创造模式物品栏的物品子组库

基础库

.detail-panel[hidden] { display: block !important; } .detail-tabs { display: none; } /* These three panels are rendered by the browser. */ [data-versions], [data-changelog-panel], [data-comments] { display: none; }

关于 Fractal

本仓库是 unascribed 所著 lib39/fractal 的分支，增加了对样式化子组的支持。在 unascribed 忙碌期间，我将负责维护此仓库。

Fractal 为创造模式菜单引入了物品子组功能。

为什么选择 Fractal？

Fractal 的子组非常紧凑，可为每个标签页添加最多 12 个子组
创建新的 ItemSubGroup 仅需一行代码，且无需改变将物品分配到组的方式。只需将 ItemSubGroup 传递给你的主物品组即可

限制

每个物品组超过 12 个子组虽然功能上可正常运作，但显示效果会不佳。
用于标签的极小的字体不支持完整 Unicode 字符。

示例

原版风格子组

创造模式标签页截图

public static final Identifier GROUP_ID = new Identifier("mymod", "main");

public static final ItemGroup MAIN = FabricItemGroup.builder()
		.icon(() -> new ItemStack(Blocks.REDSTONE_BLOCK))
		.entries((displayContext, entries) -> entries.add(Items.APPLE))
		.displayName(Text.translatable("mymod.1"))
		.noRenderedName()
		.build();

public static final ItemGroup EQUIPMENT = new ItemSubGroup.Builder(MAIN, Text.translatable("itemGroup.mymod.equipment")).entries((displayContext, entries) -> entries.add(Items.APPLE)).build();
public static final ItemGroup FUNCTIONAL = new ItemSubGroup.Builder(MAIN, Text.translatable("itemGroup.mymod.functional")).styled(STYLE).entries((displayContext, entries) -> entries.add(Items.BAKED_POTATO)).build();
public static final ItemGroup CUISINE = new ItemSubGroup.Builder(MAIN, Text.translatable("itemGroup.mymod.cuisine")).entries((displayContext, entries) -> entries.add(Items.CACTUS)).build();
public static final ItemGroup RESOURCES = new ItemSubGroup.Builder(MAIN, Text.translatable("itemGroup.mymod.resources")).styled(STYLE).entries((displayContext, entries) -> entries.add(Items.DANDELION)).build();

@Override
public void onInitialize() {
    Registry.register(Registries.ITEM_GROUP, GROUP_ID, MAIN);
}

应用自定义样式

你还可以通过提供自定义的背景、标签页、子标签页以及滚动条材质来为你的 ItemSubGroup 应用样式。甚至可以混合搭配！在此示例中，前两个 ItemSubGroup 通过提供随模组一同发布的材质文件来使用自定义样式。后两个标签页则使用原版样式。
