🔍 智能搜索集成

参数规格说明
拦截方法populateChildren(Ljava/lang/String;)V
注入位置@At("TAIL")
Mixin 类AbstractGameRulesScreenRuleListMixin
查询标准化filter.toLowerCase(java.util.Locale.ROOT)
搜索状态判断isSearching = !currentFilter.isEmpty()
动态展开规则`isExpanded = isSearching
重建调用collapsible_game_rules$updateVisibleEntries()

📖 机制概述

在原生 Minecraft 中,游戏规则搜索框通过比对规则名称与描述来筛选列表。若在折叠界面中直接采用原版逻辑,极易发生搜索结果被隐藏在未展开文件夹内的状况。

Smart Search Integration 通过即时监听搜索框输入来解决此问题。每当搜索框内存在有效关键字时,所有包含匹配规则的分类都会自动动态展开,让搜索结果一览无遗,无需额外手动点选。

💻 技术实现细节

1. @Inject 注入点

Mixin 拦截原版 populateChildren 方法的末尾(TAIL):

java
@Inject(method = "populateChildren(Ljava/lang/String;)V", at = @At("TAIL"))
private void collapsible_game_rules$onPopulateChildren(String filter, CallbackInfo ci) {
    this.collapsible_game_rules$currentFilter = (filter != null) ? filter.toLowerCase(java.util.Locale.ROOT) : "";
    // Save the currently generated list of all entries
    this.collapsible_game_rules$allEntries = new ArrayList<>(this.children());
    this.collapsible_game_rules$updateVisibleEntries();
}

2. 搜索状态动态判断

updateVisibleEntries() 中,动态计算类别的展开状态:

java
boolean isSearching = !this.collapsible_game_rules$currentFilter.isEmpty();
final String finalPersistenceKey = persistenceKey;
boolean isExpanded = isSearching || GameRuleStateConfig.isExpanded(finalPersistenceKey);

3. 无损状态恢复

由于 isSearching 仅在过滤活跃期间生效,当玩家清空搜索框时,界面会立即回复为 GameRuleStateConfig 中记录的玩家偏好展开状态,绝不会覆盖或重设硬盘上的本地配置。
