Need help, trying to make small app to override Xbox controller output

Hello to anyone reading this.

I’m trying to make a small bit of code, something that can override the controller and display on a site like

I believe it’s possible, but I know nothing about writing code.

Controller in question is a Elite 2, but highly doubt that makes any difference, as it’s a joystick axis x and y that I want to override.

Just need to make something short and simple. Example: controller plugged in, functions as intended, web interface captures the devices input. Start code or scipt and it reads as if I just made the movement with my thumb on the controller joystick.

Huge thanks for taking the time to read!

If anything, if there’s a how-to for dummies on this, would be EXTREMELY appreciated.
