一个用纯AS写的正态曲线画法

【 tulaoshi.com - Flash 】

我的这段AS写了不少有用的函数,如画按钮函数,画坐标轴函数,画框架函数.这些函数都有很强的移植性,以后都可以直接拿来用; //================按钮和坐标轴上的文字=====================//
mytxt = ["开始", "暂停", "清除", "全屏", "退出", "继续"];
myNum = ["-30", "-20", "-10", "0", "10", "20", "30", "X", "Y"];
//=====画按钮(type不为0时按钮为凸起状态type=0时按钮为凹下状态)=====//
CommandButton = function (mc, t, type) {
c = 0xffffff;//按钮左和上边框颜色
c1 = 0x000000;//按钮右和下边框颜色
mc.createTextField("txt", 700, 12, 1, 27, 18);
if (!type) {
c = 0x000000;
c1 = 0xffffff; //type=0时左和上与右和下边框颜色交换;
mc.createTextField("txt", 700, 13, 2, 27, 18);//按下时文本框向左下移,使字有凹下感觉
}
with (mc) {
moveTo(0, 20);
lineStyle(1, c, 100);
beginFill(0xD1DEE9);
lineTo(0, 0);
lineTo(50, 0);

lineTo(50, 20);
lineTo(0, 20);
endFill();
txt.text = t;
}
};
//===========画框架=============//

lineTo(x+w, y);
lineTo(x+w, y+h);
