Lesson 5: Move the Spaceship

Use the left and right arrow keys to glide your ship across the screen.

Step 1: Add Speed

player_speed = 0

Step 2: Handle Key Presses

# inside your game loop
for event in pygame.event.get():
    if event.type == pygame.KEYDOWN:
        if event.key == pygame.K_LEFT:
            player_speed = -0.5
        if event.key == pygame.K_RIGHT:
            player_speed = 0.5
    if event.type == pygame.KEYUP:
        if event.key in [pygame.K_LEFT, pygame.K_RIGHT]:
            player_speed = 0

Step 3: Move the Player (+ keep on screen)

player_x += player_speed
player_x = max(0, min(player_x, 800 - player_img.get_width()))
