====== BlockGame() ======

===== Syntax =====
''BlockGame(void);''

===== Description =====
The command blocks the user interface and the AI work as well as the camera management. This way, the world comes to a stop, and the script remains as the only source of in-game events. The command also stops the running heroes (while preserving their paths). To unblock the game, the [[UnblockGame()]] command should be used. Game blocks are accumulated, which means that the game will be unblocked once the number of calls for [[UnblockGame()]] will be equal to that of BlockGame().
