Description

This class represents the midst unit (a.k.a unit of time) in animation. Currently, it provides two states: milliseconds and 60FPS (frames per second). When you create an animation key, you'll need to set the value according to the incoming time. This class also provides different unit conversions such as GetFrameIndex, IndexedFrameTime, and GetFrameTime to ensure that the time retrieved is aligned with animation frames.

Operators

==

The "equal to" operator. Check if two time objects are equal.

Returns

True if the values of the two time objects are equal, else False.

See Also: != 

 1 # Equivalence operator

 3 time2 = RLPy.RTime(3000)
 4 print(time1 == time2)
 5 
 6 # Compare current time
 7 time = RLPy.RGlobal.GetTime()
 8 
 9 if time == RLPy.RGlobal.SetTime(RLPy.RTime(1000)):
10    print("equal")
11 elif time > RLPy.RGlobal.SetTime(RLPy.RTime(1000)):
12    print("greater")
13 elif time < RLPy.RGlobal.SetTime(RLPy.RTime(1000)):

True if the values of the two time objects are not equal, otherwise return False.
