pixi-scrollbox

A configurable scrollbox designed for pixi.js.

Features:

  • scrollbox uses a mask to clip to desired boxWidth/boxHeight size
  • scrollbox scrolls with scrollbars (options.overflow=scroll)
  • scrollbox's scrollbars may be hidden when not needed (options.overflow=auto or hidden)
  • scrollbox may also be scrolled by dragging on the content window (options.dragScroll=true)

Rationale

I needed a scrollbox for the UI of my game and since I had this nifty pixi-viewport, I figured it wouldn't be much work to create it. Five hours later and I realized I was a bit off on my estimates. Hopefully others will find it useful.

Migration from v1 to v2

Scrollbox no longer exports a default object. Instead you need to use:

const Scrollbox = require('pixi-scrollbox').Scrollbox

or

import { Scrollbox } from 'pixi-scrollbox'

There were some minor name changes to the fade options. See documentation.

Simple Example

const PIXI = require('pixi.js')
const Scrollbox = require('pixi-scrollbox').Scrollbox

// create the scrollbox
const scrollbox = new Scrollbox({ boxWidth: 200, boxHeight: 200})

// add a sprite to the scrollbox's content
const sprite = scrollbox.content.addChild(new PIXI.Sprite(PIXI.Texture.WHITE))
sprite.width = sprite.height = 500
sprite.tint = 0xff0000

// force an update of the scrollbox's calculations after updating the children
scrollbox.update()

// add the viewport to the stage
const app = new PIXI.Application()
document.body.appendChild(app.view)
app.stage.addChild(scrollbox)

Installation

npm i pixi-scrollbox pixi-viewport pixi.js

or

yarn add pixi-scrollbox pixi-viewport pixi.js

Note: pixi-viewport and pixi.js are listed as peerDependency, which means you will need to manually install them if they're not already installed (this is to ensure you don't have two versions of these libraries).
