Processing 101 – 04 BouncingBallGameV01

BouncingBallGame – version 0.001

A brief testing of bouncing ball game.
Rules: 1. Press the mouse button for initial ball speed.
2. Bounce each bat for getting one point.
3. Try not to hit the red bat, because it will fasten the speed.
4. Press “UP” & “Down” can change your bat size.
5. Tell me your score.

簡單小遊戲

遊戲規則:
1. 按下滑鼠按鈕,調整開始球速。
2. 每彈跳一下,加一分。
3. 嘗試著不要碰到紅色球拍,每碰一下,球會加速。
4. 按下鍵盤“上”“下” 可調整球拍大小。
5. 告訴我您的分數。
