Let's say I have an array like so:



I have since populated the array with a bunch of stuff, now I would like to clear it out. As if I had just created the array.
Would something like so work?:



Or do I have to loop through the entire array?:

This should do it, although I haven't tested:

Array[0].length = -1
Array[0].length = 99

Now I am just confused. As far as I knew arrays didn't use index 0 (zero), they started at 1.

If they start at 0, how does this code work then?



I would think it would throw an error every time i try to put something into index 2 (only 0 and 1 are valid indexes). Does AppGameKit automatically resize the array?

AGK starts at 0 and ends with whatever you have declared.

MyArray[2] has 0, 1, and 2.

I see that makes sense.

Print(TestArray.length) seems to give the size of the first dimension. How would i get the size of the other dimensions?



I tried it with the [#] but it always gives me "3"

I think I get it now.

Array.length -> dimension 1
Array[0].length -> dimension 2
Array[0,0].length -> dimension 3
etc.

Wow that is ugly. I am guessing there is some reason to it, backwards compatibility perhaps?
