[Open-Source] - Need Help Clearing Up 4 Variable Implicitly Declared Warnings

Hi,

I am hoping someone here can help with 4 JavaScript warnings.
This issue for all 4 is that the variables are “Implicitly Declared”.

MIT Open Source Project Code Can Be Downloaded Below:

Let me know how to fix the below, thanks!

Jesse


In “input.js” we declare the following two variables:

let MouseX = 0;
let MouseY = 0;

In “initialize.js” we access the two variables:

    canvas.addEventListener("mousemove", function(event)
    {
        let canvas = document.getElementById("ScreenCanvas");

        let rect = canvas.getBoundingClientRect();
//        import { MouseX } from './input.js';
//        import { MouseY } from './input.js';
        MouseX = Math.floor(event.clientX - rect.left);
        MouseX = (Math.floor(MouseX * (800 / BrowserWidth)));

        MouseY = Math.floor(event.clientY - rect.top);
        MouseY = (Math.floor(MouseY * (480 / BrowserHeight)));
    });


I haven’t dealt with exporting variables before (only functions), so this is a new one to me.

Regardless of whether a variables is declared as ‘let’ or ‘const’, in the import module the variables are read-only

From MDN

The static import declaration is used to import read-only live bindings which are exported by another module. The imported bindings are called live bindings because they are updated by the module that exported the binding, but cannot be re-assigned by the importing module.

So if you try

import { MouseX } from './input.js';
MouseX = some value here

It will throw a type error

TypeError: Assignment to constant variable.

Even though it was originally declared with let.

However if you do the following

Export module

export let mouseX = 5;
export let mouseY = 10;

export const incMouseX = () => {
  mouseX++;
}

export const incMouseY = () => {
  mouseY++;
}

Import module

import { incMouseX, incMouseY, mouseX, mouseY } from './my-import.js';

console.log(mouseX, mouseY); // 5 10
incMouseX();
incMouseY();
console.log(mouseX, mouseY); // 6 11

You can see this confirms the read-only live bindings bit.

New to me as well.

The ‘Implicitly Declared’ global errors you are getting are because you have commented out the imports and are declaring MouseX and MouseY without ‘let’ or ‘const’

Hi,

Thanks for the info…

In “input.js” I now have:

export let MouseX = 0;
export let MouseY = 0;

In “initialize.js” I now have:

    canvas.addEventListener("mousemove", function(event)
    {
        let canvas = document.getElementById("ScreenCanvas");

        let rect = canvas.getBoundingClientRect();
        import { MouseX } from './input.js';
        MouseX = Math.floor(event.clientX - rect.left);
        import { MouseY } from './input.js';
        MouseX = (Math.floor(MouseX * (800 / BrowserWidth)));

        MouseY = Math.floor(event.clientY - rect.top);
        MouseY = (Math.floor(MouseY * (480 / BrowserHeight)));
    });

But now when I inspect the code, I have 7 errors and 319 weak warnings?

If you use so many global variables, you should really re-think your concept.

Hi,

Yes, many global variables.
Can you provide another suggestion?
I need a way for information to be shared between JavaScript files…

Jesse

Create a class, create an instance an share the object. Then you can also modify the objects attributes in all files

Hi,

Ok, thanks - will research and implement JavaScript Classes…

Jesse

Hi,

I almost got it working with a new JavaScript Class.

New “classes.js” (Loaded first before all other scripts):

class InputClass {
    constructor(MouseTouchX, MouseTouchY) {
        this.MouseTouchX = 0;
        this.MouseTouchY = 0;
    }
}

const InputClassObject = new InputClass(0, 0);

“initialize.js”:

    canvas.addEventListener("mousemove", function(event) {
        let canvas = document.getElementById("ScreenCanvas");

        let rect = canvas.getBoundingClientRect();

        InputClassObject.MouseTouchX = Math.floor(event.clientX - rect.left);
        InputClassObject.MouseTouchX = (Math.floor(InputClassObject.MouseTouchX * (800 / BrowserWidth)));

        InputClassObject.MouseTouchY = Math.floor(event.clientY - rect.top);
        InputClassObject.MouseTouchY = (Math.floor(InputClassObject.MouseTouchY * (480 / BrowserHeight)));
    });

I am getting two warnings now:
Unused perimeter MouseTouchX
Unused perimeter MouseTouchY
in the following line:
constructor(MouseTouchX, MouseTouchY) {

Let me know, thanks!

Jesse

It’s what it says. You do not use the parameter in the constructor. If you don’t need them, remove them…

Ok, got it - thanks!

(or probably, the more useful correction… use them, assuming you dont want every object to initialize to 0,0…)
