[Flashcoders] Could this be done more elegant.

[Jiri]

Hello,

I wrote a routine that checks if the fps is below 45 fps for longer then 
20 ticks, I toggle the quality of the SWF. If it then after is greater 
then 45 fps for 20 ticks I toggle quality back up.

It works, but out of interested, I was wondering if this could be done 
in a other more cleaver way then I did. Looking at the routine it feels 
very 'big', because I use 3 external vars and quite some code.

var treshold:Number = 20;
var buffer:Number = treshold;
var addValue:int;
function doProfiling(e:Event):void{
        if(fps>=45){
                addValue = 1
        }else{
                addValue = -1
        }
        buffer+=addValue
        if(buffer > treshold) {
                buffer = treshold;
        }else if(buffer < -treshold) {
                buffer = -treshold;
        }else if(buffer == 0) adjustQuality()
}

Cheers,

Jiri
