一个用纯AS写的正态曲线画法

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); lineStyle(1, c1, 100); lineTo(50, 20); lineTo(0, 20); endFill(); txt.text = t; } }; //===========画框架=============// display = function (mc, x, y, w, h, txt, corl) { with (mc) { moveTo(x, y); lineStyle(0.5, 0x00000, 100); beginFill(corl, 40); lineTo(x w, y); lineTo(x w, y h); lineTo(x, y h); lineTo(x, y); endFill(); createTextField("name", 300, x 2, y-17, 0, 0); name.autoSize = "left"; name.selectable = false; name.border = true; name.background = true; name.backgroundColor = 0x798DA6; name.textColor = 0xffffff; name.text = txt; } }; //========画坐标轴上刻度及数字==============// dial = function (mc, len, corl, txt, type) { with (mc) { moveTo(0, 0); lineStyle(0.25, corl, 100); if (type) {//type不为0时刻度坚着画,为0时刻度横着画; lineTo(0, len); createTextField("num", 600, -7, len 1, 0, 0); } else { lineTo(len, 0); createTextField("num", 600, len 1, -2, 0, 0); } num.autoSize = true; num.selectable = false; num.text = txt; } }; //========画坐标轴============// coordinate = function (x, y) { _root.moveTo(x-215, y); _root.lineStyle(0.25, 0x00000, 100); _root.lineTo(x 215, y); _root.lineTo(x 185, y 5); _root.moveTo(x 215, y); _root.lineTo(x 185, y-5); _root.moveTo(x, y 20); _root.lineTo(x, y-220); _root.lineTo(x-5, y-190); _root.moveTo(x, y-220); _root.lineTo(x 5, y-190); for (i=0; i<19; i ) { _root.createEmptyMovieClip("l" i, 510 i); if (i<13) { !(i%2) ? dial(_root["l" i], 5, 0xff0000, myNum[i/2], 1) : dial(_root["l" i], 3, 0x000000, "", 1);//刻度隔一个为红色,且有数字 _root["l" i]._x = x-198 33*i; _root["l" i]._y = y; } if (i>12) {//同上 !(i%2) ? dial(_root["l" i], 5, 0xff0000, myNum[i/2-3], 0) : dial(_root["l" i], 3, 0x000000, "", 0); _root["l" i]._x = x; _root["l" i]._y = y-33*(i-12); } } _root.createTextField("Xt", 250, x 220, y-3, 18, 18); _root.createTextField("Yt", 260, x, y-230, 18, 18); Xt.text = myNum; Xt.selectable = false; Yt.text = myNum; Yt.selectable = false; }; inputBoxs = function (x, y) { var alpha = ["u =", "0", "o =", "1"]; for (i=0; i<4; i ) { _root.createTextField("v" i, 800 i, x i*35, y, 30, 16); if (i%2) { _root["v" i].type = "input"; _root["v" i].border = true; _root["v" i].text = alpha[i]; } else { _root["v" i].autoSize = "right"; _root["v" i].selectable = false; _root["v" i].text = alpha[i]; } } }; //======写标题========// headline = function (x, y, txt, dx) { _root.createTextField("title", 900, x, y, 0, 0); title.autoSize = true; title.selectable = false; title.text = txt; mytxf = new TextFormat();//创建一个文本格式对象; mytxf.size = dx;//太小 mytxf.color = 0xff0000;//颜色 mytxf.underline = true;//下划线 title.setTextFormat(mytxf); }; //=====开始画线函数====// startDraw = function () { m = Number(v1.text); n = Number(v3.text);//把v1,v3文本框中的值给m,n; x = -200; _root.createEmptyMovieClip("xian", 300); xian.moveTo(-200, 100); xian._x = 275; xian._y = 193; _root.onEnterFrame = function() { a = -(
