Thank you very much for your attention, that was very helpful but I have a little doubts left. I used quicksave\quickload system and it worked in the game(when the character fell down from the hill it came back on the top of the hill) but when i closed the game and open it again, it started from the begining of the game. How can I make my character start from the top of the hill(not from the begining of the game) when i close the game and start it again. Also in the save/load to disk system which file should I write for the "file" part.
Thank you again...
