With this function you can load a game state that has been saved previously. The game is loaded from a previously created "grow" buffer (see Buffers) and the buffer must have had a game state saved to it using game_save_buffer function.
|buffer||The buffer id to load from.|
if global.Checkpoint game_load_buffer(save_buff);
The above code will load a previously saved game state from the buffer indexed in the variable "save_buff", only if the global variable is true, when the player presses the "L" key.
