Drawing shapes using code

[Minnfae]

I'd like to draw some simple shapes in my game using code instead of a bunch of pngs, to not increase the filesize too much. Is there a convenient way to do this? I remember doing this with a package called tkinter or something similar in pure python, but I'm still a bit confused with Ren'py.
By shapes I mean mainly circles and lines.

I guess it depends on your definition of the word "convenient," but yes, it's certainly possible to draw shapes. You're probably looking for canvas(), which can be used from an instance of the Displayable class within render. It somewhat matches the calls from pygame.

So you can use it a bit like this:

Code: Select all

class myDisplay(renpy.Displayable):
    def __init__(self, **kwargs):
        renpy.Displayable.__init__(self, **kwargs)

    def render(self, width, height, st, at):
            render = renpy.Render(160, 160)
            canvas = render.canvas()
            
            pointlist = self.get_pointlist()
            canvas.polygon("#003366", pointlist, width=0)
            
            canvas.line("#000", (80, 10), (80, 80))
            canvas.line("#000", (150, 45), (80, 80))

            return render

This would potentially create a canvas on which a filled blue polygon and two lines appear (except the pointlist method is undefined here, so it wouldn't quite work).

Ah, ok.
Yes, it's what I was looking for. Thanks a lot!
