2D阵列 - 错误的“墙”放置？

Question

晚上好，圣诞快乐！

我想制作自己的Dungeon-Generator。因此，我决定首先在一些空房间中产生，同时将墙壁放置在同一个步骤中。

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

    }

}

但我接近了一些奇怪的问题。放置“房间地板”没有任何问题。位置和大小是正确的。但是当我试图围绕它建造一堵墙时，它有时只会起作用。下面是一个例子：

1 =楼层 2 =墙

Xposition = 25; Yposition = 25;

宽度= 5; height = 5;

它工作得很好吗？所以现在让我们尝试使用其他一些值：

Xposition = 20; Yposition = 25;

正如你所看到的那样，对齐正好了。墙壁位于房间本身以外的其他位置....奇怪的是，这只发生在值（xpos，ypos，width和height）彼此不同时。

坐标和尺寸与上面的示例相同。

我的代码中存在问题？通常墙应该在房间周围......

Answer 1

在setRoomFloor方法的内部for循环中，您将反转x轴上的位置和y轴上的位置。

dungeon[yPos][xPos] = 1;

应该是

dungeon[xPos][yPos] = 1;

Answer 2

我终于得到了解决方案，我的Wall Algorythm被打破了，我写了一个新的：

  // Vertical Walls 
  for(int y = (int) roomCornerDownLeft.y; y <= roomCornerDownLeft.y + roomHeigth; y++){

      dungeon[y][ (int) roomCornerDownLeft.x ] = 2;

      dungeon[y][ (int) roomCornerDownLeft.x + roomWidth ] = 2;

  } 

  // Horizontal Walls
  for(int x = (int) roomCornerDownLeft.x; x <= roomCornerDownLeft.x + roomWidth; x++){

      dungeon[ (int) roomCornerDownLeft.y ][ x ] = 2;

      dungeon[ (int) roomCornerDownLeft.y + roomHeigth][ x ] = 2;

  }
