Holding Crossbow Animation

[squib]

Hi,

So basically, I'm trying to make a gun script. I want it so that when a player is holding a certain item (which is a firearm), they will hold it like they would with a crossbow. I've never done something like this before, so I have no idea where to start. But I don't wanna be spoon fed, I wanna be taken through the whole process and learn something from it. There's a few other related questions I have for this, but I believe it'd be more convenient if they're answered one at a time:

- Is it possible to play the holding loaded crossbow animation when a player holds a certain item that isn't a crossbow? If so how? Or would I have to use an actual crossbow item?
- Is it possible to cancel the player punch animation upon left clicking?
- Once the whole holding loaded crossbow thing is figured out, how would I play the reloading animation?

The addons I have are SharpSK, SkBee, SkQuery, and SkStuff.

Please respond soon because I have a limited time to get this done. Thank you.

command /gun:
    trigger:
        set {gun} to a crossbow named "&cAssault Rifle"
        set nbt of {gun} to "{Unbreakable:1b}"
        give {gun} to player

on left click holding a crossbow:
    if player's tool is a crossbow named "&cAssault Rifle":
        cancel event
        play sound "minecraft:item.crossbow.loading_end" at player
        if "Charged" of nbt of player's tool is true:

Something like this no?
