Tooooo many froggies

I put together a stock ticker for pixelacres.com (new site I’ve taken a liking to so i’ve been contributing what I can) & it works exactly the way I planned. Here’s the catch, I forgot all about cpu usage while I was making it :-/

As it is now it loads xml & creates a textfield for each childNode in the xml , then onEnterFrame “leapfrogs” (hence this title) all of theese textfields making for a rather boggy experience with 30+ childNodes on a 500mhz (don’t laugh) cpu.

I’ve tried switching it around so it has 4 tapes full of ticks (code will explain that) & leapfrogging theese 4 tapes instead of umpteen kajillion textfields, but so far it’s been a headscratching experience.

Rather than getting fustrated I figured I’d pop this up in here for suggestions/ideas & set the project on the back burner for the day.

Here’s what the XML looks like, // h=“newestRate.PreviousRate”

 
<exch>
<stk nme="supermans super stuff" h="123.432"/>
<stk nme="mikey mikarudens moon cheese" h="456.543"/>

Here’s the movie, (other than a textfield for the time, & 4 speed buttons this is it) (oh yeah there’s a 1 _alpha button over where the ticker shows up that pauses the stream onRollOver)

 
// Variables
spds = [spd1,spd2,spd3,spd4];
_global.tickSpeed = gTSpd();
_global.tapeArry = [];
_global.up = new TextFormat();with(up){color = '0x008800';font='Tahoma';size=12;}
_global.dwn = new TextFormat();with(dwn){color = '0xff0000';font='Tahoma';size=12;}

return R;
}

sol.data.spd = s;
sol.flush();

I won’t cry if noone has any ideas, & I’m sure I’ll figure it out sooner or later, but hey, what good is being a member if you don’t participate :stuck_out_tongue:
