Always match anchor and position: for a centered anchor, position at the center of the screen. Adjust the original size and aspect ratio of my assets, check and fix the layering and container position
User prompt
Set the anchor to (0.5, 0.5). Set the position to the center of the screen: `x = screenWidth / 2`, `y = screenHeight / 2`. Set the width and height to match the screen size.
User prompt
Incorrect postion for Backgroundsongselector asset, I'm only see it at the right corner, make it fit to the size of the screen 2048*2372
User prompt
Homepage errors fix it, rewrite codes for all the homepage elements by adding backgroundsongselector asset, selector UI asset for Sky Journey, Night Pulse and Sunrise Waltz
User prompt
Check clearing or overwriting elements issues, and check which elements are not added to the stage and check the asset initialization problems, also check the global state issues
User prompt
Check the layering and visibility issues for homepage elements, and check incorrect positioning for homepage
User prompt
Add Select a Song as the title of homepage, Sky Journey, Night Pulse and Sunrise Waltz as song selection within Selector UI

Correct his error, tired with too much homepage elements errors
User prompt
All of the homepage elements disappeared, fix this error

I've analyzed the issues in your code. Here's a breakdown of the problems and solutions: ### 1. Duplicated Sky Journey Titles **Problem**: This occurs because: 1. The `SongCard` class creates a title text element 2. The `showHome()` function creates another title text element for the same song 3. Both are added to the same container **Solution**: Modify the `SongCard` class to only create the cover image, and handle the title text separately in `showHome()`: ```javascript // Updated SongCard class var SongCard = Container.expand(function () { var self = Container.call(this); self.songId = ''; self.cover = null; self.init = function (songId, colorAsset) { self.songId = songId; if (self.cover) { self.removeChild(self.cover); } self.cover = self.attachAsset(colorAsset, { anchorX: 0.5, anchorY: 0.5 }); }; return self; }); ``` ### 2. Song Selector Positioning Issues **Problem**: The cards aren't centered because: 1. Incorrect positioning calculations 2. Not accounting for container offsets 3. Improper handling of screen dimensions **Solution**: Fix the positioning logic: ```javascript function showHome() { // ... existing code ... // Fixed positioning calculations var cardSpacing = 450; var cardCount = SONGS.length; var cardWidth = 400; var totalWidth = (cardCount - 1) * cardSpacing + cardWidth; var startX = -totalWidth / 2; // Center in container var cardY = -100; // Move cards higher up // Create song cards for (var i = 0; i < SONGS.length; i++) { (function(idx) { // Create song card var card = new SongCard(); card.init(SONGS[idx].id, SONGS[idx].cover); card.x = startX + idx * cardSpacing; card.y = cardY; card.interactive = true; card.down = function(x, y, obj) { selectedSong = SONGS[idx]; setGameState('STORY'); }; homeScreen.addChild(card); songCards.push(card); // Create song name text var songNameText = new Text2(SONGS[idx].title, { size: 64, fill: "#ffffff", font: "Arial" }); songNameText.anchor.set(0.5, 0.5); songNameText.x = startX + idx * cardSpacing; songNameText.y = cardY + 300; // Position below card homeScreen.addChild(songNameText); })(i); } // ... existing code ... } ``` ### 3. Other Songs Not Appearing **Problem**: Only the first song appears because: 1. The loop variable `i` isn't properly captured in closures 2. Song references aren't preserved correctly **Solution**: Fix the closure scope: ```javascript // In showHome() loop for (var i = 0; i < SONGS.length; i++) { (function(index) { // Create a closure to capture index var song = SONGS[index]; // Capture current song // ... card creation code ... card.down = function(x, y, obj) { selectedSong = song; // Use captured song reference setGameState('STORY'); }; // ... rest of code ... })(i); // Pass current index } ``` ### 4. Storyline Position at Bottom **Problem**: The storyline is positioned too low because: 1. The Y-position calculation doesn't account for screen size 2. No vertical centering **Solution**: Adjust the positioning: ```javascript function showStory() { // ... existing code ... // Center the storyline vertically storyText.anchor.set(0.5, 0.5); storyText.x = screenWidth / 2; storyText.y = screenHeight * 0.4; // 40% from top // Position continue button lower continueButton.y = screenHeight * 0.7; // 70% from top // ... existing code ... } ``` ### Full Corrected `showHome()` Function Here's the complete fixed version: ```javascript function showHome() { clearGUI(); songCards = []; var screenWidth = LK.width || 2048; var screenHeight = LK.height || 2732; // Create a centered container for the homepage var homeScreen = new Container(); // Title var title = new Text2(selectedLanguage === 'zh' ? "选择歌曲" : "Select a Song", { size: 100, fill: "#ffffff", font: "Arial" }); title.anchor.set(0.5, 0.5); title.x = 0; title.y = -screenHeight/2 + 150; homeScreen.addChild(title); // Center song cards var cardSpacing = 450; var cardCount = SONGS.length; var cardWidth = 400; var totalWidth = (cardCount - 1) * cardSpacing + cardWidth; var startX = -totalWidth / 2; var cardY = -100; // Create song cards for (var i = 0; i < SONGS.length; i++) { (function(index) { var song = SONGS[index]; // Create song card var card = new SongCard(); card.init(song.id, song.cover); card.x = startX + index * cardSpacing; card.y = cardY; card.interactive = true; card.down = function(x, y, obj) { selectedSong = song; setGameState('STORY'); }; homeScreen.addChild(card); songCards.push(card); // Create song name text var songNameText = new Text2(song.title, { size: 64, fill: "#ffffff", font: "Arial" }); songNameText.anchor.set(0.5, 0.5); songNameText.x = startX + index * cardSpacing; songNameText.y = cardY + 300; homeScreen.addChild(songNameText); })(i); } // Position the homeScreen container at screen center homeScreen.x = screenWidth / 2; homeScreen.y = screenHeight / 2; // Add to GUI gui.center.addChild(homeScreen); } ``` ### Key Fixes Summary: 1. **Duplicated Titles**: - Removed title creation from SongCard class - Handle titles separately in showHome() 2. **Positioning**: - Fixed card positioning calculations - Added proper vertical spacing - Centered all elements in container 3. **Missing Songs**: - Fixed closure scope to capture song references - Used immediately-invoked function expressions (IIFE) 4. **Storyline Position**: - Adjusted Y-position to 40% from top - Positioned continue button at 70% from top These changes should resolve all the issues you're experiencing with the home screen and storyline positioning. The song selector should now appear properly centered with all songs visible, without duplicates, and the storyline should be positioned higher on the screen.

Same error again
User prompt
Still occurring the same error
User prompt
Center and space. Calculate positions so all cards are centered and spaced evenly. UI best practices.Title at top center, avoid top-left, all elements visible. Global variables. Arrays/variables for UI elements in global scope.
User prompt
Based on your advices, fix the problems for homepage
User prompt
Still results in duplicated Sky Journey, only one Sky Journey is in the homepage, and I still cannot see Night Pulse and Sunrise Waltz in the homepage
User prompt
Remove duplicated Sky Journey, move it to the centre of the screen, add Night Pulse and Sunrise Waltz at the home screen and both of them are within the SelectorUI
User prompt
The Sky Journey are duplicated, make sure that Song Cover 1 only appear as the background of gameplay mode for Sky Journey, same as other songs
User prompt
The song selector is disappeared, repositioned all the elements at the homepage within the screen, the upper centre is the title Select a Song, and continue with Sky Journey, Night Pulse and Sunrise Waltz within the asset Selector UI
User prompt
Move up the song selector to the centre of the homepage
User prompt
Fix all of the elements within the screen of 2048x2732, in the centre of the homepage
