Adobe Animate HTML 5 Error when accessing internal library via external js script

[Deni318644749r7p]

Recently started learning Javascript and here is the problem When trying to access the internal Adobe Animate library through an external JS script, it swears and writes an error And if I write this script inside Adobe Animate it works fine, please help

let myBlue = new lib.blueShape;

exportRoot.addChild(myBlue);

let xPosition = Math.floor(Math.random()*700);

let yPosition = Math.floor(Math.random()*700);

myBlue.x = xPosition;

myBlue.y = yPosition;

root.push(myBlue);

 throws an error on - let myBlue = new lib.blueShape;

[kglad]

you have to wait until the library is initialized to access it. 

and that should be

new lib.blueShape();

[Deni318644749r7p]

Thanks for the reply, but it still gives the same error.

[kglad]

you still have a timing issue.  and then you'll need a lib reference.

[Deni318644749r7p]

Sorry for my bad English, maybe I don't understand something, how can I write a script correctly?

[kglad · Accepted solution]

1. remove your js file from the include panel

2. use code to reference your library (and you'll need the main timeline, too)

3. load your js with code

// don't use "var"

tl = this;  // main timeline reference
LIB = lib;  // library reference

// load your js file(s)
var queue = new createjs.LoadQueue();
queue.loadManifest([
"ext_file.js"
]);

in ext_file.js you can use:

let myBlue=new LIB.blueShape();

tl.addChild(myBlue);

[Deni318644749r7p]

var queue = new createjs.LoadQueue(); queue.loadManifest([ "ext_file.js" ]); This is how I add the code well, I need something from the ext_file.js file to access the Adobe Animate library, and not from the timeline

[kglad · Accepted solution]

i showed you how to do that

in your fla

// don't use "var"

tl = this;  // main timeline reference
LIB = lib;  // library reference

// load your js file(s)
var queue = new createjs.LoadQueue();
queue.loadManifest([
"ext_file.js"
]);

in your external js file

let myBlue=new LIB.blueShape();

tl.addChild(myBlue);

 It's my fault, everything works, thank you very much!

[kglad]

you're welcome

 Sorry for another question, although it is not on the local topic. Here's how to make an object from the scene added to an array, so that my platforms would have the same properties, so that I would not write each platform separately in actionscrip 3.0 it looked like this

var list_platforms: Array = new Array();

init();
function init(){
for (var i:uint = 0; i < numChildren; i++){
if (getChildAt(i) is Platform){
list_platforms.push(getChildAt(i));
}

how will it look like in js?

[kglad]

are you trying to find the linkage id of objects, or how to use arrays?

[Deni318644749r7p]

 I want to copy movie clips on the canvas, for example platforms, so that they would be under the same name and that they would have one property, so that I wouldn’t call each platform like platform 1, platform 2 and so on, of course you can’t understand what I want to explain

[kglad]

you're still talking about html5/canvas, correct?

is Platform a linkage id and you're trying to find instances with that linkage id?

[Deni318644749r7p]

Yes, on actionscrip 3.0 the script looked like this

var list_platforms: Array = new Array();

init();
function init(){
for (var i:uint = 0; i < numChildren; i++){
if (getChildAt(i) is Platform){
list_platforms.push(getChildAt(i));
}

On js, I don’t know how it is written, the script indicates that when copying the platform, it automatically adds to the array, thereby one name from the library for all copied objects

[kglad]

you can find the linkage name using the following, but how to compare that to something needs more work:

getMCSymbolPrototype(this.getChildAt(i)).constructor

[Deni318644749r7p]

 I suspected that through the constructor, well, what does the script look like in full?

[kglad]

init();
function init(){
for (var i = 0; i < numChildren; i++){
console.log(getMCSymbolPrototype(this.getChildAt(i)).constructor);

}

[Deni318644749r7p]

 I can’t understand this script, I will try to do something, thanks for the answer, I won’t bother you

[kglad]

use the script and open the developer console when testing.

[Deni318644749r7p]

Yes, I do that, but it gives an error in the console

[kglad]

what error?

[Deni318644749r7p]

I don’t understand why I had an error, I didn’t write the way you wrote to me the first time, now it displays to me without an error, well, I don’t understand how I can add a property now, well, for example, so that when you click the mouse they disappear

[kglad]

you're trying to add a property to what?

[Deni318644749r7p]

Here to these objects in the C_link library so that they have one function, for example, these are coins, when pressed, they disappear
