Detecting Colors (Lesson 5)

Introduction

New Code Blocks

Objectives

• Use code blocks to detect when an Actor is touching a certain color, another Actor, or the edges of the Stage
• Create a sketching game

Warm-Up (15 minutes)

• You will learn how to detect when an Actor is touching a certain color, another Actor, or the edges of the Stage.
• As a class, brainstorm different situations when you would want your Actor to detect another color, another Actor, or the edges of the Stage. For example,
• If you’re creating a maze game, you can program an Actor to return to the beginning of the maze if it touches the maze wall.
• You can program your Actor to react (e.g., grow, shrink, explode) when it touches another Actor.
• You can program your Actor to detect the edges of the Stage and never leave the screen.
  

• A friendly alien introduces two coding concepts:
• Touching Color?- you will watch Codey demonstrate how the “touching color” block checks if an Actor is touching a specific color.
• Touching?- you will watch Codey and the friendly alien demonstrate how the “touching?” block can be applied to different situations.

• you will play a completed Explode on Impact game. You’ll create their own version of this game in the next module!
• How to play: You to use the arrow keys to move the racer. If the racer touches an enemy trail, it’s game over!

• In this DIY (do-it-yourself) project, you will program a racer game where racers explode if You touch other racers’ pen trails!
• Activities include animating explosion and detecting when Actors touch certain colors.

• To solve this puzzle module, you will need to program two enemy racers to explode when You touch the green line.
• Give a hint: Ask you…
• There are 9 costumes for both of the cars SO:
  you need to use the 8x loop to go thru all of the costumes before hiding the enemy cars!
• What coding block should we add to each of the racers’ code so You explode when touching the green line?
• How do we get the racer to look like it exploded?

• you will view a completed Detect Color project. You’ll create their own version of this project in the next module!
• What happens when one car touches the other car’s line.

• In this DIY (do-it-yourself) project, you will program a car sketching game. Both cars will follow the student’s mouse pointer, and the game will restart if either car touches the other, or the other’s trail.
• You will need to program the red car to follow their mouse or finger, leave a pen trail, and start over. The yellow car’s code is already complete.
• How long can your you keep the cars separated?

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

Are you already done???? Extended Activities (10 minutes)

• Challenge: practice the skills you’ve learned in this course by creating a game that uses
  • “change size by”
  • “play sound”
  • “touching?” code blocks.
    
• For example, you could create a game with a garden scene with a bee that lands on flowers. When the bee lands on a specific color or Actor, the bee can make a buzzing sound and grow larger. Bonus: Program other Actors to chase the bee.
