[Flashing Lights with Auto Alpha]

Hi there,

 

I am trying to populate a space with Lights at different sizes, blur amounts and alphas. I think I have acheived this.

 

I want the final effect to be that the lights flash and use the random alpha amounts to do so. I hope this explains what I am after.

Not sure if this is a Greensock question and sorry if it isn't.

 

And i'm not sure if the answer lies in auto alpha, yoyo:true, repeat:-1 ???

 

import com.greensock.TweenMax;
import com.greensock.easing.*;
import com.greensock.plugins.AutoAlphaPlugin;
import flash.filters.BlurFilter;


flashingLights = function () { 


TheWidth = 300; // The Width of effect area -> in pixels
Object(this).bg._width = this.TheWidth


TheHeight = 250; // The height of effect area -> in pixels
Object(this).bg._height = this.TheHeight


maxLightsize = 60; // Scaling the cell
NumOfCells = 70; // Quantity of Cells on the stage


for (i=0; i < NumOfCells; i++) { // by using the 'for' looping sequence
TheCell = attachMovie("Light_Cell", "Light_Cell"+i, i); // attaching the 'Light_Cell' from the library (Linkage)
TheCell._alpha = 10+Math.random()*60; // creating random alpha value
RandomSet = 4*Math.random()*4; // Create a random set for amount of blur
TheBlurEffect = new BlurFilter (RandomSet,RandomSet,3); // Create variable with the filter setting (xBlur, yBlur, quality)
TheCell.filters = [TheBlurEffect] // Applies the filter to the object named myObject
TheCell._x = -(TheWidth/2)+Math.random()*(1.5*TheWidth); // positioning the cell on the X axis.
TheCell._y = -(TheHeight/2)+Math.random()*(1.5*TheHeight); // positioning the cell on the Y axis.
TheCell._xscale = TheCell._yscale = 60 + Math.random()*(maxLightsize*10); // determine the scale of the Cell
}


TweenMax.to(Light_Cell, 1, {_alpha: 10});


};


flashingLights();

 

I should add that all of the 'lights' are being placed on the top layer when I run this going over the top of text.

 

Thanks for you help,

[TweenMax new value on yoyo / repeat]

Hi all,

 

I am relatively new to Greensock and thought I was going well but have hit a small challenge.

I am trying animate the effect of a volume equalizer going up and down.

 

To keep it looking as natural as possible i wanted to vary the heights that the levels rise to.

However, when I run the below code it picks the last number that the function generates and then doesn't 'refresh' a new value when the loop repeats. Is there a way to call randomRange everytime the tween repeats?

 

function randomRange(min:Number, max:Number):Number {
    var randomNum:Number = Math.floor(Math.random() * (max - min + 1)) + min;
    return randomNum;
}
for (var i = 0; i < 1; i++) {
    var n:Number = randomRange(-27, -72) // Audio levels between these 2 numbers.
    trace(n);
}


TweenMax.to(Object(this).main.window1.shade, .2, {_y:n, yoyo:true, repeat:-1, delay:.2});
TweenMax.to(Object(this).main.window2.shade, .2, {_y:n, yoyo:true, repeat:-1, delay:.3});
TweenMax.to(Object(this).main.window3.shade, .2, {_y:n, yoyo:true, repeat:-1, delay:.4});

Thanks for any help that is given,

 

Phil
