Replay: Generate UI from Educational Video Games for Engaging Learning Experiences

TL;DR: Replay lets you extract functional UI components and product flows directly from educational video game recordings, transforming gameplay into interactive learning experiences.

Educational video games are a powerful tool for engaging students and reinforcing learning. But what if you could take the interactive elements of these games and repurpose them as standalone UI components for quizzes, tutorials, or interactive exercises? Enter Replay, the video-to-code engine that's revolutionizing how we extract and utilize UI from video content.

The Challenge: Bridging the Gap Between Gameplay and Learning#

Traditional methods of extracting UI elements from educational games are time-consuming and often inaccurate. Screenshots lack the dynamic behavior of interactive components, and manual reconstruction is a tedious process. We need a solution that understands the intent behind the UI interactions, not just the visual representation.

This is where Replay excels. Unlike screenshot-to-code tools that simply convert images into static layouts, Replay analyzes video recordings of gameplay to understand user behavior and reconstruct fully functional UI components. This "Behavior-Driven Reconstruction" approach unlocks a new level of efficiency and accuracy in educational content creation.

Replay: Behavior-Driven UI Generation from Video#

Replay leverages the power of Gemini to analyze video footage and generate clean, functional code. Here’s how it works:

1. •Video Input: You provide Replay with a video recording of gameplay demonstrating the UI elements you want to extract. This could be a tutorial section, a specific game mechanic, or an interactive quiz.
2. •Behavior Analysis: Replay analyzes the video, identifying UI elements, user interactions (clicks, hovers, drags), and the underlying logic.
3. •Code Generation: Based on the analysis, Replay generates clean, well-structured code (React, Vue, Svelte, etc.) that recreates the interactive UI component.
4. •Output: You get fully functional, customizable code that you can integrate into your learning platform, website, or application.

Step-by-Step Guide: Generating UI from an Educational Game#

Let's walk through a practical example of using Replay to extract a UI component from an educational video game. We'll use a hypothetical game that teaches basic arithmetic. Imagine the game presents a simple addition problem with draggable numbers.

Step 1: Record the Gameplay#

Record a short video (30-60 seconds) of yourself interacting with the addition problem. Ensure the video clearly shows the UI elements (numbers, operators, input fields) and your interactions (dragging numbers, submitting the answer).

💡 Pro Tip: Use a screen recording tool with good video quality and minimal background noise for optimal Replay performance.

Step 2: Upload the Video to Replay#

Navigate to the Replay platform (https://replay.build) and upload your video recording.

Step 3: Configure Replay Settings#

Configure the following settings:

• •Target Framework: Select the JavaScript framework you want to use (e.g., React).
• •Output Style: Choose a styling method (e.g., CSS modules, Tailwind CSS).
• •Component Name: Give your generated component a descriptive name (e.g.,
  text

  AdditionProblem
  ).

Step 4: Initiate Code Generation#

Click the "Generate Code" button and let Replay work its magic. The process typically takes a few seconds to a few minutes, depending on the complexity of the UI.

Step 5: Review and Customize the Code#

Once the code generation is complete, Replay will present you with the generated code. Review the code, making any necessary adjustments or customizations.

typescript
// Example React component generated by Replay
import React, { useState } from 'react';
import styles from './AdditionProblem.module.css';

interface Props {
  num1: number;
  num2: number;
}

const AdditionProblem: React.FC<Props> = ({ num1, num2 }) => {
  const [answer, setAnswer] = useState<number | null>(null);
  const [isCorrect, setIsCorrect] = useState<boolean | null>(null);

  const handleSubmit = () => {
    if (answer === num1 + num2) {
      setIsCorrect(true);
    } else {
      setIsCorrect(false);
    }
  };

  return (
    <div className={styles.container}>
      <p className={styles.problem}>{num1} + {num2} = ?</p>
      <input
        type="number"
        value={answer === null ? '' : answer}
        onChange={(e) => setAnswer(Number(e.target.value))}
        className={styles.input}
      />
      <button onClick={handleSubmit} className={styles.button}>Submit</button>
      {isCorrect === true && <p className={styles.correct}>Correct!</p>}
      {isCorrect === false && <p className={styles.incorrect}>Incorrect!</p>}
    </div>
  );
};

export default AdditionProblem;

Step 6: Integrate into Your Learning Platform#

Copy the generated code and integrate it into your learning platform or application. You can now use the extracted UI component as a standalone exercise or incorporate it into a larger learning module.

Key Benefits of Using Replay for Educational Games#

• •Rapid Prototyping: Quickly extract and prototype interactive elements from existing games.
• •Content Repurposing: Transform gameplay into engaging learning activities.
• •Increased Engagement: Integrate game-like UI into educational content to boost student motivation.
• •Reduced Development Time: Automate the process of UI reconstruction, saving valuable development time and resources.
• •Multi-page Generation: Replay can understand and generate multi-page flows, allowing you to extract more complex interactions.
• •Supabase Integration: Seamlessly integrate with Supabase for data storage and user authentication.
• •Style Injection: Customize the appearance of generated components using your preferred styling method.
• •Product Flow Maps: Visualize the user flow within the game and extract specific sequences of interactions.

Beyond Simple Components: Reconstructing Product Flows#

Replay goes beyond generating individual UI components. It can also reconstruct entire product flows from video recordings. This is particularly useful for creating interactive tutorials or demonstrations. Imagine recording a walkthrough of a complex game mechanic. Replay can analyze the video and generate a step-by-step interactive tutorial that allows students to practice the mechanic themselves.

📝 Note: Replay's ability to reconstruct product flows is a powerful tool for creating engaging and effective learning experiences.

Case Study: Interactive Math Quizzes#

A math education startup used Replay to extract interactive UI elements from existing math games. They were able to quickly create a library of interactive quizzes that integrated seamlessly into their online learning platform. This significantly reduced their development time and allowed them to focus on creating high-quality educational content.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited usage. Paid plans are available for higher usage and access to advanced features. Check the pricing page at https://replay.build for the latest details.

How is Replay different from v0.dev?#

While both tools aim to generate code from visual inputs, Replay focuses specifically on analyzing video to understand user behavior and reconstruct interactive UI. v0.dev primarily uses text prompts and may not capture the nuances of user interactions as effectively. Replay's behavior-driven reconstruction provides a more accurate and functional representation of the original UI.

What types of video games are compatible with Replay?#

Replay can analyze videos from a wide range of educational video games, including those built with Unity, Unreal Engine, HTML5, and other technologies. The key is to ensure the video clearly captures the UI elements and user interactions.

What JavaScript frameworks are supported by Replay?#

Replay currently supports React, Vue, and Svelte. Support for additional frameworks is planned for future releases.

⚠️ Warning: The accuracy of the generated code depends on the quality of the video recording. Ensure the video is clear, stable, and captures all relevant UI elements and user interactions.
