1
00:00:00,271 --> 00:00:05,071
The last thing I want us to do
is add some code to our project.

2
00:00:05,543 --> 00:00:10,120
If you go near a chest, it will open,
but nothing comes out of it.

3
00:00:10,329 --> 00:00:14,520
It's not spawning an item
for the player to loot.

4
00:00:14,757 --> 00:00:16,214
And we want to remedy that.

5
00:00:16,879 --> 00:00:21,600
To do so we're going to search
for the chest in our project.

6
00:00:22,129 --> 00:00:26,920
And we have a Chest.tscn in Scene
that we could open by double-clicking.

7
00:00:27,329 --> 00:00:30,480
And this has a script attached to it.

8
00:00:30,714 --> 00:00:36,520
The icon there tells you that
you have some code attached to a node,

9
00:00:36,814 --> 00:00:40,600
so you can click the icon to open
the corresponding script.

10
00:00:40,729 --> 00:00:42,070
Don't worry about the code.

11
00:00:42,071 --> 00:00:45,360
You'll learn about what
everything means in due time.

12
00:00:45,629 --> 00:00:48,488
For now, we're just going to
write a line of code

13
00:00:48,489 --> 00:00:50,986
and see how it changes our game behavior.

14
00:00:51,271 --> 00:00:54,080
You have these lines, func loot.

15
00:00:54,371 --> 00:00:57,500
This is a function named loot.

16
00:00:57,643 --> 00:01:02,480
It's code the game executes when
you pass in front of the chest.

17
00:01:02,971 --> 00:01:06,543
And in that function,
after the second line,

18
00:01:06,729 --> 00:01:08,429
_animation_player.play("loot"),

19
00:01:08,629 --> 00:01:11,800
we need to create a pickup for the player.

20
00:01:12,157 --> 00:01:16,071
So you're going to place your cursor
at the end of the line by clicking

21
00:01:16,357 --> 00:01:19,656
and then press enter to create a new line

22
00:01:19,657 --> 00:01:22,470
with this leading tab here.

23
00:01:22,471 --> 00:01:23,760
It's very important.

24
00:01:24,471 --> 00:01:28,771
You then want to call the function
called create pickup.

25
00:01:29,300 --> 00:01:34,185
To do so, you type its name,
starting with underscore create,

26
00:01:34,186 --> 00:01:37,557
and you will get this suggestion
from the engine,

27
00:01:37,800 --> 00:01:40,200
which you can accept by pressing enter,

28
00:01:40,414 --> 00:01:43,871
and it will automatically
complete the line for you.

29
00:01:44,629 --> 00:01:49,857
With that, you can press F5 to play
the game and walk your character.

30
00:01:49,971 --> 00:01:54,210
And as you pass in front of the chest,
it will create a random pickup.

31
00:01:55,043 --> 00:01:58,400
With that, you saw how to assemble a game.

32
00:01:58,401 --> 00:02:00,756
There are a couple things
that we could improve.

33
00:02:00,757 --> 00:02:05,400
For example, in our game right now,
we are missing some invisible walls.

34
00:02:05,543 --> 00:02:09,532
If you want to add them,
you select the invisible walls

35
00:02:09,533 --> 00:02:12,057
in your main scene tab there,

36
00:02:12,371 --> 00:02:16,712
and you click and drag on the cells
where you want the walls,

37
00:02:16,713 --> 00:02:19,000
and you right-click
and drag to remove them.

38
00:02:19,343 --> 00:02:22,505
Note that some walls exist
in the room scenes,

39
00:02:22,506 --> 00:02:25,071
which is why you cannot
erase them this way.

40
00:02:25,357 --> 00:02:30,214
You can just use this
InvisibleWalls node

41
00:02:30,757 --> 00:02:35,528
to create new walls that don't exist
in the other scenes like so

42
00:02:35,529 --> 00:02:39,829
and that will prevent the player
from walking in the sky.

43
00:02:40,129 --> 00:02:44,271
Now, this is where this little
introduction project ends.

44
00:02:44,443 --> 00:02:46,856
You will learn
to create this game,

45
00:02:46,857 --> 00:02:50,956
however, to do so, we need
to first take a step back,

46
00:02:50,957 --> 00:02:55,732
learn the basics of programming
and create much smaller projects

47
00:02:55,733 --> 00:02:58,957
and create all those parts
that you saw here,

48
00:02:58,958 --> 00:03:01,142
like the player, the weapon, the chest,

49
00:03:01,143 --> 00:03:04,680
we'll learn to code those
as separate chunks.

50
00:03:04,971 --> 00:03:08,586
And you will then get to
put your twist on them

51
00:03:08,587 --> 00:03:11,900
and assemble them
into a game that you'll make,

52
00:03:12,114 --> 00:03:15,160
I hope, your own
by the end of the course.

53
00:03:15,671 --> 00:03:19,799
With that, in the next part,
we'll talk about the learn GDScript app,

54
00:03:19,800 --> 00:03:22,657
a free and open-source
application that will teach you

55
00:03:22,658 --> 00:03:27,114
the basics of scripting with
the GDScript programming language.

56
00:03:27,229 --> 00:03:28,392
See you there.
