Changelog

v0.4.86-Dev.64 (Alpha)

注意 : 这是一个开发版，可能会有很多bug

New Features

• Changed the options screen
• Added PPT transition logic
• Added player entity display in the title screen

Bug Fixes

• Fixed incompatibility with owo-lib
• Fixed missing Mods list button

Architecture Refactor

• Widget component system: Refactored from a monolithic Element class to an interface-based Widget component architecture. Added widget/ package with 17 standalone Widget classes:
  • Basic: TextWidget, ImageWidget, ButtonWidget, BoxWidget
  • Container: ContainerWidget, ContentWidget, ButtonContentWidget
  • List: ListWidget, DynamicListWidget, PackListWidget
  • Interactive: SliderWidget, StringEditBoxWidget
  • Display: EntityDisplayWidget
  • Cycle: CycleButtonWidget, ArrowSwitchWidget, DropdownWidget, SelectorWidget
• Render context: Added context/ package (RenderContext, ScreenVariableRegistry, WidgetDimensionRegistry) for unified render state and variable management
• Property separation: data/props/ package decouples style, text, layout, and animation properties from the old Element into independent records (StyleProps, TextProps, LayoutProps, SliderProps, CycleButtonProps, etc.)
• Factory pattern: Added WidgetFactory for unified JSON → Widget construction

New Features

• Entity display: Added EntityDisplayWidget with FakePlayer/FakeLevel, enabling player entity model rendering within UIs
• Dynamic lists: Added DynamicListWidget, supporting dynamic list loading from data sources (server list, world saves, Realms, resource packs)
• Data sources: Added data/source/ package with ServerListDataSource, WorldSaveDataSource, RealmsDataSource, PackDataSource
• Animation system: Added AnimationStep record, supporting per-frame text animation configuration
• Cycle/selection controls: Added four interactive control types: arrow_switch, cycle, dropdown, selector

Mixin Changes

• Removed GuiGraphicsMixin (old alpha blending override)
• Added LivingEntityRendererMixin to fix name display issues when rendering FakePlayer entities

Removed Legacy Code

• Removed Element.java — old monolithic element class
• Removed ElementRenderer.java — old centralized renderer
• Removed InteractionHandler.java — old centralized interaction handler
• Removed ScreenBuilder.java — old screen builder
• Removed ButtonStyle.java / ButtonStyleData.java — old button style classes
• Removed SizeDeserializer.java — old size deserializer

Assets

• Screen configs: Added 6 new screens (screen, options_screen, play_selection_screen, resource_packs_screen, mouse_settings_screen, font_options_screen)
• Widget JSONs: Expanded from simple button configs to a comprehensive Widget configuration system, covering all settings categories: accessibility, chat, controls, general, skin, sounds, video
• Textures: Significantly expanded button textures including titlemenu series, select series, world series, options icons, slider components, etc.; legacy textures moved to options/old/
• Language files: 22 language files trimmed and aligned to zh_cn.json as the baseline

• only for 1.21.1, because there is no such issue in 26.1
• fixed a issue that GuiGraphics was incompatible with the Alpha channel.

SIRIUS Ui Changelog: v0.3.2 → v0.3.7

🎉 New Features

1. New Background Type: PPT Slideshow (type: "ppt")

• Replaces the removed experimental GIF background with a robust multi-image slideshow.
• Images can be organised into groups, each with an independent playCount (-1 for infinite loop).
• Customise group playback order with playGroups; use playAfter to make a specific group loop forever (e.g. intro sequence followed by a looping main background).
• Each slide can have its own time (milliseconds); a global defaultTime is used when a slide omits it.

2. Screen Registration (register.json)

• File path: assets/minecraft/alanht/register.json
• Maps custom screen IDs to JSON layout files, enabling the mod to recognise and open completely new screens.

3. Internationalisation

• The wiki now supports Simplified Chinese, Traditional Chinese, and English, with dark/light theme switching.

🔧 Changes & Improvements

1. JSON Key Changes ⚠️ (Resource Pack Update Required)

Old (v0.3.2)	New (v0.3.7)	Notes
type: "logo"	type: "image"	Element type for static images renamed to image.
type: "cycle" (experimental)	(removed)	Cycle button element temporarily removed.
type: "list" (experimental)	(removed)	Scrollable list element temporarily removed.
type: "catalog" (experimental)	(removed)	Catalog navigation element temporarily removed.
type: "slider" (experimental)	type: "slider" (still experimental)	Slider element retained but remains experimental.

Note: Button styles (button_styles/*.json) have not changed between v0.3.2 and v0.3.7.

2. Expression Variable Renames ⚠️

Old Variable (v0.3.2)	New Variable (v0.3.7+)
width	screen.width
height	screen.height
elementWidth	this.width
elementHeight	this.height
(none)	parent.width, parent.height, containerWidth, containerHeight

3. Recommended Resource Pack Structure Changed

• Old structure used paths like assets/minecraft/screens/.
• New standard path is assets/sirius_ui/screens/. Texture paths must include the full namespace (e.g. sirius_ui:textures/...).

4. Action Enhancements

• disconnect and exit_to_title now share a unified flow.
• respawn logic is more robust.

5. Documentation Overhaul

• The wiki has been restructured from a single page into modular, multi-page documentation with a sidebar.
• A Troubleshooting chapter has been added.

---

❌ Removals & Deprecations

• type: "gif" background has been removed. Migrate all GIF backgrounds to type: "ppt".
• The old logo element type is deprecated; use image instead.
• Experimental elements cycle, list, catalog have been temporarily removed. They are not available in v0.3.7.
• Legacy paths like assets/minecraft/screens/ are no longer recommended.

📋 Upgrade Checklist (v0.3.2 → v0.3.7)

1. Rename all "type": "logo" elements to "type": "image".
2. Replace all "type": "gif" backgrounds with "type": "ppt" using the new slideshow syntax.
3. Remove any usage of cycle, list, and catalog elements – they are not supported in this version.
4. Update all coordinate expressions with the new variable names:
   • width → screen.width
   • height → screen.height
   • elementWidth → this.width
   • elementHeight → this.height
5. If using register.json, ensure paths point to the new namespaces (e.g. sirius_ui:screens/...).
6. Slider configurations (type: "slider") can generally remain, but be aware the feature is still experimental and may change in the future.
7. Verify compatibility with the updated ScreenRegistry.
