How to refer to parts within a model

[abstract ember]

I am making a basic obby so I can learn coding as I'm pretty new to it. I'm trying to make a part where parts alternate between being collidable and not. How do I refer parts inside of the model?

obviously this is wrong because it doesn't work lol

You can use getchildren()

Or something similar if that doesn't work

That will provide you a table of instances that are in the model

You can loop through each instance with that table

[abstract ember]

how would a format that?

game.workspace.alternate1.getchildren()?

[sweet kraken]

ModelName:GetChildren()

[abstract ember]

like this?

Is alternate2 a model?

[sweet kraken]

Sort of yea

[abstract ember]

yes it is

[sweet kraken]

But I would suggest making a variable for the model and a variable for the children you are obtaining

That way you have a table you can loop through

hello!, Is there anyone need help?

[abstract ember]

ya

[abstract ember]

is this functional?

im workin on something else rn

[tender scroll]

Yes, this line is syntactically and functionally correct in Roblox Luau, assuming alternate2 is a valid Instance.

[graceful compass]

casually ignores the orange line where it says alternate2 is nil

[tender scroll]

Oh, alternate2 doesn't exist or hasn't loaded yet when the line runs.

[tender scroll]

replace it with this code :

local alternate2 = workspace:WaitForChild("Alternate2")
local switch = alternate2:GetChildren()**

[abstract ember]

what are the stars for?

and what does wait for child mean?

ik its kinda self explanitory but why do i need to wait for the child?

of that

It helps with runtime errors
