Hello. I am trying to make a mod that chances the behaviour of a pallet discharging with a lua script. I got the script to load in (The first debug message poped up) but i cant get the onLoad and onUpdate functions to work. Does anyone know what i did wrong.

---script----
PlanteraPallet = {}
print("PlanteraPallet script is loaded !") -- Debug message

function PlanteraPallet.prerequisitesPresent(specializations)
return true
end
function PlanteraPallet:registerFunctions(vehicleType)
SpecializationUtil.registerFunction(vehicleType, "updateDischargeState", PlanteraPallet.updateDischargeState)
end

function PlanteraPallet.registerEventListeners(vehicleType)

SpecializationUtil.registerEventListener(vehicleType "onLoad", PlanteraPallet)

SpecializationUtil.registerEventListener(vehicleType, "onUpdate", PlanteraPallet)
end



function PlanteraPallet:onLoad(savegame)
print("PlanteraPallet script is initialized!")
self.canDischarge = false
end

function PlanteraPallet:onUpdate(dt)
print('I am loaded')
self:updateDischargeState(dt)
-- Ensure discharge is controlled by `canDischarge`
if self.canDischarge then
print(" Discharge ENABLED")
self:setDischargeState(Dischargeable.DISCHARGE_STATE_OBJECT) -- Start discharging
self:raiseActive()
else
print("Discharge DISABLED")
self:setDischargeState(Dischargeable.DISCHARGE_STATE_OFF) -- Stop discharging
self:raiseActive()
end
end

function PlanteraPallet:updateDischargeState(dt)
if self.components ~= nil and self.components[1] ~= nil then
-- Get rotation in RADIANS
local x, y, z = getRotation(self.components[1].node)

-- Convert to DEGREES
local xDeg = math.deg(x)
local zDeg = math.deg(z)

-- Debugging: Show actual rotation
print(string.format("Pallet Rotation (Degrees): X=%.2f, Y=%.2f, Z=%.2f", xDeg, math.deg(y), zDeg))

-- Only allow discharge when X or Z is near 180°
if (math.abs(xDeg) > 170 and math.abs(xDeg) < 190) or (math.abs(zDeg) > 170 and math.abs(zDeg) < 190) then
self.canDischarge = true
print("Pallet is upside down. Can discharge.")
else
self.canDischarge = false
print(" Pallet is NOT upside down. No discharge.")
end
else
print(" Error: Could not retrieve pallet rotation.")
end
end
