Changing the characters (actualy on background) expression after dialog option.

[Revan]

Hi again, I was wondering if it is posible to do this;
I have a character who isnt actualy a character he's part of the background (All my objects and characters are in this game) and I want it so when a dialog option is said his expression changes (the only way I could think to do it would be to draw over the origional background and make it as a new room, I have done this but cannot get the dialog option to send you to the room) can anyone help me? (Im crap at scripting dont even know how to use variables)

You could just make an object - originally not visible - the new expression of the character, place it on the right spot on the background and when their expression should change, make the object visible.
