Я делаю 2D RPG для своего дипломного проекта, и я нахожусь в точке, где я хочу генерировать свои подземелья случайным образом.
Я следую этому уроку http://www.rombdn.com/blog/2018/01/12/random-dungeon-bsp-unity/, чтобы сделать случайносгенерированное подземелье.
После множества исследований я обнаружил, что алгоритм BSP генерирует дизайн подземелья, который я желаю для своей игры.Я следовал инструкциям, приведенным в ссылке, шаг за шагом.Я предоставил свой сценарий, чтобы вы могли его увидеть:
public class BoardManager : MonoBehaviour {
public GameObject floorTile;
public GameObject corridorTile;
public int boardRows, boardColumns;
public int minRoomSize, maxRoomSize;
private GameObject[,] boardPositionsFloor;

public SubDungeon left, right;
public Rect rect;
public Rect room = new Rect(-1,-1, 0, 0); // i.e null
public int debugId;
private static int debugCounter = 0;
public List<Rect> corridors = new List<Rect>();
public SubDungeon(Rect mrect) {
rect = mrect;
debugId = debugCounter;
debugCounter++;
}
public bool IAmLeaf() {
return left == null && right == null;
}
public bool Split(int minRoomSize, int maxRoomSize) {
if (!IAmLeaf()) {
return false;
}
// choose a vertical or horizontal split depending on the proportions
// i.e. if too wide split vertically, or too long horizontally,
// or if nearly square choose vertical or horizontal at random
bool splitH;
if (rect.width / rect.height >= 1.25) {
splitH = false;
} else if (rect.height / rect.width >= 1.25) {
splitH = true;
} else {
splitH = Random.Range (0.0f, 1.0f) > 0.5;
}
if (Mathf.Min(rect.height, rect.width) / 2 < minRoomSize) {
Debug.Log ("Sub-dungeon " + debugId + " will be a leaf");
return false;
}

// split so that the resulting sub-dungeons widths are not too small
// (since we are splitting horizontally)

Помещения создаются идеально, и сообщений об ошибках нет.Я заметил, что CreateCorridorBetween не вызывается ниоткуда, даже в блоге автора;следовательно, коридоры не создаются.Как я могу назвать это в моем коде?
