Solved Problem with calling a function in mainlevel.lua

Helo. I made this kind of code and it seems I did something wrong with calling my function, because my map can't load anymore. I've tested it out and it seems the function itself doesn't cause any trouble but only when I try to call it. The script is rather simple, there is a timer for 4 cars (2 of each team) which forces vehicles on the map to keep moving, to avoid blocking / stopping / going too slow and resets a parcticular vehicle when it doesn't move for 3 seconds. Maybe I shouldn't script it in mainlevel.lua? It's quite obvious there is always a better solution.

Code:

local M ={}

--Red Team
local firstRedCar
local secondRedCar

--Blue Team
local firstBlueCar
local secondBlueCar

--Timers
local moveTimer = {0, 0, 0, 0}
local startMoveTimer = {false, false, false, false}

local function onClientStartMission()
    --car initialization
    firstRedCar = scenetree.findObject("car_red1")
    secondRedCar = scenetree.findObject("car_red2")

    firstBlueCar = scenetree.findObject("car_blue1")
    secondBlueCar = scenetree.findObject("car_blue2")
end

local function stopCars(car, idx)

    if car:getVelocity().x == 0 or car:getVelocity().y == 0 then
        startMoveTimer[idx] = true
        end
        
    if startMoveTimer[idx] then
        moveTimer[idx] = moveTimer[idx] + dt else
        moveTimer[idx] = moveTimer[idx]
        end
        
            if moveTimer[idx] >= 3 then
            car:requestReset()
            moveTimer[idx] = 0
        end
        
    if car:getVelocity().x > 0.1 or car:getVelocity().y > 0.1 then
        moveTimer[idx] = 0
        end
    return 0
end

local function onUpdate(dt)
    --Calling a function for each car
    stopCars(firstRedCar, 0)
    stopCars(secondRedCar, 1)

    stopCars(firstBlueCar, 2)
    stopCars(secondBlueCar, 3)
end
 
 
M.onClientStartMission = onClientStartMission
M.onUpdate = onUpdate
return M

 

I just realized there is no 0 index in lua, but I changed it and it didn't solve the problem so need to keep looking

 

In order to call a function from another file you need to also list it in the public interface (usually down at the bottom).
In this case you need:

Code:

M.onClientStartMission = onClientStartMission
M.onUpdate = onUpdate
M.stopCars = stopCars

You can then call mainLevel.stopCars(args) from e.g. a lua trigger.

 

Thank you so much! That's really valuable knowledge
