I'm trying to make a countdown timer in Unity, and I've been able to make the timer count down from 10. However, I can't stop it at 0. I've tried putting it in a while loop but it didn't help, it actually made the timer start at 0.
float counter = 10.0f; public TextMesh countdown; void Start () { countdown = gameObject.GetComponent<TextMesh>(); } void Update () { counter -= Time.deltaTime; countdown.text = "Time Left:" + Mathf.Round(timeLeft); if (counter <= 0) { Debug.Log("Hello"); } } Because the update is called constantly, you're always running through this;
counter -= Time.deltaTime; countdown.text = "Time Left:" + Mathf.Round(timeLeft); and never really stopping.
In order to stop, you could try something like a flag- something to tell your loop when to stop the countdown. Though because of the simplicity of your program, you could try this, which doesn't use a flag but rather outputs the time left based on your current condition:
float counter = 10.0f; public TextMesh countdown; void Start () { countdown = gameObject.GetComponent<TextMesh>(); } void Update () { if(counter > 0) { counter -= Time.deltaTime; countdown.text = "Time Left:" + Mathf.Round(timeLeft); } else { Debug.Log("The counter has stopped."); } } Try with
void Update () { if (counter > 0) { counter -= Time.deltaTime; countdown.text = "Time Left:" + Mathf.Round(timeLeft); } else { Debug.Log("Hello"); } Note that this will print "Hello" in the console many time per seconds as soon as the counter reaches 0. This is what your code was doing, I don't know if it was on purpose.
