If you mean, why the slash effect doesn’t look synced up on the attacks, that has to do with how your animation is set up.

I presume the transition to your slash animation doesn’t have exit time nor transition duration? This would allow the animation to play immediately after being triggered,

As for the code, in TripleSlas(), you can see that there is code that dictates how long the boss needs to wait in between attacks. You can adjust the float value to a more suitable pace. Finally, the slasheffect. This has to do with the animation of the slash itself. You can set the animation to play faster or slower by the space in between their keyframes in the animation.

For your Boss not dealing damage on collision, this is intentional as there isn’t a code to allow the Boss to do that. You can simply grab the code from the Crawler, Charger or Bat enemy’s attack method to add it onto the boss.

Thks for the collision damage, it works now, but for the slash animation still doesn’t have a fine solution

I would like to ask that for the bounce attack or any other attack, how do I fix this situation, and other situation is when the boss is casting the skills, how to let player attack wouldn’t stop them for casting

Because in hollow knight, the boss is bounce attack towards the player but only hit the ground, it will not towards the player and hit the wall and stuck

I try to use the comparetag(“Wall”) and set the wall to “Wall”

protected override void OnCollisionStay2D(Collision2D _other)
{
    if (_other.gameObject.CompareTag("Player") && !PlayerController.Instance.pState.invincible && health > 0)
    {
        Attack();
        if (PlayerController.Instance.pState.alive)
        {
            PlayerController.Instance.HitStopTime(0, 5, 0.5f);
        }
    }
    
    if (_other.gameObject.CompareTag("Wall"))
    {
        ResetAllAttacks();
    }
}
