晚上好，圣诞快乐!
我想制作自己的 Dungeon-Generator。所以我决定首先在一些空房间中生成，并在同一步骤中放置墙壁。
public void generateRoom(byte[][] dungeon){
if(roomCornerDownLeft.x + roomWidth < dungeon[0].length && roomCornerDownLeft.y + roomHeigth < dungeon.length ){
setRoomFloor(dungeon);
setWalls(dungeon);
}
}
public void setRoomFloor(byte[][] dungeon){
origin = new Vector2(roomCornerDownLeft.x + roomWidth / 2, roomCornerDownLeft.y + roomHeigth / 2);
roomHeigth += 1; // +1 because of the WallBorders. So the Interior of the room is totally 5 tiles height
roomWidth += 1; // +1 because of the WallBorders. So the Interior of the room is totally 5 tiles width
roomCornerUpRight = new Vector2(roomCornerDownLeft.x + roomWidth, roomCornerDownLeft.y + roomHeigth);
for(int yPos = (int) roomCornerDownLeft.y; yPos <= roomCornerUpRight.y; yPos++){
for(int xPos = (int) roomCornerDownLeft.x; xPos <= roomCornerUpRight.x ; xPos++){
dungeon[yPos][xPos] = 1;
}
}
}
public void setWalls(byte[][] dungeon){
// Vertical walls
for (int i = (int) roomCornerDownLeft.x; i <= roomCornerDownLeft.x + roomHeigth; i++) {
dungeon[i][(int) roomCornerDownLeft.y] = 2; // North wall
dungeon[i][(int) roomCornerDownLeft.y + (roomWidth )] = 2; // South wall
}
// horizontal walls
for (int y = (int) roomCornerDownLeft.y; y <= roomCornerDownLeft.y + roomWidth; y++) {
dungeon[(int) roomCornerDownLeft.x][y] = 2; // North wall
dungeon[(int) (roomCornerDownLeft.x + ( roomHeigth ))][y] = 2; // South wall
}
}
但是我用它解决了一些奇怪的问题。放置“房间地板”没有任何问题。位置和大小刚刚好。但是当我试图在它周围建一堵墙时，它有时会起作用。这是一个例子:

它工作正常吧？所以现在让我们尝试使用其他一些值:

X位置= 20； Y位置= 25;
宽度 = 10； 高度 = 5;
如您所见，对齐不再正确了。墙壁位于与房间本身完全不同的位置……奇怪的是，只有当值(xpos、ypos、width 和 height)彼此不同时才会发生这种情况。
