How can I replace "this.instance_vars" method?

I'm porting Globals 2.0 plugin to the C3Runtime, and I faced the next problem.

In Construct 2 SDK was "this.instance_vars" method. Using this method, you can get an array of values ​​of the object's instance variables. Using JSON.stringify(this.instance_vars) it looks like this:

But Construct 3 SDK doesn't have this method. You can only get the count of instance variables and their values by index. The Globals plugin uses this method to store the values ​​of instance variables as a JSON string (as in the image above).

How to solve this problem?

You can only get the count of instance variables and their values by index.

You can use that to make an array.

I tried to implement this with an array and the values ​​in the array were set. But only at the start of the layout.

How to check if the values ​​of instance variables have changed, and if they changed, set the values ​​in the array to the values of instance variables.

Here is my code in c3runtime/instance.js:

	this.instance_vars = [];
	this.defaultVarsValues = "";
			
	for (let i = 0; i < this.GetInstance().GetInstanceVariableCount(); i++)
	{
		this.instance_vars[i] = this.GetInstance().GetInstanceVariableValue(i);
		this.defaultVarsValues = JSON.stringify(this.instance_vars);
	}
