Problem with Love: Pong 2 and beyond

[VoidGamer220]

I was greeted with the following upon running Pong 2:

Error

push.lua:101: attempt to call field 'getPixelScale' (a nil value)

Traceback

push.lua:101: in function 'initValues'
push.lua:48: in function 'setupScreen'
main.lua:49: in function 'load'
[C]: in function 'xpcall'
[C]: in function 'xpcall'

I ran the other pongs and only pong1 and pong0 are unaffected. It seems to be a problem with getPixelScale, perhaps the system has changed so that this part of the code is less viable?

Had the same problem, what happens is that 'getPixelScale' ceased to exist in love above version 0.9. So if you are using a version higher than 0.9, (you probablly got version 11.x) you should use 'getDPIScale'.

I did a full "Replace all" on this function using vscode and had no problems with this function anymore.

Another problem that i had was about #8, wich thankfully @09jlardinois already found an answer and I didn't have to dig around for days to find a solution like him.

See love2d wiki on "Renamed APIs" section

Hi, maybe you need to update push.lua to the latest version -> v0.4
https://github.com/Ulydev/push/blob/master/push.lua

I have another issue with a completely white screen with nothing on it

I get the same issue @phervas as I've updated the push.lua
and then sorted the error with 'getPixelScale' substituting 'getDPIScale'
Now all I have is white screen

Hi @Fiain, apparently there was a change in Love somebody mentioned at some other post. What worked for me was do divide the first 3 values at love.graphics.clear by 255:

love.graphics.clear(40/255, 45/255, 52/255, 255)

I can confirm that the solution works. Just upgraded to Love 11.3, push.lua v0.4 and changed the following line in the code and I got back the rendering instead of the white screen:

love.graphics.clear(40/255, 45/255, 52/255, 255/255)

I have tried this one love.graphics.clear(40/255, 45/255, 52/255, 255/255) and got it but the other issue is I am not able to see the ball and the second paddle.

[srisowmya2000]

my code is

@srisowmya2000 in the love.graphics.clear function just do this and it will work:

love.graphics.clear(40/255, 45/255, 52/255, 255)

and similarly in the love.graphics.printf:

love.graphics.printf('Hello Pong!', 0, 20, VIRTUAL_WIDTH, 'center')

you aren't able to see the right paddle and ball as you are rendering only half the virtual width minus 6 dimensions whereas your ball and right paddle are being placed in the non-rendered area

@Yaugan thanks for helping me out. But I still am getting an error.
