Help with variables?

Asked 225 views1 answers

I was trying to print the names of the models in my set that I have by using GetUserSets method but I keep getting a error saying: Workspace.Script:8: attempt to index global 'Model' (a nil value) Why is it showing vairble Model as nil?

InsertService = game:GetService("InsertService")
UserSets = InsertService:GetUserSets(1077607)
Set = UserSets[1] -- Think of this like a tablet Set 1 = 1 Set 2 = 2 and so on
SetId= Set.AssetSetId
Collection = InsertService:GetCollection(SetId)
for i = 1,10 do
Model = Collection[i]
AssestId = Model.AssestId
print(AssestId.Name)
end

So, to begin - trust Lua. It is nil. You can see this yourself if you printed Model. You'd also see something useful, something like this:

1203523
10358234
1203481
nil
Workspace.Script:8: attempt to index global 'Model' (a nil value)

The reason is probably that your result, Collection is a list fewer than 10 things in it. But, you ask for all the way up to Collection[i]. Asking for an index which isn't in a table will result in nil.

Instead, go up to the length of the table:

for i = 1, #Collection do

Thanks for the help,but now it won't print any of the names why?

assetId is a number, so assetId.anything doesn't make sense. To get the name, use model.name not assetId.Name

As an addenum, kevinnight, I suggest looking up generic for loops, which are designed for iterating through tables, like you do here.
