Table filling problem

[Nonameman]

Hey!

I have more than 40 pictures in my resource's image folder, and I wanna create them when a client player clicks on a gui button.

I want to show only 1 picture in the same time, from a table, but I dunno how to fill up it first.

(the table would contains the name of the files, without ".png")

How can I do the filling?

Thanks

filling?, once you made the table no need for filling.

You want it random?

If so here how you can get a random element from a table:

local randomElement = theTable[math.random(#theTable)]

On filling I mean that you said, creating the table with the variables. So my problem is the creation of it, how to get the picture names from the folder. Manually, it'd take a long time.

how said JR10, u can use a random:

this can be the img path:

"img/"..theTable[math.random(#theTable)]..".png"

Something like this:

local images = {} 
for i, image in ipairs(getResourceFiles(getThisResource(), ".png")) do 
table.insert(images, image) 
end 
triggerClientEvent("recieveImagesTable", root, images) 
  
  
function getResourceFiles(resource, ext) 
    local filesTable = {} 
    ext = ext or "" 
    local meta = xmlLoadFile(":"..getResourceName(resource).."/meta.xml") 
    if meta then 
        local i = 0 
        while xmlNodeGetChildren(meta, i) ~= false do 
            local node = xmlNodeGetChildren(meta, i) 
            local src = xmlNodeGetAttribute (node, "src") 
            if src then 
                if src:lower():find(ext) then 
                    table.insert(filesTable, src) 
                end 
            end 
            i = i + 1 
        end 
        xmlUnloadFile(meta) 
    end 
    return filesTable 
end

Uhh, yes, thanks a lot!

I have only one questions about this code:

if src:lower():find(ext) then 

What's that? I've never seen ':' in lua, so I do not how is it works.

[JR10]

Well

look at this code:

string.find("blabla", "bla") 
string.lower("BLABLA") 

Which is exactly the same as

local str = "blabla" 
str:find("bla") 
  
local str = "BLABLA" 
str:lower() 

And here strings tutorial: http://lua-users.org/wiki/StringLibraryTutorial

[Nonameman]

So

str:lower():find("xyz") 

has 2 string operation in 1.

Thanks again, and sorry for noobish questions.

[JR10]

Yep, no problem.
