And welcome to a highlight 2018 tutorial.

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.

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.

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.

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

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.

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?

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.

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

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.

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.

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

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.

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

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.

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.

You're gonna have this every single time.

This gives you some basic data about the game.

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.

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

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.

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