Assignment $5$A: Meteor Evader

In this assignment, you will create a game where the player controls a spaceship and must navigate through space to avoid incoming meteors. The goal is to survive as long as possible by dodging meteors coming from all directions. The game will increase in di$$iculty over time, with more meteors appearing. The game ends when the player collides with a meteor.

Requirements:

$$The game window must be $800$ pixels wide by $800$ pixels tall.

$$Player Control:

o The player controls a spaceship using the W$,$ A$,$ S$,$ D keys $($up$,$ left, down, and right respectively$).$

o The spaceship should be represented using a Pygame Rect $($e$.$g$.,$ a $40$x$40$ pixel rectangle$).$

o Ensure that the player cannot move outside the game window boundaries.

$$Meteors should spawn from the edges of the screen $($top$,$ bottom, left, and right$).$

$$A random side is chosen for each meteor$$s spawn location.

$$Based on the side from which a meteor spawns:

o Top: Moves downward. o Bottom: Moves upward. o Left: Moves rightward. o Right: Moves leftward.

$$ Meteor Movement:

o Each meteor should have a horizontal $($dx$)$ and vertical $($dy$)$ speed component to control its movement direction.

o The speed components are determined based on the side from which the meteor spawns so that it moves inward toward the center of the screen.

o The meteors should vary in size and speed $($randomly generate meteor sizes between $20$x$20$ and $60$x$60$ pixels and randomize their speed components$).$

$$New meteors should spawn every $5$ seconds.

$$Gradually increase the spawn rate or speed of the meteors as the player survives

longer.

$$Timer:

o Implement a timer that displays how long the player has survived.

o The timer will start when the game loop begins.

o The timer will stop when the spaceship collides with a meteor $($game ends$).$

o The game will display the final survival time after a collision and reset the game.

$$The longer the player survives, the more meteors should spawn, making the game progressively harder.

$$Use Pygame$$s colliderect$()$ method to detect collisions between the player's spaceship and meteors.

$$If the spaceship collides with any meteor, the game should end.

$$Implement a scoreboard to display the player's longest survival time.

$$The longest survival time should be stored and displayed even after the player loses.

$$When the player$$s spaceship collides with a meteor, play a crash$-$like or destruction$-$like sound.

$$Play a sound e$$ect every time a new meteor spawns to alert the player.

$$Ensure the sound files are loaded using pygame.mixer.Sound$()$ and play the sounds

at the appropriate events during gameplay.

$$Gradually speed up or slow down the meteors over time based on how long the player survives.

$$Make meteors visually distinct $($e$.$g$.,$ di$$erent colors or random shapes$).$

$$Optional: Add background music to play throughout the game

using pygame.mixer.music.

Hints:

$$Use pygame.Rect to represent both the spaceship and meteors for easy collision detection.

$$Randomize the spawning side and speed of each meteor using random.choice$()$ and random.randint$().$

$$Use pygame.time.get$\_$ticks$()$ or pygame.time.Clock$()$ to manage meteor spawn timings and track the player's survival time.

$$Adjust meteor direction and speed using the dx and dy values based on where the meteor spawns.

$$Use pygame.font.Font$()$ to display the timer and score on the screen.

$$To load and play sound e$$ects$,$ use pygame.mixer.Sound$(\text{'}$filename$.$mp$3\text{'}).$play$().$

$$For background music,

use pygame.mixer.music.load$()$ and pygame.mixer.music.play$(-1)$ to loop it continuously.
