How to play character turning animation when the camera rotates s certain degree like in fornite

Hi guys, i’m trying to make a third person controller like in fornite, it’s pretty much done but i still can’t figure out how to play character’s underbody turning animation

Get the angle between the camera and the players forward position

void Update()
{
	var cam = Camera.Main.transform;

    Vector3 targetDir = new Vector3 (0, cam.forward.y, 0);
    float angle = Vector3.Angle(targetDir, transform.forward);

    if (angle < 10.0f)
		DoTheAnimationSequence();
}
