I have this method in my game and I'm getting the "Unreachable code" warning from pylint.
def _check_buttons(self, mouse_pos):
"""Check for buttons being clicked and act accordingly."""
buttons = {
self.play_button.rect.collidepoint(mouse_pos):
lambda: (self._reset_game(),
setattr(self, 'show_difficulty', False),
setattr(self, 'show_high_scores', False),
setattr(self, 'show_game_modes', False)),
self.quit_button.rect.collidepoint(mouse_pos):
lambda: (pygame.quit(), sys.exit()),
self.menu_button.rect.collidepoint(mouse_pos):
self.run_menu,
self.high_scores.rect.collidepoint(mouse_pos):

}
for button_clicked, action in buttons.items():
if button_clicked and not self.stats.game_active:
action()
The warning is in the for loop at the end, I thought it was because button_clicked is always True and I tried to swap it to: if not self.stats.game_active and button_clicked, but the warning is still there. Why?
While I tried to simplify my code, I solved the problem by doing this:
def create_button_actions_dict(self):
"""Create a dictionary mapping buttons to their corresponding actions."""
return {
self.play_button: self.handle_play_button,
self.quit_button: self.handle_quit_button,
self.menu_button: self.run_menu,

self.game_modes: self.handle_game_modes_button,
self.endless_button: self.handle_endless_button,
self.easy: self.handle_difficulty_button(0.3),
self.medium: self.handle_difficulty_button(0.5),
self.hard: self.handle_difficulty_button(0.7),
self.difficulty: self.handle_difficulty_toggle
}
