Solidsnake, it don't works.

I tried it here several ways and I can't get it to work if I remove 'for ... in ..... do' and add a text like 'WHAT THE FUCK' in the row it work.

Ah, I understand now, you're using 'ipairs' instead of 'pairs', you can't use 'ipairs' in that kind of table.

local marker = createMarker (1605.600, -1625.300, 12.5, "cylinder", 2, 25, 50, 255, 255 ) 
local cars = { 
    [596] = 'Police LS', 
    [597] = 'Police SF', 
    [598] = 'Police LV', 
    [599] = 'Police Ranger' 
} 
  
window = guiCreateWindow(561,187,260,388,"Spawn Vehicle",false) 
guiWindowSetSizable(window,false) 
spawnButton = guiCreateButton(26,317,96,37,"Spawn",false,window) 
closeButton = guiCreateButton(142,318,96,37,"Close",false,window) 
carGrid = guiCreateGridList(23,34,210,249,false,window) 
guiGridListSetSelectionMode(carGrid,0) 
column = guiGridListAddColumn(carGrid,"Vehicle name",0.85) 
for id,vehName in pairs(cars) do 
    local row = guiGridListAddRow ( carGrid ) 
    guiGridListSetItemText ( carGrid, row, column, tostring(vehName), false, false ) 
    guiGridListSetItemData ( carGrid, row, column, tonumber(id), false, false ) 
end 
  
function showWindow() 
    local playerTeam = getPlayerTeam (localPlayer) 
    local teamName = getTeamName ( playerTeam ) 
    if (teamName == "Police") then 
        guiSetVisible( window, true ) 
        showCursor(true) 
    end 
end 
addEventHandler ("onClientMarkerHit", marker, showWindow) 
  
function spawn() 
    local row,col = guiGridListGetSelectedItem(carGrid) 
    if (row and col and row ~= -1 and col ~= -1) then 
        local model = guiGridListGetItemData(carGrid, row, 1) 
        triggerServerEvent('onGUIClick',localPlayer,tonumber(model)) 
    end 
end 
addEventHandler('onClientGUIClick',spawnButton, spawn, false) 
    
function setVisible() 
    guiSetVisible(window,false) 
    showCursor(false) 
end 
addEvent('setGUIVisible',true) 
 addEventHandler('setGUIVisible',root,setVisible) 
  
function closeWindow() 
    guiSetVisible(window,false) 
    showCursor(false) 
end 
addEventHandler ("onClientGUIClick", closeButton, closeWindow, false)

oh thanks solidsnake, it works now.

a little question, whats the different between "ipairs" and "pairs" ?

[Castillo]

http://lua-users.org/wiki/TablesTutorial

ipairs works with indexed tables as far as I know, and pairs works with every kind of table (I may be wrong too).

[Sparrow]

oops, I forget that lol.

what I must add to script to set the player can spawn only 1 vehicle?

thanks again...

pairs is for non-indexed tables.

I tried with pairs too but it don't worked.

[Sparrow]

it works with "pairs"

[drk]

Really? Solidsnake has said..

[Kenix]

pairs:

t = { 
  [1] = 1; 
  ['two'] = 2; 
} 
  
for i,v in pairs( t ) do 
   print( i,v )  
   --[[ 
   1    1 
   two  2 
  ]] 
end 

ipairs:

t = { 
  [1] = 1; 
  ['two'] = 2; 
} 
  
for i,v in ipairs( t ) do 
   print( i,v )  
   --[[ 
   1    1 
  ]] 
end 

[Sparrow]

thanks kevin for this information

[Kenix]

No problem

Remember ipairs work only with number indexes and number indexes should be order.

( 1,2,3,.. ) not (1,3,5,.. )

pairs work with all indexes.

[Sparrow]

yes, thank you again

[Kenix]

No problem
