Position `nil` after moving 19 times

Help and Feedback Scripting Support
#1 
local speed = 1
local car = game.Workspace.Car

-- Check if the Car object exists and has a PrimaryPart
if car and car.PrimaryPart then
	while true do
		car:MoveTo(car.PrimaryPart.Position + Vector3.new(speed, 0, 0))
		print("Moved car model to:", car.PrimaryPart.Position)
		wait(0.1)
	end
else
	warn("Car object or PrimaryPart not found.")
end

The first 19 times it moves, it is fine.
After the part moves 19 times, it gives me the error

Workspace.Car.Script:7: attempt to index nil with 'Position'  -  Server - Script:7

Any idea how to fix?

Is your car being deleted? Do you have streaming content enabled?

#3

it would tell me Car object or PrimaryPart not found. if the car is getting deleted, and it doesn’t

#4

this error message means that you can’t get the position from the variable(car/primary part) because it is nil.

Variable.Position -- If you get that error message from this line then Variable is nil
-- attempt to index nil with 'Position'
#5

No the warning should never run, you have a while true do before it with no break; if it ever enters that while loop it will never run any more code in the same thread.

#6

You have to nest the if statement in the loop in order for it to update each time you try to move the car:

local speed = 1
local car = game.Workspace.Car

-- Check if the Car object exists and has a PrimaryPart
while true do
	if car and car.PrimaryPart then
		car:MoveTo(car.PrimaryPart.Position + Vector3.new(speed, 0, 0))
		print("Moved car model to:", car.PrimaryPart.Position)
		wait(0.1)
	else
		warn("Car object or PrimaryPart not found.")
	end
end

I found out the issue, I made the primaryPart unanchored so it slowly fell out the map, so I had to anchor it and move the if statement, and it works! Thanks though
