Lesson 14: Chase Game with Events


In this online activity, students will have the opportunity to learn how to use events in Play Lab and to apply all the coding skills they've learned to create an animated game. It's time to get creative and make a game in Play Lab!


Here, students will further develop their understanding of events using Play Lab. Students will use events to make characters move around the screen, make noises, and change backgrounds based on user input. At the end of the puzzle sequence, students will be presented with the opportunity to share their projects.

Students will be able to:

  • Create an animated, interactive game using sequence and event-handlers.
  • Identify actions that correlate to input events.



Heads Up! Please make a copy of any documents you plan to share with students.

  • Event - An action that causes something to happen.

Warm Up (10 min)


Briefly discuss the Flappy Bird game from the last lesson. Ask students to come up with the various events in the game. Events include:

  • Flappy hitting the ground
  • Flappy hitting an obstacle
  • A player clicking the screen
  • Flappy passing an obstacle

Now discuss the actions that correspond to these events. Flappy running into something ends the game, but Flappy passing an obstacle wins a point. A player clicking makes Flappy flap his wings.

Ask the students what other events and actions they'd like to see. What other kinds of games could be built around those events and actions?

Lesson Tip

Students will have the opportunity to share their final product with a link. This is a great opportunity to show your school community the great things your students are doing. Collect all of the links and keep them on your class website for all to see!

Remind the students to only share their work with their close friends or family. For more information watch or show the class Pause and Think Online - Video.

This is the most free-form online activity of the course. At the final stage students have the freedom to create a game of their own. You may want to provide structured guidelines around what kind of game to make, particularly for students who are overwhelmed by too many options.

Wrap Up (15 min)


Having students write about what they learned, why it’s useful, and how they feel about it can help solidify any knowledge they obtained today and build a review sheet for them to look to in the future.

Journal Prompts:

  • What was today's lesson about?
  • How did you feel about today's lesson?
  • What is an event your program used today?
  • Is there an event that would you like to have used in your game that you did not get to use in Play Lab?

Extended Learning

Use these activities to enhance student learning. They can be used as outside of class activities or other enrichment.

Look Under the Hood

When you share a link to your story, you also share all of the code that goes behind it. This is a great way for students to learn from each other.

  • Post links to completed stories online.
    • Make a story of your own to share as well!
  • When students load up a link, have them click the "How it Works" button to see the code behind the story.
  • Discuss as a group the different ways your classmates coded their stories.
    • What surprised you?
    • What would you like to try?
  • Choose someone else's story and click Remix to build on it. (Don't worry, the original story will be safe.)
