MakeCode Microbit 遊戲設計：「接雞蛋」(Microbit Game: Egg Catching)

首先來分析影片中遊戲的功能有哪些：

Game design:

1. 角色「player」（就是玩家你囉），位在最下方的紅點。Player will be at (x, y) = (2, 4) when the game is started.
2. 角色「egg」（從天而降的雞蛋），位於上方不停落下的紅點。Egg will be at (x, y) = (pick random 0 to 4, 0) when the game is started.
3. A按鈕將「player」角色往左移動一格。When the A button is pressed, player moves to the left.
4. B按鈕將「player」角色往右移動一格。When the B button is pressed, player moves to the right.
5. 「player」角色接到「egg」角色時，會有動畫與音效，並得一分。When the player catches the egg, score 1 and perform some animation and play a melody.
6. 雞蛋落到地面三次時，遊戲結束，並顯示Game Over，以及總得分。When the egg fall to the ground three times, the game is over. Show “Game Over” and total score on the screen.
