[Tutorial] Creating a marker for random vehicles [Tutorial]

[novo]

Hi all.

Today i'll learn you how to create a marker for random vehicles.

This idea is taken from a Mr. Green's map.

Let's begin...

1. You must get all IDs that you want to use. You can see all vehicles ID's here: https://wiki.multitheftauto.com/wiki/Vehicle_IDs#2-Door_and_Compact_cars

2. I'll use all vehicles in mta.

3. Now, let's create the marker:

marker = createMarker(1314,-1575,12,"corona",2,0,255,0) 

You must change "1314,-1575,12" for the x,y,z of where you want to locate the marker.

4. Now, we add a handled function that will happen when player (source) hits the marker:

addEventHandler("onClientMarkerHit",marker, 
function() 
    local vh = getPedOccupiedVehicle ( source ) 
    vehicles = { --[[YOUR ID'S HERE, SEPARATED BY A COMA (Ex: 1, 2, 3)]] } 
    nm = tonumber ( math.random( #vehicles ) ) 
    setElementModel ( vh, nm )   
end)  
  
  
  
  
  
  

5. Finally, we gotta put together these two codes, like this:

marker = createMarker(x, y, z,"corona",2,0,255,0) 
  
addEventHandler("onClientMarkerHit",marker, 
function() 
    local vh = getPedOccupiedVehicle ( source ) 
    vehicles = { --[[YOUR ID'S HERE, SEPARATED BY A COMA (Ex: 1, 2, 3)]] } 
    nm = tonumber ( math.random( #vehicles ) ) 
    setElementModel ( vh, nm )   
end)  
  
  
  

6. Save that code as "client.lua" into the map folder.

7. Open the file meta.xml located inside the map folder.

8. Add at the beginning below this code:

<script src="client.lua" type="client" /> 

9. Save the meta.xml

10. We finished.

NOTE: THIS CODE WASN'T TESTED YET, IF YOU HAVE PROBLEMS WITH IT TELL IT TO ME WITH A REPLY.

I hope you like it!

Bye

Wong place, we got a tutorials section...

Nice tut but instead of writing comments in a string inside the variable you could just do --Comment here behind the variable...

Topic moved to: "Scripting > Tutorials" section.

marker = createMarker(x, y, z,"corona",2,0,255,0) 
  
addEventHandler("onClientMarkerHit",marker, 
function() 
    local vh = getPedOccupiedVehicle ( source ) 
    vehicles = { --[[YOUR ID'S HERE, SEPARATED BY A COMA (Ex: 1, 2, 3)]] } 
    nm = tonumber ( math.random( #vehicles ) ) 
    setElementModel ( vh, nm )   
end)  
  
  
  

It has a few errors

• source in getPedOccupiedVehicle is the marker, not the player.
  

•     nm = tonumber ( math.random( #vehicles ) ) 
      setElementModel ( vh, nm )   
  

  
  This picks a random number from 1 to count of table, not a random vehicle model. It should be something like:
  

  nm = tonumber(vehicles[math.random(#vehicles)]) 
  

[qaisjp]

Also the table shouldn't be declared on every hit, declare it at the start of the code. Use locals.

It appears no one in MTA knows how to speak good English but Karthik.

Posting untested (and error-riddled) code in a Tutorial section is probably not something you want to do.

I mean, effort appreciated and all, but seriously, this won't help anyone. Testing such a basic script wouldn't take much time, either.

[qaisjp]

It appears no one in MTA knows how to speak good English but Karthik.

lol, 1) That was totally offtopic 2) I'm pretty sure I have great English 3) He is indian 4) OThers can speak perfect english too.

God, chris e_e!

It appears no one in MTA knows how to speak good English but Karthik.

Ironic, the correct phrasing would be;

It appears that nobody in the MTA community speaks good English, except 'Karthik'.

[qaisjp]

Put 'Karthik' within quotations isn't required though as he wasn't referencing a common noun.

[Callum]

Nobody knows for a fact that Karthik is his name though.

[qaisjp]

But that IS his nickname

Can someone re write this tutorial 4 me! And message me it. It would be greatley appreciated.

[dazzlepoint]

what did i wrong ? can you help me ?

marker = createMarker(2121, 1402, 10,"cylinder",2,0,255,0)

addEventHandler("onClientMarkerHit",marker,

function()

local vh = getPedOccupiedVehicle ( source )

vehicles = 4, 3, 1

nm = tonumber ( math.random( #vehicles ) )

setElementModel ( vh, nm )

end)

[iPrestege]

-- # Client Side 
local marker = createMarker(2121, 1402,10,"cylinder",2,0,255,0) 
  
addEventHandler("onClientMarkerHit",marker, 
    function ( player ) 
        if getElementType ( player ) == "player" then  
            local vehicle =  getPedOccupiedVehicle ( player ) 
             if not vehicle then return end 
            local vehicles =  { 411,412,413 } 
            local ID = (vehicles[math.random(#vehicles)]) 
            setElementModel ( vehicle, ID )  
    end 
end,false 
) 

Erros :

-- You're entered id was wrong

-- Check the vehicle with a source element ?

-- Get a random model was wrong .

[dazzlepoint]

hi #Mr.Pres[T]ege you are really PRO but is this also for the server side

-- # Client Side 
local marker = createMarker(2121, 1402,10,"cylinder",2,0,255,0) 
  
addEventHandler("onClientMarkerHit",marker, 
    function ( player ) 
        if getElementType ( player ) == "player" then  
            local vehicle =  getPedOccupiedVehicle ( player ) 
             if not vehicle then return end 
            local vehicles =  { 411,412,413 } 
            local ID = (vehicles[math.random(#vehicles)]) 
            setElementModel ( vehicle, ID )  
    end 
end,false 
) 

Erros :

-- You're entered id was wrong

-- Check the vehicle with a source element ?

-- Get a random model was wrong .

No it's only client side you can use this server side :

-- # Server Side 
local marker = createMarker(2121, 1402,10,"cylinder",2,0,255,0) 
  
addEventHandler("onMarkerHit",marker, 
    function ( player ) 
        if getElementType ( player ) == "player" then  
            local vehicle =  getPedOccupiedVehicle ( player ) 
             if not vehicle then return end 
            local vehicles =  { 411,412,413 } 
            local ID = (vehicles[math.random(#vehicles)]) 
            setElementModel ( vehicle, ID )  
    end 
end,false 
)

Greetings, I have followed your steps but unfortunately, nothing happened, even the ' debug script 3 '  did not inform me if there are errors!

Here is my work: 

Client.lua:

Spoiler

 

marker = createMarker(2226, 1512, 10, "corona",2,0,255,0)

addEventHandler("onClientMarkerHit",marker,
function()
local vh = getPed0ccupiedVehicle ( source )
vehicles = { 4, 1, 0 }
nm = tonumber ( math.random( #vehicles ) )
setElementModel ( vh, nm )
end)

 

 

 

meta.xml file:

Spoiler

<script src="client.lua" type="client" />

 

What is the wrong?!

Hi Petey99,

Keep in mind that the command does not have any spaces. You should type in:

/debugscript 3

You will also find that you typed getPed0ccupiedVehicle, and not getPedOccupiedVehicle.

 

Does that help?
