音樂展 – load()

1. 建立影片元件，並命名音樂影片 / 內容自行設計
2. 建立5個按鈕元件，並分別命名play , stop , up , down , countine。
3. 按鈕內容自行設計
4. 回到場景 , 建立四個圖層，並改名為影片、按鈕、文字、指令
5. 選取圖層：影片 / 按Ctrl + L / 拖曳影片元件至場景中
6. 選取圖層：按鈕 / 按Ctrl + L / 拖曳5個按鈕元件至場景中
7. 分別命實體名稱：play_bt , stop_bt , up_bt , down_bt , countine_bt
8. 選取圖層：文字 / 增加2個動態文字欄位 / 分別命名 : position_txt , soundLength_txt
9. 選取指令圖層的第1影格 / 按 F9 鍵：動作視窗
輸入以下內容
