random location!

[Stevenn]

i dont know what i am doing wrong

bad argument @ 'createMarker'

local locationTable = 
    { 
        { -2128, -80, 36 }, 
    } 
    
function getRandomLocation ( ) 
    return unpack ( locations [ math.random ( #locationTable ) ] ) 
end 
  
  
function buttonClick(button) 
    if (button) ~= "left" then return end 
    if (source == acceptJob) then 
    triggerEvent ( "markerLocation3",lp ) 
        end 
end 
addEventHandler("onClientGUIClick", resourceRoot, buttonClick, true) 
     
addEvent ( "markerLocation3", true) 
function markerLocation () 
        markerLocation2 = createMarker ( x, y, z, "cylinder",250,250,250 )  
        blip = createBlipAttachtedTo ( markerLocation2, 53 ) 
        end 
addEventHandler("markerLocation3",root,markerLocation) 
         
acceptJob = guiCreateButton(37,58,94,49,"Accept",false,truckWindow)

Try changing:

  
function getRandomLocation ( ) 
    -- Here you try to unpack from table 'locations' ( That doesnt exist ) 
    return unpack ( locations [ math.random ( #locationTable ) ] ) 
end 
  

to:

  
function getRandomLocation ( ) 
    -- Instead unpack from 'locationTable' 
    return unpack ( locationTable [ math.random ( #locationTable ) ] ) 
end

still bad argument at createMarker..

[drk]

local tLocations = 
{ 
    { -2128, -80, 36 }; 
} 
  
addEvent ( 'onClickCreateMarker', true ); 
  
acceptJob = guiCreateButton ( 37, 58, 94, 49, 'Accept', false, truckWindow ); 
  
function getRandomLocation ( ) 
    return unpack ( tLocations [ math.random ( #tLocations ) ] ); 
end 
  
addEventHandler ( 'onClientGUIClick', root, 
    function ( uType ) 
        if ( uType ~= 'left' ) then 
            return; 
        end 
         
        if ( source == acceptJob ) then 
            triggerEvent ( 'onClickCreateMarker', localPlayer ); 
        end 
    end 
) 
  
addEventHandler ( 'onClickCreateMarker', root, 
    function ( ) 
        local nX, nY, nZ     = getRandomLocation ( ); 
        local cMarker        = createMarker ( nX, nY, nZ, 'cylinder', 250, 250, 250 ); 
        local blip           = createBlipAttachedTo ( cMarker, 53 ); 
    end 
)

you never get any values for x,y,z:

local locationTable = { 
    { -2128, -80, 36 }, 
} 
    
function getRandomLocation ( ) 
    return unpack ( locationTable [ math.random ( #locationTable ) ] ) 
end 
  
function buttonClick(button) 
    if (source == acceptJob) and (button == "left") then 
        triggerEvent ( "markerLocation3",lp ) 
    end 
end 
addEventHandler("onClientGUIClick", resourceRoot, buttonClick, true) 
    
addEvent ( "markerLocation3", true) 
function markerLocation () 
    local x,y,z = getRandomLocation() 
    markerLocation2 = createMarker ( x, y, z, "cylinder",250,250,250 ) 
    blip = createBlipAttachtedTo ( markerLocation2, 53 ) 
end 
addEventHandler("markerLocation3",root,markerLocation) 
        
acceptJob = guiCreateButton(37,58,94,49,"Accept",false,truckWindow)

ty it works draken, but how can I do this ?

addEventHandler ( "onClientMarkerHit", cMarker , 
    function  ( ) 
        if getElementModel(getPedOccupiedVehicle(lp)) == 437 then 
            triggerServerEvent ( "busStop", lp ) 
        end 
    end 
) 

bad argument @ 'addEventHandler' [Expected element at argument 2, got nil]

cMarker is not global. You must remove "local" before cMarker in the code to use it in other functions.

doesn't work...

First, why you need "theVehicle" parameter in 'onClickCreateMarker' event? Also, what is "lp".

because i was trying something but i remove it, and lp = getLocalPlayer()

[Stevenn]

anyone?

[drk]

What doesn't work?

[Stevenn]

Well, when I hit the "cMarker" I want to trigger the server event, but like I said: Expected element at argument 2, got nil

[drk]

Use:

addEventHandler ( 'onClientMarkerHit', root, 
    function ( uPlayer ) 
        if ( source == cMarker ) then 
            triggerServerEvent ( 'truckStop', uPlayer ); 
        end 
    end 
) 

[Aibo]

Use:

addEventHandler ( 'onClientMarkerHit', root, 
    function ( uPlayer ) 
        if ( source == cMarker ) then 
            triggerServerEvent ( 'truckStop', uPlayer ); 
        end 
    end 
) 

this is a single client code without any checks for element that hit the marker.

so when 1 player hits the marker, the same event will be sent by multiple clients.

it should only trigger if hitElement == localPlayer.

[Stevenn]

if ( source == cMarker and hitElement == localPlayer ) then 

?

[Aibo]

hit element here is uPlayer.

tbh i dont get why, fine with confusing prefixes like "uSomething" and unconventional semicolons.

but hit element not necessarily is a player. so that name is misleading.

and you should learn about variables and how do they work. this is programming basics.
