couple of questions

[kuwalda]

Hey, I have some questions that I could not find answers to, so I thought you could help:

addEventHandler('onClientGUIClick', getRootElement(), 
    function(button, state, absoluteX, absoluteY) 
        if(source == button1)then 
            ... 
         end 
    end 
end) 

How can I define who pressed the button? Like getting "theplayer" variable.

  
if getElementData(thePlayer, "dbid") == nil then 
    setElementData(thePlayer, "dbid", 1) 
end 
  

Why this is not working? I did not define "dbid" anywhere before, but isn`t returned value not existant / nil ?

  
function testejam(thePlayer, command) 
    local pid = tonumber(getElementData(thePlayer, "dbid")) 
    outputChatBox("Your ID:"..pid..".", thePlayer, 255, 255, 0) 
    local ciga = getElementData ( thePlayer, "dbid" ) 
    destroyElement(markeritis) 
    markeritis = createMarker ( blueBerryRally[ciga][1], blueBerryRally[ciga][2], blueBerryRally[ciga][3], "checkpoint", 6, 190, 156, 252, 170 ) 
    setElementData ( thePlayer, "dbid", getElementData ( thePlayer, "dbid" ) + 1 ) 
    addEventHandler( "onMarkerHit", markeritis, testejam ) 
end 
addCommandHandler("race", testejam) 
  

Why does it give error: attempt to concatenate local 'pid' (a nil value) ?

How can I determen if there is no more checkpoints left? Should I use if (markeritis == false) then ?

Thanks for your replys, time and help!

1. It's quite simple, since the code is client side, you use "localPlayer".

2. Is 'thePlayer' defined? check what 'dbid' returns.

3. It's because 'pid' is a nil value, it has no data in it. About the checkpoints, I think you can do somethling like:

#blueBerryRally == ciga
