  • Here is main.js: 

    let myNumber = 5;

export function getMyNumber(){
return myNumber;
}

    here is importsForEvents.js 

    import { getMyNumber } from "./main.js";

    Purpose of the imports file is set to import for events.

    Why is getMyNumber() still undefined when ran on start of layout in event sheet as script?

  • Im not sure what i am doing wrong,

    Lets say i create a class : 

    class myClass
{
Let x = 5;

alertUser()
{ 
alert('works');
}
}

    Now in main.js i need to import this class right ? 

    import * as myClass from ("./myClass.js");

    Even if i add export to the class, this still gives me undefined class error, what am i doing wrong? I know programming i am just stuck on the import/export part.

    I am trying this in the main.js file so i am not trying to run scripts from event sheet.

  • Edit: so importing and exporting functions is working for me.

    How do i import a class for example a sub class that i made ? Do i have to instantiate the class before using it like 

    Let myClass = new myClass():

  • Alright so i solved it by doing 

    // I import the class named myClass from my js file, the class has an export tag. 
import { myClass } from "./myclass.js" ;

// I instantiate the class
let customClass = new myClass();
// I can now use the functions declared inside myClass
customClass.runMyFunction();

    This is working, i dont know if i am doing it correct, but this way its working. I am getting more familiar with the import/export in construct.

  • The code in your initial post appears to be correct. Maybe you didn't set the right script purpose properties. The easiest way to get help is to share a project file, so others can see exactly what you've done - otherwise all we can do is guess.

    Basically the code above is all i did to test the import/export. I solved it as the problem was on my end, i forgot to export the class properly. Thanks for your reply
