第一節

計畫如何完成期中作品以及今日目標，以及組員互相討論。
今日目標:在今天這3小時的任務，任務一:產生球根球之間的碰撞。
                                                           任務二:按球的瞬間，球產生分裂時，讓球不會重疊。
                                                           任務三:球點到一定小的時候，產生新的一顆大球。
                                                           任務四:點球時可以算分數。
