📖 Overview

When managing modpacks with hundreds of game rules, expanding or collapsing categories one by one can become repetitive.

Global Actions introduces a dual-button header permanently anchored at Index 0 of the Game Rules screen, providing instant, one-click bulk expansion and collapse across every registered category.

---

🎨 Visual Layout & Split-Button Design

The header divides the screen width into two distinct interactive zones:

┌─────────────────────────────────────────────────────────────────────────────┐
│ ◄──────────────── Left Half ───────────────►◄────────────── Right Half ───► │
│               [ Expand All ]                               [ Collapse All ] │
│ ─────────────────────────────────────────────────────────────────────────── │
└─────────────────────────────────────────────────────────────────────────────┘

• Left Zone (mouseX < getX() + getWidth() / 2): Triggers expandAll.
• Right Zone (mouseX >= getX() + getWidth() / 2): Triggers collapseAll.
• Hover State: Highlights only the hovered half with a 0x22FFFFFF background tint and alters the text color to 0xFFFFFFAA.

⚙️ Technical Mechanics

1. Pinned Insertion at Index 0

During updateVisibleEntries() in AbstractGameRulesScreenRuleListMixin, the global actions header is injected before any category or rule entries:

if (!this.collapsible_game_rules$allEntries.isEmpty()) {
    this.addEntry(new GlobalActionsRuleEntry(
        () -> {
            List<String> allKeys = this.collapsible_game_rules$allEntries.stream()
                .filter(e -> e instanceof AbstractGameRulesScreen.CategoryRuleEntry)
                .map(e -> {
                    Component lbl = ((CategoryRuleEntryAccessor) e).collapsible_game_rules$getLabel();
                    if (lbl.getContents() instanceof TranslatableContents translatable) {
                        return translatable.getKey();
                    }
                    return lbl.getString();
                })
                .toList();
            GameRuleStateConfig.expandAll(allKeys);
            this.collapsible_game_rules$updateVisibleEntries();
        },
        () -> {
            GameRuleStateConfig.collapseAll();
            this.collapsible_game_rules$updateVisibleEntries();
        }
    ));
}

2. Category Key Extraction

To expand all categories, the stream pipeline extracts every category's unique identifier:

1. Filters entries to find CategoryRuleEntry instances.
2. Accesses the category label via CategoryRuleEntryAccessor.
3. If the label contains TranslatableContents, extracts the localization key (e.g. gamerule.category.spawning).
4. Falls back to raw literal strings if unlocalized.
5. Collects keys into an immutable Java 25 list (.toList()) and passes them to GameRuleStateConfig.expandAll(allKeys).

3. Click Dispatching Logic

In GlobalActionsRuleEntry.mouseClicked(MouseButtonEvent event, boolean doubleClick):

if (event.button() == 0 || event.button() == 1) {
    double mouseX = event.x();
    if (mouseX < this.getX() + this.getWidth() / 2.0) {
        this.expandAll.run();
    } else {
        this.collapseAll.run();
    }
    Minecraft.getInstance().getSoundManager().play(
        SimpleSoundInstance.forUI(SoundEvents.UI_BUTTON_CLICK, 1.0F)
    );
    return true;
}

🌐 Localization Keys

The action titles are fully localized via src/main/resources/assets/collapsiblegamerules/lang/en_us.json:

{
  "gui.collapsible-game-rules.expand_all": "Expand All",
  "gui.collapsible-game-rules.collapse_all": "Collapse All"
}
