wait(0.3)

Unity Engine
1

how would i make a wait command? If it is possible, without Coroutine? Just something like

//do the first thing
wait (0.3f);
//do the second thing

I am using c#. thank you

It is possible without a coroutine, but it’s not very fun.

enum State {
  First,
  Wait,
  Second,
  Done
}

float startTime;
public float waitDuration = 1f;

State state = State.First;

void Update() {
  if(state == State.First) {
    // First thing
    state = State.Wait;
    startTime = Time.time;
    return;
  }

  if(state == State.Wait) {
    if(Time.time - startTime > waitDuration) {
      state = State.Second;
    } else {
      return;
    }
  }

  if(state == State.Second) {
    // Do second thing
    state = State.Done;
  }
}

Or you could just use a coroutine and do this.

void Start() {
  StartCoroutine("DoThings");
}

IEnumerator DoThings() {
  DoFirstThing();
  yield return new WaitForSeconds(1f);
  DoSecondThing();
}

Thank you, i’ll definitely use a coroutine XD
EDIT: What exactly is a coroutine? Is it the timer, or the thing you need to start the timer?

Actually, I think Start can be a coroutine itself. It’s the same exact thing, but a bit more succinct. It’s also neat that most Unity callbacks can be used as coroutines.

IEnumerator Start() {
  DoFirstThing();
  yield return new WaitForSeconds(1f);
  DoSecondThing();
}

It’s pretty simple, but coroutines are more elegant - yet they can yield significant amounts of garbage.

        const float TimeToWait = 1f;
        private float _actualTime;

        public void Update()
        {
            _actualTime += Time.deltaTime;
            if (_actualTime >= TimeToWait)
            {
                Debug.Log("We waited.");
                _actualTime = 0; // reset this so it keeps going
            }
        }

You could use Invoke :

public void DoThat()
{
/Idk
Invoke (StopThat,5) // 5 Is the seconds before the invoke.
}
public void StopThat()
{
//idk
}

Hope i helped!
