Let's tackle the final stage of Four in a Row - adding in the Game logic.
[MUSIC]
0:00
Welcome to the final stage of this course.
0:04
At this point,
we've built out most of our classes.
0:06
We've created several objects
that are all working together and
0:09
interacting with each other.
0:12
We've rendered our visual components and
added interactivity so
0:14
a player can move their tokens around
the board and drop them into spaces.
0:17
But now what?
0:21
A turn isn't just dropping a token.
0:22
In a real life game,
0:25
a lot of the synthesis that happens after
someone drops a token is automatic.
0:26
We can clearly see a space
is filled with a token.
0:30
It's obvious whose turn it is, and
0:33
a winning move is visible
right in front of us.
0:35
In our game, though, we have to write
the logic for the series of calculations.
0:37
So throughout this stage,
0:42
you'll be creating new methods
to handle these tasks.
0:43
At the conclusion of this course,
you will write
0:46
a final method called update game state,
that calls them all in a specific order.
0:48
This update game state method is
the callback function that was
0:54
mentioned earlier in the course.
0:58
This function is passed as an argument
to the drop animation, and
0:59
is called once the animation is complete.
1:03
Calling the update games state callback
will trigger the following events.
1:05
Filling the target space with the active
token, checking for a winning move, and
1:09
switching the active player.
1:14
You'll tackle each of these steps
one by one and then together, we'll
1:16
come together for a solution video for
the completed update game state method.
1:20
That will be followed by
a final demo of the game.
1:24
Good luck, and see you soon.
