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

[wilsonsilva]

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: https://bitbucket.org/rude/love/downloads/

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:(https://github.com/Ulydev/push)
