Everybody.

And welcome to a highlight 2018 tutorial.

Siri's in this video.

We're gonna be introducing you to the highlight competition as well as writing a very, very simple bought.

So if you're not familiar with how light, basically it's just a competition where it's like you versus one or you versus three other players in a sort of environment and the ideas who can write the best.

Aye, aye.

And by I I mean anything from rule based II to ML or Deep learning bots in general, at least historically, the last two, the winners don't know.

Sure about the 1st 1 I'm pretty sure the winners in the first Hala as well we're rule based.

But I might actually be running that I can't remember anyways.

But how light to definitely rule based one.

Um, so anyways, um, what we're gonna be doing here is just making, like, a really basic body.

But first, I just want to talk briefly about the rules, or like how it's done.

So this, at least this is like a visual ization of, um, you know, I get a single game frame, but basically you've got a bunch of frames, and then you start off with just a shipyard.

Like this green thing here is the Green Player shipyard.

You can create some ships, the's like turtles or your ships, and then you run around and try to collect this Hal I TTE and from you know, each ship could hold up to 1000 how light goes to the the drop off, which is either a unique drop off location or, in this case, the shipyard.

You can also drop off at, um and then you just kind of repeat that process.

You build more ships, you can get more.

How light you could build more drop offs.

But ships cost and drop offs cost and so on, so it gets fairly dynamic.

But most of this task boils down to micro and padding.

It's all about the path.

So, um, anyways, I I think that's enough for us to just kind of jump in and run through some information.

Now, just a case I forget to mention.

And at the end, there is plenty of let's see here, learn documentation here.

You'll also maybe go to downloads and download the python version for your operating system.

so, Yeah, the python three version for let's say, Windows 64 boom.

You might want to grab that and look through.

Um, otherwise, I'm just gonna go ahead and jump in.

Also, one more thing.

The AP, I documentation.

So, uh, this just contains information about your game, various commands that you have at your disposal and so on.

But if you do download the highlight three, I do want to just point it now, Where did I put it?

Still may be in down.

Yeah, So you could open up my bought.

Most of what we're gonna run through here is gonna be very similar.

At least most bought starting off are going to look pretty identical.

They're gonna have all the same kind of start information.

Ah, but you can also go into H l t, which is kind of the a p I.

So to speak for python, and you can get more information about what's available to you keep going to open with, uh, on my main computer.

I have sublime.

That's what I use anyways.

And you can kind of see here what various attributes are.

You can make drop off.

And like all that stuff.

It's probably just a good idea to go through here and read these, but I'm not gonna do that together with you guys.

I think you can do that on your own time.

So now let's go ahead and run through some code.

So I'm gonna hit this play here, and then go to the editor If you want to develop locally, you can, um, in probably in one of the future ones.

We will.

Definitely.

If we do the, uh, get to, like, ml on deep learning bots, we'll definitely need to do local development, cause we'll have toe training stuff locally, get a model, then we need to be able to upload that model.

And at least right now, or at least last time I looked to see V two wasn't included, so we'd have to do some other fancy stuff to get that working.

But for now, we can click on the editor.

Uh, we will go with Python three.

Let's see what we start with here.

Okay, so we start with basically, um Let's see if I can zoom in it all without destroying everything.

Good enough.

Okay.

Um, So this is just that that package that I was just showing you.

If you download it locally, you can see there are various constant values.

Things like your How much does a ship cost and so on?

Ah, you can download er not down there, but you can get the directional, uh, basically just the directions from hlt dot position ALS.

So any ship can move either up, down left, right.

And these air referred to as north, South, West, east.

Um, so that's those and random.

I think that's just to pick a random movement in a moment.

Logging.

This is your best friend right now, because basically, the entire game is gonna happen.

You've got multiple players playing against each other and many ships.

Everything's kind of happening all at the same time.

So later on, when things don't go well, you're gonna wanna have been using logging.

Kind of like you might use, you know, print statements.

Our print functions in your actual code.

Now it's gonna be a little harder to use prints.

So and so we're going to use logging and save it to a log file.

And then when the game's over, we can go into that log file and make sure things were happening the way we intended.

So here the game is initialized, and then you send in your, um, whatever name you want for your bought.

Now, at this point, it's important to note that the two second per turn timer starts so you have 2000 milliseconds per turn to make all of your your movements.

So again, with like a deep learning by, it might take longer than two seconds to load in your model, so you would want to have loaded in a model prior to game dot ready.

You might also grab some certain initial game state variables, make some calculations or whatever, and maybe for whatever reason, those take longer than two seconds.

You would want to do that before you said game dot ready.

So here there's just a simple example of a logging logging string and then begins the game loop.

This is just a simple while.

True loop.

This updates every frame.

You're gonna have this every single time.

This gives you some basic data about the game.

What's going on?

This has some basic data about the game map itself.

A little bit later, we'll get a little more deeper into into how that works and stuff.

But for now, simple stuff.

Command HQ.

You basically here As you generate through your ships, you can only, you know, send your command Q one time.

So first you take your command.

Qu build, you fill it with all your commands.

Like if you got five ships, each of those five ships could have a certain command that it's going to do.

So we send each of those ships, you know, one command per ship into the command.

Q.

Now, here is basically they're just asking Hey, um, if the ship positions So where is the ship?

So if we check the game map so the ship position is gonna be a coordinate if that ship positions.

So if those coordinates on the game map and then we can check at those coordinates, what's the hal?

I'd amount if that Hal I'd amount is less than the Max Hallett, which is 1000 divided by 10.

Or if the ship is full, meaning the ship has 1000.

Hal, I TTE, we want to move that ship now.

If that's not true, then we want that ship to go ahead and just eight.

Still continue collecting, Hal.

I'd So, um, so this pretty basic logic.

Now, if we want that ship to move at the moment, it's just gonna randomly move, and it's just gonna move, you know, north, south, east, her west Just simply randomly.

No, no riel logic associated with it.

It's just kind of move.

Um, then we come down here if if you're in the 1st 200 turns and you have enough How Light Spanish ship Don't spawn a ship if you have a ship at port because the ships will collide.

Now, if two ships collide, they both sink to the bottom of the ocean, and their Hallett is just kind of released s so you would want to go when two ships collide, chances are there's a big pile of how light there.

So you want to go collect it, But you'd rather your chips don't collide.

So, um okay, so with that, let's go ahead.

And we could just run this real quick.

Possibly my zoom might have screwed some things up.

Was right.

You have my eyes and messed it up.

Uh, so when we run it Ah, here is the replay.

Basically, you're just playing yourself in this little replay, and then you can also click down here and move up to 10 X just so you can kind of see how things went.

Now you can see up here.

Green has, um somehow 5 62 I'm not quite sure how that could have occurred.

We must have accidentally, uh, gone over the depot and deposited some just by chance.

You can also see year two of our ships definitely collided there.

Okay, so this is just some, like, super super basic, and it's just gonna be by chance whether or not one of these ships actually goes and deposited deposits somehow light.

Now, when you are ready, Um, if you've built everything in here, you can just go in hit submit, and that's totally fine.

Um, and you'll basically start playing, but you'll probably want to do something a little more complex than this before you submit.

So in the next tutorial we're gonna talk about is, you know, doing things like intentionally making drop offs and maybe moving around slightly more logically.

So anyways, if you have any questions, comments, concerns, whatever, up to this point.

Feel free to leave them below.

Otherwise, I'm gonna see you guys in the next tutorial where hopefully we do a little better than we have here till next time.
