Chapter 6: Challenges!

LEVEL 1

Very easy

12 / 20

The goal of this first challenge is to replace the spritesheet rabidja.png with rabidjette.png . 

You can download it above and it will be useful for all 3 challenges.

Tips: Copy the file to the right place, along with the other one.

In Constants, change the name of the file .

And it's good! 😸

LEVEL 2

Easy

14 / 20

You will take the previous code after having it validated by your teacher. 🙃

Now you will change the keys to move Rabidjette:

• The left arrow will be replaced by the Q key .
• The right arrow will be replaced by the D key .
• The c (jump) key will be replaced by the SPACE key .

Everything will happen in the Main() file .

Look for key detection and replace the old key code with the new one .

To find the code for the new keys, you will use the Pygame documentation here .

LEVEL 3

AVERAGE

20 / 20

Well, this is a bit more complicated, but for a 20/20 , it's worth a try, right? 🙀

We'll have to add a second player! 😅

We will therefore have two players simultaneously on the screen: Rabidja and Rabidjette.

Each player will start at one end of the map (left and right).

Player 1 will move with the keys: Left/Right Arrows + Right Shift.

Player 2 will move with the keys: Q / D + SPACE bar.

For this tutorial, you will have to reuse techniques from the two previous challenges .

You will need to load the two spritesheets : rabidja and rabidjette .

Creating a second player may seem complicated, but it's actually very simple thanks to our class system ! 😎 All you have to do is:

     player1 = Player(1)
     player2 = Player(2)

In our Player class, we will need to retrieve the player number to load its correct spritesheet like:

class Player :

    def __init__ (self, PlayerNb ):
         # Load sprite file based on player
         if PlayerNb == 1:
            self.sprite =     
                pygame.image.load(SPRITE_PLAYER1).
                convert_alpha()
         else: ....

Then, once we have our two players, we can test the keys using player1.input or player2.input (easy!! 🤪)

Likewise, for updating or displaying sprites, simply do:

    #We update player 1 then 2
    player1.update()
    player2.update()

Okay, come on, I'll let you search for the rest, I'm not going to tell you everything either! 😅
