Gets the current time on the timeline. That's right!
Rounding down to seconds
As you probably have noticed, the result of "time" is a float, which means it shows the fractional part of the number.
If we want to round our number to only display the current second, like a clock handle, we can do it like so:
Rotate across time
Apply this to a Rotation property and hit preview.
Every one second the rotation will finish a 360-degree lap! That's so cool!
To make it easier to manipulate, we can do something like this:
Now we can easily change "LapDuration" to decide how long we want our Rotation property to complete one lap.
Rotate faster, then faster and faster and faster...
Try applying this to a Rotation property:
Press play. At first, your layer will rotate very very slow, but keep going! It will accelerate and start rotating faster and faster until it's almost too fast for your eye to register to motion properly.
What a cool simple trick right? We are literally multiplying the current time by itself 4 times. By the 2 seconds mark the result is 16 degrees, which is not that impressive. But this increases exponentially, and by the time the timeline hits 10 seconds, we are already at 10,000 degrees! Holy cow.
The exact same expression can also be written down this way:
Math.pow stands for power. We ask our friend, Math.pow() to check for us the result of the current time to the power of 4, which is the same as multiplying time by itself 4 times. Neat!
