A-Chassis car EXPLODING on teleportation

Help and Feedback Scripting Support
#1

I want to achieve the A-Chassis car teleporting properly. It works in studio, but it literally explodes in the game (wheels get yeeted everywhere and the car turns into a “garry’s mod glitching prop”). I think it might be the A-Chassis system itself, since I have tried a ton of variants to try and get it fixed, but nothing helped. I couldn’t find the documentation for A-Chassis too, so it’s even more annoying.

The teleporter works by checking if the object that touched it is a vehicle or not (by name or parent), and then if it’s a vehicle it’s checking if it has a primary part, and if it doesn’t have one it creates the part with model’s extent size, welds it and sets it as the primary part, then it’s changing the model’s primary part’s CFrame and after the teleport it deletes the primary part if it was created artificially.

It’s not the primary part model that is the problem, since even if there is a primary part it’s still getting yeeted, and the reason that it works in studio and doesn’t in actual player is because studio doesn’t have any latency, and somehow having slight latency breaks the whole thing.

Script:

local model = script.Parent
local tpSetupFailed = false

local teleportSettings = {
	touchMode = 0, -- Touch modes: 0 - triggerPad.Touched | 1 - triggerPad.TouchEnded (0 default, recommended)
	debounceTime = 1
}

local debounceList = {}

------- TriggerPad
local triggerPad = model:FindFirstChild("Pad")
if not triggerPad then tpSetupFailed = true warn("No trigger pad detected in "..model.Name.."!") end

------- LocationPads
local locationPads = {}
for _,pad in pairs(model:GetChildren()) do
	if pad:IsA("Part") and pad.Name == "ToPad" then
		table.insert(locationPads,pad)
	end
end
if #locationPads == 0 then tpSetupFailed = true warn("No location pads detected in "..model.Name.."!") end

------- Teleport Fail Check
if tpSetupFailed then error("Failed to setup for teleport "..model.Name.."!") end

------- Teleport
function teleport(object)
	if object.Parent:FindFirstChild("Humanoid") then
		for i,v in pairs(debounceList) do
			if v == object.Parent then return end
		end
		table.insert(debounceList,object.Parent)
		local humanoid = object.Parent:FindFirstChild("Humanoid")
		if humanoid and not humanoid.Sit and humanoid.Health > 0 then
			local randomPad = math.random(#locationPads)
			object.Parent:MoveTo(locationPads[randomPad].Position) 
		end
		wait(teleportSettings.debounceTime)
		for i,v in pairs(debounceList) do
			if v == object.Parent then table.remove(debounceList,i) end
		end
	end
	if object.Parent.Parent.Parent.Name == "Vehicles" then
		for i,v in pairs(debounceList) do
			if v == object.Parent.Parent.Parent then return end
		end
		table.insert(debounceList,object.Parent.Parent.Parent)
		local randomPad = math.random(#locationPads)
		if object.Parent.Parent.PrimaryPart then
			object.Parent.Parent:PivotTo(CFrame.new(locationPads[randomPad].CFrame.Position)) 
		else
			local newPP = Instance.new("Part")
			newPP.CanCollide = false
			newPP.Transparency = 1
			newPP.CFrame, newPP.Size = object.Parent.Parent:GetBoundingBox()
			object.Parent.Parent.PrimaryPart = newPP
			object.Parent.Parent:PivotTo(CFrame.new(locationPads[randomPad].CFrame.Position))
			newPP:Destroy()
		end
		wait(teleportSettings.debounceTime)
		for i,v in pairs(debounceList) do
			if v == object.Parent.Parent.Parent then table.remove(debounceList,i) end
		end
	end
end

------- Teleport Trigger Events
if teleportSettings.touchMode < 1 then
	triggerPad.Touched:Connect(function(object)
		teleport(object)
	end)
else
	triggerPad.TouchEnded:Connect(function(object)
		teleport(object)
	end)
end
Any way to make An A-chassis car teleport when it hits a part?

Try using :PivotTo instead of CFrame.

pivotto moves the whole model, cframe only rhe welded parts which does not move the wheel constraints.

It stopped “exploding”, but it’s still doing this

#4

hey, are you sure the body didn’t have any collision with the tires?
because it looks like the tires have gone into the body

You’re teleporting a model with physics still being applied. When you move a model, it doesn’t cancel the forces that are still applied.

A-Chassis uses AngularVelocity instances on the wheels (YMMV on older versions). You can set AngularVelocity and MaxTorque on the 4 wheels to simulate hard brakes. Not sure about the exact values since I’m typing this on mobile, but you can do some trial-and-error.
