Re: [問題] 新手上路~
大致的概念就是先把路線函式規劃好
例如以下的路徑
(0, 0)───┐(3, 0)
│
│
(3, 3)
寫成參數式形式(t = 0~1)如下
f(t) = 如果(t == 0~0.5)則內插(0, 0)和(3, 0)
如果(t == 0.5~1)則內插(3, 0)和(3, 3)
至於畫面的表現方面
先產生一堆點，每個點對應的t值都與前後差一個單位(可以是0.1, 0.01, etc.)
用enter frame或timer事件重複執行一個更新函式
而這個更新函式做的事情，就是把每個點的t值累加一點點
並且依照每個點的新t值帶入f(t)得到的新座標來更新點的位置
