1. korak: Napravi

Što je to?

S dva micro:bita zaigraj ovu klasičnu igru i usput saznaj o postupku odabira, varijablama i slučajnim brojevima.

Ova dva videa prikazuju što ćeš napraviti i kojim kodom:

Uvod

Vodič za kodiranje

Kako to radi

  • Igra kamen, papir, škare je klasična igra na sreću za dva igrača. You and a partner shake your fists 3 times and then make gestures at random to show a rock, paper or scissors. Rock beats scissors, scissors beat paper and paper beats rock (it wraps the rock!).
  • When the micro:bit accelerometer detects a shake movement, it sets the variable tool to a random number: 0, 1 or 2.
  • We use 0 because computers start counting at 0, and it’s good to remember that 0 is a number!
  • The program uses selection to decide what image to show on the LED display. If the random number was 0, it shows a rock icon, if it was 1 it shows the icon representing paper. If it wasn’t 0 or 1, it must be 2 because we instructed the micro:bit to only pick random numbers between 0 and 2, so in that case it shows scissors.

Što ti treba

  • 2 micro:bita (ili simulator MakeCodea)
  • Uređivač MakeCode ili Python
  • Komplet baterija (po želji)
  • a partner to play with

2. korak: Kodiraj

3. korak: Unaprijedi

  • Draw your own icons for rock, paper, scissors.
  • Think of other tools that could replace rock, paper and scissors or invent new rules.
  • Use the micro:bit radio function to make a game that knows if you won or lost by communicating with your friend’s micro:bit.
