Hi, I’m trying to get a vehicle to simulate physics properly when you get into a vehicle seat.
Currently, if I hop on the seat it will propel itself forward for 2-3 seconds, not allowing vehicle seat input to change it. Then it will finally give control to the player and stop propelling forward.
I’ve tried setting Network Ownership, but that doesn’t fix it.
local VehicleSeat = script.Parent
local JetskiModel = VehicleSeat.Parent
local BodyGyro = JetskiModel.PrimaryPart:WaitForChild("BodyGyro")
local Speed = VehicleSeat:GetAttribute("Speed")
local Range = 15
BodyGyro.CFrame = JetskiModel.PrimaryPart.CFrame
JetskiModel.PrimaryPart.BodyPosition.position = JetskiModel.PrimaryPart.Position
local function LERP(origin, target, percent)
return origin + (target-origin)*percent
end
local function adjustThrottle()
if VehicleSeat.Throttle == 1 or VehicleSeat.Throttle == -1 then
VehicleSeat.Parent.Fire.ParticleEmitter.Enabled = true
else
VehicleSeat.Parent.Fire.ParticleEmitter.Enabled = false
end
end
VehicleSeat:GetPropertyChangedSignal("Throttle"):Connect(function()
adjustThrottle()
end)
VehicleSeat:GetPropertyChangedSignal("Steer"):Connect(function()
adjustThrottle()
end)
VehicleSeat.Changed:Connect(function(prop)
if prop == "Occupant" then
local humanoid = VehicleSeat.Occupant
if humanoid then
local player = game:GetService("Players"):GetPlayerFromCharacter(humanoid.Parent)
if player then
VehicleSeat:SetNetworkOwner(player)
end
else
VehicleSeat:SetNetworkOwnershipAuto()
end
end
end)
game:GetService("RunService").Heartbeat:Connect(function(deltaTime)
local CurrentSpeed = VehicleSeat.CFrame:VectorToObjectSpace(VehicleSeat.AssemblyLinearVelocity).Z*-1
local Pitch = 0.15 + (CurrentSpeed / Speed)
local Direction = VehicleSeat.CFrame.LookVector
if VehicleSeat.Steer == 1 then
BodyGyro.CFrame = BodyGyro.CFrame * CFrame.fromEulerAnglesXYZ(0,-0.04*Pitch,0)
elseif VehicleSeat.Steer == -1 then
BodyGyro.CFrame = BodyGyro.CFrame * CFrame.fromEulerAnglesXYZ(0,0.04*Pitch,0)
end
JetskiModel.PrimaryPart.BodyVelocity.Velocity = Direction * LERP(CurrentSpeed, Speed * math.clamp(VehicleSeat.Throttle, -0.3,1), 0.1)
end)
i guess to make the vehicle to be stationary for a few second might be anchoring the vehicle when player enters then wait few seconds tgen unanchor the vehicle
That would require me to convert it into a LocalScript (or Module Script), as RenderStepped can only be run from the Client.
If I convert it to a Local Script or Module Script, I would have to run it from a different place than the Vehicle, as Client scripts are only ran from a select few places in the Explorer.
I would have to restructure the entire code to do this.
I did try an infinite wait loop instead of HeartbeatService, but the results are still the same, making me wonder if RenderStepped wouldn’t just be a dead end and waste of time restructuring my entire code to do it.
But you are right about the NetworkOwner. I thought that was the case, but put it in just to be sure.
But the problem still remains. For 2 to 3 seconds after gettting into the seat, I cannot control it’s turning, and its speed doesn’t work properly.
while true do
wait()
local CurrentSpeed = VehicleSeat.CFrame:VectorToObjectSpace(VehicleSeat.AssemblyLinearVelocity).Z*-1
local Pitch = 0.15 + (CurrentSpeed / Speed)
local Direction = VehicleSeat.CFrame.LookVector
if VehicleSeat.Steer == 1 then
BodyGyro.CFrame = BodyGyro.CFrame * CFrame.fromEulerAnglesXYZ(0,-0.04*Pitch,0)
elseif VehicleSeat.Steer == -1 then
BodyGyro.CFrame = BodyGyro.CFrame * CFrame.fromEulerAnglesXYZ(0,0.04*Pitch,0)
end
BodyVelocity.Velocity = Direction * LERP(CurrentSpeed, Speed * math.clamp(VehicleSeat.Throttle, -0.3,1), 0.1)
end
it seems youre checking the throttle update using getpropertychangesignal as ive heard this function is not reliable when making this kind of script i reccomend making it as a while wait loop
Actually that’s a little misleading. If you take a closer look, you’ll see GetPropertyChangedSignal is only used to enable and disable a particle emitter. I use to do it that way, but stopped using it. It still has the name AdjustThrottle for the function tho.
im quite surprised why you making everything complicated what you can do is
while wait(.1) do
if Seat.Throttle ==1 then
--move forward
elseif Seat.Throttle == -1 then
--move backward
elseif Seat.Throttle == 0 then
--stop movement
elseif Seat.Throttle == 1 then
--go right
elseif Seat.Throttle == -1 then
--go left
elseif Seat.Throttle == 0 then
--stop steer
end
My current system has proper slowing down and speeding up. Systems that use the setup you’ve offered tend to stop immediately when an input stops. For water based vehicles, or really vehicles in general, this is awkward.
It’s possible I can attempt to convert the system you’re suggesting with my more closely simulated system, but idk if that will fix it or work.
I am appreciating the brainstorming and help though. I did look into that system. Infact its what I started with before making adjustments to get better simulation.
also i have heard that body velocity just makes a vehicle go super fast try using body force
because body force makes the vehicle to go fast slowly just like a real vehicle
It doesn’t make vehicles (or objects) go super fast.
I think you’ve been misinformed.
It makes it go at a constant velocity, which might be what you mean. But the LERP function I have tells it to gradually speed up. LERP is just a fancy math that says get the % point from A to B. So 10% from 1 to 100 is 10, so it gets 10.
I use this to slowly reach a closer and closer point to the max speed over time.
