Mouse-position NPM

mouse-position

A module for getting the current mouse position on an element, designed for use in games and animations.

Usage

mouse = mousePosition(element, listener)

Start watching element for mousemove events. If you don't pass an element, mouse will watch the entire browser window.

listener will attach the listener event to another element – helpful, for example, to catch movement across a larger area but still receive positions relative to element.

mouse0

The current horizontal position of the mouse, in pixels.

mouse1

The current vertical position of the mouse, in pixels.

mouse.prev0

The previous horizontal position of the mouse, in pixels.

mouse.prev1

The previous vertical position of the mouse, in pixels.

mouse.on('move', callback(event))

Called every time the mouse is moved anywhere on the targeted element.

mouse.flush()

Call this method at the end of each frame to update the prevX and prevY values – you won't get mousemove events every frame, so if you don't update this you might get incorrect values.
