guiGridListSetData. Need Help.

[PotatoHead]

So I am working on a GridList and I am trying to set the date. What I want to know is if there is a way to have multiple data points. I wish to know so I can find out how to place the data if you need the script posted please let me now. Thanks.

Use a table in guiGridListSetItemData.

Examp:

guiGridListSetItemData ( gridlist, 2, 1, { "data1", 200, getPlayerName ( localPlayer ) } ) 
  
for i, v in ipairs ( guiGridListGetItemData ( gridlist, 2, 1 ) ) do 
    outputChatBox ( tostring ( v ) ) 
end

Hey. Thanks it worked. Now I am wondering if there is a way to transfer it to a server side script. I want to know because I am working with spawn cords. I wish to use the X Y Z values in a spawnPlayer() function.

[Castillo]

You can send them using triggerServerEvent.

[PotatoHead]

Okay. But will it send automatically in x, y, z data? If you need the piece of code let me know.

[Castillo]

You can unpack the table stored on the grid list.

unpack

Thnaks Solidsnake. One problem where would I put that whne retriving the guiGridListGetData? The code starts by taking the cords from an XML file then sets each x, y, and z cord on those values then sets the gridlist data. Now how could I retrive them in that order with the unpack function?

[Castillo]

Get the selected item with guiGridListGetSelectedItem, then use guiGridListGetItemData.

Hello once again Solidsnake. I hope this will be my final request. Right now I just get the output of nil.

No need for loops.

function makeList() 
    local file = xmlLoadFile("spawnpoints.xml") 
    if file then 
        for _, spawns in ipairs (xmlNodeGetChildren(file)) do 
            local row = guiGridListAddRow(glistMainList) 
            local name = xmlNodeGetAttribute(spawns, "name") 
            local x = xmlNodeGetAttribute(spawns, "x") 
            local y = xmlNodeGetAttribute(spawns, "y") 
            local z = xmlNodeGetAttribute(spawns, "z") 
            guiGridListSetItemText(glistMainList, row, 1, name, false, false) 
            guiGridListSetItemData(glistMainList, row, 1, {x, y, z}) 
        end 
        xmlUnloadFile(file) 
    end 
end 
  
function spawnHandler(button, state) 
    if button == "left" and state == "up" then 
        local row, col = guiGridListGetSelectedItem(glistMainList) 
        local data = guiGridListGetItemData(glistMainList, row, col) 
        if row and col and row ~= -1 and col ~=-1 then 
            local x, y, z = unpack ( data ) 
            outputChatBox(x) 
            outputChatBox(y) 
            outputChatBox(z) 
        end

Works great. Thanks Solidsnake. You rock man!

You're welcome.

Last issue. Now I am getting a stack overflow error. These are my scripts in full.

There's the problem, you named the function the same as the native one you are using, so, is executing over and over again.

Rename it, like this:

function spawnPlayer_(x, y, z, player) 
    spawnPlayer(player, x, y, z) 
end 
addEvent("spawnPlayer", true) 
addEventHandler("spawnPlayer", getRootElement(), spawnPlayer_)
