     5→# Anchor Engine Overview
     6→
     7→Anchor is a 2D game engine for solo indie developers. It combines a C core with Lua for game logic. The engine handles rendering, physics, audio, and input while the framework provides high-level abstractions for building games quickly.
     8→
     9→---
    10→
    11→## Core Philosophy
    12→
    13→**Locality** — Everything about a game object lives in one place. No scattered configuration files, no registering components in separate systems. A class definition contains its properties, behaviors, children, and cleanup logic together.
    14→
    15→**No bureaucracy** — No imports, no dependency injection, no boilerplate. Resources are registered once and accessed globally. Things work without setup.
    16→
    17→**Lua** — A lightweight scripting language with simple syntax. Classes via the framework's object system, clean table-based data, easy to read and write.

    "text": "Excellent! Now I have enough information. Let me compile a comprehensive summary of the findings:\n\n## Comprehensive Exploration Summary: b2CustomFilterFcn Support in Anchor Engine\n\nBased on my thorough exploration, here's the complete picture of how to add b2CustomFilterFcn support to the Anchor engine:\n\n---\n\n### 1. SHAPE CREATION IN ANCHOR.C\n\n**File:** `E:/a327ex/Anchor/engine/src/anchor.c`\n\nAll shape creation functions follow the same pattern. Here's the full code for each:\n\n**l_physics_add_circle** (lines 5615-5668):\n```c\n// physics_add_circle(body, tag, radius, [opts])\nstatic int l_physics_add_circle(lua_State* L) {\n    if (!physics_initialized) {\n        return luaL_error(L, \"Physics not initialized\");\n    }\n\n    b2BodyId* body_id = (b2BodyId*)lua_touserdata(L, 1);\n    if (!body_id) return luaL_error(L, \"Invalid body\");\n\n    const char* tag_name = luaL_checkstring(L, 2);\n    PhysicsTag* tag = physics_tag_get_by_name(tag_name);\n    if (!tag) return luaL_error(L, \"Unknown physics tag: %s\", tag_name);\n\n    float radius = (float)luaL_checknumber(L, 3);\n\n    // Parse options table (4th argument, optional)\n    bool is_sensor = false;\n    float offset_x = 0, offset_y = 0;\n    if (lua_istable(L, 4)) {\n        lua_getfield(L, 4, \"sensor\");\n        if (!lua_isnil(L, -1)) is_sensor = lua_toboolean(L, -1);\n        lua_pop(L, 1);\n\n        lua_getfield(L, 4, \"offset_x\");\n        if (!lua_isnil(L, -1)) offset_x = (float)lua_tonumber(L, -1);\n        lua_pop(L, 1);\n\n        lua_getfield(L, 4, \"offset_y\");\n        if (!lua_isnil(L, -1)) offset_y = (float)lua_tonumber(L, -1);\n        lua_pop(L, 1);\n    }\n\n    // Create shape def\n    b2ShapeDef shape_def = b2DefaultShapeDef();\n    setup_shape_def_from_tag(&shape_def, tag, is_sensor);\n\n    // Create circle geometry (convert to meters)\n    b2Circle circle = {\n        .center = { offset_x / pixels_per_meter, offset_y / pixels_per_meter },\n        .radius = radius / pixels_per_meter\n    };\n\n    // Create shape\n    b2ShapeId shape_id = b2CreateCircleShape(*body_id, &shape_def, &circle);\n\n    // Store tag index in shape's user data for event lookup\n    int tag_index = (int)(tag - physics_tags);\n    b2Shape_SetUserData(shape_id, (void*)(uintptr_t)tag_index);\n\n    // Return shape ID as userdata\n    b2ShapeId* ud = (b2ShapeId*)lua_newuserdata(L, sizeof(b2ShapeId));\n    *ud = shape_id;\n    return 1;\n}\n```\n\n**l_physics_add_box** (lines 5670-5730) and **l_physics_add_capsule** (lines 5732-5792) and **l_physics_add_polygon** (lines 5796-5861) follow the exact same pattern:\n1. Parse body and tag\n2. Parse shape-specific geometry\n3. Create b2ShapeDef with b2DefaultShapeDef()\n4. Call setup_shape_def_from_tag() to populate filter/events\n5. Create the shape with b2CreateXxxShape()\n6. Store tag index in shape's user data via b2Shape_SetUserData()\n7. Return shape ID as Lua userdata\n\n**setup_shape_def_from_tag** (lines 5603-5613):\n```c\n// Helper to setup shape def from tag\nstatic void setup_shape_def_from_tag(b2ShapeDef* def, PhysicsTag* tag, bool is_sensor) {\n    def->filter.categoryBits = tag->category_bit;\n    def->filter.maskBits = tag->collision_mask | tag->sensor_mask;  // Include both for filtering\n    def->isSensor = is_sensor;\n\n    // Enable events based on tag configuration\n    def->enableSensorEvents = (tag->sensor_mask != 0);\n    def->enableContactEvents = (tag->collision_mask != 0);\n    def->enableHitEvents = (tag->hit_mask != 0);\n}\n```\n\n**Key location to add enableCustomFiltering:** In `setup_shape_def_from_tag()`, you would add:\n```c\ndef->enableCustomFiltering = (tag->custom_filter_enabled != 0);  // New field in PhysicsTag\n```\n\n---\n\n### 2. BOX2D CUSTOM FILTER TYPES\n\n**File:** `E:/a327ex/Anchor/engine/include/box2d/types.h`\n\n**b2CustomFilterFcn typedef** (line 1139):\n```c\n/// Return false if you want to disable the collision\n/// @see b2ShapeDef\n/// @warning Do not attempt to modify the world inside this callback\n/// @ingroup world\ntypedef bool b2CustomFilterFcn( b2ShapeId shapeIdA, b2ShapeId shapeIdB, void* context );\n```\n\n**b2ShapeDef struct** (lines 389-439):\n```c\ntypedef struct b2ShapeDef\n{\n    /// Use this to store application specific shape data.\n    void* userData;\n\n    /// The surface material for this shape.\n    b2SurfaceMaterial material;\n\n    /// The density, usually in kg/m^2.\n    float density;\n\n    /// Collision filtering data.\n    b2Filter filter;\n\n    /// Enable custom filtering. Only one of the two shapes needs to enable custom filtering. See b2WorldDef.\n    bool enableCustomFiltering;              // <-- THIS FIELD (line 406)\n\n    /// A sensor shape generates overlap events but never generates a collision response.\n    bool isSensor;\n\n    /// Enable sensor events for this shape. This applies to sensors and non-sensors. False by default, even for sensors.\n    bool enableSensorEvents;\n\n    /// Enable contact events for this shape. Only applies to kinematic and dynamic bodies. Ignored for sensors. False by default.\n    bool enableContactEvents;\n\n    /// Enable hit events for this shape. Only applies to kinematic and dynamic bodies. Ignored for sensors. False by default.\n    bool enableHitEvents;\n\n    /// Enable pre-solve contact events for this shape. Only applies to dynamic bodies. These are expensive\n    bool enablePreSolveEvents;\n\n    /// When shapes are created they will scan the environment for collision the next time step.\n    bool invokeContactCreation;\n\n    /// Should the body update the mass properties when this shape is created. Default is true.\n    bool updateBodyMass;\n\n    /// Used internally to detect a valid definition. DO NOT SET.\n    int internalValue;\n} b2ShapeDef;\n```\n\n**Box2D API for custom filter callback** (lines 128-129 in `box2d.h`):\n```c\n/// Register the custom filter callback. This is optional.\nB2_API void b2World_SetCustomFilterCallback( b2WorldId worldId, b2CustomFilterFcn* fcn, void* context );\n```\n\n---\n\n### 3. HOW USER DATA WORKS (TAG INDEX SYSTEM)\n\n**File:** `E:/a327ex/Anchor/engine/src/anchor.c`, lines 619-625:\n\n```c\n// Get tag index from shape's custom data (stored during shape creation)\nstatic int physics_get_shape_tag(b2ShapeId shape_id) {\n    if (!b2Shape_IsValid(shape_id)) return -1;\n    // We store tag index in shape's user data\n    uintptr_t tag_data = (uintptr_t)b2Shape_GetUserData(shape_id);\n    return (int)tag_data;\n}\n```\n\n**PhysicsTag structure** (lines 462-468):\n```c\ntypedef struct {\n    char name[MAX_TAG_NAME];\n    uint64_t category_bit;    // Single bit identifying this tag (1, 2, 4, 8, ...)\n    uint64_t collision_mask;  // Which tags this collides with (physical response)\n    uint64_t sensor_mask;     // Which tags trigger sensor events\n    uint64_t hit_mask;        // Which tags trigger hit events\n} PhysicsTag;\n```\n\n**In shape creation, the tag index is stored as:**\n```c\nint tag_index = (int)(tag - physics_tags);  // Pointer arithmetic to get array index\nb2Shape_SetUserData(shape_id, (void*)(uintptr_t)tag_index);\n```\n\nThis allows collision event handlers to retrieve which tags collided by getting the user data back and finding the tag in the `physics_tags[]` array.\n\n---\n\n### 4. EXISTING LUA CALLBACK PATTERN (COLLISION EVENTS)\n\n**File:** `E:/a327ex/Anchor/engine/src/anchor.c`\n\nThe engine uses a **buffered event system** rather than direct C-to-Lua callbacks during physics step:\n\n**Event structures** (lines 500-547):\n```c\n// Contact begin event (two shapes started touching)\ntypedef struct {\n    b2BodyId body_a;\n    b2BodyId body_b;\n    b2ShapeId shape_a;\n    b2ShapeId shape_b;\n    int tag_a;  // Tag index of shape_a\n    int tag_b;  // Tag index of shape_b\n    float point_x;      // Contact point (pixels)\n    float point_y;\n    float normal_x;     // Normal from A to B\n    float normal_y;\n} PhysicsContactBeginEvent;\n\n// Similar for ContactEnd, Hit, SensorBegin, SensorEnd\n```\n\n**Event buffers** (lines 560-573):\n```c\nstatic PhysicsContactBeginEvent contact_begin_events[MAX_PHYSICS_EVENTS];\nstatic int contact_begin_count = 0;\n\nstatic PhysicsContactEndEvent contact_end_events[MAX_PHYSICS_EVENTS];\nstatic int contact_end_count = 0;\n\nstatic PhysicsHitEvent hit_events[MAX_PHYSICS_EVENTS];\nstatic int hit_count = 0;\n\nstatic PhysicsSensorBeginEvent sensor_begin_events[MAX_PHYSICS_EVENTS];\nstatic int sensor_begin_count = 0;\n\nstatic PhysicsSensorEndEvent sensor_end_events[MAX_PHYSICS_EVENTS];\nstatic int sensor_end_count = 0;\n```\n\n**Event processing** (lines 627-708):\n```c\n// Process physics events after b2World_Step\n// Retrieves all events from Box2D and buffers them with tag info for Lua queries\nstatic void physics_process_events(void) {\n    if (!physics_initialized) return;\n\n    // Get contact events from Box2D\n    b2ContactEvents contact_events = b2World_GetContactEvents(physics_world);\n\n    // Process contact begin events\n    for (int i = 0; i < contact_events.beginCount && contact_begin_count < MAX_PHYSICS_EVENTS; i++) {\n        b2ContactBeginTouchEvent* e = &contact_events.beginEvents[i];\n        if (!b2Shape_IsValid(e->shapeIdA) || !b2Shape_IsValid(e->shapeIdB)) continue;\n\n        int tag_a = physics_get_shape_tag(e->shapeIdA);\n        int tag_b = physics_get_shape_tag(e->shapeIdB);\n        if (tag_a < 0 || tag_b < 0) continue;\n\n        PhysicsContactBeginEvent* ev = &contact_begin_events[contact_begin_count++];\n        ev->shape_a = e->shapeIdA;\n        ev->shape_b = e->shapeIdB;\n        ev->body_a = b2Shape_GetBody(e->shapeIdA);\n        ev->body_b = b2Shape_GetBody(e->shapeIdB);\n        ev->tag_a = tag_a;\n        ev->tag_b = tag_b;\n        // ... extract contact manifold data ...\n    }\n}\n```\n\n**Lua query functions** (lines 6384-6503):\n```c\n// physics_get_collision_begin(tag_a, tag_b) -> array of event tables\nstatic int l_physics_get_collision_begin(lua_State* L) {\n    const char* tag_a_name = luaL_checkstring(L, 1);\n    const char* tag_b_name = luaL_checkstring(L, 2);\n\n    int tag_a = physics_tag_find(tag_a_name);\n    int tag_b = physics_tag_find(tag_b_name);\n    if (tag_a < 0) return luaL_error(L, \"Unknown tag: %s\", tag_a_name);\n    if (tag_b < 0) return luaL_error(L, \"Unknown tag: %s\", tag_b_name);\n\n    lua_newtable(L);\n    int result_index = 1;\n\n    for (int i = 0; i < contact_begin_count; i++) {\n        PhysicsContactBeginEvent* e = &contact_begin_events[i];\n        if (tags_match(e->tag_a, e->tag_b, tag_a, tag_b)) {\n            lua_newtable(L);\n            \n            // Populate event table with all details\n            b2BodyId* body_a_ud = (b2BodyId*)lua_newuserdata(L, sizeof(b2BodyId));\n            *body_a_ud = e->body_a;\n            lua_setfield(L, -2, \"body_a\");\n            \n            // ... more fields ...\n            \n            lua_rawseti(L, -2, result_index++);\n        }\n    }\n    return 1;\n}\n```\n\n**Key insight:** The engine does NOT use direct C-to-Lua callbacks during physics step. Instead, it:\n1. Buffers all events during `physics_process_events()`\n2. Lua polls events via functions like `physics_get_collision_begin()`\n\nThis design avoids threading issues and allows flexible Lua-side filtering.\n\n---\n\n### 5. SHAPE USER DATA STRUCTURE\n\nThere is no separate `PhysicsUserData` struct. Instead, the engine stores the **tag index** directly as a uintptr_t:\n\n**Lines 5660-5662 (in l_physics_add_circle, same in all shape creation):**\n```c\n// Store tag index in shape's user data for event lookup\nint tag_index = (int)(tag - physics_tags);\nb2Shape_SetUserData(shape_id, (void*)(uintptr_t)tag_index);\n```\n\nThe tag index is later retrieved in `physics_get_shape_tag()` and used to look up the tag name in the `physics_tags[]` array for event processing.\n\n---\n\n### 6. FRAMEWORK WRAPPER (collider.lua)\n\n**File:** `E:/a327ex/Anchor/framework/anchor/collider.lua`\n\n**Full collider class (lines 1-195):**\n\n```lua\nrequire('anchor.object')\n\n--[[\n  Collider class - wraps a Box2D physics body.\n\n  A child object added to game objects.

`physics_create_body()` to create the body\n- Then calls shape functions like `physics_add_circle(self.body, self.tag, ...)` with an optional `opts` table\n- Shape functions return a shape handle (userdata)\n- Body gets registered in `an.colliders[self.id]` for easy lookup\n\n---\n\n### 7. PHYSICS INITIALIZATION\n\n**File:** `E:/a327ex/Anchor/engine/src/anchor.c`, lines 5359-5372:\n\n```c\nstatic int l_physics_init(lua_State* L) {\n    if (physics_initialized) {\n        return 0;  // Already initialized\n    }\n\n    b2WorldDef world_def = b2DefaultWorldDef();\n    world_def.gravity = (b2Vec2){0.0f, 10.0f};  // Default gravity (10 m/s\u00b2 down)\n    world_def.restitutionThreshold = 0.0f;  // Allow full restitution at any speed\n\n    physics_world = b2CreateWorld(&world_def);\n    physics_initialized = true;\n    printf(\"Physics initialized (Box2D)\\n\");\n    return 0;\n}\n```\n\n**This is where you would register the custom filter callback:**\n```c\nb2CustomFilterFcn* custom_filter = &my_custom_filter_function;\nb2World_SetCustomFilterCallback(physics_world, custom_filter, NULL);\n```\n\n---\n\n## Summary for Implementation\n\nTo add b2CustomFilterFcn support, you would:\n\n1. **Add field to PhysicsTag struct:**\n   ```c\n   uint64_t custom_filter_mask;  // Tags that use custom filtering\n   ```\n\n2. **Modify setup_shape_def_from_tag():**\n   ```c\n   def->enableCustomFiltering = (tag->custom_filter_mask != 0);\n   ```\n\n3. **Create a custom filter callback function:**\n   ```c\n   static bool physics_custom_filter(b2ShapeId shapeIdA, b2ShapeId shapeIdB, void* context) {\n       // Get tags from shape user data\n       int tag_a = physics_get_shape_tag(shapeIdA);\n       int tag_b = physics_get_shape_tag(shapeIdB);\n       \n       // Custom filtering logic here\n       // Return true to allow collision, false to reject\n   }\n   ```\n\n4. **Register callback in l_physics_init():**\n   ```c\n   b2World_SetCustomFilterCallback(physics_world, &physics_custom_filter, NULL);\n   ```\n\n5. **Optionally add Lua functions** to configure custom filtering per tag or globally\n\nThe architecture is very clean: tag indices stored in shape user data allow the callback to determine which tags are colliding and apply custom logic without direct access to Lua objects."

## Approved Plan:
# Plan: Add b2CustomFilterFcn Support to Anchor Engine

## Context

CD projectiles need to physically ignore their own team's CD weapon while still physically colliding with enemy weapons. The current tag-level collision filtering can't do per-object exceptions. Box2D 3 provides `b2CustomFilterFcn` — a per-pair callback that can reject individual contacts. We'll expose this to Lua via "filter groups."

## Design: Filter Groups

**Concept:** Any shape can be assigned a "filter group" integer. When Box2D checks a potential collision and both shapes have the **same non-zero filter group**, the custom filter callback returns `false` → no collision. Otherwise the collision proceeds normally.

**Usage in game:** CD projectiles from the player team and the player's CD weapon both get filter group `1`. Enemy CD projectiles and enemy CD weapon both get filter group `2`. Same group → no collision. Different groups → collision proceeds (parry works).

## Changes

### 1. Engine: `E:/a327ex/Anchor/engine/src/anchor.c`

**a) ShapeUserData struct + pool** (near line 468, after PhysicsTag)

Currently shape user data is just a tag index cast to `void*`. Change to a struct so we can store filter_group alongside tag_index:

```c
typedef struct {
    int tag_index;
    int filter_group;
