If I want to change graphics of the load and save default windows, must I create a new GUI?
Isn't it possible to change the default windows?
Yes and No, in that order.
(By which I mean: It's not possible to alter the appearance of the hard-coded Save/Load windows, you will have to make new GUIs for them. However, it's not that hard, there are many threads on the forums dealing with them and - again - modules for the more complicated stuff like Savegame Screenshots.)
EDIT: The only thing you can change is some of the text ('Select a game to restore' 'Save', 'Restore', 'Cancel', etc), which is stored in the Global Messages.
OK thank you, I understand.
So, I have to create a new GUI. I red the manual, but I don't know how to begin to create the save and load windows. Where can I find some information?
A forum search (http://www.adventuregamestudio.co.uk/yabb/index.php?action=search) for 'Save GUI' or something similar would be a good start...
EDIT:
Thank you, Joel. For some reason I couldn't find that tutorial earlier.
this tutorial helped me out a lot.
