Increment in every millisecond realtime?

Hi, im try to make tycoon game, i know how to increment for every second but how about +1 in every millisecond in real time?

I don’t know what do you mean by “real time”, since your updates depend on your framerate, and I really really doubt that happens every millisecond.

That said, you can easily get the amount of miliseconds elapsed between frames using Time.deltatime.

    public class MillisecondCounter : MonoBehaviour
    {
        float elapsed;
        int milliseconds { get { return Mathf.FloorToInt(elapsed * 1000); } }

        void Start()
        {
            elapsed = 0;
        }

        void Update()
        {
            elapsed += Time.deltaTime;
        }
    }

You can use that milliseconds value to increment whatever you need.
