When you’re working on animations in Game Lab, using a lot of variables for each shape can get pretty confusing. Imagine you have to keep track of a shape’s X position, Y position, width, height, and maybe even its color and outline. Now, if you want to animate more shapes, you’ll need even more variables. This can make your code messy and hard to understand.
So, how can you make this easier? The answer is to use sprites! Think of a sprite as a character or object in your animation. At first, a sprite might just look like a simple rectangle, but it has special features that make it really useful.
When you create a sprite, it automatically comes with properties that describe it. These properties include where it is on the screen, what it looks like, and its color. To make a new sprite, you use the createSprite command. You can give your sprite a name, just like you would with a variable. For example, you might create a sprite and call it “mySprite,” but you can choose any name you like.
Just like shapes, sprites need to be drawn on the screen to be visible. You can do this with the drawSprites() command. This command will display your sprite in the area you want.
You can change a sprite’s properties in your program using something called dot notation. This means you connect the sprite’s name to the property you want to change with a dot. For example, if you set mySprite.x to 200, it moves the sprite’s X position to 200. If you set mySprite.width to 50, it changes the sprite’s width to 50. The next time you use drawSprites(), these new values will be used to show the sprite.
Sprites have lots of properties you can explore. As you get to know them, you’ll find you have powerful ways to control how your sprites look and behave. This makes your animations more dynamic and interesting!
Start by creating a simple sprite using the createSprite command. Give it a name and set its initial properties like position and size. Experiment with different values to see how they affect your sprite’s appearance on the screen.
Animate your sprite by changing its properties over time. Use a loop to gradually move your sprite across the screen or change its size. Try to make your sprite move in a pattern, like a circle or zigzag.
Think of a character you want to create using sprites. Design its appearance by setting properties like color and size. Use multiple sprites if needed to add details like eyes or a mouth. Share your character with the class!
Explore different sprite properties by changing them in your code. Try altering properties like rotation or scale and observe the effects. Document your findings and discuss how these properties can enhance animations.
Create a short storyboard using sprites to tell a simple story. Plan out the scenes and use sprite properties to animate the story. Present your storyboard to the class and explain how you used sprites to bring your story to life.

If you want to animate a single shape in Game Lab, managing multiple variables can become challenging. You’ll need variables for the shape’s X position, Y position, width, height, and as you add fills, strokes, and other characteristics, you’ll require even more variables. If you decide to animate additional shapes, you’ll have to create a separate set of variables for each one. This can lead to issues with organization and clarity in your code.
So, what’s a more elegant and manageable way to keep track of these variables? The solution is to start animating with sprites. Think of a sprite as a character that exists within your animations. Initially, a sprite may just appear as a rectangle, but the advantage of a sprite lies in its underlying properties.
When you create a sprite, it comes with properties that store its characteristics. These properties describe aspects such as the sprite’s location on the screen, its appearance, and its color. To create a new sprite, use the create sprite command. You can assign a label to your sprite, similar to how you would with a variable. For instance, this code creates a new sprite and labels it “mySprite,” but you can choose any label you prefer.
Like shapes, sprites need to be drawn on the screen. Use the drawSprites() command to display your sprite in the designated area. You can control a sprite’s properties in your program using dot notation. Connect the sprite’s label to the property label with a dot. This allows you to manipulate it like a variable. For example, setting ‘mySprite.x’ to 200 updates the sprite’s X location to 200, and setting ‘mySprite.width’ to 50 changes the sprite’s width to 50. The next time you call drawSprites(), these updated property values will be used to render the sprite.
Sprites have numerous properties, and as you become familiar with them, they will provide you with powerful controls over your sprites’ appearance and behavior.

Game – A program or application designed for entertainment, often involving challenges or puzzles. – Example sentence: “We used a coding platform to design our own video game in computer class.”
Lab – A place or environment where experiments and practical work are conducted, often involving computers and technology. – Example sentence: “In the computer lab, we learned how to write our first lines of code.”
Sprites – 2D images or animations that are integrated into a larger scene, often used in video games. – Example sentence: “I created several sprites for my game, including a hero and a villain.”
Animation – The process of creating motion and shape change illusions by displaying a sequence of static images that minimally differ from each other. – Example sentence: “We added animation to our project to make the characters move across the screen.”
Properties – Attributes or characteristics of an object in programming, such as size, color, or position. – Example sentence: “By changing the properties of the sprite, I made it larger and changed its color.”
Create – To make something new, such as a program or a digital design, using coding or software tools. – Example sentence: “Our assignment was to create a simple app that could solve math problems.”
Draw – To produce a picture or diagram by making lines and marks, often using a computer program. – Example sentence: “We used a graphics program to draw the background for our game.”
Control – To manage or regulate the behavior of a program or device, often using code. – Example sentence: “I wrote a script to control the movement of the character in the game.”
Variable – A storage location identified by a memory address and a symbolic name, used to hold data that can be changed during program execution. – Example sentence: “We used a variable to keep track of the player’s score in the game.”
Screen – The display area of a computer or device where information, images, and videos are shown. – Example sentence: “The game was designed to fit perfectly on the computer screen.”
