Animation mirror

Hello everyone,

I use the 2D engine, to create a beat them all

I have a question about the mirror effect of an animation.

I created a gameObjet (a box) and place it on the stage.
I created an animation for this box. The box falls on the right when the player is on the left and hit it (logic)
However, when my player is on the right and hit this box to the left, it always falls to the right, which of course doesn't make sense.

Several choices obviously exist but if other methods, do not hesitate:

- Either I create another animation with the box falling on the left (I would not like to use this process because too many gameObjects in this same case
- Either I try to play with the methods animationClip.SetCurve, animationcurve and others directly in the script (if I understood correctly). Apparently, this remains the most "complex". I couldn't find a specific example...
- Either I would like to use the "Mirror" checkbox directly on the animation (tried, didn't work, can you help me on this and if this checkbox is good for that?)

Thank you.

I have version 2020.3.14f1 Personal
