【问题描述】:
所以我得到了这段代码,它用地砖填充了特定大小的给定区域。
while (roomsPlaced < roomCount.maximum)
{
Vector3 randomPosition = RandomPosition();
int roomHeight = GetRandomNumber(8, 15);
int roomWidth = GetRandomNumber(6, 15);
if (OutOfMap(randomPosition, roomHeight,roomWidth))
{
continue;
}
if (roomsPlaced > 0) {
if (Overlaps(new Rect(randomPosition.x, randomPosition.y, roomWidth, roomHeight), roomPositions[roomPositions.Count -1]))
continue;
}
roomPositions.Add(new Rect(randomPosition.x, randomPosition.y, roomWidth, roomHeight));
for (int x = (int)randomPosition.x; x <= (int)randomPosition.x + roomWidth; x++)
{
for (int y = (int)randomPosition.y; y <= (int)randomPosition.y + roomHeight; y++)
{
if (x == randomPosition.x || y == randomPosition.y)
toInstantiate = floorTiles[Random.Range(0, floorTiles.Length)];
GameObject instance = Instantiate(toInstantiate, new Vector3(x, y, 0f), Quaternion.identity) as GameObject;
instance.transform.SetParent(boardHolder);
}
}
roomsPlaced++;
}
这里的函数应该检查当前矩形是否与列表中的最后一个矩形重叠。
bool Overlaps(Rect rA, Rect rB)
{
return (rA.x < rB.x + rB.width && rA.x + rA.width > rB.x && rA.y < rB.y + rB.height && rA.y + rA.height > rB.y);
}
但是当我的一些房间重叠时,我仍然有问题。 我做错了什么,我应该怎么做才能解决这个问题?
