Most entity script contexts include the script table, which provides bindings for getting and setting the script's update rate. Update deltas are specified in numbers of frames, so a script with an update delta of 1 would run every frame, or a script with an update delta of 60 would run once per second. An update delta of 0 means that the script's periodic update will never be called, but it can still perform actions through script calls, messaging, or event hooks.
Sets the script's update delta.
Returns the duration in seconds between periodic updates to the script.
