In this Unity UI Prototyping Game (Session 51), we complete a fully playable loop by adding a Game Over screen and a Restart button that resets everything and starts the game again.
Right now, the player can keep scoring even after losing — so in this session we fix that properly:
✅ Show Game Over UI only when the player actually loses
✅ Stop spawning when the game ends
✅ Disable click/explosion events after game over
✅ Add a Restart button using a UI Button OnClick event listener
✅ Reload the active scene using SceneManager for a clean restart
✅ What you will learn in this session
How UI Buttons act as event listeners
Creating a Game Over Panel using Unity UI + TextMeshPro
Making UI appear only when needed (SetActive(false/true))
Adding GameOver() logic inside GameManager
Triggering Game Over only for Good targets using a boolean flag (isGood)
Stopping coroutines/spawning using while(!isGameOver)
Blocking input/gameplay after Game Over
Restarting the game with:
using UnityEngine.SceneManagement;
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
Wiring the Restart button to a public method from the Inspector
