Simple animation slider - Page 2

B1. THE INITIALISING CODE

The whole code is placed in the first frame of the movie and it is:

this.framecounter.onEnterFrame = function() {
	this.theframe.text = _root._currentframe;
};

It is just a line that tells the framecounter clip to write the current frame of the movie.

this.onLoad = function() {
	_global.played = "played";
	_global.togle = false;
	_global.origX = this.slide._x;
	_global.origY = this.slide._y;
	_global.draged = "no";
	_global.factor = 150;
	_global.percentage = factor/_root._totalframes;
	this.lineclip._width = factor+this.slide._width;
	this.lineclip._x = origX;
	this.lineclip._y = origY+this.lineclip._height/4;
};

The initialiser. I've used the following global variables:
played: It declares if the movie is stoped or not.
togle: It is used for the button to swap between the play and the stop state.
origX: It stores the original x coordinate of the slider.
origY: It stores the original y coordinate of the slider.
draged: It declares if the slider is draged or not.
factor: It is actually the desired width of the lineclip and the movement area of the slider. You decide its value.
percentage: Stores the proportion between the width of the lineclip and the total frames of the movie. Very useful.
With the last 3 lines:
I gave lineclip its width. I added the width of the slider for aesthetic reasons.
I told lineclip to go exactly at the original X coordinate of the slider.
The same for Y coordinate. I aligned it with the slider by adding 1/4 of its height to the Y coordinate, also for aesthetic reasons.

Let's continue with the code.
