actionscript _currentframe from within a symbol

[peterworth]

hi, i'm trying to use the current frame to determine what to do when an event occurs in a symbol, but _currentframe seems to always be 1 when the event gets triggered, no matter where in the animation we actually are. i guess this is because the script for the event handler is in frame 1 of the symbol's timeline. is there any way around this?

in this script:

this.onRollOut = function()
{
trace(_currentframe);
if (this._currentframe < 40)
{
gotoAndPlay("_out");
}
trace(_currentframe);
}

the first trace is always 1 (wrong) and the second trace is always 40 (right).

The best practice is to place your code in the main timeline, not in the symbol instance timeline:

//Main timeline
yourSymbolInstance.onRollOut = function() {
	trace(_currentframe);
};

If you want to place your code in the instance timeline, you'll need to do it like this:

//Your instance timeline
this.onRollOut = function() {
	trace(_parent._currentframe);
};

ah ok, i can see it would be good practice to keep things in the parent timeline, but that still doesnt solve the issue, because the information i need is the current frame of the symbol animation, not of the root timeline.

now i've got this in the main timeline:

BtnPageOne_mc.onRollOut = function()
{
trace(BtnPageOne_mc._currentframe);
if (BtnPageOne_mc._currentframe < 40)
{
BtnPageOne_mc.gotoAndPlay("_out");
}
trace(BtnPageOne_mc._currentframe);
}

and the first trace is still always coming out as 1, even if the anamination is midway through.

Sorry, I thought you wanted to get the main timeline's current frame!

BtnPageOne_mc.onRollOut = function() {
	trace(this._currentframe);
};

If your trace is 1, then the current frame is indeed 1. You can verify that with Debugger (Control > Debug Movie).

my_mc.onEnterFrame = function(){
trace(my_mc._currentframe);
};

thanks, i'm now using onEnterFrame to update a variable every frame, so that i can use this variable in other event handlers to check which frame the animation is in. not sure if this is the right way to do it though?
