非线性几率

原创代码 | 2009-05-10 16:13

var a;
var 红几率 = 1/3;
var 黄几率 = 1/6;
var 蓝几率;
for (var i=1; i<=100; i++) {
  var ran=Math.random();
  if (ran<红几率) {
    a="红";
  } else if (ran>=红几率&&ran<黄几率+红几率) {
    a="黄";
  } else {
    a="蓝";
  }
  trace(a);

as3完全屏蔽并检测鼠标右键的方法(中文)

原创代码 | 2009-03-02 14:59

虽然17曾经建议我不要研究这种逆天的东西,但是这个东西的诱惑很大,所以还是研究了一下,在网上似乎有英文版的,但是语焉不详,而且很多人懒得看英文,所以自己写了一下,经ie,遨游,firefox测试有效,其他浏览器还请各位自行测试:
index.fla:
import flash.text.TextField;
var _txt:TextField=new TextField;
_txt.text="请用右键点我"
addChild(_txt);
var i=0;
function displayMessage() {
  i++;
  _txt.text=i+"";
}
ExternalInterface.addCallback("showMessage", displayMessage);

        e.preventCapture();
      }
      if (e.preventBubble) {
        e.preventBubble();
      }
    }

  if (event.button != 1&&event.button != 4) {

    thisMovie("index").showMessage();
    //屏蔽弹出
    thisMovie("index").openRightClick();

细心的人还会发现ie里鼠标点快了会有检测丢失的情况,又一遗憾,不过总归可以稍微利用下了吧

爬山代码

原创代码 | 2009-02-19 13:50

man_mc.moveTo(0, 0);
man_mc.lineTo(-20, -80);
man_mc.lineTo(20, -80);
man_mc.endFill();
man_mc._x = 200;
this.createEmptyMovieClip("action_mc", _root.getNextHighestDepth());
action_mc._y = 500;
//山的初始位置
var fillColor = 0x9999FF;
//山的颜色
var totalWidth = 1500;

for (var i = 0; i<=Math.floor(totalWidth/rate+1); i++) {

  action_mc.moveTo(0, (y_arr[0]+y_arr[1])/2+dy/2);
  for (var i = 1; i<=y_arr.length-1; i += 1) {
    action_mc.curveTo(i*rate-rate/2, y_arr[i]-i*dy+dy, i*rate, (y_arr[i]+y_arr[i+1])/2-i*dy+dy/2);
  }
  action_mc.lineTo((y_arr.length-1)*rate, 400);
  action_mc.lineTo(0, 400);
  action_mc.endFill();
};
drawPic();
_root.onEnterFrame = function() {
  action_mc._x -= rate/timeRate;
  action_mc._y += dy/timeRate;
  timeCount++;
  if (timeCount%timeRate == 0) {
    y_arr.shift();
    y_arr.push(action_mc._ymouse/scaley);
    if (timeCount%(timeRate*2) == 0) {
    }
    action_mc._x = x0;
    action_mc._y = y0;
  }
  drawPic();
  var manSpeed = rate/(timeRate*2);
  var manDx = _root._xmouse-man_mc._x;
  if (Math.abs(manDx)>manSpeed) {
    man_mc._x += (manDx>0) ? manSpeed : (-manSpeed);
  }
  man_mc._y = getY(man_mc._x);
};
var getY = function (x):Number {
  var bb:BitmapData = new BitmapData(action_mc._width, Stage.height, true, 0);
  bb.draw(action_mc, new Matrix(1, 0, 0, 1, action_mc._x, action_mc._y));
  var y = 0;
  while (bb.getPixel(x, y) == !fillColor) {
    y++;
  }
  bb.dispose();
  return (y);
};
不知道有没有更高效的方法,欢迎拍砖,测试:

跟随鼠标转动

原创代码 | 2008-05-06 13:02

l_mc.onEnterFrame = function() {
  dx = _xmouse-l_mc._x;
  dy = _ymouse-l_mc._y;
  if (dy<0) {
    l_mc._rotation = 180*Math.atan(-dx/dy)/Math.PI;
  } else if(dy>0){
    l_mc._rotation = 180*Math.atan(-dx/dy)/Math.PI+180;
  }else{
    l_mc._rotation = dx < 0?-90:90;
  }
};

as3 写法:
function getAngle(dx:Number, dy:Number):Number {
  var _angle:Number
  if (dy<0) {
    _angle = 180*Math.atan(-dx/dy)/Math.PI;
  } else if(dy>0){
    _angle = 180*Math.atan(-dx/dy)/Math.PI+180;
  }else{
    _angle =dx < 0?90:90;
  }
  return _angle;
}

汽车代码

原创代码 | 2007-12-14 17:24

今天无聊写的汽车引擎：
新建个实例名叫car_mc的影片剪辑，然后把下面代码贴在桢上就可以了：
var v0 = -5;
var decay = 0.95;
var vx = 0;
var vy = 0;
var angle = 0;
var changeAngle = 0;
_root.onEnterFrame = function() {
  v0 *= decay;
  changeAngle = 0;
  if (Key.isDown(Key.LEFT)) {
    changeAngle = -v0;
  }
  if (Key.isDown(Key.RIGHT)) {
    changeAngle = v0;
  }
  if (Key.isDown(Key.UP)) {
    v0 -= 1;
  }
  angle += changeAngle;
  vx = v0*Math.sin(angle*Math.PI/180);
  vy = v0*Math.cos(angle*Math.PI/180);
  car_mc._x += vx;
  car_mc._y += vy;
  car_mc._rotation = -angle;
};
