pixi-mousewheel - Plugin for pixi.js

About

This plugin for pixi.js automatically dispatches mousewheel scroll events for pixi display-objects. It only fires the event for objects that are interactive and have a special flag set. When scrolling a said display-object, the default document scroll is being blocked. Additionally, it normalizes the mousewheel delta for cross-browser consistency.

Documentation

To enable mousewheel events for any display-object, set the interactiveMousewheel flag on it to true. The mousewheel event will be dispatched via the standard pixi EventEmitter.

displayObject.interactiveMousewheel = true
displayObject.on('mousewheel', (delta, event) => {
    myOtherDisplayObject.y += delta * 100
})

• The delta is the amount of scrolling normalized to [-1,1].
• The event is the native DOM mousewheel event. Use this if you need the raw data.

Installing

Include the dist/pixi-mousewheel.js or dist/pixi-mousewheel.min.js in your html document after pixi.js.
