This event is dispatched before the main Game Step starts. By this point in the game cycle none of the Scene updates have yet happened. Hook into it from plugins or systems that need to update before the Scene Manager does.
The current time. Either a High Resolution Timer value if it comes from Request Animation Frame, or Date.now if using SetTimeout.
The delta time in ms since the last frame. This is a smoothed and capped value based on the FPS rate.
