Wow chap 12 is a sever challenge almost look like a different languages, let’s keep up guys there we will learn I think we juste did our first step in the real coding 😅

[gotem]

really great walkthrough, the book is a bit dense and black and white syntax so this helps alot, thanks!

Hello, I hope you are doing well, I trying to run the program at 17:19, but I received an error that I do not understand. The error is:

ALSA lib pcm.c:8424:(snd_pcm_recover) underrun occurred

Do you know what this means, if so, can you explain it to me?
Thanks

I notice that from chapter 1 to 11 all was having fun. This chapter all comments are having troubles. Chapter 12 has several challenges. From installing the pygames on the start the book installation syntax is out dated search for updated syntax in youtube you will know if your successful if you can import the pygame. The code is importing the major class from pygames this disappointed me but the main class is still very long. Due to the long code we forgot to check the indentions and a simple missing _ can be major head ache. Some lines also confusing because of the refactoring on this event some moves from other class and some is added. Some code was replace like the screen zoom. I was hoping to code the actual movement of the ship, hoping for the next project to be more hardcoding rather than importing 50% of the function form class package.

I can't run the game at all, the moment I try running the alien_invasion.py, I get an error saying that video system not initialized. And I have no clue how to solve it. Can you please help?

I don't understand how you come to the process at mark 13:47 - 13:51. I created at images folder with alien_invasion folder and I am receiving an error stating that the file cannot be found.

Hello sir! i am reading the chapter 12 of this book and i am getting continuos error for ship.bmp file that it is not found in directory please help in this regard

[erwindnfire]

Great video this chapter is really challenging.

Hi, you write the method bullet.update(), but the Sprite class also has it.
In this case, will Sprite's method take any effect or it will have no affection at all? (I don't understand about override method in this case)

[sergiorodriguez]

I keep receiving no file found in directory. Pls help

[darkknight-fceq]

Can you please tell me how you got the ship image

[neilpastilan]

Good day, how about test yourself 12-5 keys

[kareburedgamer]

I’m having issues with the ship.blitme() and the run_game() lines so I’m using this video to see if I done anything wrong

[Matviikh]

My ship is visualised almost on a full screen. How to make it smaller?

[sarthakshelar]
