The six basic phases of the software development life cycle (SDLC) are requirements gathering and analysis, design, implementation, testing, deployment, and maintenance. A roadmap for creating a game includes defining game mechanics and story, designing levels and characters, coding game features, testing gameplay for bugs and performance, launching the game, and providing ongoing updates and improvements.
For a simple test case, you could use the following code snippet to check if the player's score meets a winning condition:
score = 50 # Example score
if score >= 100:
print("You win!")
else:
print("Keep trying!")
This can serve as a basic validation point during the testing phase of the SDLC.
