how to draw rectangles in a circle? ('Legacy' object has no attribute error)

bssengul

Hello,

For a working memory task, I make 6 photos appear in a circle at 60 degree angles. After this stimulus presentation, I am trying to draw 6 empty, white framed rectangles at the angles at which these 6 photographs appear. I also want to have the numbers "1","2","3"..."6" one by one inside these rectangles. These rectangles will be presented, and then participants will choose the location of the photos they just saw. I'm trying to draw rectangles in circles, but the code I wrote doesn't work. Can you help me to solve the problem?

Thanks in advance.

Here is the error code I got:  File "C:\Program Files (x86)\OpenSesame\Lib\site-packages\libopensesame\inline_script.py", line 92, in prepare

  self.workspace._exec(self.cprepare)

 File "C:\Program Files (x86)\OpenSesame\Lib\site-packages\libopensesame\base_python_workspace.py", line 124, in _exec

  exec(bytecode, self._globals)

 Inline script, line 41, in <module>

AttributeError: 'Legacy' object has no attribute 'canvas'

Hi @bssengul ,

The issue results from these lines:

rectangle1 = Canvas ()
# ...
# Dikdörtgeni çizme
for i in range(num_rectangles):
    rectangle1.canvas.rect(left=var.x[i], top=var.y[i], width=rect_width, height=rect_height, 
                        fill_color='', line_color=rect_color)

First, you're creating a Canvas object called rectangle1 . Next, you're trying to access rectangle1.canvas as though rectangle1 , which is itself a Canvas , in turns has canvas property inside it, which it doesn't. Do you see the conceptual mistake here?

More generally, I would first walk through the intermediate Python tutorial to familiarize yourself with the basics of using Python in OpenSesame:

• https://osdoc.cogsci.nl/3.3/tutorials/intermediate/ (for v3.3)
• https://osdoc.cogsci.nl/4.0/tutorials/intermediate/ (for v4.0)

Hope this helps!
