How do you end game when lives finish in game maker?

To end the game when lives finish in GameMaker, you can check the player's lives in the Step event. When the lives reach zero, you can trigger the game-over condition by displaying a "Game Over" screen or transitioning to a different room. Use the game_over variable to manage the state and prevent further gameplay actions. Additionally, you can implement a reset or restart option to allow players to try again.
