Configuration Migration

Automatic migration from v1.0.0 configuration format:

// TablistConfigMigrator.java
public class TablistConfigMigrator {
    public MigrationResult migrateFromV1_0_0(Path oldConfigPath) {
        // Backup original configuration
        createBackup(oldConfigPath);
        
        // Convert TOML settings to new format
        TOMLConfig oldConfig = loadTOMLConfig(oldConfigPath);
        TablistConfig newConfig = convertToNewFormat(oldConfig);
        
        // Generate YAML templates from old settings
        YAMLTemplates templates = generateTemplatesFromConfig(oldConfig);
        
        // Validate and save new configuration
        validateConfiguration(newConfig, templates);
        saveNewConfiguration(newConfig, templates);
        
        return MigrationResult.SUCCESS;
    }
}

Boss Bar Integration

Dynamic boss bars with real-time content

// BossBarManager.java
public class BossBarManager {
    private final Map<UUID, List<ServerBossEvent>> playerBossBars = new ConcurrentHashMap<>();
    
    public void updateBossBar(ServerPlayer player, BossBarTemplate template) {
        ServerBossEvent bossBar = createBossBar(template);
        bossBar.setName(Component.literal(
            placeholderManager.replacePlaceholders(template.getText(), player)
        ));
        bossBar.setProgress(calculateProgress(template, player));
        bossBar.addPlayer(player);
        
        // Store for cleanup
        playerBossBars.computeIfAbsent(player.getUUID(), k -> new ArrayList<>()).add(bossBar);
    }
}

🔨 Technical Implementation

Performance Optimizations

Caching System

// TemplateCache.java
public class TemplateCache {
    private final Cache<String, CompiledTemplate> templateCache;
    private final Cache<String, List<Component>> renderedContentCache;
    
    public TemplateCache() {
        this.templateCache = Caffeine.newBuilder()
            .maximumSize(100)
            .expireAfterWrite(10, TimeUnit.MINUTES)
            .build();
            
        this.renderedContentCache = Caffeine.newBuilder()
            .maximumSize(1000)
            .expireAfterWrite(30, TimeUnit.SECONDS)
            .build();
    }
}

Async Processing

// AsyncTablistUpdater.java
public class AsyncTablistUpdater {
    private final ScheduledExecutorService executor = 
        Executors.newScheduledThreadPool(2, r -> {
            Thread t = new Thread(r, "NeoEssentials-Tablist");
            t.setDaemon(true);
            return t;
        });
    
    public CompletableFuture<Void> updateTablistAsync(ServerPlayer player) {
        return CompletableFuture.runAsync(() -> {
            TablistTemplate template = getTemplateForPlayer(player);
            List<Component> content = renderTemplate(template, player);
            
            // Switch back to main thread for packet sending
            MinecraftServer.execute(() -> sendTablistUpdate(player, content));
        }, executor);
    }
}

Animation Engine Implementation

Frame Management

// AnimationEngine.java
public class AnimationEngine {
    private final Map<String, AnimationDefinition> animations = new ConcurrentHashMap<>();
    private final Map<String, AnimationState> activeAnimations = new ConcurrentHashMap<>();
    private final ScheduledExecutorService animationExecutor;
    
    public void startAnimation(String animationId, AnimationDefinition definition) {
        AnimationState state = new AnimationState(definition);
        activeAnimations.put(animationId, state);
        
        scheduleAnimationUpdate(animationId, state);
    }
    
    private void scheduleAnimationUpdate(String animationId, AnimationState state) {
        animationExecutor.schedule(() -> {
            if (activeAnimations.containsKey(animationId)) {
                state.nextFrame();
                notifyAnimationUpdate(animationId, state.getCurrentFrame());
                
                if (state.hasMoreFrames() || state.isLooping()) {
                    scheduleAnimationUpdate(animationId, state);
                }
            }
        }, state.getFrameInterval(), TimeUnit.MILLISECONDS);
    }
}

Placeholder Integration

// AnimationPlaceholderProcessor.java
public class AnimationPlaceholderProcessor implements PlaceholderProcessor {
    private static final Pattern ANIMATION_PATTERN = 
        Pattern.compile("<anim:([^>]+)>([^<]*)</anim:[^>]+>");
    
    @Override
    public String processPlaceholders(String text, ServerPlayer player) {
        Matcher matcher = ANIMATION_PATTERN.matcher(text);
        StringBuffer result = new StringBuffer();
        
        while (matcher.find()) {
            String animationName = matcher.group(1);
            String content = matcher.group(2);
            
            AnimationFrame currentFrame = animationEngine.getCurrentFrame(animationName);
            String animatedContent = currentFrame.applyToText(content);
            
            matcher.appendReplacement(result, Matcher.quoteReplacement(animatedContent));
        }
        
        matcher.appendTail(result);
        return result.toString();
    }
}
