something he doesn't cover: the .kv file has to be all lowercase. that was far too much work to figure out.

[demiz]

The .kv file is not being loaded, so for newer kivy versions u might need to load it eg.

def build(self):
Builder.load_file(pong.kv)
return PongGame()

[Stevesteacher]

Thanks dude, I love how you stop to explain everything

[safwenrejeb]

Bro YOU ARE A LIFE SAVER !!! The best tutorial so far on kivy

[burcakakiska]

If you are getting an error when running the code, try replacing:

PongApp().run()

at the end of the file with:

if __name__ == "__main__":
PongApp().run()

Note the double underscores before and after "name" and "main". Youtube comments may format them in weird ways.

You stated one thing wrong, the Co-ordinate system in kivy is unusual unlike pygame or other modules it doesnt start at top leftcorner, instead in KIVY, The (0, 0) or the starting index is at the bottom left corner.

[howtodo]

my app is not showing rectangle at the middle. it shows black screen although i wrote the full code

[CHRLY]

Hey dude, love your videos, it´s amazing how you explain very easy.

I have a question, when I run the game with the rectangle and the numbers, appears "kivy files require #:kivy !" and I don´t know what to do, 'cause that doesn't happen before, I could program the rectangle, but now I cannot do anything ):
Please, help.
(I use Visual Studio Code)

The editor treats my .kv file as a.py file and wants to "correct" it and doesnt automatically indent it like it does with .py files. does anyone know a reason why?

[azatnabiullin]

why do we write "self" first to refer to window size and later use "root" to refer to window size again? What is the difference?

[bohotsaaridhop]

why I have to name my kv file as pong or as the same name like my class object, is this some naming convention or its compulsory!

[tolkien]

In pyqt5, i can use qt designer for the design. Isnt there a designer in kivy similar to that?

[bartolofodac]

BEST TUTORIAL OF KIVY, nice work, congratulations

[sachinfulsunge]

For those who are having issues in creating .kv file extension, just write your code in any editor (ex - Notepad) and save it with an extension *All file ---> .kv

[youtubeuser]

My editor does not recognise the .kv extension

[weeb]

Getting error what must I do
AttributeError: 'PongGame' object has no attribute 'centre_x'

[TheNooBGuitarist]
