[Mescalino]

Not sure what i have done or how to fix it.
Deos anyone have a clue or a direction i should go. Thanks

I'm sorry, but an uncaught exception occurred.

While running game code:
Exception: DynamicImage [u'gui/button/navigation_[prefix_]background.png', u'gui/button/[prefix_]background.png']: could not find image. (u'gui/button/navigation_idle_background.png', u'gui/button/navigation_background.png', and 2 more.)

getting the feeling im missing some files....

 

[Mescalino]

problem solved for some reason i was missing a lot of gui images.

Hi! I'm having the same problem with RenPy. Could you tell me how did you solve it??

Hi! I'm having the same problem with RenPy. Could you tell me how did you solve it??

In the original case, they were missing some image files.

If you look at the bottom of the exception list, you'll see the line:

Exception: DynamicImage [u'gui/button/navigation_[prefix_]background.png', u'gui/button/[prefix_]background.png']: could not find image. (u'gui/button/navigation_idle_background.png', u'gui/button/navigation_background.png', and 2 more.)

Breaking that down a bit...

Exception: DynamicImage

[u'gui/button/navigation_[prefix_]background.png', u'gui/button/[prefix_]background.png']: could not find image. 

(u'gui/button/navigation_idle_background.png', u'gui/button/navigation_background.png', and 2 more.)

So the game was expecting to find some specific files in the /game/gui/ folder and couldn't.

In this case, the dev was using filenames with variables in the middle (the [prefix_]). So it could be the variable was wrong. But based on the reply, it looks more like either the files weren't there at all - or weren't in the correct folder (probably in /game/images/ instead of /game/gui/.

If you're seeing similar messages... then the cause is likely similar too. Files missing, files incorrectly named or files stored in the wrong folder.

As a suggestion... Start the RenPy Launcher, select your project and run "Check Script (Lint)" under the "Actions" lists near the bottom center of the window. It will check your code as best it can and tell you about any potential problems... including the names of files that might be missing. As an automated tool, it's not as good as actual testing... but it's really good at catching this sort of stuff before it becomes a serious issue.

Hi! Thx for explaining it, I'm a newbie in RenPy, so very appreciated.
I checked the game directory and couldn't find any other images outside "gui", not even in "images". In the end, I just copied some images from the demo project and copied them to the game directory, and voila, no more error. Tho, even if I fixed the problem temporarily Renpy will keep creating projects without some assets. Guess I'll just have to cope with that.
