[HELP] Table Error

[ViRuZGamiing]

Hi guys,

as the title says how can I get the marker created in a function to work as event handler.

function startTrainJob (localPlayer) 
    local sv = trainTable 
    for i=1,#sv do 
        local trainTable = sv[i] 
        local vehicle = createVehicle (trainTable["create"][1], trainTable["create"][2], trainTable["create"][3], trainTable["create"][4],trainTable["create"][5], trainTable["create"][6],trainTable["create"][7])  
        setVehicleLocked (vehicle, true) 
        setTrainDirection (vehicle, true) 
        local finishMarker = createMarker (trainTable["marker"][1], trainTable["marker"][2], trainTable["marker"][3], "checkpoint", 6, 255, 150, 0, 255, localPlayer) -- Size 6 
        local finishBlip = createBlip (trainTable["marker"][1], trainTable["marker"][2], trainTable["marker"][3], 56, 2, 255, 0, 0, 255, 0, 10000, localPlayer) 
        setTrainDerailable(vehicle, false) 
         
        trainData[vehicle] = { 
            ["money"]=trainTable["money"], 
            ["spawn"]=trainTable["spawn"], 
            ["marker"]=trainTable["marker"] 
        } 
         
        trainTable["train"] = vehicle 
        trainTable["blip"] = finishBlip 
        trainTable["finishmarker"] = finishMarker 
         
        warpPedIntoVehicle (localPlayer, vehicle) 
    end 
end 
addEvent("startTrainJob", true) 
addEventHandler("startTrainJob", root, startTrainJob, localPlayer) 
  
function getPaid (thePlayer) 
    if data then 
        local price = data["money"] 
        givePlayerMoney (thePlayer, price) 
        destroyElement (unpack(trainTable["finishmarker"])) 
        destroyElement (unpack(trainTable["blip"])) 
        destroyElement (unpack(trainTable["train"])) 
        local spawn = data["spawn"] 
        setElementPosition(thePlayer, unpack(data["spawn"])) 
    end 
end 
  
addEventHandler("onMarkerHit", finishMarker, getPaid) 

No error's except; expected element at arg. 2, got nil

but that's quite normal as it not created yet.

I've also tried to place the event handler in the function but that didn't work.

Be more specific on error, which line

[ViRuZGamiing]

addEventHandler("onMarkerHit", finishMarker, getPaid) 

Line 40, finishMarker not found

I'm not sure how you managed to get a warning related to 'getVehicleOccupant', since I don't see it inside your script. Not at line 52, at least. As for 'unpack', that's obvious:

trainData[vehicle] = { 
            ["money"]=trainTable["money"], 
            ["spawn"]=trainTable["spawn"], 
            ["marker"]=trainTable["marker"], 
            ["train"] = vehicle, 
            ["blip"] = finishBlip, 
            ["finishmarker"] = finishMarker 
        } 
  
destroyElement (unpack(trainTable["finishmarker"])) 
            destroyElement (unpack(trainTable["blip"])) 
            destroyElement (unpack(trainTable["train"])) 

trainTable["finishmarker"], trainTable["blip"] and trainTable["train"] are elements and you're passing them to 'unpack'.

Also, I don't know what this thing means:

addEventHandler("startTrainJob", root, startTrainJob, localPlayer) 

'localPlayer' is nil on the server-side (unless you assign anything to this variable yourself, of course) and 'addEventHandler' takes a boolean as 4th argument, but this argument is about propagation, and I don't think it's related to whatever you're trying to do.

localPlayer = It comes from Client Side as an trigger argument and works fine

And yes I do have getVehicleOccupant but I added it after I uploaded code. (only thing changed)

The problems is in the tables mainly. I don't understand them 100%

The event handler error is pretty obvious.

Just add the event when the marker is created, or remove the local from it.

'localPlayer' outside functions doesn't come from anywhere. It's nil in that line where 'addEventHandler' is called.

And I don't know what tables you're talking about. The problem is exactly not that - 'unpack' takes a table as an argument, but you're passing an element.

[ViRuZGamiing]

An server side event trigger by client side isn't able to use thePlayer, i've occured this error many times.

So the problem is the unpack, I should remove it.

You are writing it and if it is broken you still writing more, so you won't learn a damn about it.

So delete all your code and start again, begin with the startTrainJob function.

I will help you step by step, but only step by step.
