Best Run

Part of the Building Real Games section of Coddy's Unity journey. Lesson 32 of 56.

Challenge

Medium

Last step: remember the best run. Keep everything from the earlier lessons. The canvas has a BestText in the top right, and the panel a hidden NewBestText (New best!); the scene puts them in two new fields of GameManager, public TMP_Text bestText; and public GameObject newBestText;. Save the best under the key BestRun, in whole meters:

In Start(), load the best (0 for a new player) and show it as Best: 57 m.
In GameOver(), when the run's whole meters, Mathf.FloorToInt(distance), beat the best, save the new best, show it, and show newBestText. A shorter run changes nothing.

The best stays through Run again and through quitting the game. Press Play, set a best and try to beat it, then Check.

Try it yourself

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
using TMPro;

public enum GameState { Playing, GameOver }

public class GameManager : MonoBehaviour
{
    public static GameManager Instance;

    public float speed = 10f;
    public float speedUp = 0.5f;
    public float maxSpeed = 20f;
    public TMP_Text distanceText;
    public GameObject gameOverPanel;
    public Button restartButton;
    public GameState state = GameState.Playing;
    private float distance;

    void Awake()
    {
        Instance = this;
    }

    void Start()
    {
        restartButton.onClick.AddListener(Restart);
    }

    void Update()
    {
        if (state != GameState.Playing) return;

        speed = Mathf.Min(speed + speedUp * Time.deltaTime, maxSpeed);
        distance += speed * Time.deltaTime;
        distanceText.text = "Distance: " + Mathf.FloorToInt(distance) + " m";
    }

    public void GameOver()
    {
        state = GameState.GameOver;
        speed = 0f;
        gameOverPanel.SetActive(true);
    }

    void Restart()
    {
        SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
    }
}
