Hi, my question is simple, why this isnt working

workspace.ship.PrimaryPart.Changed:Connect(function ()
print("change")
end)

Hello yet again (lol)
You can use :GetPropertyChangedSignal to connect on a certain property changing, here’s how:

workspace.ship.PrimaryPart:GetPropertyChangedSignal("CFrame"):Connect(function()
    print("The CFrame has changed!")
end)

And why isnt my code working??

#4

There could be multiple reasons why, my only hypothesis is that it’s being fired too many times for it to handle (yes that can happen).

not working…

I tested this in studio and it worked for me, are you certain that there’s a PrimaryPart?

main is a Model, you’ll want to change it to a singular part.

no, main is part (in the same named model)

The event .Changed is fired only when a property of the “selected instance” changed.
It’s not working maybe because your instance (here main) not changing.
You also can’t use the .Changed event with a model for detect when the PrimaryPart change.

So you should just rename the PrimaryPart (and select PrimaryPart not by a property) :

workspace.ship.[Name Of The Part].Changed:Connect(function()
print(“change”)
end)

Make sure that you change model’s position with funciton SetPrimaryPartCFrame. This might be also useful if you are moving model from one distance to the other distance.
I hope this helps. :herb:

Part:GetPropertyChangedSignal()

behaves just like a .Changed event, except you can modify it to connect to a function based on a certain quality of the object changing.

for example

If you insert a script with this code :
–We will suppose you have set a primary part for the whole model
, so then you can detect changes in the property of that specific part.

local part = script.Parent--primary part of the model

       part:GetPropertyChangedSignal("CFrame"):Connect(rotated)
	
	function rotated()
	    print("the position of the part is " .. part.CFrame.Position)
	       end
	
	print(part:GetPropertyChangedSignal(CFrame) == part:GetPropertyChangedSignal(CFrame))

i tried this

workspace.ship.main.mainPart:GetPropertyChangedSignal("CFrame"):Connect()

but nothing

#15

Maybe because nothing change. Try again with a script that change the CFrame

I tried using

workspace.ship.PrimaryPart.CFrame=workspace.ship.PrimaryPart.CFrame+Vector3.new(0,100,0)

but also nothing

#18

I dont know, but you are attempting to add a Vector3 and a CFrame. I vaguely remember that technically being ok, but try this:

workspace.ship.PrimaryPart.CFrame=workspace.ship.PrimaryPart.CFrame+CFrame.new(Vector3.new(0,100,0))

#19

Just, for be sure, try this (I don’t know if it’s working, I am very bad with CFrame) :
workspace.ship.PrimaryPart.CFrame=CFrame.new(Vector3.new(0,100,0))

#20

ok, but anyway, the cframe change (it go 100 up), but the event wont fire

#21

Send a screenshot of what it looks like in the script, with the explorer open, showing where your script is, and screenshot the whole page.

#22

It’s probably that the Changed event and the RBXScriptSignal returned from GetPropertyChangedSignal will not fire if there’s a change in position and cframe

You can use RunService.Stepped:Connect() to check to see if there are changes in its position
