[Help] Change spoilers on mouse scrolling

[Daniels69]

i'm trying to make an script: when player scrolls down the mouse, the spoilers change.

and it doesn't work , i don't really know where is the problem , and what did i do wrong.

client:

function checkifkeyup() 
  
    if getKeyState( "lctrl" ) == true  then 
triggerServerEvent("changespoiler",localPlayer,localPlayer) 
  
    end 
end 
bindKey( "mouse_wheel_up", "down",  checkifkeyup ) 
  
  

server:

local spoilers = { 
1000, 
1001, 
1002, 
1003, 
1014, 
1015, 
1016, 
  
} 
addEvent("changespoiler",true) 
function spoilerdown(thePlayer) 
  
     local theVehicle = getPedOccupiedVehicle ( source ) 
    if theVehicle  == true then  
             local theVehicle = getPedOccupiedVehicle ( source ) 
  
             addVehicleUpgrade ( theVehicle, spoilers+1 ) 
  
        else 
            addVehicleUpgrade ( theVehicle, math.random(#spoilers)) 
        end 
    end 
  
  
addEventHandler("changespoiler",getRootElement(),spoilerdown) 
  
  

Thank you

Not tested and not sure if it'll work at all

    spoilers = { 
    1000, 
    1001, 
    1002, 
    1003, 
    1014, 
    1015, 
    1016, 
      
    } 
     
    Current = 1 
    addEvent("changespoiler",true) 
    function spoilerdown(thePlayer) 
      
         local theVehicle = getPedOccupiedVehicle ( source ) 
          
         if Current < #spoilers then  
         Current = Current+1  
         else 
         Current = 1 
         end 
          
        if theVehicle true then 
                 addVehicleUpgrade ( theVehicle, spoilers(Current) ) 
            end 
        end 
      
      
    addEventHandler("changespoiler",getRootElement(),spoilerdown)

doesn't work. and there's no errors o.0

The issue with your original code is here:

addVehicleUpgrade ( theVehicle, spoilers+1 ) 

spoilers is defined as a table in your code and in this line you're trying to +1 to the table which isn't possible.

To choose a random spoiler from the list: spoilers[math.random(1, #spoilers)]

To cycle through each one, start by defining the current spoiler it's on as seen in the script provided above. Each time you trigger changespoiler you want to add 1 to the current spoiler variable but if it hits #spoilers+1 then reset it to 1. That way each time you trigger changespoiler it will cycle through the list of parts in your spoilers table.
