Animator recording system is an obscure feature that you find when playing with the Mecanim System.
The idea is to create something like a replay. Record and Playback. Simple, easy and... well, not that easy.
How to use:
Start Record, Stop Record, Start Playback and... nothing work because you really need to manage the playback timeline your own. For that, I`ve created a small piece of code that you can download here.
The idea is:
- Play using Time.deltatime as parameter.
- Pause not updating it.
- Stop Playback when leave the Replay mode.
- Lerp normalized values between start record time and stop record time to create a Timeline.
Animator Record System implements a Cyclic Buffer and can record up to 1000 frames.
Issues:
IK is not recorded
Root position is not recorded
You can see how it works below.
