Flip vertical

Hi,
One more help. I have a 2D texture of a character applied to a gameobject. the character is facing left. I want to make it face right. I tried using transform.up/forward/right with different values, but nothing’s happening.
can some tell me of how to flip this game object vertically so the object faces the opposite direction instead.

Thanks.

Maybe try

transform.localScale = Vector3(-1,0,0); // make it face opposite x direction
