The function will work properly?

[rE5vK8bu]

  
--table 
weaponInfo = { 
    {name = "M4",id = 31,slot = 5,ammo = "M4 Mag",mag_size = 30,damage = 5000,model = 356,new_model = 1241,is_sniper = false}, 
    {name = "Sniper",id = 34,slot = 6,ammo = "Sniper Mag",mag_size = 10,damage = 5000,model = 358,new_model = 1252,is_sniper = 1252}, 
} 
  
--function 
function getWeaponInfo(item) 
    for _,v in ipairs(weaponInfo)do 
        if item == v.name then 
            return v.name,v.id,v.slot,v.ammo,v.mag_size,v.damage,v.model,v.new_model,v.is_sniper 
        end 
    end 
end 
  

The function will work if I use the script that way in a function? in disarray?

local name,slot,mag_size,ammo = getWeaponInfo(currentweapon)

If you won't test it no, but visually its fine.

What is currentweapon?

If it's the name, why are you returning the name?

You use return v.name (1), v.id (2), v.slot (3), v.ammo (4), v.mag_size (5) ...

But you use:

local name (1), slot (3), mag_size (5), ammo (4) 

The order is totally wrong.

I do not want to create it:

local name,id,slot,ammo,mag_size,damage,model,new_model,is_sniper = getWeaponInfo(getElementData(source,"current_weapon_1")) 

I want to create a main function. I do not want to create more functions from the table

Who said anything about create?!

This way its correct, because the order is right.
