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)

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

2. Expression Variable Renames ⚠️

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.
