Anti-aliasing for online experiments using Builder?

If this template helps then use it. If not then just delete and start from scratch.

OS (e.g. Win10): Linux
PsychoPy version (e.g. 1.84.x): 2020.2.3

What are you trying to achieve?:
the Bulder automatically opens the window with UseFBO = True, MultiSample=False, and numSamples=2. I intend to run the experiment online. My experiment has a visual stimuli comprised of a rod oriented at specific angles from vertical. With the window created by Builder the rod edge looks chappy. After I compile my experiment, in Coder, I changed the useFOB=False, multiSample=True and numSamples=16 and the rod edge looks great. However I can not convert the coder code to PsychoJS. So is it any way to control the anti-aliasing from the Builder? I uploaded the project on pavlovia and the edge looks chappy there too. I thought the PXI renderer might do something different, but no.
Thank you

You can insert a Code component in Builder, which allows you to inject code at certain points. If you do the same thing you did in Coder via a Code component instead, then it should be translatable to JS and run online

The documentation says that you can not change multiSample property of a window after opening. So in this case the code will not be helpful.

Ah I see, I’ll chat to Jon about whether we need to add in these parameters to the Experiment Settings dlg then, as currently I can’t find any way to do this in Builder

Hi @TParsons, that would be great. Changing multiSample and numSamples in my code fixed a problem I was having in Coder but I need to migrate to Builder now and do the same thing.

Hi, with the Builder, I don’t have this problem.

Hi, is it now possible to change the multiSpample properties in the Builder?
