TFS 1.X+ Accuracy of a dystasium attack with a weapon

[Michcol94]

Hello. I created a ranged "bullet" weapon without ammunition, everything is beautiful, but how to set the accuracy of the weapon so that it is always 100% on target. Can you do it in Lua ? Do I need to change the source code? Please help I strongly care that the accuracy was 100%.
action/ball.lua

function onUse(player, item, fromPosition, target, toPosition, isHotkey)
    if target and target:isCreature() then
        local damage = math.random(10,50) -- możesz dostosować minimalne i maksymalne obrażenia
        target:addHealth(-damage)
       
        return true
    end
    return false
end

items.xml

<item id="12662" article="a" name="ball" plural="balls">
    <attribute key="weight" value="500" />
    <attribute key="slotType" value="two-handed" />
    <attribute key="weaponType" value="distance" />
    <attribute key="attack" value="50" />
    <attribute key="range" value="7" />
    <attribute key="shoottype" value="ball" />
    </item>
