You can think
of tweening like the computer looking at your two frames, and making one in-between.
Modes are math equations, that tell how to tween . Making it faster, slower, or even stepped.
Now, there’s different modes:
- None (Linear, moves like a robot.)
- In (Quadratic-In, slower in the start, gets faster in the end.)
- Out (Quadratic-Out, slower in the end, faster in the start
- In-Out (Both Out and In.)
I grabbed this from a earlier post.
