I am currently making a cart ride cart with working suspension, however when the cart begins moving it starts moving straight away, rather than accelerating up to the max speed like an ordinary car, heres my original code which moves the cart back and forward:
local seat = cart.VehicleSeat
local backLeft = cart.LB
local backRight = cart.RB
local frontLeft = cart.LF
local frontRight = cart.RF
local speed = 35
seat:GetPropertyChangedSignal("Throttle"):Connect(function ()
frontLeft.Wheel.WheelContraint.AngularVelocity = -speed * seat.Throttle
frontRight.Wheel.WheelContraint.AngularVelocity = speed * seat.Throttle
backLeft.Wheel.WheelContraint.AngularVelocity = -speed * seat.Throttle
backRight.Wheel.WheelContraint.AngularVelocity = speed * seat.Throttle
end)
As you can see by the recording the moving is very janky and if spammed can even throw the player of the track!
The easiest way to achieve what you’re looking for is by using interpolation
@sleitnick posted a well-constructed tutorial for cars, which I recommend you follow. Here’s part 4 of his multi-part series, where he goes over the client script. You don’t need to follow it exactly but he uses interpolation in order to achieve that smooth acceleration and deceleration, which should solve your issue!
If you have any questions or concerns, don’t hesitate to ask!
i dont know whether i have done it correctly, heres a video to show you if i have followed it correctly aswell with the new script, it doesnt look like it has changed anything?
local seat = cart.VehicleSeat
local backLeft = cart.LB
local backRight = cart.RB
local frontLeft = cart.LF
local frontRight = cart.RF
seat:GetPropertyChangedSignal("Throttle"):Connect(function ()
local throttle = seat.ThrottleFloat
local torque = seat.Torque
local speed = seat.MaxSpeed * throttle
frontLeft.Wheel.WheelContraint.MotorMaxTorque = torque
frontRight.Wheel.WheelContraint.MotorMaxTorque = torque
backLeft.Wheel.WheelContraint.MotorMaxTorque = torque
backRight.Wheel.WheelContraint.MotorMaxTorque = torque
frontLeft.Wheel.WheelContraint.AngularVelocity = -speed
frontRight.Wheel.WheelContraint.AngularVelocity = speed
backLeft.Wheel.WheelContraint.AngularVelocity = -speed
backRight.Wheel.WheelContraint.AngularVelocity = speed
end)```
It hasn’t changed because you didn’t change the speed part
His speed handler looks like this:
local ThrottleGoal = Seat.ThrottleFloat
Throttle += (ThrottleGoal - Throttle) * math.min(Delta * Seat.TurnSpeed, 1)
local Torque = Seat.Torque
local Speed = Seat.MaxSpeed * Throttle
Converting this to your script would look something like this
local RunService = game:GetService("RunService")
local Seat = Cart.VehicleSeat
local BackLeft = cart.LB
local BackRight = cart.RB
local FrontLeft = cart.LF
local FrontRight = cart.RF
local Throttle = 0
RunService.RenderStepped:Connect(function(Delta)
local ThrottleGoal = Seat.ThrottleFloat
Throttle += (ThrottleGoal - Throttle) * math.min(Delta * Seat.TurnSpeed, 1)
local Torque = Seat.Torque
local Speed = Seat.MaxSpeed * Throttle
-- apply the speed & torque to the wheels here
end)
The whole point of interpolation is to achieve a value smoothly, which is why you add to the throttle incrementally (to get the smooth acceleration & deceleration). You can also print the Throttle value in order to see it go up/down smoothly, if you wish
