[SOLVED] Error when displaying Live2D on a screen: NoneType object is not iterable

[chocojax]

When I try to display a Live2D model on a screen, I keep getting a NoneType error. It displays fine in the actual script when I test it out.

The way I'm trying to implement it:

Code: Select all

screen about():

    tag menu
    ## This use statement includes the game_menu screen inside this one. The
    ## vbox child is then included inside the viewport inside the game_menu
    ## screen.
    use game_menu(_("About"), scroll="viewport"):

        image Live2D("live2d/Chocojaxv2Default")

Error:

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
TypeError: 'NoneType' object is not iterable

Adding a Displayable to a screen is not done using the keyword "image", you have to use "add".

Code: Select all

add Live2D("live2d/Chocojaxv2Default")

add Live2D("live2d/Chocojaxv2Default")

I've tried that too, still the same error with NoneType object is not iterable.

You will need to define your Live2D displayable first, outside of the screen.

Code: Select all

image test = Live2D("images/test.model3.json")

screen MyScreen():
    add "test"
