Hello all. So in my game I want to display side-images next to the dialogue box, and I have a lot of side-images that I sometimes add more to. My usual procedure when adding a new side-image is to reload Ren'Py, start a new game, and then play through to see if it works. Recently I added a few new side images, but unfortunately, I keep getting a 'Switch Cannot Choose A Displayable Image'. Here is the code in question:

Code: Select all

    
init:
    $ flash = Fade(.25, 0, .75, color="#fff")
    $ redflash = Fade(.25, 0, .75, color="#FF0000")
    $ mood = 0
    $ e = Character('Parker', color='#009933', \
        show_side_image=ConditionSwitch('mood==0', 'par_smile', 
        'mood==1', 'par_surp_frown', \
        'mood==2', 'par_smile_talk', \
        'mood==3', 'par_frown', \
        'mood==4', 'par_blush_smile', \
        'mood==5', 'par_open_mad', \
        'mood==6', 'par_surp_smile', \
        'mood==7', 'par_blush', \
        'mood==8', 'par_sheep_blush', \
        'mood==9', 'par_determined', \
        'mood==10', 'par_norm_frown', \
        'mood==11', 'par_closedeye_blush', \
        'mood==12', 'par_lidded_blush_smile', \
        'mood==13', 'par_sleepy', \
        'mood==14', 'par_sleepy_frown', \
        'mood==15', 'par_crying', \
        'mood==16', 'par_bitter', \
        'mood==17', 'ke_frown', \
        'mood==18', 'ke_smile', \
        'mood==19', 'ke_surp', \
        'mood==20', 'ke_open_surp', \
        xalign=0, yalign=1.0), window_left_padding=210)

label start:
        $mood = 17
        e "Test"

So everything up to Mood==16 works. I recently added the four 'ke' images and went about the process of restarting the game and starting a new game. However, when I try to switch to that mood, I get a 'Switch cannot choose a displayable' error. For those who are interested, here is the stacktrace:

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/script.rpy", line 189, in script
    e "test"
Exception: Switch could not choose a displayable.

If anyone has any insight, I would seriously appreciate it. Thanks everyone!

I'd suggest adding code like:

Code: Select all

define e = Character('Euls', color='#009933', \
        show_side_image=ConditionSwitch('mood==0', 'eul_smile', 
        'mood==1', 'eul_surp_frown', \
        'mood==2', 'eul_smile_talk', \
        'mood==3', 'eul_frown', \
        'mood==4', 'eul_blush_smile', \
        'mood==5', 'eul_open_mad', \
        'mood==6', 'eul_surp_smile', \
        'mood==7', 'eul_blush', \
        'mood==8', 'eul_sheep_blush', \
        'mood==9', 'eul_determined', \
        'mood==10', 'eul_norm_frown', \
        'mood==11', 'eul_closedeye_blush', \
        'mood==12', 'eul_lidded_blush_smile', \
        'mood==13', 'eul_sleepy', \
        'mood==14', 'eul_sleepy_frown', \
        'mood==15', 'eul_crying', \
        'mood==16', 'eul_bitter', \
        'mood==17', 'ke_frown', \
        'mood==18', 'ke_smile', \
        'mood==19', 'ke_surp', \
        'mood==20', 'ke_open_surp', \
        'True', Text("[mood]", size=100),
        xalign=0, yalign=1.0), window_left_padding=210)

The define (which should be at the top level, before label start, replacing the $ e = line) will ensure e is defined at init time. I don't know if this is the problem, but it's possible e is being saved and loaded, which could cause this problem. Remember to start a new game.

The 'True' line will mean that if no other condition is chosen, the number of the mood will be displayed - which should tell us something about the problem, if the former code doesn't fix it.

Hmm I do that in the init block and I still get the same error...where is the number of the mood supposed to be displayed?

It should be displayed on the screen, where the character would be.

Are you starting your game over? You need to, since your old savegames have the e character saved in them.

Yeah I deleted my persistent data and started a new game, but I'm still getting the error. Not quite sure why the init block is being so finicky...

EDIT: I also tried changing mood=16 (which works) to ke_frown, but it still displays par_bitter. I also tried swapping it out for 'par_crying', but it still displays par_bitter even if I start a new game and delete persistent data.

Can you post your full code somewhere? I'm having trouble understanding what's wrong.

Posted: **Sat Jan 17, 2015 9:27 pm**

EDIT: Wait, nevermind. I fixed it. I think the problem was that I have two inits in two different script files and I think that perhaps the other init is taking precedence over the init in script.rpy. Thanks for the help!!
