我有大量对象(472)需要一个计时器来检查变量状态变化之间需要多长时间。下面的代码是我到目前为止所拥有的,但是运行的许多计时器肯定会影响应用程序的性能,是否有更好的优化方法来衡量这一点?
import flash.utils.Timer;
var active_:Boolean;
var matched:Boolean;
var vacated:Boolean;
var circ:Shape=new Shape();
this.addChild(circ);
circ.x = 0;
circ.y = 0;
var circRad:Number = 5;
var mat= new Matrix();
var busyColors = [0xFFFF00,0xFFCC00];
var idleColors = [0xCCCCCC,0x000000];
var matchedColors = [0x0099FF,0x0066FF];
var vacatedColors = [0xFF0000,0x990000];
var busyAlphas = [1,1];
var idleAlphas = [0.5,0.5];
var ratios = [0,255];
var prev:int = 0;
var time:Timer = new Timer(1000,0);
//time.start();
mat.createGradientBox(2*circRad,2*circRad,0,-circRad,-circRad);
circ.graphics.lineStyle();
if (active_ == false)
{
if (prev != 0)
{
setAverage(prev,false);
prev = 0;
}
circ.graphics.clear();
circ.graphics.beginGradientFill(GradientType.RADIAL,idleColors,idleAlphas,ratios,mat);
circ.graphics.drawCircle(0,0,circRad);
circ.graphics.endFill();
}
else if (active_ == true && matched == true)
{
if (prev != 1)
{
setAverage(prev,true);
prev = 1;
}
circ.graphics.clear();
circ.graphics.beginGradientFill(GradientType.RADIAL,matchedColors,busyAlphas,ratios,mat);
circ.graphics.drawCircle(0,0,circRad);
circ.graphics.endFill();
}
else if (active_ == true && vacated == false && matched == false)
{
if (prev != 2)
{
setAverage(prev,true);
prev = 2;
}
circ.graphics.clear();
circ.graphics.beginGradientFill(GradientType.RADIAL,busyColors,busyAlphas,ratios,mat);
circ.graphics.drawCircle(0,0,circRad);
circ.graphics.endFill();
}
else if (active_ == true && vacated == true)
{
if (prev != 3)
{
setAverage(prev,true);
prev = 3;
}
circ.graphics.clear();
circ.graphics.beginGradientFill(GradientType.RADIAL,vacatedColors,busyAlphas,ratios,mat);
circ.graphics.drawCircle(0,0,circRad);
circ.graphics.endFill();
}
function setAverage(i:int, a:Boolean)
{
time.stop();
switch (i)
{
case 0 :
break;
case 1 :
MovieClip(root).avgMat.push(uint(time.currentCount));
break;
case 2 :
MovieClip(root).avgBusy.push(uint(time.currentCount));
break;
case 3 :
MovieClip(root).avgVac.push(uint(time.currentCount));
break;
}
if(a == true){
//time.reset();
//time.start();
}
}
注释掉由于问题而启动的计时器。
