lang=EN-US>ActionScript</SPAN><SPAN style="FONT-FAMILY: 幼圆">来说，是最为重要的概念，一切都基于对象，一切都离不开对象。在</SPAN><SPAN lang=EN-US>ActionScript</SPAN><SPAN style="FONT-FAMILY: 幼圆">中，对象分为两类，一类是用户自己制作的动画元件</SPAN><SPAN lang=EN-US>(Symbol)</SPAN><SPAN style="FONT-FAMILY: 幼圆">实例化后而形成的实体对象</SPAN><SPAN lang=EN-US>(Instance Object)</SPAN><SPAN style="FONT-FAMILY: 幼圆">，声明这类对象后，可以在</SPAN><SPAN lang=EN-US>ActionScript</SPAN><SPAN style="FONT-FAMILY: 幼圆">堆砌的属性和动作行为进行控制</SPAN><SPAN lang=EN-US>;</SPAN><SPAN style="FONT-FAMILY: 幼圆">另一类是</SPAN><SPAN lang=EN-US>Flash MX</SPAN><SPAN style="FONT-FAMILY: 幼圆">自己定义的抽象对象</SPAN><SPAN lang=EN-US>(Abstract Object)</SPAN><SPAN style="FONT-FAMILY: 幼圆">，例如</SPAN><SPAN lang=EN-US>Math, Date</SPAN><SPAN style="FONT-FAMILY:

幼圆">允许声明全局变量和局部变量。所谓全局变量，也就是声明一次，在整个动画的</SPAN><SPAN lang=EN-US>ActionScript</SPAN><SPAN style="FONT-FAMILY: 幼圆">程序都可以使用的变量；所谓局部变量，就是在函数中声明，只能在函数中被使用的局部性的变量。</SPAN></P><P class=MsoNormal><SPAN style="FONT-FAMILY: 幼圆">（</SPAN><SPAN lang=EN-US>4</SPAN><SPAN style="FONT-FAMILY: 幼圆">）事件响应。在</SPAN><SPAN lang=EN-US>Flash</SPAN><SPAN style="FONT-FAMILY: 幼圆">动画中，动画的交互性就是通过对用户动作的响应来完成的。在</SPAN><SPAN lang=EN-US>ActionScript</SPAN><SPAN style="FONT-FAMILY: 幼圆">中，用户的事件有鼠标事件、键盘事件等，诸如鼠标的移动、按钮的按下和松开、拖动以及键盘上的按键被按下等都属于用户事件的范畴。</SPAN><SPAN lang=EN-US>ActionScript</SPAN><SPAN style="FONT-FAMILY: 幼圆">可以通过</SPAN><SPAN lang=EN-US>On()</SPAN><SPAN style="FONT-FAMILY: 幼圆">方法来进行响应。</SPAN></P><P class=MsoNormal><SPAN style="FONT-FAMILY: 幼圆">（</SPAN><SPAN lang=EN-US>5</SPAN><SPAN style="FONT-FAMILY: 幼圆">）语句和运算符。</SPAN><SPAN lang=EN-US>Flash MX ActionScript</SPAN><SPAN style="FONT-FAMILY: 幼圆">的语法风格和</SPAN><SPAN lang=EN-US>JavaScript</SPAN><SPAN style="FONT-FAMILY: 幼圆">的非常类似，同样有判断、循环等控制流程的语句，同时还提供了丰富的运算符号。当然多条语句组成的一个常用的功能可以被封装成一个自定义函数。这些都使得</SPAN><SPAN lang=EN-US>ActionScript</SPAN><SPAN style="FONT-FAMILY: 幼圆">更易于使用。</SPAN></P><P class=MsoNormal><SPAN
