Chassis is not moving

Help and Feedback Scripting Support
#1

Hi. I am making a chassis for a test, everything is working just fine, but the only problem I am getting is that the Chassis cannot move, but tires can rotate when pressing A/D. The constraint I am using to move the chassis is Cylindrical Constraint, and its AngularActuatorType is Motor, the AngularVelocity is getting applied, but the chassis just don’t move, everything is unanchored. Help is appreciated :slight_smile:
Here’s the code:

local stop = script.Stop

local seat = Car.VehicleSeat;
local attFL = Car.Platform.AttachmentFL
local attFR = Car.Platform.AttachmentFR

local maxSteeringAngle = 30

local cyFL = Car.Platform.CylindricalFL
local cyFR =  Car.Platform.CylindricalFR
local cyRL =  Car.Platform.CylindricalRL
local cyRR =  Car.Platform.CylindricalRR

local steer = 0
local throttle = 0

local heartbeat

local function Update(dt)
    
    local steerGoal = -seat.SteerFloat * maxSteeringAngle;
    steer = steer + (steerGoal - steer) * math.min(dt * seat.TurnSpeed, 1) 
    attFL.Orientation = Vector3.new(0, steer, -90)
    attFR.Orientation = Vector3.new(0, steer, -90)
    
    local throttleGoal = seat.ThrottleFloat;
    throttle = throttle + (throttleGoal - throttle) * math.min(dt * seat.TurnSpeed)
    local torque = seat.Torque
    local speed = seat.MaxSpeed * throttle
    cyFL.MotorMaxTorque = torque
    cyFR.MotorMaxTorque = torque
    cyRL.MotorMaxTorque = torque
    cyRR.MotorMaxTorque = torque
    cyFL.AngularVelocity = speed
    cyFR.AngularVelocity = -speed
    cyRL.AngularVelocity = speed
    cyRR.AngularVelocity = -speed
    
end

local function Start()
    print("Start client")
    heartbeat = game:GetService("RunService").Heartbeat:Connect(Update)
end

local function Stop()
    print("Stop Client")
    heartbeat:Disconnect()
    script:Destroy()
end


Start()
if (stop.Value) then
    Stop()
    return
end
stop.Changed:Connect(function(shouldStop)
    if (not shouldStop) then return end
    Stop()
end)

I usually use hinge for a car chassis. And set hinge mode into motor.

Any error in the output?That could help.

There’s no error in the output, let me recheck.

Could you show the screenshot of the 4 Cylindrical Constraints properties? Don’t see any issue in the code.

I meant the Properties of each of them, as said in my post.

I feel like the problem is with the InclinationAngle, the FL and RL One’s should be 90 and FR and RR should be -90.

Okay, let me change them real quick.

Nope, still not working, it should be working but it isn’t.

If everything else is working, then I would say you should check if increasing the Torque may help. If not then just ensure once more that each and every part is unanchored.

Yeah, everything else is working, tires are rotating when pressed A/D, and the angular velocity is also getting applied to the constraint. Let me check

Thanks a lot man, you’ve helped me a lot. I increased the torque, and now it’s working. I just did torque^2 lol. Thank you so much :smiley:
