All right, welcome back. In this chapter, we will learn to invent our own application

00:22.360 --> 00:27.840
that will allow us to draw and paint in scratch. And right now, it's very easy to program

00:27.840 --> 00:33.680
one of these applications for ourselves, and you will learn how to do it in this chapter.

00:33.680 --> 00:38.400
So let me show you how this works. Tip on the green flag. You notice this little pencil

00:38.400 --> 00:42.760
that follows my mouse? This is something that we haven't done before, and we will learn

00:42.760 --> 00:49.120
how to do it. In this chapter, we will learn how to make sprites. Follow our mouse. So this

00:49.120 --> 00:54.280
pencil follows my mouse. And at some point, if I bring my mouse down towards the menu,

00:54.280 --> 00:59.200
hit the buttons below, the pencil will stop following me as you can see. And if I bring

00:59.200 --> 01:04.720
the mouse back up to the open space, the pencil will start following me again. If I click

01:04.720 --> 01:09.240
and start dragging on the screen, notice that the pencil starts drawing on the white space

01:09.240 --> 01:13.960
and by default, the pencil leaves a black mark. But if I click one of these buttons, for

01:13.960 --> 01:18.760
example, the green one, the pencil will change its color and will draw something else.

01:18.760 --> 01:23.840
Now, besides the colors, we have a number of control buttons that we will use to program

01:23.880 --> 01:29.200
this pencil. For example, we have these buttons plus and minus, used to grow and shrink

01:29.200 --> 01:34.400
the mark of the pencil. So, if you want a thinner mark, you need to press the minus button

01:34.400 --> 01:39.440
a couple of times and you see the very thin green mark. Or if you want to grow it, you

01:39.440 --> 01:45.560
need to press the pause button a bunch of times and it will leave a much thinker. Mark.

01:45.560 --> 01:49.360
There's also an option to erase what you've done by clicking this button with the magic

01:49.360 --> 01:54.240
wand. When you click it, notice the cursor changes and you can start dragging around

01:54.240 --> 01:59.480
and deleting what you've done. Now, if you're tired of deleting things yourself, you can

01:59.480 --> 02:04.480
click this zap button with the lightning bolt mark and everything will disappear. If you

02:04.480 --> 02:08.680
want to switch back to drawing, you can always click this pencil button which switches the

02:08.680 --> 02:14.480
mode back to pencil and you can draw in black again. So, we will learn how to create this

02:14.480 --> 02:18.400
very cute application from nothing. Starting in the next video.
