What You Will Learn
- Create 8 pairs of cards with matching costumes
- Flip cards by switching between front and back costumes
- Track which two cards are currently face up using variables
- Compare cards and leave matches face up or flip both back down
- Shuffle card positions at the start of each game
Step-by-Step Guide
- 1Create a card sprite with 9 costumes: 1 back design and 8 different front designs.
- 2In on start: create 16 clones, position them in a 4×4 grid, shuffle using a random sort.
- 3Each clone stores its pair number using a variable.
- 4When clicked: switch from back costume to the matching front costume.
- 5Track card1 and card2 variables. First click sets card1. Second sets card2.
- 6Compare: if card1 costume = card2 costume: leave both face up, add 2 to matched.
- 7If no match: wait 1 second then flip both back to back costume.
- 8When matched = 16: show You win! and display the number of attempts.
- 9Track attempts — increment by 1 each time a second card is flipped.
- 10Add a timer to create a time-attack mode.
Extension Challenges
