"array count(array())" and "array count(x)" seem to do the same thing. The documentation uses "ARRAY COUNT(Array Name(0))".

Is it necessary to use "x" in "array count(x)" at all?

No. Just do "array count(array())"

...and remember it's not actually the count. It's the highest element number, but arrays start at 0. So if array count() is 10, you have 11 elements.

Why would this be useful to call on anything larger than a one-dimensional array?

take this code for example



p.s. I'm not 100% sure that works, but I am 100% sure an elder could tell you this.

No, that doesn't work, and it's not useful for multi-dimensional arrays. If it's needed and you can justify it, I could put something like this into a plugin.

I have some code here that works without it but it's more complicated than I would like. Every time I add new elements to a string array I have to +1 to another integer array so that I know how many strings there are for when I spit them out.

I wouldn't mind having a function to find the the number of elements in a multi-dimensional array. But I can't justify why I couldn't live without it other than, "it would be really nice".

Well, it's fairly easy to do I guess and the array plugin needs to be updated for new ideas I've had (Ooh, suspense!), so I'll add this in too. Keep an eye on the utility plugin pack, as I'll be adding it there.

You can use a simple for/next loop to look for the last element that has information.

Better support for dynamic multi-dimensional arrays would be great, IanM.

Ok, just let me know what you mean by 'Better support for ...' and I'll consider it.

I just found this and it would appear to be a very useful solution for a problem I've been having with array sizes:
http://forum.thegamecreators.com/?m=forum_view&t=38435&b=1

I can use global variables to keep track of how many elements are in each dimension of the aray and use var=var+1/-1, dim array(var1,var2), to resize them as needed.

A simpler method of changing the dimensions of multi-dimensional arrays by 1 without re-diming them would be nice, like a command to add to/remove from stack/queue for arrays larger than one dimension.

Well, the new ARRAY COUNT function I've written would help.

This would add an extra row and column to an existing array:


It's a bit verbose, so I'm open to any suggestions.
