Hi all, could anyone explain why this code works with “else if” but doesn’t work if it is only “if”. Thanks.

	void Start () {
        restart.onClick.AddListener(restart_game);
        exit.onClick.AddListener(exit_game);
        resume.onClick.AddListener(resume_game);
        mainScreen.onClick.AddListener(main_screen);
        isGameOver = FindObjectOfType<collision_detect>().is_game_over;
        game_paused = false;
        
	}
	
	// Update is called once per frame
	void Update () {

        if(Input.GetKeyDown(KeyCode.Escape))
        {

            if(game_paused == true)
            {
            restart_button.SetActive(false);
            exit_button.SetActive(false);
            gameOver.SetActive(false);
            resume_button.SetActive(false);
            game_paused = false;
            Time.timeScale = 1;
            }

            else if(game_paused == false)
            {
            gameOverText.text = "game paused";
            restart_button.SetActive(true);
            exit_button.SetActive(true);
            gameOver.SetActive(true);
            resume_button.SetActive(true);
            game_paused = true;
            Time.timeScale = 0;
            }

        }

Are you asking why it doesn’t work properly if that else if block was removed? Well, you wouldn’t have anything to change your game_paused from false to true, as it could only go from true to false.

If you’re wanting to have a single block, you could do:

if(Input.GetKeyDown(KeyCode.Escape))
{
    game_paused = !game_paused;
        
    restart_button.SetActive(game_paused);
    exit_button.SetActive(game_paused);
    gameOver.SetActive(game_paused);
    resume_button.SetActive(game_paused);

    Time.timeScale = (game_paused) ? 0 : 1;
}
