Projects in Python: Get started with Python game development

Create an alien class to represent an alien and load its bitmap from the resources images folder. Initialize starting position near the top-left and draw it at its current position.

Learn to create an alien instance by importing the alien class, instantiating it in the game loop, and updating the screen to render the aliens, ships, and bullets.

Learn to render an alien on screen by invoking the blit method from the main file, and see bullets and aliens appear as you progress toward building the alien fleet.

Learn how to compute the horizontal space for aliens, set margins and spacing, and build a fleet as a group of aliens, then update and draw the fleet on screen.

create a fleet of aliens by defining a create_fleet function, importing the alien class, and positioning a calculated row of aliens on screen.

Refactor the game’s fleet creation by extracting tasks into new functions, such as creating aliens and computing how many aliens fit in a row from Titan settings.

Learn how to compute the number of rows that fit on the screen and generate a multi-row alien fleet with nested loops and spacing based on alien and ship heights.

Learn how to move aliens to the right by updating each alien’s x position with a speed factor and wiring an update_aliens function into the game loop.

Detect when alien fleet hits screen edge, switch direction using 1 for right and minus 1 for left, and apply a drop speed to move the fleet down and left.

Learn how to make the alien fleet drop and reverse direction when it reaches the screen edge by implementing check_fleet_edges and change_fleet_direction, and by updating each alien's position accordingly.

Learn to implement collisions in Python game development by detecting bullet and alien overlaps with a sprite group collide, removing bullets and aliens when hit, and updating gameplay accordingly.

Learn how to repopulate the alien fleet in a Python game by detecting when the alien group is empty, clearing bullets, and spawning a new fleet of invaders.

Modify the settings to adjust alien and bullet speeds, changing from one to two, and tweak the drop down speed to make the game more challenging.

Detect alien ship collisions by using sprite collide in the update aliens function, and print your ship has been hit to drive the end of the game.

Add a check for aliens reaching the bottom of the screen and call the ship hit logic when triggered, then update alien positions and spawn a new fleet.

Add a game_active flag and guard ship_hit with a ships-left check to bring the Python game closer to completion. End the game when ships run out.

Identify which parts of the game should always run versus when the game is active. Always call check events and update the screen; other code runs only when active.

Create a reusable button class to render a rectangle with a label and add a play button to start the game, paving the way for a scoreboard and lives indicators.

Create and render a play button by importing the button class, instantiating play_button, and drawing it after all game elements on update when the game is inactive.

Learn to wire a clickable play button in pygame by monitoring mouse events, detecting clicks on the button with collidepoint, and starting the game by setting the game_active flag.

We reset the game by clearing aliens and bullets, reinitializing stats and ships, and creating a new fleet centered on start, so a fresh game begins after each end.

Deactivate the play button to prevent resets when you click the screen, and restart the game only if the play button is clicked and the game is not active.

Hide the mouse cursor during gameplay with pygame by calling pygame.mouse.set_visible(false) and reveal it again when the cursor moves over the game window, enabling a clean play screen.

Increase game tempo by leveling up: adjust speed settings with speed up scale, initialize dynamic settings, and raise ship, bullet, and alien speeds as levels advance.

Reset the game settings to their initial values when starting a new game, so aliens, bullets, and ship speeds restart. Each new level increases speeds for a more challenging experience.

Learn how to add a scoreboard to a Python game by initializing score to zero, rendering it as an image, displaying it in the top-right, and updating it during play.

Learn to assign points to aliens, initialize scores, and update the scoreboard after each bullet-alien collision to track progress in a Python arcade game.

Increase point values as the game speeds up by multiplying alien points with a score scale, and handle the collisions dictionary to award points for every alien hit.

Learn how to round a game score in Python, convert it to a display string with formatting, and render it, using a negative round argument to align to tens.

Add a persistent high score to the game by initializing a high score, rendering its image, and updating it after each collision using a new check_high_score function.

Import the ship class, instantiate the ship before the main loop, and render it on the background, then debug errors and prep for piloting.

Add a current level attribute to game stats, render a level image, and display it on the scoreboard. Level up when the alien fleet is destroyed, updating scores and visuals.

Track game stats during alien ship collisions by creating a game stats class. Update ships left when a hit occurs, reset the fleet, and pause briefly.

Develop and display the player's remaining lives, manage a group of ships, and update the scoreboard as ships are hit and levels progress in a Python game.
