Build Status

Yugop.com(by Yugo Nakamura) style text animation effect re-created in javascript. Ported from my old Actionscript 3 file.

Quick start

npm i @gen/random-text -S
import RandomText from '@gen/random-text';

const randomText = new RandomText({
  str: 'string to animate',
  onProgress: str => { // callback for progress },
  onComplete: str => { // callback for completion }
});

See example folder for detailed usage

RandomText(options)

options

str: string

Target string to animate.

speed?: number

Number of characters per iteration (Defaults to 2). Note: Currently animation is not time-based so longer the str, longer the animation will take to complete. This might change in future to time-based animation.

placeholderChar?: string

String to represent for placeholder before the shuffling animation begins (Defaults to '_').

frameOffset?: number

Represents the base offset value for generated randoms (Defaults to 30). Bigger they are, longer the placeholder will be shown before shuffle.

charOffset?: number

Represents max offset amount for character to shuffle (Defaults to 20).

charStep?: number

Represents wait amount before character shuffling to start (Defaults to 10). Use with frameOffset to adjust effect.

minCharCode?: number

Represents minimum character to display while shuffling (Defaults to 22).

maxCharCode?: number

Represents maximum character to display while shuffling (Defaults to 122)

onProgress?: string => void

Callback function during animation. Animated string will be returned as first argument.

onComplete?: string => void

Callback function on animation complete. String will be returned as first argument which is likely to be the original target string(unless its a bug).
