Welcome to the final stage of this course.

At this point, we've built out most of our classes.

We've created several objects that are all working together and

interacting with each other.

We've rendered our visual components and added interactivity so

a player can move their tokens around the board and drop them into spaces.

But now what?

A turn isn't just dropping a token.

In a real life game,

a lot of the synthesis that happens after someone drops a token is automatic.

We can clearly see a space is filled with a token.

It's obvious whose turn it is, and

a winning move is visible right in front of us.

In our game, though, we have to write the logic for the series of calculations.

So throughout this stage,

you'll be creating new methods to handle these tasks.

At the conclusion of this course, you will write

a final method called update game state, that calls them all in a specific order.

This update game state method is the callback function that was

mentioned earlier in the course.

This function is passed as an argument to the drop animation, and

is called once the animation is complete.

Calling the update games state callback will trigger the following events.

Filling the target space with the active token, checking for a winning move, and

switching the active player.

You'll tackle each of these steps one by one and then together, we'll

come together for a solution video for the completed update game state method.

That will be followed by a final demo of the game.

Good luck, and see you soon.
