Question about "layered sprite" cookbook entry

[Qu-ko]

...Um, hi, long time no post?

Anyway, I've just been fiddling around with Ren'Py lately, not really working actively on anything, mostly testing stuff out. And I've been trying to work the "layered sprite with different emotions" cookbook entry, but I seem to be having trouble. Knowing me, it's probably something very simple that I'm missing, but I think it has something to do with not turning off the sprite and then trying to go back to the main menu that's making it crash?

This is the code I'm using:

Code: Select all

init:

    image rei = ConditionSwitch(
            "rei_face == 'happy'", LiveComposite(
                (200, 256),
                (0, 0), "rei-body.png",
                (96, 88), Animation("rei-eyes11.png", 2.5,
                                                "rei-eyes12.png", 0.05,
                                                "rei-eyes13.png", 0.05,
                                                "rei-eyes12.png", 0.05),
                (112, 136), "rei-mouth1.png"
                ),
            "rei_face == 'sad'", LiveComposite(
                (200, 256),
                (0, 0), "rei-body.png",
                (96, 88), Animation("rei-eyes21.png", 2.5,
                                                "rei-eyes22.png", 0.05,
                                                "rei-eyes23.png", 0.05,
                                                "rei-eyes22.png", 0.05),
                (112, 136), "rei-mouth2.png"
                )
            )


    $ rei = Character('Rei', color="#5c628b")


label start:
    
    show rei
    $ rei_face = "happy"
    with dissolve

    rei "You've created a new Ren'Py game."
    
    $ rei_face = "sad"
    with dissolve

    rei "Once you add a story, pictures, and music, you can release it to the world!"

And this is the traceback:

Code: Select all

I'm sorry, but an exception occured while executing your Ren'Py
script.

Ren'Py Version: Ren'Py 6.9.3c

...Probably should've attached those, but it's easier this way. :<

Um, so, there is clearly something my simple mind is missing here. Help?

[Melkoshi]

Seems to me you left out a start for the rei_face veriable.

It needs to know what ti is, before it can be changed. makes sense?

so if you add a $ rei_face = happy in your init, it should work. and then change when you change the happy to other emotions.

[Heatth]

You could also add a "rei_face == 'None'", rei-body.png) to the ConditionSwitch, as it is said at the cookbook. Then it woudn't crash. (it woudn't appear any face until you define rei_face either, of course)

I think it was actually the init block $ rei_face = "happy" that I needed to make it not crash, since I'd had the "rei_face == 'None'", "rei-body.png" in the ConditionSwitch and it still crashed every time the game ended, so I took it out to experiment with why it was doing that.

Thanks, ahaha. *dumb*

Code: Select all

label start:
    
    show rei
    $ rei_face = "happy"

The problem was here. See, you tried to show <rei> before tell the Ren`py what condition she is.
So, you might set the <rei>s condition in init block, as Melkoshi said, or just change the order of lines like

Code: Select all

label start:
    
    $ rei_face = "happy"
    show rei

anyway, if you add new condition it should works like the others.
