🏅 Badge Tasks

🥈 Silver Badge

Find or make an image to represent a drink for your pet. PetThirst should increase gradually and then be reset to 0 when the drink sprite is clicked. If it reaches 100, the pet should die.

🥇 Gold Badge

Find or make an image to represent a bed for your pet. PetTiredness should increase gradually and then be reset to 0 when the bed sprite is clicked. If it reaches 100 the pet should die.

🥉 Platinum Badge

PetHappiness should start at 100 and gradually decrease until it hits 0, at which point the pet should die. If the pet sprite is clicked (representing stroking the pet), then it’s happiness should be reset to 100.

Upload a screenshot of your code for each task; named "silver", "gold" and "platinum", to today's assignment on Teams.
