📟⚙️ 7. Sensors: Making a reaction game

🎮 Create reaction test game:

• 🕹️ Moveable light moves left to right.
• 🅰️ Press A button when lights in middle for point.
• ❌ Press at wrong time to lose.
• 🎨 Create ‘sprite’ variable:
• 🌟 Sprite: moveable item, like ‘Steve’ in Minecraft.
• 📊 Set sprite variable:
• 🔄 Initialize sprite as 0.
• 🎮 Use ‘game’ menu:
• 🟢 Find ‘create sprite’ command.
• 📌 Place at coordinates x=2, y=2.

🔢 Each light on Microbit has unique coordinates.

🔍 Light circled is 3,2 (x=3, y=2).

🎯 Can you determine the value of the center light?

• 📍 2,2 because x = 2 and y = 2.
• 💻 Create command…

• 🎨 Create sprite at centre of screen.
• 🏃‍♂️ Make sprite move side to side.
• 🔄 If sprite reaches screen edge, bounce back.
• ⏸️ Add pause to slow down sprite movement.

• 🎮 Adjust sprite speed based on number size.
• 🎮 Set actions for button A press and game win/loss.
• 🟣 Get “on button A pressed” from input menu.
• 🔵 Get “if true then ____________ else_______” from logic menu.
• 🎮 Determine conditions for scoring and game over.
• 🔵 Use “if 0 = 0” from logic menu.
• 🎮 Replace 0 with “sprite x” and 2.
• 🎮 Define actions based on sprite position.
• 🟣 Add “change score by 1” under “if sprite x = 2”.
• 🎮 Add “game over” under “else”.

 The final code will look like this.

• 📥 Download the game and try it out!
• 🔄 Press A and B together to restart after losing.
• ⏩ Adjust speed: Smaller number in pause command for faster pace.
• ⏪ Adjust speed: Larger number in pause command for slower pace.
