Games50 (pong): attempt to call field 'getPixelScale' (a nil value)

If you're taking the course Games 50 from edX/Harvard and you're getting the error:
Code: Select all
attempt to call field 'getPixelScale' (a nil value)
It is because you're using love version 0.11 or greater and the method
getPixelScale, used by the
push library has been renamed to
getDPIScale. Please use version 0.10.2. It can be downloaded here:

Wouldn't it be better to use a fixed version of push? This is fixed since May.

Replacing getPixelScale with getDPIScale in push.lua fixes the problem. Or you could replace push.lua with an up-to-date version.

Great lord Necropost, we thank you for the much needed input,
not like it has never been mentioned above.

I suggest to replace push library with an updated one because getDPIScale gave me some other problems. So I used this:(
