How to calculate position front of the car.

I want to put ped on to the front of the car.

You need true in meta.xml

local position = vehicle.matrix.position + vehicle.matrix.forward * 3 
player:setPosition(position)

Thank you!

Can you answer one more question?

  
local duty = "Mechanic" 
  
setElementVisibleTo(player, dutyMarker) 
  

in ElementVisibleTo I want to replace the duty word.

How to do it?

Create a marker and use that. Could you explain your problem further?

[JanriKallas]

Lets say theres a three markers

MechanicMarker

MedicMarker

PoliceMarker

They are all invisible.

Then function makes one of the Marker visible that player chose from clientside.

So to not make three different function for policemarker, medicmarker, mechanicmarker

  
Function () --clientside 
duty = GuigetText (bla1) 
TriggerEvent ("serverfunc", localplayer, localplayer, duty) 
End 
  
Function (player,duty) --duty is "Mechanic" / "Medic" / "Police" 
setElementVisibleTo (player, ..duty..Marker) 
end 
  

I alrady tried: (tostring(duty)Marker) and tostring (duty)..Marker

[ALw7sH]

local markers = { 
["Mechanic"] = createMarker(...), 
["Medic"] = createMarker(...), 
["Police"] = createMarker(...), 
} 
  
function anFunction(player,duty) 
    setElementVisibleTo(markers[duty],player,true) 
    for k,v in pairs(markers) do 
        if k ~= duty then 
            setElementVisibleTo(v,player,false) 
        end 
    end 
end 
  
anFunction(getRandomPlayer(),"Police") 

Is that what you mean?

You actually don't need to enable OOP if you prefer not to use it. If you look at the wiki page of getElementMatrix you have this example which does exactly what you want;

function getPositionFromElementOffset(element,offX,offY,offZ) 
    local m = getElementMatrix ( element )  -- Get the matrix 
    local x = offX * m[1][1] + offY * m[2][1] + offZ * m[3][1] + m[4][1]  -- Apply transform 
    local y = offX * m[1][2] + offY * m[2][2] + offZ * m[3][2] + m[4][2] 
    local z = offX * m[1][3] + offY * m[2][3] + offZ * m[3][3] + m[4][3] 
    return x, y, z                               -- Return the transformed point 
end 
  
-- Get the position of a point 3 units to the right of the element: 
x,y,z = getPositionFromElementOffset(element,3,0,0) 
  
-- Get the position of a point 2 units in front of the element: 
x,y,z = getPositionFromElementOffset(element,0,2,0) 
  
-- Get the position of a point 1 unit above the element: 
x,y,z = getPositionFromElementOffset(element,0,0,1)
