Code Example (Python / Pygame)

Fragment of the "Purple Sky" game logic — handling ship movement and physics:

            
        class Ship(pygame.sprite.Sprite):
            def __init__(self):
                super().__init__()
                self.pos = pygame.math.Vector2(SCREEN_WIDTH // 2, SCREEN_HEIGHT // 2)
                self.vel = pygame.math.Vector2(0, 0)
                self.angle = 0
                self.thrust_power = 0.25
                self.friction = 0.97

            def apply_thrust(self):
                # Calculating acceleration based on rotation angle
                rad = math.radians(self.angle)
                acc = pygame.math.Vector2(math.cos(rad), -math.sin(rad)) * self.thrust_power
                self.vel += acc

            def update(self):
                self.pos += self.vel
                self.vel *= self.friction  # Applying space friction
                # ... logic for screen wrapping and rotation
