Make a python code for Main topics: keyboard input, Pygame library, coordinate transformations

In an Asteroids arcade game you are the commander of a spaceship which got caught in

an asteroid cloud. Luckily your spaceship is equipped with lasers so you can pulverize

the asteroids before they hit you. For the Asteroids game see the Wikipedia entry on the

original Asteroids game of Atari. For more information on real asteroid clouds see the

NASA article on the Kuiper belt

Task description of the project:

Figure $2$: Screenshot asteroids game example

Draw some images to use for your ship and asteroids

During the game the spaceship is in the center of the screen

The spaceship can rotate itself to shoot asteroids with a laser

Asteroids fly in random directions $($potentially harming the ship$).$ Not all asteroids

will hit the ship.

To obtain a graphical window, and facilitate keyboard interactions, you will use Pygame,

a Python package dedicated to making games in Python, see the Pygame website.

A few more hints to get you started:

To start off with your project have a look at the Pygame documentation: start with

the example at the beginning and then add the functionality for your game.

Loading an image $($asteroid image, spaceship, etc.$)$ and scaling it to the right size

$($to use inside the game$)$ can be done using:

Rotation of images can be done using:

im$\_$ship$\_$rot $=$ pygame.transform.rotate $($surface$=$im$\_$ship, angle$=$angle$)$

The y$-$axis of the screen is pointing down, you can create functions to convert

between screen coordinates and the game coordinates $($where the ship is in the

origin$).$

To put an image on the screen you use $($realize that the destination parameter uses

the location of the upper$-$left corner of the image, you need to correct for this for

the image of ship or asteroid to be in the middle$)$

screen.blit$($the$\_$image, dest $=(x,y)$

A rotated image is larger than the original, so the center point is different, so every

time you rotate your ship you need to recalculate its center point.

Check for collisions between ship and asteroids at each time point. Calculate the

distance between the spaceship and the asteroids and verify whether this distance

is large enough.
