My name is Colton Ogden, and this is CS50 on Twitch.

So today, we are going to be putting together a game that was actually

Hope I'm pronouncing your name correctly.

So last week, we implemented-- well, last week and this week,

Last week we did the first part, where we had the Snake moving around.

Added a bunch of the bells and whistles, and had a great time.

And then early this week, we had a few other streams.

Next week we'll have a few other streams.

But today, we're actually going implementing

what's called concentration or the memory card game,

I've been doing a little bit of research here on potential sprites to use,

but let's take a look at what the memory card game, or as it's called,

And shutouts to Asli, there, in the stream.

Asli Tumerkan, that was a very good pronunciation.

But this is what that game looks like in one of its many incarnations.

It's a game that you can see in a lot of other games, a lot of video games.

And for example, what I think what comes to mind--

I think I saw it in Mario Party a long time ago.

But essentially, it involves a bunch of face

down cards or other surfaces with some sort of picture

or unique iconography on the other side of the card,

and your goal is to match pairs of these cards that are alike,

If you flip over two cards that are the same, they get to remain flipped over.

So you can sort of see what cards that you've successfully matched.

And if you flip over two cards that are unique--

they're both different images or whatnot--

then they get flipped back over, and you sort of

have to remember which cards you flipped over erroneously, such that later on,

if you flip over one card that you happened to also flip over somewhere

else, you can sort of remember where the two were

And hello to Ilyass as well, who spoke in the chat before the stream began.

implement a version of this in Lua and Love2D.

So recall Love2D or Love is the framework

that we used on Friday and Monday of this last week,

and it's a really nice, simple 2D focused

framework that allows us to code in Lua, which is also

a lightweight, fast scripting language used extensively in game programming

Next week, actually though, we'll start taking a look at Unity and C sharp,

which is quite a bit different, but I know

many people are interested in Unity, and I myself am very interested in Unity.

I myself am very interested in Unity and improving my skills there.

So it will fun to do some live coding in that.

So let's go ahead and dive right into the implementation of concentration,

I'll call it concentration just because on Wikipedia,

And if we go to Wikipedia, just so that we can tie it all together,

this is where I initially looked it up to see

And so there's many different iterations.

So we actually can't see it too well, but yeah, you can play it in a circle.

You can play it in a sort of rectangular arrangement.

An important thing to take into consideration

when playing pairs or concentration is that if you have an odd number of cards

laid out, as by maybe having three by three rows of cards on your table

or whatnot, then you're actually going to need some sort of joker

card or some other wild card to fill in that extra slot because the game does

So if it's a not even number of cards, it won't work.

But just by having that wild card and maybe making

that an instant game over, or an instant sort of flip back over,

Today, we're going to focus on having at least one of our axes of our cards

be even so that no matter what, we'll always have an even number of cards

But that would be an interesting way to introduce a new game mechanic.

OK, so anyway, that aside, I'm going to go and make a new folder in--

I have a folder called streams on my hard drive.

This is going to be my Love2D folder in my project folder.

I'm going to drag that into my editor, which is VS Code.

I'm going to open it up, close the window that was behind it,

expand this a bit so that it takes up the whole screen.
