检查项目是否重叠

我有几个房间是随机放置的，所以我必须检查房间是否重叠。房间的大小为 10x10，出于测试原因，房间完全并排放置（它们在场景中不重叠）。地板是一种变换，由 1 个或多个变换组成（在本例中，由一个正方形组成，但对于其他形式，它可能是 2 个或更多）。

为了检查它们是否重叠，我有这个不起作用的功能。调试日志始终介于 3 和 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，对于正在阅读的人 (2/2016)OverlapBox是Unity最新版本刚刚添加的全新调用。

Edit：按照 Joe 的建议，我使 OverlapBox“可见”，但它们似乎处于正确的位置和正确的尺寸（红色是我的房间，灰色是碰撞器）......

我现在已经可以使用了。每个 OverlapBox 都放置正确，但它们仍然发生碰撞，因为它们距离对象“太近”。此更改修复了它：

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)
