The software development life cycle (SDLC) consists of six basic phases: requirement gathering and analysis, design, implementation, testing, deployment, and maintenance. A roadmap for creating a game includes conceptualization and planning, design of the game mechanics and visuals, coding the actual game functionalities, rigorous testing for bugs and user experience, deploying the game for users, and ongoing maintenance and updates based on user feedback.
For testing, a simple function could be:
def check_player_health(health):
if health <= 0:
return "Game Over"
else:
return "Player is alive"
This routine checks a player's health status and serves as a basic validation case throughout the SDLC phases.
