Calling a function on enter frame frame (HTML5 canvas)

Hi,

I have a newbie question.

I want to define and execute a function and apply that code it to a frame in the timeline.

Previously, I've used the same function on a button click event:

this.button_name.on('click', function ()
{
	var randomframe = Math.floor(Math.random() * _this.movieclip.totalFrames);
	_this.movieclip.gotoAndStop(randomframe);
});

How do I modify the above so that it executes upon entering a frame instead of a click event?

Correct answer kglad

var randomframe = Math.floor(Math.random() * _this.movieclip.totalFrames);
	_this.movieclip.gotoAndStop(randomframe);

will work. but if you really want to execute a function, you can do it more verbosely with:

gotoF();

function gotoF(){

var randomframe = Math.floor(Math.random() * _this.movieclip.totalFrames);
	_this.movieclip.gotoAndStop(randomframe);

}

p.s. if you want to eliminate the need to use:

var _this=this;

you can use:

gotoF.bind(this)();

function gotoF(){

var randomframe = Math.floor(Math.random() * _this.movieclip.totalFrames);
	this.movieclip.gotoAndStop(randomframe);

}
