flappy | A Python graphics library -

I wanted to write a flappy bird game in javascript but it doesn't seem to work when I open it in my browser. the css works. lines 147, 154, 31 and 160 in js all seem to be errors, but I do not understand how to fix them.

this is my html:

So, I found a video of Tech with Tim, where he was creating a flappy bird py file.. Well, my issue is the pygame window in not popping up after running it. I'm using ubuntu 20.04.. Searched for solutions, and mixed all I've learnt since I'm a complete beginner in pygame.. need help :(

I'm a beginner in unity and programming, I was following a video for making a Flappy Bird game. Everything works perfectly but when I run the game, I get a floppy disk icon middle of the screen and somehing called DontDestroyOnLoad starts working out of nowhere. I couldn't find or understand anything on google when I search for it. I'm posting the screenshots in case anybody wanna see it.

This icon and dontdestroyonload thing only appears when game is being run:

So I trying out lwjgl but I'm having a problem, when I try to create a window I get an error I just can't figure out why.

I have tried to lower my java version from java 16 to 14 but that didn't work.

Main Class:

I am making a sort of flappy bird game and have made the pillars as new components that appear at different lengths according to Math.random(). But even though I can change the colors of these pillars i really want to add a box-shadow on them, just to make it look cool. It's not really necessary. So, if anyone could let me know if I can even add a box-shadow to a component or not would be helpful as well. Here's the code for the pillars if you want to have a look:

I have a file I'd like to parse to json. First item looks as follows:

I've been following the python flappy bird ai tutorial from techwithtim, and I get this error;

Ok, so I'm building a flappy bird clone for a class, the game is being built in HTML using Canvas and Javascript. I'm pretty new to JavaScript and I've hit a bit of a snag. I have a working game, but it is of fixed window size and I would like to scale the game as the user scales their window.

My working fixed scale game is this

I'm making a flappy bird-like game. The problem is, the images do not load in the loop within the draw() function. If I were to put the drawImage()'s outside of the loop (like the rest of the images), then they would work.

No errors in the console, the two images inside the for loop do not appear and I just don't understand why >:/
