Working out the details for the Gallium Games recruitment event/competition we mentioned at the start of the year.

Ren’Py Android purchase

By default, when you want to make an in-app purchase on a Ren’Py game, you’ll see a black screen as the Google purchase pop-up appears.

black background, google play pop up asking if you want to make an in-app purchase

Because DMR uses some extra layers, this breaks things. During out betas, our testers found stars floating around (the button we use to open/close the quick menu). The same thing happened here.

It took a little digging around in the source code of Ren’Py to find out where that black screen was coming from.

In 00iap.rpy, we have:

init -1500 python in iap:

    from store import persistent, Action
    import time

    background = "black"

def with_background(f, *args, **kwargs):
    Displays the background, then invokes `f`.

    if background is not None:


    return f(*args, **kwargs)

We don’t want to call renpy.scene() because it breaks with floating stars, so we just have to define background = None.

init -1000 python in iap:
    background = None

We set the priority to some number -1500 so that we overwrite the initial variable value. We also have to make sure to put the variable under the scope of iap.
