i need help with my sidescroller

hi - i’m making a 3d sidescroller for web, phones, tablets, and i need a tutorial (or maybe a way to copy blueprints, wink?) to make the meu, to make a gun and shoot stuff or a melee sword to kill enemies (i have a halo sword but its useless, it just stays in one place, i dont know how to set it up. i also need a WORKING respawn tutorial, i tried the newton oneand it wont work! anyway, here is what i have so far: v=qUSUfw90BqU

Menu: ://www.youtube/ (strange way how you can do it, but it works :p)
Sword: create a blueprint with the sword in it and then attach it to a socket from your character -> now in the sword bp you can give the damage to the player/enemy (apply damage)
Attack Anim:
Gun (basics): ?v=ojvuTz4KCfE
