Effective PyCharm Transcripts
Lecture: Moving code
0:00 Let's talk about another cool and powerful.
0:02 Refactoring So what we've done over here in this 'actors.py' f is we
0:07 put every class that's going to be participating in our game.
0:10 So we've got the creature, we've got the wizard,
0:12 we've got the small animal. One of the things I prefer to do in general
0:16 Not always, but in general is to have a class dedicated to its own
0:21 file. So if I want to go mess with the wizard,
0:22 I know right where to go and how to make changes to it and so on
0:26 But what I'm going to do is move this wizard over to its own file
0:30 Now I could go over here and right click new python file,
0:37 call it something like lowercase wizard and then copy this over and that would work except
0:42 remember other parts of our program depend upon this.
0:46 So here we say from actors import wizard.
0:49 If I were to move that code manually over to another file,
0:52 this is going to break. It's going to say there's no wizard and actors because
0:56 it's not, it's somewhere else wherever I put it,
0:58 we're going to not just want to move the file or move the code into a
1:02 file. We also need to fix up things like these imports or if I had
1:06 done something like import actors and then actors dot wizard and work with it in this
1:12 way. Right. We need to make sure that all that stuff is consistent.
1:15 There's this really cool re factoring called move and let's do the main animals first and
1:20 then we'll deal with creature in a moment.
1:22 First of all, let's go and come down here and just hit move and I'm
1:26 gonna call this wizard and down here we now have the wizard class,
1:32 so we're importing the creature that we can derive from it.
1:36 And besides a little white space at the end,
1:38 this looks great importantly over here,
1:42 notice now we have from wizard import wizard and it's gone from up there,
1:46 so it's not just moving the code is actually keeping everything in sync,
1:49 which is fantastic. Let me do the others as well.
1:52 Do the dragon and the small animal.
2:03 So in our game core, all that stuff has been fixed.
2:06 The other thing I would like to do is maybe just call this.
2:09 Well now it's not actors, it's just the creature.
2:11 So I'm gonna just rename this file two creature base when I do that,
2:18 notice it renamed and refactors that as well.
2:21 That's not exactly a move, but it's pretty close,
2:25 make sure everything's running, we can attack something.
2:28 We have been defeated. Let's try again.
2:34 We have handily defeated. A frog I believe.
2:36 Noah toad. Alright, we're out so it looks like it's still working now.
2:41 This is looking cluttered to me.
2:42 I don't know how you all feel about it,
2:44 but let's go back and sort of give this some naming here.
2:47 Like I'm going to create an actor's folder and I want to put all of these
2:51 in there. So we are last move action.
2:54 If we just take all of those and drop them in there,
2:57 notice this is not a move button,
2:59 but this is a refactor button.
3:01 Search for references. Boom. Go back to our game core from actors dot creature
3:07 based actors dot small animal actors dot dragon.
3:09 So now our code is nice and organized.
3:11 Here's the program, here's the game code,
3:14 here's all the animals and there's not a folder and all of those operations,
3:18 renaming a file, extracting code to another file,
3:21 grabbing a bunch of files and throwing them into another folder.
3:24 All of that remained consistent because they're all under this general manner of a move re
3:30 factory in PyCharm. Love it.
