showing a scene with a variable scene image name

[Pyro]

Hi guys
I just want to ask about using variables for scene image names.
My project has been getting quite large now so I want to bring things together into classes.

I have a particular environment object declared like this

Code: Select all

$Camp = Environment("Camp", renpy.image("bgCamp", "environments/camp.jpg"), 0, True, False)

I want to be able to do something like this

Code: Select all

scene Camp.background with dissolve

What would be the best way to go about this?

My environment class is defined like this

Code: Select all

class Environment: 
            def __init__(self, name, background, discoveryScore, discovered, visitable):
                self.name = name                        # The name of the environment
                self.background = background            # The background image
                self.discoveryScore = discoveryScore    # The score needed to discover the land
                self.discovered = discovered            # Wether the land has been discovered or not
                self.visitable = visitable              # If the land can be visited or not
                    
            # Discover the environment
            def discover(self):
                self.discovered = True

Thanks a lot!

I'm sure it's hamfisted, as opposed to elegant, but you could try adding:

Code: Select all

$ renpy.transition (dissolve)
$ renpy.pause (1)

before you call your scene in the script. That should force the dissolve transition and the pause should give it enough time to play before the scene loads.

Hey there, thanks for the quick response.

Its not really the effect I was looking for help with, more actually getting the scene to show in the first place. I probably should have not included the effect in my example.

Currently if I use "Camp.background" in place of say "bgCamp" then I get an "end of line expected" error.

Code: Select all

File "game/scripts/chapters/Chapter 1/intro.rpy", line 10: end of line expected.
    scene Camp.background
              ^

I was wondering if there was an elegant way to use variables for the "scene" keyword/function.

perhaps:

Code: Select all

scene expression Camp.background with dissolve

[Pyro]

Awesome, that sort of works!

If "Camp.background" contains a renpy.image() then I get a "Not a displayable: None" exception.
However. If I point it to something like "Camp.name" and make that the same as the graphic name then it will work.

So I am guessing

Code: Select all

scene XXX

wants XXX to be a string relating to a stored image rather than the image object itself.

[PyTom]

renpy.image returns None, it just registers the image name. If you make it an Image, that will work. (Using a string is better, since you generally don't want to use direct references to Images in code that will be saved.)
