So let's just go ahead and get a look at what this final product is gonna look like Esso on like an X pi x cred.

So, whatever you want it to be, you have little snake moving around.

to 不定詞

There's a snack is what I want to call it that shows up, and as you collect it, it increases the length of the tail.

And then, obviously, if you run into yourself and I just did that by clicking the back, you always going forward.

Years as you ran into your tale of your length was nine dot, dot, dot Whatever, um and then you can continue and play as long as you want.

Anyways, what I'm gonna be doing in here is gonna be coating everything object orientated.

I know that there's a much faster and easier way to do this is really teach you that much.

This way, you're gonna learn a bit about objects.

But class is how we can kind of work with, um and you'll see like how the flow of my program goes.

And you should learn quite a bit, especially if you're someone a beginner programmer.

What we're gonna be using to make this is module called Pi Game.

If you don't know the pie game and you want to learn about it, before you do this, I would recommend that.

All right, so let's start coating so pretty much.

What I've done is I've just set up the flow, the program, all the classes and the function just to remind myself what I need to write.

And while I'm talking here, it's really good ideas.

If you guys copy this down, so we're gonna have is gonna have to main objects will have a cube object and a snake object.

And our snake object is going to contain cube objects if that makes sense.

So each one of those little red squares it was moving around is a cube object in the whole thing is our snake object.

Draw grid, redraw window, random snack, message box and main.

So let's get started with our main function here, and this is what's gonna be our main loop.

So essentially, what I need for the main Luke to start is we need to make a service on high game to do this.

We do When he was a game got display, but sent underscoring mode.

We're doing with the height to be with and heights like this.

And I'm going to make a very well pickled with e equals height equals.

And we'll just set this to 500 by but have 500 like, So now we need another variable.

And justice as Rose can delete this down here is gonna do something.

Whatever you consider us, Whatever you want.

Otherwise, you're gonna have, like, weird looking Rose, if you know what I mean.

But if you want to make it harder, said it to something like 10 on and there won't be much room for the snake to move around.

Next, Where we need to do is we just set up a snake object, so I know that we haven't even created, like anything in the snake classy up.

I'm going to s snake, and I'm just gonna give it a position.

So in this case, we want to color say, just gonna be red because red, green, blue to 5500.

We're just start in the middle of something to start at 10.

So I was gonna say, Wow, flag create my variable here.

And then we're just gonna start by doing a pie game.

Uh, I want to say, like, 500.5 or 50 milliseconds every time so that our program doesn't run too fast.

Must look, it's gonna create this clocked on Tick.

And I'm going to use them to create a clock object up here on this is a built in thing in a game.

And what this is gonna do is I explain in just one second.

So what this clock toe don't tick is actually going to do is gonna make sure that our game doesn't run more than 10 frames per second.

So that would mean essentially that are snake would be able to move, like, 10 blocks in one second.

And again, we don't want it to be that fast.

So that's why we're else of delaying by a few milliseconds here if you put this too low.

This is kind of what I found was the best speed in a May.

Very depending on what machine it shouldn't.

So you might want to just change these numbers again.

And the lower this one goes is the slower it's gonna be.

So they're kind of inversely proportional like that.

Next what we're gonna do here, I'm just gonna call redraw Window.

And I bet you that so bad redraw window like so I'm just gonna give it a service, which is in this case is gonna be win that we've created up here.

And for now, that's all I'm gonna put in my main loop here, and we'll move more into that once I start coating some other stuff.

Okay, so now that we have our redraw window being called here, I'm gonna go and I'm gonna start coding our redraw window.

So what this is essentially gonna do Because we first need to update the display supply game display dogs update like so.

We're gonna cost about same surface that we were given.

So when God fill in this case, I'm just gonna use black 000 And there we are.

That's already need to do right now, But essentially, we're also gonna need to draw this snake.

Uh, we're gonna need to draw a few other things on the screen that we'll we'll get to later.

Okay, So drug raid, let's move into this one.

Now, what we need to do here is like draw a grid, which is pretty easy to do.

So what we do is we were given rose and surface, so it's probably a good idea if I actually passed in the rose and surface.

So I'm just gonna global them here so that I can reference them.

I think this is gonna work with the global rose and with, like that.
