using UnityEngine;

public class PlayerFightState : PlayerBaseState
{
public override void EnterState(Player player)
{
player.anim.SetBool(“IsFight”,true);

}
public override void update(Player player)
{
    if (!player.anim.GetCurrentAnimatorStateInfo(0).IsName("Fight"))//getting curr
    {
        player.anim.SetBool("IsFight", false);
        player.SwitchState(player.idleState);
    }
}
public override void OnCollisionEnter(Player player, Collision collision)
{
    
}

}

Its basically Finite State Machine implementation.
Actually i want to play the fight animation when key F is pressed(that is given when the state change from another state so key is not problem), when i press F animation is not playing.
idk why?
