Usage

1. You have to wrap your app with the Provider:

// index.js
import React from "react";
import { render } from "react-dom";
import { Provider as FlyingScrollerProvider } from "react-flying-scroller";
import App from "./App";

const Root = () => {
  <FlyingScrollerProvider>
    <App />
  </FlyingScrollerProvider>,
};

render(<Root />, document.getElementById("root"))

2. Import 'Container' component and wrap the entire component you want to scroll through:

// App.js
import React from "react";
import { Container as ScrollContainer } from "react-flying-scroller";

const App = () => {
  return (
    <div className="app-container">
      <ScrollContainer>
        <div className="content"></div>
        <div className="content"></div>
        <div className="content"></div>
      </ScrollContainer>
    </div>
  );
};

export default App;

Please clearly set the container height:

//set height directly on the container
const App = () => {
  return (
    <div className="app-container">
      <ScrollContainer style={{ height: "1000px" }}>
        <div className="content"></div>
        <div className="content"></div>
        <div className="content"></div>
      </ScrollContainer>
    </div>
  );
};

//or set height to parent component
const App = () => {
  return (
    <div
      className="app-container"
      style={{
        display: "flex",
        flexDirection: "column",
        height: "100vh",
      }}
    >
      <ScrollContainer style={{ flex: 1 }}>
        <div className="content"></div>
        <div className="content"></div>
        <div className="content"></div>
      </ScrollContainer>
    </div>
  );
};

export default App;

3. Then import 'Board' component and place the component where you want it:

// App.js
import React from "react";
import {
  Container as ScrollContainer,
  Board as ScrollBoard,
} from "react-flying-scroller";

const App = () => {
  return (
    <div className="app-container">
      <ScrollBoard />
      <ScrollContainer>
        <div className="content"></div>
        <div className="content"></div>
        <div className="content"></div>
      </ScrollContainer>
    </div>
  );
};

export default App;

Direct scroll

You can scroll to specific component with Wrapper component and useDirectScroll hook

1. Import the Wrapper component and wrap the component you want to scroll directly:

// App.js
import React from "react";
import {
  Container as ScrollContainer,
  Board as ScrollBoard,
  Wrapper as ScrollWrapper,
} from "react-flying-scroller";

const App = () => {
  return (
    <div className="app-container">
      <ScrollBoard />
      <ScrollContainer>
        // Name it whatever you want!!
        <ScrollWrapper name="first">
          <div className="content"></div>
        </ScrollWrapper>
        <div className="content"></div>
        <div className="content"></div>
      </ScrollContainer>
    </div>
  );
};

2. Then import useDirectScroll hook and pass the name you set to the scroll wrapper as a property of the hook:

// App.js
import React from "react";
import {
  Container as ScrollContainer,
  Board as ScrollBoard,
  Wrapper as ScrollWrapper,
  useDirectScroll,
} from "react-flying-scroller";

const App = () => {
  return (
    <div className="app-container">
      // The hook returns a function that scrolls directly to the component
      <button onClick={useDirectScroll("first")}>go to first</button>
      <ScrollBoard />
      <ScrollContainer>
        // Name it whatever you want!!
        <ScrollWrapper name="first">
          <div className="content"></div>
        </ScrollWrapper>
        <div className="content"></div>
        <div className="content"></div>
      </ScrollContainer>
    </div>
  );
};

Now clicking the button, you can go directly to the specified component!

Options

Style

You can style each of the Board and Container components in an inline styling way:

// App.js
import React from "react";
import {
  Container as ScrollContainer,
  Board as ScrollBoard,
} from "react-flying-scroller";

const containerStyle = {
  height: "1000px",
};

const boardStyle = {
  height: "50px",
};

const App = () => {
  return (
    <div className="app-container">
      <Board style={boardStyle} />
      <ScrollContainer style={containerStyle}>
        <div className="content"></div>
        <div className="content"></div>
        <div className="content"></div>
      </ScrollContainer>
    </div>
  );
};

Avatar image

You can also add any avatar image you want:

// App.js
import React from "react";
import {
  Container as ScrollContainer,
  Board as ScrollBoard,
} from "react-flying-scroller";

import IronMan from "/images/IronMan.png";
import StandingMan from "/images/Standing.png";

// You must set both walking image and flying image.
const avatarImage = {
  Standing: StandingMan,
  Flying: IronMan,
};

const App = () => {
  return (
    <div className="app-container">
      <Board />
      <ScrollContainer avatarImage={avatarImage}>
        <div className="content"></div>
        <div className="content"></div>
        <div className="content"></div>
      </ScrollContainer>
    </div>
  );
};

it works like this!!

The avatar size is adjusted based on the height, and the avatar height is 1/2 of the board component height.

// App.js
import React from "react";
import {
  Container as ScrollContainer,
  Board as ScrollBoard,
} from "react-flying-scroller";

import IronMan from "/images/IronMan.png";
import StandingMan from "/images/Standing.png";

const avatarImage = {
  Standing: StandingMan,
  Flying: IronMan,
};

const App = () => {
  return (
    <div className="app-container">
      <Board style={{ height: "100px" }} /> //avatar height will be 50px
      <ScrollContainer avatarImage={avatarImage}>
        <div className="content"></div>
        <div className="content"></div>
        <div className="content"></div>
      </ScrollContainer>
    </div>
  );
};

Game

You can play simple game 🚀🚀

game example

Set the game options to the ScrollContainer's props.

// App.js
import React from "react";
import {
  Container as ScrollContainer,
  Board as ScrollBoard,
} from "react-flying-scroller";

import IronMan from "/images/IronMan.png";
import StandingMan from "/images/Standing.png";

const gameOptions = {
  range: {
    start: 5,
    end: 95,
  },
  difficulty: 1,
};

const App = () => {
  return (
    <div className="app-container">
      <Board style={{ height: "100px" }} />
      //set gameOptions
      <ScrollContainer gameOption={gameOptions}>
        <div className="content"></div>
        <div className="content"></div>
        <div className="content"></div>
      </ScrollContainer>
    </div>
  );
};

Game restart

When you clear the game, you can get a function to restart the game via the useGame hook. You can also get the game playable state

// App.js
import React from "react";
import {
  Container as ScrollContainer,
  Board as ScrollBoard,
  useGame,
} from "react-flying-scroller";

import Navigation from "/component/Navigation";
import IronMan from "/images/IronMan.png";
import StandingMan from "/images/Standing.png";

const gameOptions = {
  range: {
    start: 5,
    end: 95,
  },
  difficulty: 1,
};

const App = () => {
  const { gamePlayable, playAgain } = useGame();

  return (
    <div className="app-container">
      <Board style={{ height: "100px" }} />
      {!gamePlayable && (
        <>
          <Navigation />
          <div onClick={playAgain}>reGame</div>
        </>
      )}
      <ScrollContainer gameOption={gameOptions}>
        <div className="content"></div>
        <div className="content"></div>
        <div className="content"></div>
      </ScrollContainer>
    </div>
  );
};
