sword projectile support better combat API

i need help on how to make my sword shoot projectiles on swing WITH better combat api. i can make my sword swing like a claymore, but when it does it doesnt shoot anything. i want the sword to shoot projectiles when swinging, i already tried hooking it to the "when entity swings item" but nothing works. i assume better combat overwrites the swinging animation for their attack animation but i want my sword to shoot when doing the swinging animation, like in marium's soulslike weaponry the moon sword shoots projectiles even despite having better combat. if anyone knows how to do this in mcreaor please help me, or any tips.
