Extract player entity setup into a Player class
Moves the capsule/physics/renderable/PLAYER setup out of overworldscene.js's inline init() into assets/scripts/Player.js so the scene module just instantiates it.

 # Dusk — Claude Code rules
 ## File headers
 Every C, H, and JS file starts with:
 ```c
 /**
 * Copyright (c) 2026 Dominic Masters
 *
 * This software is released under the MIT License.
 * https://opensource.org/licenses/MIT
 */
 ```
 JS files use `//` comment style instead.
 ---
 ## C conventions
 ### Types
 Always use the project-defined aliases instead of bare C primitives:
 | Use       | Not          |
 |-----------|--------------|
 | `bool_t`  | `bool`       |
 | `int_t`   | `int`        |
 | `float_t` | `float`      |
 | `char_t`  | `char`       |
 Use `uint8_t`, `uint16_t`, `int32_t`, etc. for fixed-width integers.
 All struct and enum types end in `_t` (`animation_t`, `errorret_t`, …).
 ### Naming
 - **Functions** — snake_case, prefixed with their module:
  `assetLock()`, `entityPositionInit()`, `moduleAssetBatchCtor()`
 - **Struct fields** — camelCase: `keyframeCount`, `localPosition`
 - **Macros / constants** — UPPER_SNAKE_CASE:
  `ENTITY_ID_INVALID`, `ERROR_OK`, `COMPONENT_TYPE_COUNT`
 - **Files** — snake_case matching the primary type: `entityposition.c`,
  `moduleassetbatch.c`
 ### Header files (`.h`)
 - Use `#pragma once` — no include guards.
 - Declare every public function, `#define`, and `extern` global.
 - Write a JSDoc block (`/** … */`) above every declaration explaining
  purpose, `@param`s, and `@returns`.
 - Only include headers that the `.h` file itself strictly requires for
  the types it exposes. Move everything else to the `.c` file.
  Do not use forward declarations as a workaround — use the real
  include in the `.c` file instead.
 ### Implementation files (`.c`)
 - Contain function bodies only; no declarations.
 - Pull in whatever additional includes the implementation needs.
 - Do not use `static` or `inline` on **functions**. Every function,
  including internal helpers, must be declared in the matching `.h` and
  defined in the `.c` file. Internal helpers belong near the bottom of
  the `.c` file, not at the top with a `static` qualifier.
  `static` and `inline` on functions are only appropriate when the
  function body is written directly inside a `.h` file.
  `static` on **variables** (file-scope state) is fine and expected.
 ### Formatting
 - Hard-wrap all lines at **80 characters**.
 ### Error handling
 Return `errorret_t` from fallible functions. Use these macros:
 ```c
 errorOk();                    // return success
 errorThrow("msg %d", val);    // return failure with message
 errorChain(someCall());       // propagate failure, continue on success
 errorIsOk(ret) / errorIsNotOk(ret)  // test a result
 errorCatch(ret);              // handle + free an error
 ```
 Never return raw error codes or use `errno` for in-engine errors.
 ### Memory
 Use the project allocator — never raw `malloc`/`free`:
 ```c
 memoryAllocate(size)          // allocate
 memoryFree(ptr)               // free
 memoryZero(dest, size)        // zero a block
 memoryCopy(dest, src, size)   // copy
 ```
 ### Asserts
 Prefer specific assert macros over bare `assert()`:
 ```c
 assertNotNull(ptr, "msg");
 assertTrue(cond, "msg");
 assertFalse(cond, "msg");
 assertUnreachable("msg");
 assertIsMainThread("msg");
 ```
 ---
 ## Build system
 Each subdirectory has its own `CMakeLists.txt` that adds sources with:
 ```cmake
 target_sources(${DUSK_LIBRARY_TARGET_NAME}
  PUBLIC
    myfile.c
 )
 ```
 Never add source files to the root `CMakeLists.txt` directly.
 ---
 ## Platform support
 ### Targets
 Set `DUSK_TARGET_SYSTEM` at CMake configure time to select a platform:
 | `DUSK_TARGET_SYSTEM` | Macro defined     | Platform         |
 |----------------------|-------------------|------------------|
 | `linux`              | `DUSK_LINUX`      | Linux desktop    |
 | `knulli`             | `DUSK_KNULLI`     | Knulli (handheld)|
 | `psp`                | `DUSK_PSP`        | Sony PSP         |
 | `vita`               | `DUSK_VITA`       | PlayStation Vita |
 | `gamecube`           | `DUSK_GAMECUBE`   | Nintendo GameCube|
 | `wii`                | `DUSK_WII`        | Nintendo Wii     |
 ### Layer structure
 ```
 src/dusk/          core, platform-agnostic game logic
 src/duskgl/        OpenGL abstraction (Linux, Knulli, PSP, Vita)
 src/dusksdl2/      SDL2 window + input (Linux, Knulli, PSP, Vita)
 src/dusklinux/     Linux + Knulli platform impl
 src/duskpsp/       PSP platform impl
 src/duskvita/      Vita platform impl
 src/duskdolphin/   GameCube / Wii platform impl (no SDL2/OpenGL)
 ```
 Dolphin is the only target that bypasses SDL2 and OpenGL entirely —
 it uses native GameCube/Wii rendering and input APIs.
 ### Platform guards
 Use the compile-time macros for platform-specific code:
 ```c
 #ifdef DUSK_PSP
  // PSP-only path
 #elif defined(DUSK_GAMECUBE) || defined(DUSK_WII)
  // GameCube / Wii path
 #else
  // Generic / Linux fallback
 #endif
 ```
 Additional capability macros set per-target:
 `DUSK_SDL2`, `DUSK_OPENGL`, `DUSK_OPENGL_ES`, `DUSK_OPENGL_LEGACY`,
 `DUSK_INPUT_GAMEPAD`, `DUSK_INPUT_KEYBOARD`, `DUSK_INPUT_POINTER`,
 `DUSK_PLATFORM_ENDIAN_BIG` / `DUSK_PLATFORM_ENDIAN_LITTLE`.
 ### Abstraction pattern
 Platform-specific implementations are wired in via `#define` macros in
 each platform's `displayplatform.h` / `inputplatform.h` etc., which
 the core calls through. Functions that a platform does not support are
 simply left undefined — the core guards calls with `#ifdef`.
 ### Adding platform-specific code
 - Put it under `src/dusk<platform>/` in the matching subsystem folder.
 - Gate any core call-site with the appropriate `#ifdef DUSK_<PLATFORM>`
  or capability macro.
 - Keep the `src/dusk/` core free of platform ifdefs — delegate through
  the platform header macros instead.

 ## Adding a new asset loader type
 1. Add an enum value to `assetloadertype_t` (before `_COUNT`) in
   `src/dusk/asset/loader/assetloader.h`.
 2. Add fields to the input/loading/output unions in `assetloader.h`.
 3. Implement `assetXxxLoaderSync`, `assetXxxLoaderAsync`, and
   `assetXxxDispose` in a new `src/dusk/asset/loader/xxx/` directory.
 4. Register the three callbacks in `ASSET_LOADER_CALLBACKS[]` in
   `src/dusk/asset/loader/assetloader.c`.
 5. If user-facing, create a JS module (see below) and a `.d.ts` file.
 ---
 ## Adding a new entity component
 1. Create `src/dusk/entity/component/<category>/entityMyComp.h/.c` with
   struct `entityMyComp_t`, `entityMyCompInit()`, and optionally
   `entityMyCompDispose()`.
 2. Add the include to `src/dusk/entity/componentlist.h` header block.
 3. Add a row to `src/dusk/entity/componentlist.h`:
   ```c
   X(MYCOMP, entityMyComp_t, myComp, entityMyCompInit, NULL, NULL)
   ```
   This auto-generates the enum, union field, and definition entry.
 4. If JS-facing, create the script module and `.d.ts` (see below).
 ---
 ## Adding a new script (JS) module
 1. Create `src/dusk/script/module/<category>/moduleMyMod.h/.c`.
   - Declare `extern scriptproto_t MODULE_MYMOD_PROTO;` in the header.
   - Use `moduleBaseFunction(name)` to define JS-callable functions.
   - Register props/funcs in `moduleMyModInit()` with
     `scriptProtoDefineProp` / `scriptProtoDefineFunc` /
     `scriptProtoDefineStaticFunc`.
 2. `#include` the header in
   `src/dusk/script/module/modulelist.c` and call
   `moduleMyModInit()` in `moduleListInit()` (and `Dispose` in
   `moduleListDispose()`).
 3. For component modules also register in
   `src/dusk/script/module/entity/component/modulecomponentlist.c`
   so `entity.add()` returns the typed wrapper.
 4. Create `types/<category>/mymod.d.ts` and add a
   `/// <reference path="..." />` line to `types/index.d.ts`.
 ---
 ## Script module type declarations
 Whenever a `src/dusk/script/module/**/*.c` file is created or modified,
 check whether the corresponding `types/**/*.d.ts` needs updating and
 apply any changes before finishing the task.
 ---
 ## JavaScript (asset scripts)
 - Use `var` for module-level state; `const` for values that never
  change.
 - Always use semicolons.
 - Scene objects are plain objects (`var scene = {}`) with assigned
  methods.
 - Export via `module.exports = scene`.
 - Async scene init should use `async function` and `await`.
 ---
 ## Coding style
 ### ASCII only
 Source files (`.c`, `.h`, `.js`) must contain only ASCII characters (U+0000–U+007F).
 Non-ASCII characters are banned even in comments and string literals.
 Use ASCII-only substitutes instead:
 - `--` or `-` instead of `—` (em dash)
 - `->` instead of `→` (arrow)
 - `x` or `*` instead of `×` (multiplication)
 Only non-script asset files (e.g. `.po` locale files) may contain non-ASCII text.
 ### Indentation
 2 spaces. No tabs.
 ### Keyword and operator spacing
 No space between a keyword or function name and its opening parenthesis:
 ```c
 if(!ptr) return;
 for(uint8_t i = 0; i < count; i++) {
 while(entry->state != DONE) {
 switch(type) {
 sizeof(assetbatch_t)
 memoryZero(ptr, size)
 ```
 Spaces around all binary operators and after every comma:
 ```c
 pos->flags |= ENTITY_POSITION_FLAG_WORLD_DIRTY;
 (size_t)end - (size_t)start
 foo(a, b, c)
 ```
 ### Braces
 Opening brace on the **same line** as the statement (K&R style) for all
 constructs — functions, `if`, `else`, `for`, `while`, `switch`:
 ```c
 void assetEntryLock(assetentry_t *entry) {
  ...
 }
 if(dirty) {
  ...
 } else {
  ...
 }
 ```
 ### Guard returns
 Short guards go on one line with no braces:
 ```c
 if(!ptr) return;
 if(!b || !b->batch) return jerry_undefined();
 if(!(flags & DIRTY)) return;
 ```
 ### Blank lines
 - One blank line between functions; no blank line at the start or end of
  a function body.
 - One blank line between logical blocks inside a function body.
 - No trailing blank lines at the end of a file.
 ### Pointer placement
 `*` is attached to the variable name, not the type:
 ```c
 assetentry_t *entry
 const char_t *name
 void *ptr
 uint8_t *d = (uint8_t *)dest;
 ```
 ### Casts
 Space between cast and operand:
 ```c
 (assetbatch_t *)user
 (uint8_t *)dest
 (textureformat_t)v
 ```
 ### Return
 No parentheses around the return value:
 ```c
 return ptr;
 return MEMORY_POINTERS_IN_USE;
 ```
 ### switch / case
 `case` indented 2 spaces from `switch`; body indented 2 more from `case`:
 ```c
 switch(type) {
  case ASSET_LOADER_TYPE_TEXTURE:
    descs[i].input.texture = (textureformat_t)v;
    break;
  default:
    break;
 }
 ```
 ### Multi-line function signatures
 When parameters don't fit on one line, put each on its own line indented
 2 spaces; the closing `) {` (definition) or `);` (declaration) goes on
 its own line at column 0:
 ```c
 void assetEntryInit(
  assetentry_t *entry,
  const char_t *name,
  const assetloadertype_t type,
  assetloaderinput_t *input
 ) {
 errorret_t memoryCompare(
  const void *a,
  const void *b,
  const size_t size
 );
 ```
 ### Structs and enums
 Anonymous inner struct or enum with a `typedef`, `_t` suffix, closing
 brace and name on the same line:
 ```c
 typedef struct {
  errorcode_t code;
  char_t *message;
 } errorstate_t;
 typedef enum {
  ASSET_LOADER_TYPE_NULL,
  ASSET_LOADER_TYPE_COUNT
 } assetloadertype_t;
 ```
 ### Designated initialisers
 Spaces inside braces; `.field = value`:
 ```c
 jsassetentry_t e = { .entry = entry };
 assetbatchloadedpend_t init = { .batch = batch };
 ```
 ### Ternary operator
 Spaces around `?` and `:`:
 ```c
 const float val = psx > 0.0f ? pt[0][0] / psx : 0.0f;
 ```
 ### const placement
 `const` before the type, `*` attached to the variable:
 ```c
 const char_t *name
 const void *src
 const size_t size
 ```
 ### Comments in `.c` files
 - Do not use section dividers (`/* ---- ... ---- */`). Just let the
  functions follow one another with a single blank line between them.
 - Multi-line explanatory comments inside function bodies use `//` lines:
  ```c
  // Script modules are freed; orphaned JS wrapper objects now get GC'd
  // so their finalizers fire before assetDispose() checks ref counts.
  jerry_heap_gc(JERRY_GC_PRESSURE_HIGH);
  ```
 - Do not use `/* */` for inline or inline-block comments inside `.c`
  function bodies.
 ### Comments in `.h` files
 Every public declaration gets a Javadoc block (`/** … */`) with
 `@param` and `@returns` where relevant. Keep it on the lines immediately
 above the declaration with no blank line in between.
 ---
 ## Color system
 Colors are defined in `src/dusk/display/color.csv` and code-generated
 into a `color.h` header by `tools/color/csv/__main__.py`.
 Each row in the CSV has `name,r,g,b,a` with channel values in `[0.0, 1.0]`.
 The script emits four `#define` variants per color plus a bare alias:
 ```
 COLOR_<NAME>_4B   color4b(r8, g8, b8, a8)   // default alias target
 COLOR_<NAME>_3B   color3b(r8, g8, b8)
 COLOR_<NAME>_3F   color3f(rf, gf, bf)
 COLOR_<NAME>_4F   color4f(rf, gf, bf, af)
 COLOR_<NAME>      COLOR_<NAME>_4B
 ```
 `color_t` is `color4b_t` (four `uint8_t` channels).
 To add a new color, append a row to `color.csv` and rebuild — do not
 hand-edit the generated header.
 ---
 ## Tests
 - Tests live in `test/` mirroring `src/dusk/` structure.
 - Use cmocka; include `dusktest.h`.
 - Test functions: `static void test_something(void **state)`.
 - After each test, assert `memoryGetAllocatedCount() == 0` to catch
  leaks.
 - Build with `-DDUSK_BUILD_TESTS=ON`.

YourWishes	42cb84b610	Extract player entity setup into a Player class Moves the capsule/physics/renderable/PLAYER setup out of overworldscene.js's inline init() into assets/scripts/Player.js so the scene module just instantiates it.	2026-08-02 21:06:31 -05:00
YourWishes	f8607d114c	Add UDP socket client/server multiplayer protocol Implements the multiplayer transport layer from ROADMAP.md: UUID-based client identity, a reliable-packet channel over UDP, handshake/ack/ ping/disconnect/player-joined/player-left/player-state packet types, and split online (networked) vs offline (in-process singleplayer) server modes wired into the engine's update/dispose loop.	2026-08-02 21:06:23 -05:00
YourWishes	56230dd340	Fix ref-count underflow, PSP timezone units, thread restart race, color codegen - util/ref.c: refUnlock's assert(count >= 0) on an unsigned count was tautological, so a double-unlock silently underflowed to UINT32_MAX instead of asserting. Now asserts count > 0 before decrementing. - duskpsp/time/timepsp.c: timeGetRealTimeZonePSP returned hours while every other platform (and timeepoch.c's math) expects seconds. - thread.c: threadHandler reset threadId outside the mutex, after signaling STOPPED, letting a caller's immediate threadStart() race threadStartRequest()'s "thread id not 0" assert. threadId is now reset inside the same locked section. - tools/color.py: whole-number CSV channels (0, 1) produced invalid C float literals (0f, 1f) for the generated COLOR_*_3F/_4F macros. Route through float() so they always stringify with a decimal point. Also adds .claude/code-check.md: a full review pass over every subsystem in src/dusk/, with the above (plus several other findings not yet acted on) written up in detail.

YourWishes	8f8fa8f8d1	Scene.set() JS lifecycle, UI sprite caching, emulator test scripts - Add Scene.set(module) so JerryScript can switch scenes via require()'d {init, update, dispose} modules; wire it into engineUpdate() and rework overworldscene.js/init.js to the new shape. - Fix scriptManagerExecFile() never pushing its own file's directory onto the require() dir stack, breaking relative require() calls from a top-level entry script (e.g. init.js -> ./overworldscene.js). - Cache sprite geometry across frames for uislider/uitab/uiframe (dialogs/textbox/settings) and give uitextbox a per-page glyph cache instead of one spriteBatchBuffer call per visible character. uiconsole drops its alloc/free vertex buffer for a fixed-size one. uifps skips rebuilding its label when the text hasn't changed. - Add PSP_OPTIMIZATION_PLAN.md and a handful of UI/spritebatch unit tests covering the new caching logic. - Add Dolphin/PPSSPP emulator smoke-test scripts (+ Docker variants and CI jobs) for GameCube/Wii/PSP.

YourWishes	e61914bad4	Finish JerryScript Entity/Scene wiring; remove JSON serialize/deserialize Register Entity, the generic Component wrapper, and Scene as JerryScript classes (modulelist.c ties them together, plus their .d.ts stubs), so scenes/entities can be built from script going forward instead of the JSON scene format. With scripting now the intended authoring path, drop the JSON serialize/deserialize machinery entirely: componentdefinition_t's serialize/deserialize callbacks, every component's Serialize/ Deserialize function, entitySerialize/entityDeserialize, sceneSerialize/sceneDeserialize, and the "prefabs/<name>.json"/ "scenes/<name>.json" asset fallback in entityPrefabResolveAndApply/ scenePrefabResolveAndApply (C-coded prefabs only now). physicsshape.c and its test are removed outright since they only existed for this. game.c's test scene now comes from the existing overworldSceneCreate() C builder instead of loading the now-deleted assets/scenes/test.json.

YourWishes	015d90519f	WIP: start JerryScript integration (core engine + Component wrapper) Ports the core scripting engine (scriptmanager, scriptproto, modulebase, moduleplatform) and a generic Component JS wrapper from the old we-ball branch, adapted to the current entitymanager_t/multi-scene architecture. Not yet buildable: moduleentity.c, modulescene, modulelist.h/.c, and the CMakeLists.txt for the new module subdirectories are still missing, and engine.c isn't wired up yet.
