could you explain it better?
thank you

could you explain it better?
thank you

Yea

I want to check the damage value of the two items.
If the damage of the item you'll use is greater than the hit item. My english it's bad =\ Srry

Example..

ah, I see. potion is a table, so it's accessed by using potion[1111].damage as an example. you're trying to call potion as an attribute of item or itemEx which are not available attributes on those objects.

if itemEx.potion[getItemById(potion.damage)] > item.potion[getItemById(potion.damage)] then

this should be more like

if potion[getItemById(itemEx)].damage > potion[getItemById(item)].damage then

since you're accessing the table by item id, you'd have to set the table values to the ids of the potions like this (strong health and strong mana potions)

local potion = {
[7588] = {
damage = 850,
def = 450
},
[7589] = {
damage = 600,
def = 500
}
}

but I'm not sure I understand what you're trying to achieve. Are you using a potion on another potion?
For further assistance please explain better what you're trying to achieve and provide information like what server distro you're using (if TFS, is it 0.2? 0.3? 0.4? 1.x?

adding up to RazorBlade question:

function onUse(cid, item, fromPosition, itemEx, toPosition)

item = its the item you use (right mouse click)
itemEx = its the item you use at (use with crosshair, for example)

 

[Codex NG]

local potion = {
    [1111] = {damage = 600}
    [2222] = {damage = 850} 
}
-- returns 850 -- if item is 1111 & itemEx is 2222
math.max(potion[item.itemid].damage, potion[itemEx.itemid].damage)

I understand what the function is for
Just trying to figure out what you're trying to achieve

Yes, using a potion on another potion.
I tested it, and it looks like it worked. Thanks man!!!!!
