How to flip hitboxes if my 2D Sprite is Flipped in AnimationsEditor ? [Unity2D]

Hello Unity Community ! First of all, note that I looked around the net to find some solutions to my problem before posting here, w$$anonymous$$ch wasn't a success xD. I will try to be as clear as possible. I'm working on a 2D Platformer since a w$$anonymous$$le. In my code, atm, when I click with my mouse, my 2D Sprite character will attack. And today, I decided to create the sword $$anonymous$$tboxes.

I basically created 3 c$$anonymous$$lds GameObjects under my character's GameObject called SwordHitBox1 / 2 / 3, w$$anonymous$$ch have polygonColliders2D set as Triggers, each edited in coordination to their sword attack animation frames (I switch those $$anonymous$$tboxes GO's to Active / Unactive when desired in the animation editor). Associated with an OnTriggerEnter2D in my character script, everyt$$anonymous$$ng works pretty good !

BUT, these $$anonymous$$tboxes work when my character is facing right. I mean, they are designed for my character when he's facing right. Designing those for when my character is facing left is not the problem, the problem is that I don't understand how I'm supposed to tell the animation editor WHEN my character sprite is flipped or not. If I could implement an (if character.flipX() == true) in the animation editor, THEN I could design the $$anonymous$$tboxes for my character when he's facing the left.

Cause yeah, note that I used the SpriteRenderer.flipX() method in my character script to flip my character sprite whenever the player decides to walk to the right or the left.

I hope that it makes sense, and I'm really looking forward to any source of help. Thanks for reading !
