All right, it's time to move some existing code and data
0:04
over here, just from our previous persistent
0:06
Rock Paper Scissors.
0:08
Remember, one of the things that we used in the 15-way
0:10
Rock Paper Scissors was we needed this CSV file to
0:14
basically determine who wins and who loses
0:18
for any combination of those 15-way battles.
0:22
Let's paste that over here.
0:24
We're going to have our CSV file that tells us that,
0:27
and we'll also have this DB folder thing,
0:29
we already saw that.
0:30
This just tells us easy way to get back to this location
0:33
base and generate either read or writable files here.
0:36
We're going to put our SQLAlchemy data in there as well.
0:40
That has to do with reading the data in the games.
0:43
The other thing we had was lots of stuff around SQLAlchemy
0:45
defining the models and saving and querying who played
0:50
a game, does the player exist, all of that stuff.
0:52
We're just going to take that and drop it in here.
0:55
We're not really going to change that hardly at all.
0:59
But I'm going to make this folder called game_logic,
1:02
and you can see we have our SQLAlchemy declarative base.
1:05
We have our move.
1:06
This literally is the same thing as before.
1:08
It's not changed at all.
1:09
We have our game decider, our GameService.
1:12
These are all basically the same.
1:14
I had to add just a couple of methods to GameService,
1:16
but they're super trivial, like find a roll by id,
1:18
and things like that.
1:20
Nothing important or new here,
1:24
other than this only change really is that this game,
1:27
it used to have all the loop logic and all that stuff,
1:31
and now we need to really separate that.
1:33
That's going to go down into the client,
1:35
but there's still a little bit of work that our game class
1:37
is going to do.
1:38
We'll have this over here.
1:41
There we've moved in the code from our game previously.
1:44
Now our job is to integrate it into our web application.
