onClientRender

[Drakath]

So, I'm making a Speedometer script and I keep getting this error: "addEventHandler: 'onClientRender' with this function is already handled"

function speed ( ) 
    addEventHandler ( "onClientRender", root, draw ) 
end 
addEventHandler ("onClientVehicleEnter", root, speed) 
  
function hideSpeed ( ) 
    removeEventHandler ( "onClientRender", root, draw ) 
end 
addEventHandler("onClientVehicleExit", root, hideSpeed) 
  
function draw ( ) 
        --this is where I have dxdraw stuff. 
    end

function speed (player) 
    if player == localPlayer then 
        addEventHandler ( "onClientRender", root, draw ) 
    end 
end 
addEventHandler ("onClientVehicleEnter", root, speed) 
  
function hideSpeed (player) 
    if player == localPlayer then 
        removeEventHandler ( "onClientRender", root, draw ) 
    end 
end 
addEventHandler("onClientVehicleExit", root, hideSpeed) 
  
function draw ( ) 
        --this is where I have dxdraw stuff. 
    end

why can't do it easyer? :3

function draw() 
     if ( isPedInVehicle ( localPlayer ) == false ) then return end 
     --this is where I have dxdraw stuff. 
end 
addEventHandler ( "onClientRender", root, draw )

TAPL's method worked. Thanks.

Simply because it uses more memory. The easy way isn't always the best way.

Even so, his version can get bugged, while yours can't.

So the best result will be: onVehicleEnter + render check if he is in the vehicle else remove the handler.

A combination would be the best.
