Hi all!
I’m using this timer code for my project but im having a little problem understanding several of the lines. This code was attached to a frame on the main timeline, and a movie clip called my\_mc placed on the stage. Can anyone explain in detail what is happening and why for each of the lines in red? Thanks for any help! Much appreciated.
[COLOR=red]t0 = getTimer();
this.onEnterFrame = function(){
var t1 = getTimer() - t0;
var s1 = Math.round(t1 / 1000);[/COLOR]
var t2 = 60 - s1;
if (t2 \<= 0)
delete this.onEnterFrame;
t2 = 0;
my\_mc.swapDepths(666);
my\_mc.removeMovieClip();
trace(t2);
};

getTimer() starts the timer in t0
gettimer returns the time elapsed since creation of t0…but its in miliseconds
so divide by 1000 = seconds

> t0 = getTimer();
getTimer() function returns number of milliseconds till start of the flash movie
> this.onEnterFrame = function(){
assings to “this” an onEnterFrame… it is following code terminated with “};” on the last line. This function is called on every frame.
> var t1 = getTimer() - t0;
This assings to variable “t1” time since “t0” was declared… it gets higher every frame
> var s1 = Math.round(t1 / 1000);
This assings to “s1” converted value of “t1” from milliseconds to seconds as 1 second = 1000 milliseconds.
Do you need something more or is it clear enough?
