Passing variable to a graphic symbol instance

Hi there,

New to Adobe Animate. Is there a way to pass variables to instances created via code?

I've created a symbol that moves left 12 frames and then right 12 frames back to the same spot.

When creating an instance using the Linkage property and the code:

var example = new lib.linkageText();
this.addChild(example);

is there a way I can pass a variable through to the instance?

For example, is there a way to pass a variable that is the speed for how fast it moves left then right? Something like:

var example = new lib.linkageText(100);
this.addChild(example);

Hi.

To deal with constructor arguments you would have to deal with prototypes and other ES5 advanced concepts.

In your case, an easier approach would be to set a property for your instance when you instantiate it:

var example = new lib.linkageText();
example.x = 200;
example.y = 200;
example.speed = 30; // custom property
this.addChild(example);

Then you can have a code that reads this property inside of the instance you just created.

I hope it makes sense.

JC

Hi JC,

This makes sense, but do I need to define the property somewhere in the symbol?

I added your code above:

var example = new lib.linkageText();
example.x = 200;
example.y = 200;
example.speed = 30; // custom property
this.addChild(example);

Then in frame 1 of the symbol, in the Actions, I did:

console.log(speed)

and then tried

console.log(this.speed)

But when I look at the console, it has 'Uncaught ReferenceError: speed is not defined'.

Hi.

Your code should've worked.

Are you logging from within some function?
