You can write your topic however you want, but you need to answer these questions:
- What do you want to achieve? Keep it simple and clear!
I’m trying to script a jumping mechanic for a vehicle.
- What is the issue? Include screenshots / videos if possible!
After the first jump, theres a tiny debounce then vehicle just stops working.

What solutions have you tried so far? Did you look for solutions on the Developer Hub?
I tried setting the CanCollide of wheels to true but that didin’t help. I couldn’t find anyone who had a similiar issue on the forum.
The code im using the make the vehicle jump:
function jump ()
if car.DriveSeat.Occupant then
for i ,v in pairs(car:GetChildren()) do
if v:IsA("BasePart") then
v:SetNetworkOwner(nil)
v:ApplyImpulse(v.Position + Vector3.new(0,20,0)* v:GetMass() * car.DriveSeat.Occupant.Parent.PrimaryPart:GetMass() * 1.1)
end
end
end
end
The vehicles movement script:
local stats = car.Configurations
local Raycast = require(script.RaycastModule)
local mass = 0
for i, v in pairs(car:GetChildren()) do
if v:IsA("BasePart") then
mass = mass + (v:GetMass() * 196.2)
end
end
local bodyPosition = car.Chassis.BodyPosition
local bodyGyro = car.Chassis.BodyGyro
--local bodyPosition = Instance.new("BodyPosition", car.Chassis)
--bodyPosition.MaxForce = Vector3.new()
--local bodyGyro = Instance.new("BodyGyro", car.Chassis)
--bodyGyro.MaxTorque = Vector3.new()
local function UpdateThruster(thruster)
-- Raycasting
local hit, position = Raycast.new(thruster.Position, thruster.CFrame:vectorToWorldSpace(Vector3.new(0, -1, 0)) * stats.Height.Value) --game.Workspace:FindPartOnRay(ray, car)
local thrusterHeight = (position - thruster.Position).magnitude
-- Wheel
local wheelWeld = thruster:FindFirstChild("WheelWeld")
wheelWeld.C0 = CFrame.new(0, -math.min(thrusterHeight, stats.Height.Value * 0.8) + (wheelWeld.Part1.Size.Y / 2), 0)
-- Wheel turning
local offset = car.Chassis.CFrame:inverse() * thruster.CFrame
local speed = car.Chassis.CFrame:vectorToObjectSpace(car.Chassis.Velocity)
if offset.Z < 0 then
local direction = 1
if speed.Z > 0 then
direction = -1
end
wheelWeld.C0 = wheelWeld.C0 * CFrame.Angles(0, (car.Chassis.RotVelocity.Y / 2) * direction, 0)
end
-- Particles
if hit and thruster.Velocity.magnitude >= 5 then
wheelWeld.Part1.ParticleEmitter.Enabled = true
else
wheelWeld.Part1.ParticleEmitter.Enabled = false
end
end
car.DriveSeat.Changed:connect(function(property)
if property == "Occupant" then
if car.DriveSeat.Occupant then
car.EngineBlock.Running.Pitch = 1
car.EngineBlock.Running:Play()
local player = game.Players:GetPlayerFromCharacter(car.DriveSeat.Occupant.Parent)
if player then
car.DriveSeat:SetNetworkOwner(player)
local localCarScript = script.LocalCarScript:Clone()
localCarScript.Parent = player.PlayerGui
localCarScript.Car.Value = car
localCarScript.Disabled = false
end
else
car.EngineBlock.Running:Stop()

end
end)
while true do

for i, part in pairs(car:GetChildren()) do

UpdateThruster(part)
end
end
if car.DriveSeat.Occupant then
local ratio = car.DriveSeat.Velocity.magnitude / stats.Speed.Value
car.EngineBlock.Running.Pitch = 1 + ratio / 4

else
