Braces vs. Brackets

[cozziekuns]

Probably a dumb question but...

What's the difference between Braces {} and Brackets [] when scripting with RGSS2?

Well, braces create hashes and blocks. Square brackets create arrays. Since square brackets aren't really involved in blocks, I'm guessing what you are asking is what is the difference between a hash and array. There are quite a lot, but I'm guessing what you're interested in is that arrays can associate an object with an ID integer, whereas a hash can associate objects with any arbitrary objects, and there isn't any necessary order to it.

So, for instance, an array could be:

Code Select Expand


array = [5, "abc", 84]


and then array[0] would return 5, array[1] would return "abc", and array[2] would return 84.

Whereas a hash could be:

Code Select Expand


hash = { 1 => 5, "alpha" => "abc", :sym => 84 }


and then hash[1] would return 5, hash["alpha"] would return "abc", and hash[:sym] would return 84.

There are a number of reasons to use one or the other, if you want to know more.

Oh, that makes a bit more sense.

Thanks Modern.

Yeah, he's awesome.

Agreed.
