Apply rigid body to your character and add this code for the object which is going to destroy and make effects for character.

//Apply a Player Transform to choose the character transform.

if (Vector3.Distance(player.transform.position, transform.position) < 15) { // Make player die HealthController hc = player.GetComponent(); hc.health = 0;

        // Make player fly into the air
        CharacterController cc = player.GetComponent<CharacterController>();
        cc.Move(((player.transform.position - transform.position).normalized * 15 + Vector3.up * 5) * Time.deltaTime);
    }
