Actionscript 3 导航问题

我正在开发一个应用程序，我有一个导航问题。 我在舞台上有随机按钮，但不可避免地会有一些重叠。 我想解决这个问题，但我不知道如何解决。 有人有办法帮我吗

for（var i:int=0；i以下代码已经过测试，并且可以正常工作

var items:Array = [];

var numItems:Number = 16;

for(var i:int; i < numItems; i++) {
    var mc:Mc = new mc_square();
    mc.buttonMode = true;
    addChild(mc);

    while(!freezone(mc)) {
        mc.x = Math.random() * 200;
        mc.y = Math.random() * 300;     
    }
    items.push(mc);
}

function freezone(mc:MovieClip):Boolean {
    var hit:Boolean = false;
    items.forEach(function(item:MovieClip, i:int, a:Array):void {
        if(mc.hitTestObject(item)) {
            hit = true;
        }
    });
    return !hit;
}

简单的点击测试是一个简单的解决方案，但是如果有许多按钮，并且这些按钮的空间有限，则可能会遇到问题。根据情况，更好（更复杂）的解决方案可能是光栅化空间，并在（几乎）每个单元格中随机移动一个按钮：

// environment variables
const numButtons:int = 16;
const maxButtonWidth:int = DummyButton.MAX_WIDTH;
const maxButtonHeight:int = DummyButton.MAX_HEIGHT;
const width:Number = stage.stageWidth;
const height:Number = stage.stageHeight;
// pseudo-random positioning
// ratio is needed for a proportional grid
var areaRatio:Number = width / height;
var maxButtonRatio:Number = maxButtonWidth / maxButtonHeight;
// compute buttons per column and row (take aspect ratios into account)
var cols:int = Math.floor(Math.sqrt(numButtons) * (areaRatio / maxButtonRatio));
var rows:int = Math.ceil(numButtons / cols);
// available space for each button within a grid segment
var spaceX:Number = (width - maxButtonWidth * cols) / cols;
var spaceY:Number = (height - maxButtonHeight * rows) / rows;
// throw an error if buttons won't fit (based on maximum dimensions)
if (cols < 1 || rows < 1 || spaceX < 0 || spaceY < 0) {
    throw new Error("buttons do not fit into area");
}
// for every button
for (var i:int = 0; i < numButtons; i++) {
    var row:int = Math.floor(i / cols);
    var col:int = i % cols;
    var button:Sprite = new DummyButton();
    // coordinate = grid segment + random shift
    button.x = col * (maxButtonWidth + spaceX) + Math.random() * spaceX;
    button.y = row * (maxButtonHeight + spaceY) + Math.random() * spaceY;
    stage.addChild(button);
}

//环境变量
常数numButtons:int=16；
const maxButtonWidth:int=DummyButton.MAX_WIDTH；
常量maxButtonHeight:int=DummyButton.MAX\u高度；
常数宽度：编号=stage.stageWidth；
常数高度：数字=阶段高度；
//伪随机定位
//比例网格需要比率
变量面积比：数量=宽度/高度；
var maxButtonRatio:Number=maxButtonWidth/maxButtonHeight；
//计算每列和每行的按钮（考虑纵横比）
var cols:int=数学地板（数学sqrt（numButtons）*（面积比/maxButtonRatio））；
变量行：int=Math.ceil（numButtons/cols）；
//网格段内每个按钮的可用空间
var spaceX:Number=（宽度-maxButtonWidth*cols）/cols；
变量spaceY:Number=（高度-maxButtonHeight*行）/行；
//如果按钮不合适，则抛出错误（基于最大尺寸）
if（cols<1 | | rows<1 | | spaceX<0 | | spaceY<0）{
抛出新错误（“按钮不适合区域”）；
}
//每个按钮
for（变量i:int=0；i

// environment variables
const numButtons:int = 16;
const maxButtonWidth:int = DummyButton.MAX_WIDTH;
const maxButtonHeight:int = DummyButton.MAX_HEIGHT;
const width:Number = stage.stageWidth;
const height:Number = stage.stageHeight;
// pseudo-random positioning
// ratio is needed for a proportional grid
var areaRatio:Number = width / height;
var maxButtonRatio:Number = maxButtonWidth / maxButtonHeight;
// compute buttons per column and row (take aspect ratios into account)
var cols:int = Math.floor(Math.sqrt(numButtons) * (areaRatio / maxButtonRatio));
var rows:int = Math.ceil(numButtons / cols);
// available space for each button within a grid segment
var spaceX:Number = (width - maxButtonWidth * cols) / cols;
var spaceY:Number = (height - maxButtonHeight * rows) / rows;
// throw an error if buttons won't fit (based on maximum dimensions)
if (cols < 1 || rows < 1 || spaceX < 0 || spaceY < 0) {
    throw new Error("buttons do not fit into area");
}
// for every button
for (var i:int = 0; i < numButtons; i++) {

    var col:int = i % cols;

    stage.addChild(button);
