Subway surf movement system

[stone loom]

Here is the code :
local UIS = game:GetService("UserInputService")

local camerapart = game.Workspace:WaitForChild("CameraPart")
local speed = -5

local laneWidth = 8
local currentLane = 2

UIS.InputBegan:Connect(function(input, gameProcessed)
if not gameProcessed then
if input.KeyCode == Enum.KeyCode.A then
-- Move left
currentLane = math.max(currentLane - 1, 1)
elseif input.KeyCode == Enum.KeyCode.D then
-- Move right
currentLane = math.min(currentLane + 1, 3)
end
end
end)

game:GetService("RunService").Heartbeat:Connect(function()
local targetPosition = (currentLane - 2) * laneWidth
local currentPosition = camerapart.Position.X
local netvalue = targetPosition - currentPosition
local movement = math.clamp(netvalue, -0.9, 0.9)

camerapart.Position = camerapart.Position + Vector3.new(movement, 0, speed)

end)

the code works fine, but after a certain distance the camera part goes back to its original position for some reason and starts to move again.
The video i provied shows the issue

there was no cut in the video. the part literally went back to its original position

what

[sour lotus]

iirc, subway surf doesn't move the player, it moves the map to the player, which is alot more simple to script imo

[stone loom]

ok, but i am trying to move the part(not the player). the part is controlled by the player

[sour lotus]

It seems to move fine

[stone loom]

in the video u can see it works, but after some distance, the camerapart seems to tp back to starting position

and then moves again

[sour lotus]

Try to remove the math.clamp line

[stone loom]

but that is needed to move the cube or needed to change lanes

[sour lotus]

Ohh

[stone loom]

if the value is +ve, it would clamp to 0.9, so the speed of the cube will go diagonally

[sour lotus]

Does it constantly go back when it reaches that point?

Hmm interesting

[stone loom]

yes

like it goes on a loop. lets say , for example the cube starts at 0,0,0 and moves along -z axis at the speed of -1. so after it reaches to a point (say 0,0,1000), the cube goes back to original position)ie 0,0,0)

[stone loom]

u know what, imma try this logic

** You are now Level 3! **

[stone loom]

nvm it is much harder compared to what i am trying to achieve

What you're trying to achieve will eventually cause the game to lose performance

Roblox's physics and rendering engine won't be able to handle the larger positions as the player gains ever-increasing distance away from the world origin
