I'm having a spot of trouble trying to override the default LucasArts GUI, and I can't find any resources to explain why I'm having difficulty. I've replaced all the default art with simple Black/White replacements, (Not too hard of a task, but it helps the game's appearance stylistically) but for some reason the default GUI shows over the 9 command buttons, and the arrows on the inventory. Another issue is that I can't find anywhere to change the action(?) text that shows "Go ___" or "Look at ____" to be another color.
I've read the manual, and it didn't really give me the specific information I needed. Next, I checked the AGS wiki, but it's horribly out of date, and the information doesn't work in the version I am using. (3.3.5.7) The manual doesn't seem to say anything relevant either. I've changed both the "image" and "MouseoverImage" files, but nothing really seems to work.
I'm sorry if it's listed somewhere easy to find, but I've been looking for over an hour and couldn't find anything that would solve the issue. Thank you for your time, and I look forward to your responses!
EDIT: I did some snooping around in the default scripting and found both the place to change the sprites for the up/down arrows and the GUI elements! Mods can lock the thread.
Although the LucasArts GUI is included with AGS, it's not actually a part of the engine itself, which is why it's not documented in the manual. It's a module that has been developed by third-party contributors. The discussion thread for it is here: http://www.adventuregamestudio.co.uk/forums/index.php?topic=38874.0
