Cancel createMarker

Lloyd Logan · January 25, 2013

Hey, so i made a random marker, and you drive to the marker (this marker is created randomly) and pick up the created ped. When you do the marker is destroyed. The problem is, i have 2 tables, one to pick up the ped(in the table there is co-ordinates for the random marker), the other one is where to drop the ped off. The problem i am have is that when i pick up a ped it creates another pick up ped marker. How do i cancel it creating another marker?

Check the element type of "thePlayer" at "inVEH" function.

Check the element type of "thePlayer" at "inVEH" function.

You do know what I mean by my post?

Castillo · January 25, 2013

You are saying that a random marker is generated again because the ped enters the vehicle, that's what I got at least.

Lloyd Logan · January 25, 2013

You are saying that a random marker is generated again because the ped enters the vehicle, that's what I got at least.

So, i create a random marker for the player to pick a ped up at, this marker is random

Then, When the player hit the marker the ped is warped into the veh then the DROP OFF marker is displayed, problem is I don't know how to stop it creating another PICK UP marker aswell.

Castillo · January 25, 2013

I told you on my first post, check if the element that entered the vehicle is a player.

getElementType

Lloyd Logan · January 25, 2013

I told you on my first post, check if the element that entered the vehicle is a player.
getElementType 

I dont that, What i mean is, the player is already in the vehicle , it IS creating the DROP OFF marker, but it is also creating the PICK UP MARKER, Which shouldn't be made until the DROPOFF marker has been hit.

You are my saviour!

Castillo · January 25, 2013

Did it work?

Lloyd Logan · January 25, 2013

Can I quickly ask, is getElementsByType all you added in there?

And yes it works! How then would get it, after the dropoff has been made, to create another pickup marker?

And again Thank You!

Castillo · January 25, 2013

I changed some other things.

To do that, you need to do the same as in "inVEH" function, destroy first marker/blip, create new random one and attach the event handler of "onMarkerHit" to function "pickMeUp".

Thanks, I will try that now Castillo.

It says Bad argument at 2, expected element got nil, markers [ thePlayer ] is the element of the marker, yes?

A quick question Castillo, how do I make the script happen again, I tried

triggerEvent("onVehicleEnter", root)

But it didn't trigger it?

Castillo · January 26, 2013

You can create a function instead, and execute it when they enter the vehicle, and when they finish delivery.

Lloyd Logan · January 26, 2013

If i have created my function how would I execute it when they enter the vehicle the finish the job?

Castillo · January 26, 2013

This would be the main function:

function startJob ( thePlayer ) 
    -- Code here 
end

And you would need to put your random marker generation inside it, then execute startJob passing 'thePlayer' argument from 'onVehicleEnter' and 'onMarkerHit'.

Lloyd Logan · January 26, 2013

Okay, i give up , I have no idea any more

Castillo · January 26, 2013

            local x, y, z = unpack ( pickups [ math.random ( #pickups ) ] ) 
            markers [ thePlayer ] = createMarker ( x, y, z, "cylinder", 3.5, 255, 0, 0 ) 
            local skins = unpack ( pedCus [ math.random ( #pedCus ) ] ) 
            peds [ thePlayer ] = createPed( skins, x, y, z ) 
            blips [ thePlayer ] = createBlipAttachedTo ( markers [ thePlayer ], 41 ) 
            addEventHandler ( "onMarkerHit", markers [ thePlayer ], warpit )

That's what it has to go inside startJob function.

From my other functions?
