Scratch has two drawing modes- vector and bitmap. Both drawing modes allow you to create artwork, but each serves a different purpose. In this movie, see how to use the bitmap drawing mode, and the key differences between vector art and bitmap art. You will also see some examples of why you might want to choose one drawing mode over the other.

- [Voiceover] Now let's look at using the bitmap tools.…Remember that the difference between…painting a vector graphic and a bitmap graphic…is that vector uses shapes, and a bitmap uses pixels.…To paint a vector or a bitmap graphic…for a sprite or a backdrop…you just simply click the Paint button.…So if we wanna paint a new sprite…we click the button here to paint a new sprite,…and if we wanna paint a new backdrop…we click the button here to paint a new backdrop.…I'm going to click to paint a new sprite.…Let's say we wanna make a happy face.…
I wanna point out that when you're drawing with a bitmap…the tools are on the left side,…and if you look at the bottom right of the Editor here…you're going to see that we're in Bitmap Mode.…But if you wanna change to Vector Mode,…watch where the tools go.…So now we have Vector Mode, and the tools go to the right,…so we do have a different set of tools…on the left and on the right.…So let's go to the left by clicking Convert to Bitmap,…and you may notice that we also have…
He starts with demonstrating how to create your first project and gather the artwork (aka sprites) and other assets you'll need to build it. Todd then reviews the prebuilt scripts, the bits of code that control the logic of your Scratch projects, and explains how to use the different script types for different functions, such as animating sprites, responding to events such as button clicks, and comparing values. In chapter 3, he covers costumes, and in chapter 4, he shows how to load and play sounds. Finally, he shows how to put it all together into a complete web game, which you can then share with the Scratch community.
