I know it's a mess but the working version of the code is just coding

oh you want to get item attack value? that is easy:

itemType:getAttack()

or

item:getAttribute(ITEM_ATTRIBUTE_ATTACK)

I can't program from objects, I did it for the first time and I still can't hehe... but I found a solution for myself and it was:

local attackAttribute = attacker:getSlotItem(CONST_SLOT_LEFT):getAttack()

--and--

local defenceAttribute = creature:getSlotItem(CONST_SLOT_LEFT):getDefense()

Thanks a lot @Evil Puncker , I knew the commands mate, I found them in the server sources, I didn't know how to use them and unfortunately by trial and error I managed to find a solution, nothing else would work for me and it always returned null or I used the wrong method for the command . If anyone would like to add some info on functions starting with getting and setting elements and modifying those values then feel free to add a post below for me and others looking for a solution or a link to a tutorial. I will thank you have a nice day greetings.
