How would I make this boat turn work?

So I want to make a boat turn and if it is moving then it will turn and move in that direction.

But, whenever it turns any direction, the boat starts turning back forward.

Here is my script:

local dss = game:GetService("DataStoreService")
local leaderstatsStore = dss:GetDataStore("LeaderstatsData1")
local boatsStore = dss:GetDataStore("BoatsData1")

local TS = game:GetService("TweenService")
local TInfo = TweenInfo.new(10,Enum.EasingStyle.Linear,Enum.EasingDirection.Out,0,false,0)

local event = game.ReplicatedStorage.Moving
local turnEvent = game.ReplicatedStorage.TurnAction
local newBoatEvent = game.ReplicatedStorage.NewBoat
local submergeEvent = game.ReplicatedStorage.Submerge

local players_moving = {}
local boat_tweens = {}

local savedBoats = game.ServerStorage.SavedBoats

local function findBoat(plr)
	for i, boat in pairs(workspace.Boats:GetChildren()) do
		if boat.Owner.Value == plr.Name then
			return boat
		end
	end
	return nil
end

game.Players.PlayerAdded:Connect(function(plr)
	players_moving[plr.Name] = false
	
	local boat = nil
	boat = boatsStore:GetAsync(plr.UserId)
	
	if boat ~= nil then
		local newBoat = savedBoats:WaitForChild(boat):Clone()
		newBoat.Parent = workspace.Boats
		newBoat.Owner.Value = plr.Name
		
		local randomDock = workspace.Docks:GetChildren()[math.random(1,#workspace.Docks:GetChildren())]
		if randomDock.Name == "X" then
			newBoat:SetPrimaryPartCFrame(CFrame.new(randomDock.CFrame.Position.X + 43, newBoat.PrimaryPart.CFrame.Position.Y, randomDock.CFrame.Position.Z) * CFrame.Angles(0, math.rad(90), 0))
		elseif randomDock.Name == "Z" then
			newBoat:SetPrimaryPartCFrame(CFrame.new(randomDock.CFrame.Position.X, newBoat.PrimaryPart.CFrame.Position.Y, randomDock.CFrame.Position.Z + 43))
		end
		
		wait(1)
		plr.Character.HumanoidRootPart.CFrame = CFrame.new(newBoat.PrimaryPart.CFrame.Position.X,newBoat.PrimaryPart.CFrame.Position.Y + 10, newBoat.PrimaryPart.CFrame.Position.Z)
		
		boat_tweens[newBoat.Name] = TS:Create(newBoat.PrimaryPart, TInfo, {

		elseif randomDock.Name == "Z" then
			newBoat:SetPrimaryPartCFrame(CFrame.new(randomDock.CFrame.Position.X, newBoat.PrimaryPart.CFrame.Position.Y, randomDock.CFrame.Position.Z + 43))
		end

	local boat = findBoat(plr)
	if action == "Left" then

	elseif action == "Right" then
		boat.PrimaryPart.CFrame = boat.PrimaryPart.CFrame * CFrame.Angles(0, math.rad(-90), 0)
	elseif action == "Backward" then
		boat.PrimaryPart.CFrame = boat.PrimaryPart.CFrame * CFrame.Angles(0, math.rad(180), 0)
	else
		print(action.." is not left, right, forward or baackward")
	end
		
end)

newBoatEvent.OnServerEvent:Connect(function(plr, boatName, price)
	local stat = plr:WaitForChild("leaderstats").Cash
	if stat.Value >= price then

end)

submergeEvent.OnServerEvent:Connect(function(plr, submerge)
	local boat = findBoat(plr)
		if boat.Name == "Submarine" then
		if not submerge then
			boat:SetPrimaryPartCFrame(CFrame.new(boat.PrimaryPart.CFrame.Position.X, 4.5, boat.PrimaryPart.CFrame.Position.Z))

		elseif submerge then
			boat:SetPrimaryPartCFrame(CFrame.new(boat.PrimaryPart.CFrame.Position.X, -5.5, boat.PrimaryPart.CFrame.Position.Z))
		end
	end
end)

I thought of a way to fix it, and I came up with this:

thing.CFrame.lookVector

so the tween would be

boat_tweens[boat.Name] = TS:Create(boat.PrimaryPart, TInfo, {
	CFrame = CFrame.new(boat.PrimaryPart.CFrame.Position + Vector3.new(200,0,0)) * CFrame.Angles(boat.PrimaryPart.CFrame.lookVector)
})

but it throws me an error:

Unable to cast Vector3 to float

Please help!

CFrame.Angles takes three float arguments. Not one Vector3 argument.

So should I do

boat.PrimaryPart.CFrame.LookVector.X

or can you not do that? I tried looking at the API but that didn’t help.

Try using this:

CFrame = boat.PrimaryPart.CFrame * CFrame.Angles(0, angle, 0) * CFrame.new(0, 0, 200)

I’m assuming the direction the boat is facing is the primary part’s LookVector. Which is how I got CFrame.new(0, 0, 200).

Well to start I think, but I want the boat to keep moving in the primary part’s LookVector, so the tween would I guess stay the same.

#6

Oh, I thought you wanted the boat to the tween to start and end like for example in a racing car game when it shows your car it opens a garage and the starting point for the car is the garage and the target is where the camera is focusing.

And now I think that it’s the boat continuously going around in circles.

Well in that case, you shouldn’t use a tween. You should, maybe, tie a connection to RunService.Stepped and for everytime the event is fired, update the boat’s CFrame accordingly. Or add some body movers.

Ok I can do the

but using body movers didn’t really work out last time :joy:
