Code.org: U3L06 - U3L07 Review

Randomness makes our programs behave differently each time they are run.

The randomNumber command introduced in Lesson 6 helps to make your program react differently when you "Run" it.

In Game Lab, if you get stuck, try… Help and Tips Tab Code Documentation.

In Game Lab, if you make a big mistake… use version history to go back to the beginning.

You follow the instructions in Code Studio.

The "Key Concept" tab describes how to demonstrate your understanding.

You check out the Help & Tips tab if you need help.

Sprites help us keep track of lots of information in our programs.

When you make a sprite, it comes with properties, which are variables that store the characteristics of a sprite.

Properties describe things like where the sprite is located on the screen, what it looks like, and what color it is.

To create a new sprite, use the create sprite command.

You can assign your sprite a label just like you would a variable.

Just like shapes, sprites need to be drawn to the screen.

You can control a sprite's properties in your program by using 'dot notation.'

Sprites can have many properties.

In Game Lab, to make your creations come to life, you want to add images to your sprites.

All images are created and managed in the animation tab.

To add animation, click the plus sign to open library of images that already built into Game Lab.

Once you've selected an image, it'll be added to your project and shown on the left.

You now have to tell the computer that you want this particular sprite. You will use the setAnimation() block to do this.

In the setAnimation, first, you use the name of your sprite and the name of the image you selected in the animation tab.

You can add images or your own drawings to sprites.
