This is CS 50 on Twitch.

My name is Cole Tanaka and I'm joined today by David Malin and Veronica.

Nothing both stars from prior streams of ours is making sure that everything is framed.

Well, we have a lot of people in the chat today.

We have a super awesome street.

That's super now, right?

That's the last one was super.

This one is super in the sense that it's still gonna be a miss.

This is gonna be a legend.

There's gonna be a legendary legendary I screwed I screwed that one up.

But yet today, as we will be able to see on the stream, Colton will be right back.

He's off camera at the moment.

Second is the legend of Zelda, and I don't think we can actually see super.

Well, if you press A doesn't bring it back, start.

I love this game 20 years.

Okay.

Lena's winning with zero points.

I feel like we should bring it back.

We should bring it back to the title screen here.

So this is the legends over.

You need to play ledges.

All the growing up right?

I did.

This was maybe one of the second on any s game that it played.

Recall.

The Super Mario Brothers came out, and I think a 1985 Zelda was 1986.

So we're kind of working our way annually through my childhood here in like, another iconic Nintendo classic to this day that continue obviously produced really good, like breath with wild being a recent Zelda game.

Did you continue sort of bi annually tri annually releasing a new classic till the Thailand You are an expert on the 1986 version of Zola in the eighties, I was just a cool 20 year old playing video games all the time.

It's just it's really right up my alley.

Well, you've aged well from the you know, I'm just getting I've never played before, so that's good.

We have sort of new and old playing this game and what's interesting, I think about Zelda is that where Super Mario Brothers was a two dimensional side scrolling where you did have a map, but it was only left to right.

Zelda allows you go up down, left to right, and even unto the Z axis, if you will underground as well.

You left and right.

I got that.

This is about as simple as it gets.

This was the original Nintendo controller.

Up, down, left right, B A start.

Select.

No, this is very few buttons.

My computer.

Just have access to the chat.

Second stop.

Maybe going frame.

As so, what we're gonna do is try to go through as much of the game as we can along the way.

Talking about game development, Colton Recall teaches a class on it X called a direction to game development.

Using Lou and a lot of games from yesteryear.

This one among you will try to make a little educational, but it's also near the holidays too.

So we figured we could slip in one more playful stream before the end of the year.

Indeed.

And this is a good one.

Um, and you know, I'd be nice to make Maybe is a little piece at one of these days.

Thing is kids today well, they know what the new versions of Zelda are like.

That's true.

That's true.

But we have an astronomical number of chat messages that we've made.

We should catch up.

Quite a few people actually tuned in live right now.

to, um let me just give a shout out to all the people cause I don't have time to read all the messages to be nice to start diving in.

But all the people that have tuned in So Bella cares Babak night wander through three as Lee.

I did see Brenda was there in the chat.

I believe Brenda was actually the second person to post a message.

Brenda.

Um, she said that she wanted her her daughter to watch us because the dog is a big Zelda fans.

Somebody great music Gold once is.

Hey, Veronica.

Hi.

Tux man is dangerous to go alone.

Take this stress ball.

You know the reference?

No, it's good.

Danger area.

We'll see in just a second.

Okay, let's make a brand new, uh, weaken B CS 50.

It's less true.

We doing well, it zero We greeted that in advance.

So, Athena, Athena, you're about to get bested.

So this is the beginning of the of the game world you kind of liked.

And she gave me a motive sort of when I show you how to play.

It was inspired by exploring his own countryside, and that was a big part of what inspired the way that he designed this game.

And for example, this cave here he would explore caves as a child and go in and sort of looked for them and be mystified by him.

And that's sort of the whole Just did not think this.

This is Link.

No, this is Linkin Link.

I believe it's trying to rescue Zell.

Princess l Direct.

Very.

In the clutches of the evil Gannon is he tells, I did not know in 1986 story of rescuing some but notice I mean, this is Link.

He looks beautiful now in three D graphics on the switch and other hardware.

But, like, look, he's probably like 100 pixels.

Total top down with your much fewer than 100 fewer.

Oh, you mean Oh, yeah, yeah.

I mean, it's a big color presumably.

Is that a Bible?

No, that's a shield.

It looks like a Bible, but you can go up, down, left, right.

His little ears wait and is holding a sword in his left hand?

Not yet, not yet.

He's always not in the store.

Get no.

What's he holding?

That's this year.

His health.

That's his ear to go into this cave.

I don't know.

This is fixed.

This black square represents a k.

Okay, so let's go up here way.

Thing we just read it Dangerous to go alone.

Take this stress ball with somebody said in the chat.

Now, what's gonna happen if I touch the fire?

Is that bad?

I'm not sure I can.

Look, It looks like it's not hurting you.

So this kind of reminds me of scratch.

Like if the link is a sprite, how is it in a game detecting the fire and not letting me go further cause I'm hitting up still?

Yeah, in this case, how would this work in this case?

Both things that was called the bounding box.

Just invisible rectangle that surrounds your character surrounds a knob circle.

Okay.

And by a simple calculation, where you basically see whether the opposing edges of those rectangles are separated, Okay.

Determine whether something is colliding with another box or not called access.

A lot lined, bounding bucks.

So it looks like a big rectangle.

It's not just the fire, because I can't even go up over here.

In this case, what they probably have done is they just said you can't go above why level x o interesting.

So that is pretty much like scratch.

You can express this blocks.

All right.

Should we get the sword.

We could probably do this inscribes.

That's reminds me of a couple.

We have a few students have done these sort of.

What would you call?

This is not a side stroller.

No, this is a, um it's actually adventure game.

It would be It would be a scrolling action adventure.

Tough down, actually.

Adventure.

That's a mouthful.

Strolling top down.

Actually, adventure, I'm not sure what they have a defined.

It is rolling.

As opposed to what?

Um, as a well, in this case, a game.

Maybe that's on one screen that doesn't candy crush for kids.

Your itch?

Yeah.

Multiple scenes means that risk rolling is we're sort of going to different.

Read those map changes over time where it's candy crush and space invaders.

And people want my day.

Yeah, it's just a rectangular region Are gonna get the sword.

Here we go.

Nebula purple is Professor.

Hello, Nabila.

No, uh, I killed Was there?

No, He disappeared because I took the what up?

And maybe fix?

No, we got it.

And now if you look on a So now I can shoot apparent.

I don't remember why this is the case, but Apparently, my sword throws infinite numbers of sore.

Yeah, it's like, I guess, a magical.

So the masters of magical.

So the master sword is the sort of the classic Zelda sword.

Like you get the master sword, usually by pulling it out of a stone like Arthur King.

But in this game, you actually start with the sword that has that ability.

But in the games that followed, you would only get disability once you specific got the master sword.

That was just a magical.

But now we got a pretty early.

So what's interesting about game design?

We talked about this in Super Mario brothers.

Even if you don't really know how to play like that, Black box is clearly alluring in a sort of self instructed me to take a couple of minutes, right.

You can go up left or right.

But more interesting is that black hole so they might be inclined to go in there.

Or maybe maybe it backfires.

Maybe you don't want to go in because it looks like a whole Yeah.

Looks like it.

If you keep going, which way you wanna go?

Okay, let's go.

So the left to the left So now here's your side stroller.

But now, Okay, these scare me.

So I'm gonna shoot with a They're like Spider now.

Heart looks like notice.

I think if I get this hard, it's not gonna do anything cause I already have three in my life for now.

This I don't know why he's allowed to go anywhere now.

I vaguely remember that sometimes the Bushes could be moved or something.

Is that true?

I don't know the exact ones that can be moved, but there is something I have, ah, characteristic to them.

Use an item.

A specific item.

I think I actually haven't beaten this one.

I beat the one for Super Nintendo, but this is one only be 20 years.

30 years, 30 years.

2027.

Question.

Will this be sort of like a static situation or if I restarted the game with So what you're describing is procedural generation of like the game world.

And in this case, no, this is all completely static.

Were random ization again.

Let's see what happens if I come back.

Yeah, everything.

So there are also maintain state.

It maintains safer.

The enemy's Yes.

When you're on the over which way you wanna go?
