject.CreatePrimitive(PrimitiveType.Cube);
        rec.transform.localScale = sizes[i];
        rec.transform.localPosition = positions[i];
        rec.transform.localRotation = Quaternion.Euler(0, 0, 0);

        //Returns the colliders which are overlapping
        if (Physics.OverlapBox(positions[i], sizes[i] / 2).Length > 0)
        {
            Debug.Log(Physics.OverlapBox(positions[i], sizes[i] / 2).Length);
            //return this room to it's old position
            this.transform.position = position;
            return true;
        }
    }

    //return this room to it's old position
    this.transform.position = position;
    return false;
}

顺便说一句，任何人阅读（2/2016）OverlapBox都是一个全新的号召，Unity刚刚加入了最新版本。

编辑：正如Joe所建议的那样，OverlapBox'可见'，但它们似乎位于正确的位置并且尺寸正确（红色是我的房间，灰色是碰撞器）。 ...

我现在就开始工作了。每个OverlapBox都被正确放置，但它们仍然在相撞的地方，因为它们太靠近了＃39;对象。这个改变修正了它：

if (Physics.OverlapBox(positions[i], new Vector3(sizes[i].x - 0.01f, sizes[i].y - 0.01f, sizes[i].z - 0.01f) / 2, rotations[i]).Length > 0)
