WeaponData class for common data

[CJCrafter]

The Problem(s)

1. We do not save ItemMeta between method calls, so getting/setting an NBT tag is taking up too many resources. This is because ItemStack#getItemMeta
2. In a lot of our handlers and events, we pass the same 3-5 arguments every time.

data class WeaponData(
    val shooter: LivingEntity,
    val weaponTitle: String,
    val weaponStack: ItemStack,
    val weaponMeta: ItemMeta,
    val slot: EquipmentSlot,
): CastData {

    val mainhand: Boolean
        get() = (slot == EquipmentSlot.HAND)
        
    // other methods for getting NBT tags

    // other methods for CastData for easy mechanics casting
}

Pros

• Cleaner code
• Removes null checks from code since we only do it once
• Performance increase from saving the weaponMeta
• Performance increase from caching all values
• Performance increase from skipping new CastData instantiations

Cons

• Refractoring in:
  • Events API constructors
  • All handlers
  • boiler plate at the start of handlers (weaponData#getWeaponStack)

Notes

• This does not have to be in Kotlin, just wrote in kotlin for example
• If anybody would like to fund to have this coded, let me know :)
