# 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.

  • 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.

  • Text elements support dynamic data and scaling
> dynamicType: score, death_cause, player_name – display real-time game data;
scale: scale text (e.g. "scale": 1.2).

  • Colors now support hex strings
> Use "0xAARRGGBB" or "0xRRGGBB" format (e.g. "color": "0xFFAA00").

  • Extended button actions
> Added resume_game, disconnect, open_link, respawn, exit_to_title.

  • Enhanced expression system
> Supports width, height, elementWidth, elementHeight and basic arithmetic.

## 🔧 Improvements
  • Fully adjustable layout
> Buttons and text can be placed anywhere; multi-layer background masks are supported.

  • Internal loading optimization
> Removed style cache, fixed link confirmation dialog invocation.

## 🐛 Fixes

  • Fixed open_link action not working.

  • Fixed hex color values causing invisible text (alpha channel auto-filled).

  • Fixed coordinate and matrix transform errors when scaling text.

  • Fixed the error that the resource package cannot be loaded.


## ⚠️ Notes
  • Colors must be strings with quotes, e.g. "color": "0xFFFFFF".

  • For score display, it is recommended to use two text elements: deathScreen.score (prefix) + dynamicType: "score" (number).

  • open_link action requires a "url" field.
