Lesson 15 Timers

In this lesson, students will learn how to use timer and operator code blocks to create fun cannonball launching games! Students will also customize a cannon firing game with exploding objects!

New Code Blocks

Objectives

• Use timer and operator code blocks
• Create cannonball launching games that use a charging cannon
• Use code blocks to customize a cannon firing game

Think Abouts:

What does the

• static code block do?
• active code block do?
• start physics block do?
• stop physics block do?
• apply impulse block do?
• when actor collides block do?
• set gravity to block do?
• set shape to block do?

Lessons:

1. Introduction (Video)

• Students will watch an example of a cannon game.

• A friendly alien introduces two coding concepts:
• Timer- Timers are used to keep track of time.
• Operators- Students will watch different examples of operators. The alien points out that operators can be used for arithmetic operations such as add, subtract, multiply, and divide. Operators such as "or" can be used in game loops when checking for two or more conditions.

• Students will play a completed cannon game where they will need to hold the mouse down (web) or hold their finger down (mobile) to charge the cannon. The longer the cannon charges, the further the cannonball will travel. They’ll create their own version of this game in the next module!

• In this DIY (do-it-yourself) project, students will program a cannonball game that charges a cannon using a timer.
• Explain to students that the speed of the cannonball is set using the timer, so holding down the mouse (web) or the touch location (mobile) for a longer period of time will make the cannonball fly farther.

• To solve this puzzle module, students will need to add the code to set the impulse for the cannonball.
• Give a hint: Ask students, “Which three code blocks are needed to program the impulse with a timer?” (Answer: The “apply impulse,” “multiplication operator,” and “timer” code blocks are needed.)

• Students will answer 5 multiple-choice questions to review concepts from this lesson.

• Students will play a completed Cannon Crasher game. They’ll create their own version of this project in the next module!
• Check that students are charging the cannon by holding down the mouse (web) or touch location (mobile).

• In this DIY project, students will customize a cannon firing game with exploding objects!
• The project is complete, so students will need to improve the game by modifying the code and adding customizations.
