* fix(config): load config on demand in get/set instead of asserting
* feat(chat): implement in-game chat box with UTF-8 support
- Add ChatMessage struct and ChatBox widget for displaying and sending messages
- Introduce split_utf8() in text_tools for splitting UTF-8 strings by character count
- Add TimeTools utility (get_time_ticks) for message timestamps
- Update TextField with start_typing/stop_typing methods and set_typing()
- Integrate text input handling in WorldScene and WorldUIManager for chat
- Add utf8cpp library for robust UTF-8 validation and processing
- Add ChatBox rendering and input logic (src/ui/chat_box.cpp)
- Register ChatBox source in CMakeLists.txt
- Fix Renderer::render_lable to skip rendering if VAO is null
- Update credits to include utf8cpp library
* fix(ui): correct chat box layout with dynamic height and bottom anchor
* feat(chat): implement client-server chat messaging
Add protobuf definition for ChatMsg, new packet ID CHAT_MSG (4001), and
handle sending/receiving chat messages on both client and server side.
Wire up UI components (ChatBox, TextField) to allow message input and
display, including a message queue in ClientWorld for thread-safe
processing. Also add default initialization for ChatMessage::time.
* feat(chat): distinguish between send and cancel in chat input
* feat(ui): add background to Label widget and refactor debug overlay
* refactor(ui): decouple ChatBox from image dependencies, allow custom TextField backgrounds
TextField's background is now a generic `Widget` pointer, enabling use of any widget (e.g., `Rect`, `Image`) as background. `ChatBox` no longer creates its own `TextField`; it accepts one via `set_text_field`. Removed `set_d_image` and `set_default_image` in favor of `set_background`. Added a shared default image constant in `default_image.hpp`. Updated `host_game_ui.cpp`, `join_game_ui.cpp`, and `world_ui_manager.cpp` to construct backgrounds accordingly.
* refactor(ui): move width, height, and fill properties to base Widget
Consolidate width, height, and fill (fill_parent, fill_width, fill_height) into the base Widget class. Replace per-widget set_fill(bool) with set_fill_parent(bool), set_fill_width(bool), and set_fill_height(bool).
* refactor(ui): generalize Label background, add ChatBox width method
* feat(chat): implement message expiration after 5 seconds
* feat(ui): add word wrap for chat messages with font width measurement
* feat(audio): implement voice chat using Opus codec
Add voice chat support with Opus encoding/decoding, push-to-talk (V key), and new audio recording infrastructure.
* feat(audio): implement voice chat with Opus codec and streaming audio source
Add AudioStreamSource for continuous PCM playback. Refactor voice send/receive to encode with Opus and stream to a dedicated source instead of per-frame sources. Enable voice transmission over network.
* feat(audio): add spatial voice source with underwater effects
Update voice source to support spatial positioning, low-pass filter, and reverb effect for underwater immersion. Adjust source pool size and low-pass filter parameter. Correct receive_voice parameter type.
* feat(settings): add player voice volume and voice input type options
- Add player voice volume slider and voice input type combo in settings UI.
- Add localization strings for player voice and voice input types.
- Add config overloads for const char* default values.
- Implement voice input types (PTT, always, off) in world scene.
- Refactor WorldScene member order and add load_config method.
- Update audio engine to use player voice volume.
- Downgrade some logging to debug.
* fix(event): delegate error UI events to each handler
Move error UI event check from top of handle_event into each individual
event handler (mouse_move, mouse_button, mouse_wheel, key, text_input).
Also flatten window resize dispatch: all sub-handlers are called regardless
of previous handler return values, and the method always returns false.
* feat(chat): add colored system messages for player join/exit
* chore(logging): reduce verbosity for audio loading and input events
* fix(settings): fix typo in config key "vloume"
* feat(ui): add microphone icon when recording voice
* feat(voice): limit voice message range to 48 units
* chore(logging): downgrade text input log level to debug
* feat(credits): add license identifiers and reorganize license files
* feat: add sensitive word filter for chat messages
Implement AC automaton-based filtering using a sensitive lexicon loaded from a JSON asset file. The filter is applied to both player names and chat messages before broadcasting, and can be toggled via the `sensitive_filter` config option.
* feat(server): add config option to disable voice chat
* fix: correct utf8 validation, add missing include, remove debug log
* build: add nlohmann/json library
* build(deps): add harfbuzz dependency
* feat(cmake): add guard to reject macOS builds
* feat(font): add HarfBuzz shaping and replace font with unifont
* feat(localization): add i18n support with en_US and zh_CN translations
Implement Localization class to load JSON translation files. Replace hardcoded strings in UI with translation keys and update sliders/combo buttons to use dynamic text.
* feat(localization): detect system locale for language default
* feat(settings): add language selection option with restart notification
* fix: use vckpg to add freetype on windows
