Create the "game_assets.py" file
Create the "GameAssets" Class
Create the init() method
Use pygame.image.load() to load in game images
Use pygame.transform.scale() to change the size of an image
Create a method to combine the two functions above into one smooth process
Make use of default arguments in methods, in order to minimize the amount of typing/coding required.
Create a dictionary attribute, and fill that dicitionary with images, using a "for loop" and the newly created method
Import the game_assets.py file into the main.py file, in order to allow the Main class to create an instance of the GameAssets() object.
Run the game, ensuring no errors pop up.

Creating the "Game" object class11:55
Finally we at the point now where we can start coding the game into existence. The first thing we are going to create is the game object. The game object, and many of the other objects we will create will follow the same structure in terms of operation.
input()
update()
draw()
Many of the other methods we will create, will be called from within these three methods.
in the game class we create:
init()
input()
update()
draw()
Many more items will be created within these methods, but for now the base game is created.

As an aside, the reason why we are running the game in a class separate to the main class, is because the game moves through phases. We have a start screen, a game screen, and a level editor screen. So it will be easier to switch between the different phases in the main class.

Description

I have done so many of the regular projects out there, such as a tic tac toe, chess, hangman, asteroids, connect 4, but all of these projects felt small and I found there to not be much variety when it comes to game tutorials.

Most tutorials all cover the same games, with only variations in how they are coded. I also found that most tutorials, do not go through every element of a game, such as the start screen, all of the power ups, the score screens, etc.

They usually only take you as far as the basic building blocks, and then leave you to create the rest, should you wish to continue.
Most of these tutorials, have left me with a directory filled with what would be deemed as unfinished games.
Hence I thought it would be great to put together a course on creating a game, with all of the game elements created and implemented in a step by step process, that leaves you at the end of the course, with a fully functional, and complete game.

My hope is that you are able to understand how each element of this game is created and implemented, so that you gain further insight when deciding to tackle a challenge of your own.

I also find the old games from the 80's and 90's as fantastic coding challenges, in particular when it comes to trying to understand how something may have been implemented.

Who this course is for:

Python Programmers who have an understanding of python basics, but are looking to tackle projects bigger than tictactoe and hangman.
