Lua how check isladder?

[beenii]

i want:

if getItemAttribute(itemEx.uid,'floorchange')== "north" then
doSendMagicEffect(toPosition,2)
doPlayerSendCancel(cid,"Sorry, not possible.")
return true
end

or:
if getItemAttribute(itemEx.uid,'floorchange')== true then
doSendMagicEffect(toPosition,2)
doPlayerSendCancel(cid,"Sorry, not possible.")
return true
end

but dont work :/

no error on console

Because north is a direction in the -y, but a ladder or staircase works in the + or - z

Why not print(getItemAttribute(itemEx.uid,'floorchange')) to see what value it returns?

You'll see the output in the server console.

 

[beenii]

is value null.

want check this:
<attribute key="floorchange" />

no way to read from items.xml ?

 

[beenii]

bump

getItemAttribute doesn't exist in tfs 1.0 so i can't even check it for you

 

[beenii]

i try, only now, no work :/
attribute key

function getItemIsLadder(itemId)

local file = io.open("data/items/items.xml", "r")

for info in string.gmatch(file:read("*a"), "<items(.-)</items>") do
if info:match("item id=\"(.-)\"") == itemId then
local attribute key = info:match("attribute key=(.-)")
return tostring(attribute key)
end
end

file:close()
return nil
end

Wrong, item attributes are now supported in tfs 1.x, maybe not that exact function, but it could be easily written in lua for compat or global and made into a function, at any rate, the attribute key floorchange is not supported...

 

[beenii]

thanks for your help friend to have someone help me finish the function

 

[Evan]

Item attributes have always been supported, even in 0.2.
The only thing that isn't supported is custom attributes, which you can still get around in 1.X by using the TEXT attribute.

 

[beenii]

i'm using tfs 0.4

"maybe not that exact function"
Didn't I just say that the function doesn't exist?
Meaning I can't test it, whether there is another way to get an items attributes is irrelevant and saying "Wrong" or "it could be easily written" without actually giving an example makes you sound like a conceited arrogant a-hole.

Have you tried with getItemInfo?

getItemInfo(itemId).floorChange

 

[beenii]

yes i try and no work bro.

need this function: how repair?

function getItemIsLadder(itemId)

local file = io.open("data/items/items.xml", "r")

for info in string.gmatch(file:read("*a"), "<items(.-)</items>") do
if info:match("item id=\"(.-)\"") == itemId then
local attribute key = info:match("attribute key=(.-)")
return tostring(attribute key)
end
end

file:close()
return nil
end

No you are wrong, simply because we do not know if someone has written that function or not is irrelevant, by saying that function doesn't exist means you are mistaken, because before I even posted I could have sat there, and taken the time to write it myself and then have that function in less than two minutes. I wasn't trying to be an asshole, I was merely trying to inform anyone who thinks that server is still missing that functionality knows that it is now supported (since I know that was a major thing that kept people from wanting to switch).

@topic, did you try printing the value returned on a ladder when using the function that ninja posted? If so, I'm interested in what it returned?

 

[Ninja]

It returns an array of floor changes.

local function getItemIsLadder(itemId)
    local floor = getItemInfo(itemId).floorChange
    for i = 1, #floor do
        if floor[i] then
            return true
        end
    end
    return false
end

But you didn't..which proves my point.

local function getItemIsLadder(itemId)
    local floor = getItemInfo(itemId).floorChange
    for i = 1, #floor do
        if floor[i] then
            return true
        end
    end
    return false
end

great joob work perfect bro.
