As a command to completely open the map, the Black Sheep Wall can be used as a special cheating code or cheating command in some games (such as StarCraft). When the player enters the "Black Sheep Wall" in the game, it will activate a function that enables the player to see the whole map, not just their current position or the area in the field of vision. Please note that the use of this secret command may change the balance and challenge of the game, so it is not recommended to use it in the formal competition or challenge mode of the game. It is more suitable for single-player games or test environments, so that players can better understand the map layout and resource distribution. As for why "Black Sheep Wall" is chosen as the instruction of this function, it may be related to the personal preference, creativity or some internal agreement of the game developer or designer.
