【正文】 單擊某個按鈕時。用戶單擊鼠 標按鈕或按鍵;在滿足特定條件或進程完成( SWF 文件加載、時間軸到達特定的幀、圖形完成下載等)時,系統(tǒng)會觸發(fā)相關事件。了解事件發(fā)生的時間和位置將有助于您確定在什么位置、以什么樣的方式用一個動作響應該事件,以及在各種情況下分別應該使用哪些 ActionScript 工具。 5 鼠標和鍵盤事件 用戶與 SWF 文件或應用程序交互時觸發(fā)鼠標和鍵盤事件??稍趲暇帉懘a或向實例附加腳本,以處理這些事件以及添加所需的所有交互操作。例如,可 以在用戶進入場景時將外部 SWF 文件或 JPG 圖像加載到影片剪輯中,或允許用戶使用移動鼠標的方法在場景中調(diào)整元素的位置。幀事件可用于根據(jù)時間的推移(沿時間軸移動)觸發(fā)動作或與舞臺上當前顯示的元素交互。附加到幀上的腳本稱為幀腳本。這是使用 stop() 函數(shù)實現(xiàn)的。 將 SWF 文件停止在特定的關鍵幀后,您需要執(zhí)行某種動作。 8 組織 ActionScript 代碼 您可以將腳本附加到關鍵幀和對象實例(影片剪輯、按鈕和其它元件)中。另外,這還會導致難于在不同的 Flash 應用程序之間共享代碼。 不要將腳本附加到關鍵幀、影片剪輯和按鈕這些元素中,而應通過調(diào)用一些駐留在一個中心位置的函數(shù)來響應事件。常見的做法是創(chuàng)建一個名為動作 的圖層,并將 ActionScript 代碼放置在該圖層上。如果在其它 Flash 應用程序之間共享代碼對您來說很重 要,請使用 腳本 窗口或您最喜愛的文本編輯器來創(chuàng)建一個外部 ActionScript (AS) 文件。隨著項目的擴展,這種簡便性帶來的好處將超出您的想像。 若要使用外部 AS 文件中包含的 ActionScript 代碼,您可以在 FLA 中創(chuàng)建一個腳本,然后使用 include 語句來訪問存儲在外部的代碼,如下例所示: include “ ../core/” 您還可以使用 ActionScript 來創(chuàng)建自定義類。還可以使用組件(預構建的影片剪輯)共享代碼和功能,例如 UI 元素和腳本。 SWF 文件或應用程序的交互可以散布于項目中的多個元素中,您可能很 想試一試直接將腳本添加給這些元素。您應該轉而通過調(diào)用駐留在一個中心位置的函數(shù)來響應事件。若要創(chuàng)建包含或導入到應用程序中的外部腳本,可以使用“腳本”窗口(選擇“文件”“新建”,再選擇 ActionScript 文件)或您喜愛的文本編輯器。 動作 面板和 腳本 窗口都具有 腳本 窗格(在其中鍵入代碼)和 動作 工具箱。 Flash 在“動作面板中提供這些功能是因為它們在 FLA 文件中編輯 ActionScript 的上下文時特別有用。 teaching efficiency, also can add vivid artistic effect courseware, conduce to the academic knowledge expression and munication. In order to provide students with intuitive experimental process, improve their learning efficiency and flash animation in the teaching application is necessary. This paper to make proteins dialysis animation as an example, introduced simply have strong ability and unique interactive , discusses how to use the make protein dialysis experimental animation whole process and related matters. What is Flash Flash is an authoring tool that lets designers and developers create presentations, applications, and other content that enables user interaction. Flash projects can include simple animations, video content, plex presentations, applications, and everything in between. In general, individual pieces of content made with Flash are called applications, even though they might only be a basic animation. You can make mediarich Flash applications by including pictures, sound, video, and special effects. Flash is extremely well suited to creating content for delivery over the Inter because its files are very small. Flash achieves this through its extensive use of vector graphics. Vector graphics require significantly less memory and storage space than bitmap graphics because they are represented by mathematical formulas instead of large data sets. Bitmap graphics are larger because each individual pixel in the image requires a separate piece of data to represent it. To build an application in Flash, you create graphics with the Flash drawing tools and import additional media elements into your Flash document. Next, you define how and when you want to use each of those elements to create the application you have in mind. When you author content in Flash, you work in a Flash document file. Flash documents have the file extension .fla. A Flash document has four main parts: The Stage is where your graphics, video, buttons, and so on appear during playback. The Timeline is where you tell Flash when you want the graphics and other elements of your project to appear. You also
