JavaScript code for Animate Color Effects > Advanced settings

Hi Animate support community,

Is there a way to access the Animate Color Effects > Advanced panel settings with JavaScript code?  I have an old project written in ActionScript 2.0 that I am trying to convert to HTML5 Canvas.  This project contains many images of flowers as movie clips and I want to change the color of these flowers from a button click.

 

The base drawing objects of these flowers is done in grayscale gradients and the color is applied using the Color Effects > Advanced panel (see attached JPG) which shows the settings and results.  The code below doesn’t work to change the color because it’s not accessing the Color Effects > Advanced settings.  Is there a way to access these settings with JavaScript?  Thanks.

this.yellow_btn_1.addEventListener("click", change_color_yellow.bind(this));

function change_color_yellow()
{
	bellFrontLt.petals_mc_1.shape.graphics._fill.style = "rgb(255,255,0)";
}

Hi.

 

You need to apply a color filter. Like this:

var colorFilter = new createjs.ColorFilter(1, 1, 1, 1, 46, -14, 255, 0);
var bounds = this.flower.nominalBounds;

this.flower.filters = [ colorFilter ];

// in this case, the registration point of the flower is in the middle, so the initial x
// is half of the width to the left and the initial y is half of the height to the top
this.flower.cache(-bounds.width * 0.5, -bounds.height * 0.5, bounds.width, bounds.height);

 

I hope it helps.

 

Regards

Thanks so much for your help João.  Here's the code I used and it works!  I changed the color of the flower from lavender to yellow.

var colorFilter = new createjs.ColorFilter(1, 1, 1, 1, 255, 255, 0, 0);
var bounds = bellFrontLt.petals_mc_1.nominalBounds;

this.yellow_btn_1.addEventListener("click", change_color_yellow.bind(this));

function change_color_yellow()
{
	alert("yellow button clicked");	
	bellFrontLt.petals_mc_1.x = 300;
	
	bellFrontLt.petals_mc_1.filters = [ colorFilter ];
	bellFrontLt.petals_mc_1.cache(-bounds.width * 0.5, -bounds.height * 0.5, bounds.width, bounds.height);	
}

Hi.

 

Great!

 

You're welcome.

 

Where is bellFrontLt defined? If bellFrontLt is the name of a instance that is placed directly on the timeline where you script is, then you should refer to it using the this keyword: this.bellFrontLt.

 

Please let us know.

 

Regards,

JC

let bellFrontLt = this.bellFrontLt_mc;

Nice.

 

It should be working. I've tested your code and it worked without a problem.

 

Can you provide more details? Some screenshots or your FLA?

Hi JC,

Thanks for getting back to me.  I don't have any problems with the code.  It works perfectly, thanks to you.  Below is the code I used to change two different flowers (one lavender and one pink) to yellow or orange by clicking a yellow or orange button (see JPG).  This is "proof of concept" code.  Eventually I'll use an array and a for loop.  Thanks so much for you help.

let bellFrontLt = this.bellFrontLt_mc; 
let bellSideLt = this.bellSideLt_mc;

var colorFilter_yellow = new createjs.ColorFilter(1, 1, 1, 1, 79, 79, -255, 0);
var bounds_yellow = bellFrontLt.petals_mc_1.nominalBounds;

var colorFilter_orange = new createjs.ColorFilter(1, 1, 1, 1, 255, -51, -255, 0); 
var bounds_orange = bellFrontLt.petals_mc_1.nominalBounds;

this.yellow_btn_1.addEventListener("click", change_color_yellow.bind(this));

function change_color_yellow()
{
	//alert("yellow button clicked");	
	bellFrontLt.petals_mc_1.filters = [ colorFilter_yellow ];
	bellFrontLt.petals_mc_1.cache(-bounds_yellow.width * 0.5, -bounds_yellow.height * 0.5, bounds_yellow.width, bounds_yellow.height);
	bellSideLt.petals_mc_1.filters = [ colorFilter_yellow ];
	bellSideLt.petals_mc_1.cache(-bounds_yellow.width * 0.5, -bounds_yellow.height * 0.5, bounds_yellow.width, bounds_yellow.height);	
}

this.orange_btn_1.addEventListener("click", change_color_orange.bind(this));

function change_color_orange()
{
	//alert("orange button clicked");	
	bellFrontLt.petals_mc_1.filters = [ colorFilter_orange ];
	bellFrontLt.petals_mc_1.cache(-bounds_yellow.width * 0.5, -bounds_yellow.height * 0.5, bounds_yellow.width, bounds_yellow.height);	
	bellSideLt.petals_mc_1.filters = [ colorFilter_orange ];
	bellSideLt.petals_mc_1.cache(-bounds_orange.width * 0.5, -bounds_orange.height * 0.5, bounds_orange.width, bounds_orange.height);
