About This Log

This document chronicles the collaborative development of the Wordiverse word search game using GitHub Copilot in Visual Studio Code. Each entry captures the conversation, code, and reasoning behind our design decisions, serving as a learning resource for students and educators.

First Copilot Collaboration (June 26, 2025)
Teacher: I am a high school computer science teacher and this is a word search game you helped me write 3 months ago. I want to upgrade it and include a detailed chat log of our development so my students can learn how to code in VSCode with a Copilot assistant. I've included a file: copilotShellSampleChatLog.html that I like as a framework for recording our work. Can you create a new document, 'wordiverseChatLog.html' modeled after the sample that will serve as a guide to the work we're doing? Let's let this discussion serve as our first entry!
Copilot: Absolutely! I've created wordiverseChatLog.html modeled after your sample. This log will document our collaborative coding journey, including your requests and my responses, to help your students learn how to use Copilot in VS Code. Each section will capture a step in our development process, with clear formatting for both teacher and Copilot messages. Future entries can be added as you continue to work on the project.
Enabling User Play
Teacher: For our next collaboration, section-title = "Enabling User Play" I'd like to refactor the code so that a player can highlight a keyword in the grid as they find a keyword. When found, it should light up with the associated color in the 'Placed Words' list and the entry in the list should be bolded and italicized as 'found' Please explain your methodology and provide pertinent JavaScript and CSS snippets to document your solution. I'm open to other suggestions if you see improvements in my directives.
Copilot: To enable interactive play, I recommend the following methodology:
  1. Grid Cell Selection: Allow users to click and drag (or click start/click end) to select a sequence of grid cells.
  2. Word Detection: When a selection is made, check if the selected sequence matches any placed keyword (forwards or backwards).
  3. Visual Feedback: If a match is found:
    • Highlight the selected grid cells with the word's associated color.
    • Update the corresponding entry in the 'Placed Words' list: apply the color, and add font-weight: bold; font-style: italic; to indicate it is found.
  4. State Tracking: Maintain a found property for each placed word to prevent duplicate marking and to support end-of-game logic.

Here are the key code snippets to implement this feature:

/* CSS: Highlight found words and grid cells */
.found-word {
    font-weight: bold;
    font-style: italic;
    background-color: var(--found-color, #ffe066);
    transition: background 0.3s;
}
.found-cell {
    border: 2px solid var(--found-color, #ffe066) !important;
    background-color: var(--found-color, #ffe066) !important;
    color: #222;
}
// JavaScript: Add to your grid rendering and event logic
// 1. Track selection
let selection = [];
let isSelecting = false;

gridContainer.addEventListener('mousedown', (e) => {
    if (e.target.classList.contains('ltr')) {
        isSelecting = true;
        selection = [e.target];
        e.target.classList.add('selected');
    }
});
gridContainer.addEventListener('mouseover', (e) => {
    if (isSelecting && e.target.classList.contains('ltr')) {
        if (!selection.includes(e.target)) {
            selection.push(e.target);
            e.target.classList.add('selected');
        }
    }
});
gridContainer.addEventListener('mouseup', () => {
    isSelecting = false;
    // Check if selection matches a placed word
    const selectedCoords = selection.map(cell => [parseInt(cell.dataset.row), parseInt(cell.dataset.col)]);
    const foundWord = placedWords.find(pw =>
        arraysEqual(selectedCoords, pw.locnVector.map(loc => [loc.row, loc.col])) ||
        arraysEqual(selectedCoords.reverse(), pw.locnVector.map(loc => [loc.row, loc.col]))
    );
    if (foundWord && !foundWord.found) {
        // Mark as found
        foundWord.found = true;
        selection.forEach(cell => {
            cell.classList.add('found-cell');
            cell.style.setProperty('--found-color', foundWord.color);
        });
        // Update Placed Words list
        const listItem = document.getElementById('word-list-' + foundWord.word);
        listItem.classList.add('found-word');
        listItem.style.setProperty('--found-color', foundWord.color);
    }
    // Clear selection
    selection.forEach(cell => cell.classList.remove('selected'));
    selection = [];
});

function arraysEqual(a, b) {
    return a.length === b.length && a.every((v, i) => v[0] === b[i][0] && v[1] === b[i][1]);
}

Suggestions: You may also want to add touch support for mobile, and a visual indicator for already found words in the grid. Consider adding a "words found" counter for extra feedback.

Summarizing User Play

User Play Logic:
The Wordiverse game now supports interactive, user-friendly play through a series of clear, staged steps:

  1. Click/toggle letters in the grid: Users select or deselect grid letters by clicking. Each selected cell is visually highlighted.
  2. View their values: The app collects the values (letters) of the selected cells for further processing.
  3. Alphabetize their values: The selected letters are alphabetized to allow for flexible word matching, regardless of selection order.
  4. Scan for a match with placed words: The app compares the alphabetized selection to the letters attribute of each PlacedWord object.
  5. If a match is found: The selected cells are colorized using the word’s assigned color, the word is crossed out in the placed words list, and the words found counter is updated.
  6. Clear Selection: Users can clear their current selection at any time using the "Clear Selection" button, which is conveniently placed next to the "Check Word" button.

Key JavaScript:

  • PlacedWord.js class:
    The PlacedWord class now includes a letters attribute, which stores an alphabetized string of the word’s letters. This enables flexible matching regardless of the order in which the user selects the letters.
    class PlacedWord {
        constructor(word, color, locnVector) {
            this.word = word;
            this.color = color;
            this.locnVector = locnVector;
            this.letters = word.split('').sort().join('');
        }
        // ...
    }
  • checkForMatch function:
    This function (user-inspired!) is central to gameplay. It alphabetizes the selected letters and checks for a match with any placed word. If a match is found, it colorizes the selection, crosses out the word in the list, and updates the counter.
    function checkForMatch() {
        const checkedLetters = selection.map(cell => cell.textContent).join('');
        const alphabetizedCheckedLetters = checkedLetters.split('').sort().join('');
        let foundWord = null;
        for (let pw of placedWordInfo) {
            if (pw.letters === alphabetizedCheckedLetters) {
                foundWord = pw;
                break;
            }
        }
        if (foundWord) {
            // Colorize, cross out, update counter, etc.
        }
        // Selection is only cleared on success
    }

Important CSS:
The following CSS classes provide clear visual feedback for user actions:

  • .selected: Highlights currently selected grid cells.
    .selected {
        outline: 2px dashed #007bff;
        background-color: #e6f2ff;
    }
  • .found-cell: Styles cells that are part of a found word, using the word’s color.
    .found-cell {
        border: 1px solid #ccc !important;
        background-color: var(--found-color, #ffe066) !important;
        color: #222;
        /* ... */
    }
  • .found-word: Applies a line-through and color to found words in the list.
    .found-word {
        font-weight: bold;
        font-style: italic;
        background-color: var(--found-color, #ffe066);
        transition: background 0.3s;
    }

This staged, user-driven approach has made the game more intuitive and visually engaging, while the modular code and CSS ensure maintainability and clarity for classroom use.

Teacher's note: While trying to implement Copilots suggestions in Collaboration#2, we hit many problems. Eventually, I had to start over and break things down step by step. Here's the prompt I gave Copilot for this Collaboration, #3:

Teacher:

We did a lot since our last section. Our many attempts to utilize your suggestions failed, I believe, because we were doing too much at a time. I suggested we do things in stages: Click/toggle letters in the grid; View their values; Alphabetize their values; Scan to see if there's a match with placed words; If a match is found, colorize the selection; Cross out the placed word in the list; Update the words found count. We also we incorporated a 'Clear Selection' button placed it near the 'Check Word' button. At this time, we are not 'dragging' solutions, just clicking. We also updated the class 'PlacedWord.js' with a new attribute, 'letters' to assist in finding matches. Let's add a third section with section-title: "Summarizing User Play" in which we summarize the logic being used for game play along with meaningful snippets. Let's be sure to mention the PlacedWord.js class and focus on the function 'checkForMatch' (which was my idea!) Mention the important CSS we used as well

Sometimes we can get greedy and ask Copilot to do too much!?

Addressing browser width problems

Problem: The Wordiverse app is not currently designed for mobile or small-screen environments. The grid and input areas require a minimum width for usability and proper display.

Solution: We added a warning message that appears when the browser window is less than 1000px wide. The main input and grid areas are hidden in this case, and users are prompted to use a desktop or resize their browser. This is achieved with a #mobileWarning div and a CSS media query:

@media (max-width: 999px) {
    #primaryContent, #jumbotron {
        display: none !important;
    }
    #mobileWarning {
        display: block !important;
    }
}
#mobileWarning {
    display: none;
    background: #ffdddd;
    color: #a94442;
    border: 2px solid #a94442;
    border-radius: 8px;
    margin: 2em auto;
    padding: 2em;
    max-width: 600px;
    text-align: center;
    font-size: 1.3em;
    font-weight: bold;
}

This ensures users are clearly informed and prevents layout issues on unsupported devices.
