利用Flash除了可以制作出精彩的动画课件外,还可以用其自带的Actions语句完成简单的编程,满足日常的教学要求。本文即是用Actions基础知识制作的一个用于求解二元一次方程组的求解器。第一步,打开Flash,按下Ctrl+M快捷键,修改文档的大小为500×400,背景为浅蓝色。第二步,单击工具栏中的文字工具,在舞台上绘制一个矩形区域,作为变量的输入区域。并选择该文字区域,打开属性对话框,将该文字区域的类型设置为“输入文本”,输入文字方式定义为“单行”,设置变量为“al”, In addition to using Flash to create wonderful animation courseware, you can also use its own Actions statement to complete simple programming to meet the daily teaching requirements. This article is a solver for solving a binary system of equations using the basic knowledge of Actions. The first step, open Flash, press Ctrl + M shortcut keys, modify the size of the document is 500 × 400, the background is light blue. In the second step, click the text tool in the toolbar to draw a rectangular area on the stage as the input area for the variable. And select the text area, open the properties dialog box, set the type of the text area to “enter text”, enter the text mode is defined as “single line”, set the variable to “al”,
