Is there a way to make a hitbox ignore another one?-CodePudding

I was creating a multiplayer first-person medieval fighting game based on Skyrim and For Honor combat, with 3 different stances. In it, you can attack from 3 stances, and if the opponent is not holding the same stance, he takes the attack, otherwise he parries and the attacker takes a quick stun. The problem starts when the Sword's Hitbox hits the player's own hitbox, causing unwanted results.

That's why I want to know if there is a way for making the player's sword ignore the collision with the player itself, so that he can't attack himself.

I also tried to put the method: Physics.IgnoreCollision(collider, selfCollider); Inside the OnTriggerEnter() function, Startup() and Update(), and no solution worked.

    private void OnTriggerEnter(Collider other)
{
    if (other.gameObject.tag == "Enemy" || other.gameObject.tag == "Player")
    {
        //instant enemy combat
        CombatManager enemy = other.gameObject.GetComponentInChildren<CombatManager>();
        Debug.Log(enemy.currentStance);
        //If enemy stance is not the same of the attacker
        if(enemy.currentStance != this.currentStance)
        {
            //enemy is damaged
            //Get enemy LifeManager and subtract its health
            enemy.GetComponentInParent<LifeManager>().currentHealth -= swordDamage;
        }
        else
        {
            anim.SetTrigger("Parried");
        }
    }

Try:

if(other.transform.root != transform.root)
{
    // NOT self collision
}

This basically checks if both objects belong to the same hierarchy. In other words if they have the same top-most GameObject or root.

Obviously I made some presumptions as to how your players avatars are rigged. Perhaps you will need to tweak this solution to suit your hierarchy.

You can decide which collision layers collide with others. Here is the link to the documentation.
