How to get the number of objects in an array?

Help and Feedback Scripting Support
#1

I’m making a saveable array to be a representation of a model and I need to convert between the 2 types of data. To do that, I’m making a function that does just that, but one of the things I need to do is get the number of objects in the array and the dev hub doesn’t say how (unless I overlooked it).

You can simply say #Array

#INSERT_ARRAY_HERE (30 characters long)

That’s for dictionaries and mixed tables. Explicit arrays can just be counted using # operator.

It seems that you’re trying to do some serialization.

Here is more if you’re interested.

I just gone into the developer hub, and it said this:

Iterating Over Arrays

Arrays can be iterated over (looped through) in two ways:

  • Use the built-in ipairs() function in a for loop.
  • Get the array’s length using the # operator and loop from 1 to that length value.

That can be simply achieved by like other have said
print(#ArrayName)

But OP is not asking for iteration over arrays but simply getting the length of an array.

Ok, ok, i just wanted to say that it was possible to do that.

#12

Ok im making the script now it’s going well so far.

I’m very late but table.getn() returns the number of elements in an array

It’s also scheduled to be deprecated.
