Managing time and frame rate

It’s important to understand how Unity handles time to ensure your gameplay remains stable. Updates occur at regular time intervals to capture changes to character positions, health status, scores, and so on. If your code makes changes in the wrong update loop or doesn’t allow for variations in time, effects like movement might be too fast, too slow, or jumpy instead of smooth.

The Time class contains properties through which you can get and in some cases set various time-related measurements and settings. Refer to Time in the Scripting API reference for a complete list of the properties and their meanings.
