Module 7: Shooting game Concepts

Lesson 14: Haunted House Game
Objective: Teach students how to create a Haunted House game using motion, sensing, and looks blocks in Scratch. Introduce the concept of shooting and bullets in games.
Introduction:

• Introduce the “Haunted House” game concept: Players use a magic wand to shoot balls at flying ghosts to defeat them.

1. Motion – Turn and Point in Direction:

• Explain the motion blocks for controlling sprite direction.
• Teach how to use “turn … degrees” and “point in direction” blocks.

2. Sensing – Key Pressed:

• Introduce the “key … pressed” block for detecting keyboard input.
• Explain how to use it to control game actions.

3. Looks – Next Costume:

• Discuss costume changes for sprite animation.
• Teach using the “next costume” block to create animation effects.

4. Concept of Shooting and Bullets:

• Introduce the concept of shooting in games.
• Discuss how to create bullets to shoot at moving targets.

Scratch Commands Covered:

• Motion – Turn and Point in Direction: Using motion blocks to control sprite direction.

• End the game and display a win message.

Conclusion:

• Recap the concepts learned: motion, sensing, looks blocks, and shooting mechanics.
• Encourage students to experiment with sprite animation and bullet behavior.
• Discuss the importance of refining gameplay and balance.

Assessment:

• Assess understanding through questions during the lesson.
• Evaluate student projects based on the functioning Haunted House game.
