Canvas.copy passes unexpected "visible" keyword

edited March 7 in OpenSesame

Hi @sebastiaan,

Not sure whether this is a bug, or something related due to my trying to revive an ancient OpenSesame script in a newer version, but see below:

Error while executing inline script

item-stack: experiment[run].instructions_02[run]
exception type: TypeError
exception message: __init__() got an unexpected keyword argument 'visible'
item: instructions_02

    exec(bytecode, self._globals)

    return self.__class__(canvas, **properties)
TypeError: __init__() got an unexpected keyword argument 'visible'

Looks like `Canvas.__init__` is passed a `visible` keyword argument through `Canvas.copy`. For context, this is the relevant code from the offending inline script:

intro_mouse = mouse(self.experiment)
intro_keyboard = keyboard(self.experiment, keylist = ["space"])
intro_canvas = canvas(self.experiment)
intro_canvas_copy = canvas(self.experiment)


intro_canvas.text("Some instructions",center=False,x=64,y=64,color='black')
intro_canvas.text("Some further instructions",center=True,x=(self.get("width")/2),y=(self.get("height")/2 + 75),color='black')

intro_canvas.image("example.png", center=True, x=(self.get("width")/2), y=((self.get("height")/2)))



  • PS: What happened to the Markdown and/or html support?!

  • Hi Edwin,

    Right this is a known issue, but it has been fixed now.

    > PS: What happened to the Markdown and/or html support?!

    The new version of Vanilla (the forums software) has a new rich editor that allows you to apply formatting directly. However, it's a bit annoying that the `Markdown` functionality indeed seems to be gone. I'll see if I can re-enable that.



  • Ah, brilliant, thanks! I'll grab the latest code then :)
