4. Monster Feelings Introduction


Hey Animators!

Today, you will use functions and vector graphics to animate a monster's feelings.

In your project, you’ll animate your own monster to express different emotions like happy, sad, surprised, and angry.

Animators use different types of graphics.

Two popular graphic types that are used in Scratch are vector and bitmap.

Bitmap images are created with pixels, which are tiny squares of color.

Vector graphics are created using points and curves, so they tend to look nicer in Scratch.

At first glance, a bitmap and vector image may look exactly the same.

After zooming in, you can see the square sides of the bitmap images, whereas the vector image has smooth outlines.

An advantage of using vector graphics over bitmap graphics is that the vector images appear smooth when you make the image bigger.

Vector graphics are also easier to edit and manipulate, because you can edit the points and curves.

In a bitmap graphic, you can only draw or erase.

Today, you will program facial expressions on a monster.

Then, you’ll have the chance to edit and manipulate the vector graphics to personalize your monster.

Here are the monsters you can select for your project.

Each monster is in its own starter project.

Now, it’s your turn.
