yy-input

basic input support for touch, mouse, and keyboard

rationale

I used this in all my games, so I decided to centralize and share it. This is a very simple class that emits events after a touch, mouse, or keyboard event. The events are tied to an HTMLElement.

installation

npm i yy-input

simple example

const Input = require('yy-input')

this.input = new Input()
this.input.on('down', 
    function down(x, y)
    {
        console.log('You clicked at ' + x + ', ' + y)
    })

     * @event up(x, y, { input, event, id }) emits when touch or mouse is up or cancelled
     * @event move(x, y, { input, event, id }) emits when touch or mouse moves (even if mouse is still up)
