     5→# Anchor Engine Overview
     6→
     7→Anchor is a 2D game engine for solo indie developers. It combines a C core with YueScript (a language that compiles to 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→**YueScript** — A clean syntax that compiles to Lua. Classes, `@` for self-reference, significant whitespace, operator overloading. Pleasant to read and write.

User has answered your questions: "The current headless mode skips all rendering (no window, no OpenGL, no FBOs). For frame capture, we need actual rendering to happen. Two broad approaches:

**A) New "capture" mode** — Run the game normally with a window and OpenGL, but instead of displaying to screen, read back each frame's pixels via glReadPixels after the layer compositing step and save to PNG. The game would run at full speed (not real-time), stepping deterministically. This is simpler since all the rendering code already works.

**B) Offscreen rendering** — Create an OpenGL context without a visible window (or with a hidden window), render to an FBO at 480x270, and read back pixels. More elegant (no window flash) but requires ensuring SDL can create a hidden window with a valid GL context.

Which approach do you prefer?"="A: Visible window (Recommended)", "For sound logging: the game calls `an\sound_play` with name, volume, and pitch. We need to intercept these. Should I:

A) Add a C-level hook that logs every sound_play call to a Lua table when in capture mode
B) Wrap it in YueScript — replace/monkey-patch `an\sound_play` to both play (or not play) the sound AND log it

Option B is simpler and doesn't touch the engine. The logged data would be: {frame, sound_name, volume, pitch}. For the final video, we'd use ffmpeg to layer the actual .ogg sound files at the right timestamps with the right pitch/volume."="YueScript wrapper (Recommended)", "For the final video assembly with ffmpeg: a 120Hz physics step battle could produce thousands of frames. The game updates at 120Hz but renders at 60Hz. Should the capture save frames at 60fps (matching visual render rate) or 120fps (every physics step)?"="60fps (Recommended)", "How should this feature be invoked? The existing headless mode uses CLI args like `--headless --matchup=dagger,sword --seed=42`. I'm thinking a new mode like `--capture --matchup=dagger,sword --seed=42` that runs with rendering enabled, captures frames to a temp directory, then runs ffmpeg at the end. Does that work, or do you have a different invocation in mind?"="Yes, the flag, except I don't know if it should be called Capture Mode or something else, let's discuss this." user notes: Yes, the flag, except I don't know if it should be called Capture Mode or something else, let's discuss this.. You can now continue with the user's answers in mind.

User has answered your questions: "What should the mode/flag be called? Some options based on what it does (render a battle to video):"="--render". You can now continue with the user's answers in mind.

Entered plan mode. You should now focus on exploring the codebase and designing an implementation approach.

In plan mode, you should:

1. Thoroughly explore the codebase to understand existing patterns
2. Identify similar features and architectural approaches
3. Consider multiple approaches and their trade-offs
4. Use AskUserQuestion if you need to clarify the approach
5. Design a concrete implementation strategy
6. When ready, use ExitPlanMode to present your plan for approval

Remember: DO NOT write or edit any files yet. This is a read-only exploration and planning phase.

    "text": "Perfect! Now I have comprehensive information. Let me compile the findings into a clear report for the user.\n\n## Engine Exploration Report: \"Render Mode\" Feature for PNG Frame Capture\n\nI've thoroughly explored the Anchor engine codebase and gathered all the specific details you need for planning a render mode feature. Here are the findings organized by your requested areas:\n\n---\n\n### 1. Main Loop Timing & Deterministic Stepping\n\n**File:** `E:/a327ex/Anchor/engine/src/anchor.c`\n\n**Key Constants (Lines 94-96):**\n```c\n#define PHYSICS_RATE (1.0 / 120.0)  // 120 Hz physics/input timestep\n#define RENDER_RATE  (1.0 / 60.0)   // 60 Hz render cap (for chunky pixel movement)\n#define MAX_UPDATES 10              // Cap on fixed steps per frame (prevents spiral of death)\n```\n\n**Timing Variables (Lines 8228-8233):**\n```c\nstatic double physics_lag = 0.0;\nstatic double render_lag = 0.0;\nstatic Uint64 step = 0;\nstatic double game_time = 0.0;\nstatic Uint64 frame = 0;\n```\n\n**Main Loop Structure** (`main_loop_iteration()` at **line 8778**):\n- Reads real delta time from SDL performance counter (line 8779-8780)\n- Clamps and smooths delta time with VSync snapping and averaging (lines 8786-8827)\n- **Accumulates to `physics_lag` and `render_lag`** (lines 8830-8839)\n- **Fixed timestep loop:** `while (physics_lag >= PHYSICS_RATE)` advances one 120Hz physics step (line 8958)\n- **Fixed render check:** `if (render_lag >= RENDER_RATE)` triggers one 60Hz render frame (line 9010)\n\n**Desktop Main Loop** (lines 9376-9381):\n```c\n} else {\n    // Desktop: traditional blocking loop\n    while (running) {\n        main_loop_iteration();\n    }\n}\n```\n\n**Critical Insight for Deterministic Mode:** The engine **is already deterministic if you bypass the real-time delta time reading.** The accumulators `physics_lag` and `render_lag` control stepping. You could inject a fixed `dt` value (e.g., `1.0/60.0` per iteration) to make each iteration advance exactly one physics step + one render step. This would be much simpler than refactoring the entire loop.\n\n---\n\n### 2. CLI Argument Parsing\n\n**File:** `E:/a327ex/Anchor/engine/src/anchor.c`\n\n**CLI Argument Storage** (Lines 84-89):\n```c\n#define MAX_CLI_ARGS 32\n#define MAX_CLI_KEY 64\n#define MAX_CLI_VALUE 256\nstatic struct { char key[MAX_CLI_KEY]; char value[MAX_CLI_VALUE]; } cli_args[MAX_CLI_ARGS];\nstatic int cli_arg_count = 0;\n```\n\n**Parsing Logic** (Lines 9171-9208):\n- `--headless` flag sets `headless_mode = true` (line 9175-9177)\n- `--key=value` pairs are parsed and stored in `cli_args` array (lines 9178-9195)\n- Key extraction uses `strchr(arg, '=')` to split on `=` (line 9181)\n- If no `=`, defaults to value `\"true\"` (line 9193)\n\n**Lua Access** (`engine_get_args()` at **line 7815**):\n```c\nstatic int l_engine_get_args(lua_State* L) {\n    lua_newtable(L);\n    for (int i = 0; i < cli_arg_count; i++) {\n        lua_pushstring(L, cli_args[i].value);\n        lua_setfield(L, -2, cli_args[i].key);  // table[key] = value\n    }\n    return 1;\n}\n```\n\n**How to use from YueScript:**\n```lua\nlocal args = engine_get_args()\nif args.render_mode then\n  -- capture frames\nend\n```\n\n**Headless Mode Access** (Lines 7787-7803):\n```c\nstatic int l_engine_get_headless(lua_State* L) {\n    lua_pushboolean(L, headless_mode);\n    return 1;\n}\n```\n\n---\n\n### 3. Image Writing Capability (stb_image_write)\n\n**File:** `E:/a327ex/Anchor/engine/src/anchor.c`\n\n**Status: NOT INCLUDED**\n\nThe engine includes several stb libraries:\n- **Line 45-46:** `stb_image.h` (for loading)\n- **Line 48-49:** `stb_perlin.h` (for noise)\n- **Line 51-52:** `stb_vorbis.c` (for audio)\n\n**But NO `stb_image_write.h` is included.** This is a gap you'll need to fill. The good news: stb_image_write is a single-header library, so you can:\n1. Add `#define STB_IMAGE_WRITE_IMPLEMENTATION` before the include\n2. Include it at the top with the other stb headers\n3. Use `stbi_write_png(filename, width, height, channels, data, stride)` to write PNG files\n\nThe header should be added around **line 45-52** where the other stb includes live.\n\n---\n\n### 4. The `sound_play()` C Function Signature\n\n**File:** `E:/a327ex/Anchor/engine/src/anchor.c`, Lines 1293-1351\n\n```c\nstatic int sound_play(Sound* sound, float volume, float pitch) {\n    // Returns: slot index (0+) or -1 if no free slots\n```\n\n**Full Implementation (1293-1351):**\n- Takes `Sound*` pointer, `volume` (0-1 perceptual), `pitch` (1.0 = normal)\n- Finds a free slot in `playing_sounds[]` array\n- Initializes miniaudio decoder and sound object\n- Applies volume: `linear_to_perceptual(volume * sound_master_volume)` (line 1342)\n- Applies pitch: `pitch * audio_master_pitch` (line 1345)\n- Marks slot as in-use and starts playback\n- **Returns**: slot index (int) or -1 on failure\n\n**Lua Binding** (Lines 4933-4939):\n```c\nstatic int l_sound_play(lua_State* L) {\n    Sound* sound = (Sound*)lua_touserdata(L, 1);\n    float volume = (float)luaL_optnumber(L, 2, 1.0);\n    float pitch = (float)luaL_optnumber(L, 3, 1.0);\n    sound_play(sound, volume, pitch);\n    return 0;  // Returns nothing to Lua\n}\n\nstatic int l_sound_play_handle(lua_State* L) {\n    // Same as above but RETURNS the handle (encoded slot + generation)\n    int slot = sound_play(sound, volume, pitch);\n    lua_pushinteger(L, sound_handle_encode(slot, playing_sounds[slot].generation));\n    return 1;  // Returns handle to Lua\n}\n```\n\n**For a Monkey-Patch:** You'd need to intercept the Lua call and record when sounds are played. Since the C function doesn't return the slot to regular `sound_play()`, you'd use `sound_play_handle()` as the basis for your wrapper, or add a new engine function specifically for render mode.\n\n---\n\n### 5. Frame Capture Hook Point (glReadPixels)\n\n**File:** `E:/a327ex/Anchor/engine/src/anchor.c`\n\n**The Render Pipeline** (Lines 9041-9149):\n\n**PASS 1: Lua draw() executes (lines 9041-9060)**\n- Unbinds any active texture (line 9043)\n- Calls `lua_getglobal(L, \"draw\")` and executes it (lines 9046-9059)\n- At this point, all layers are rendered to their FBOs but nothing is composited to screen yet\n\n**PASS 2: Composite layers to screen (lines 9062-9149)**\n- `glBindFramebuffer(GL_FRAMEBUFFER, 0)` \u2014 **switches to default framebuffer** (line 9063)\n- Clears window to black (lines 9083-9085)\n- Sets up viewport and projection for game coordinates (lines 9087-9088)\n- Loops through `layer_draw_queue` (lines 9100-9118) or all layers (lines 9131-9142)\n- Each layer texture is bound and rendered as a full-screen quad (lines 9113-9117 or 9134-9138)\n- **After the compositing loop (line 9143), before `SDL_GL_SwapWindow()`** is the ideal hook point\n- `glBlendFuncSeparate` is reset to standard alpha blending (lines 9146-9147)\n- **`SDL_GL_SwapWindow(window)` swaps buffers (line 9149)**\n\n**Optimal Insertion Point for PNG Capture:**\n\nBetween **line 9143** (end of compositing) and **line 9149** (buffer swap):\n```c\n// After all compositing to FBO 0 (default framebuffer), before swap:\nif (should_capture_this_frame) {\n    // At this point, FBO 0 (default framebuffer) contains the composited frame\n    // glReadPixels reads from the currently bound read framebuffer\n    glReadPixels(0, 0, game_width, game_height, GL_RGBA, GL_UNSIGNED_BYTE, pixel_buffer);\n    // Write pixel_buffer to PNG via stbi_write_png()\n}\n\nSDL_GL_SwapWindow(window);\n```\n\n**Critical FBO State at This Point:**\n- `GL_FRAMEBUFFER` is **bound to 0** (the default/screen framebuffer) (line 9063)\n- All layer compositing has drawn to this framebuffer\n- The **viewport is set to the game area** within the window (line 9088: `game_width, game_height`)\n- You should read the **game_width \u00d7 game_height** region, not the full window\n\n**Layer Structure** (Lines 400-425):\n```c\ntypedef struct {\n    GLuint fbo;                   // Main FBO\n    GLuint color_texture;         // Main color render target\n    GLuint effect_fbo;            // Effect/shader ping-pong\n    GLuint effect_texture;        // Effect target\n    bool textures_swapped;        // Which buffer is current\n    // ... transform stack, command queue ...\n} Layer;\n```\n\n**Getting Texture from Layer** (Line 1692-1693):\n```c\nstatic GLuint layer_get_texture(Layer* layer) {\n    return layer->textures_swapped ? layer->effect_texture : layer->color_texture;\n}\n```\n\nThis shows layers are FBO-based with dual-buffer effects support.\n\n---\n\n## Summary & Actionable Insights\n\n| Aspect | Finding |\n|--------|---------|\n| **Determinism** | Engine is already fixed-timestep; just inject fixed `dt` (~1/60s) to make it deterministic. Accumulators handle the rest. |\n| **CLI Args** | Accessible via `engine_get_args()` Lua function; returns table `{key = value}`. |\n| **Image Writing** | **Not included**; need to add `stb_image_write.h` header and link. |\n| **Sound Interception** | `sound_play()` returns slot index; need to wrap `sound_play_handle()` for render mode tracking. |\n| **Frame Capture** | Insert `glReadPixels()` between line 9143\u20139149 in `main_loop_iteration()`. FBO 0 is bound; viewport is correctly set to game area. |\n| **Pixel Format** | Read as `GL_RGBA` + `GL_UNSIGNED_BYTE` (4 bytes per pixel, standard). |\n\nThe engine is well-structured for this feature. The main work is adding stb_image_write and creating a deterministic mode with frame capture hooks."

How are you capturing sound logs?

User has answered your questions: "The thrust weapon uses `an\sound_play_handle` which returns a handle, then later calls `sound_handle_set_pitch` to dynamically change the pitch over time. This is harder to capture in a sound log since the pitch changes frame-by-frame. Should we:

A) Log the initial play and ignore dynamic pitch changes (acceptable approximation — it's one weapon's thrust sound)
B) Also monkey-patch `sound_handle_set_pitch` and `sound_handle_set_volume` to track changes, then generate a more complex ffmpeg filter that changes pitch over time
C) Skip the monkey-patch approach and do sound capture at the C level instead"="Track handle changes too". You can now continue with the user's answers in mind.

The user doesn't want to proceed with this tool use. The tool use was rejected (eg. if it was a file edit, the new_string was NOT written to the file). To tell you how to proceed, the user said:
For the pitch sounds, isn't it easier to just create a sound file for that specific pitch progression instead of doing multiple segments? Like, take the original, modify it with ffmpeg with the pitch progression (whatever it happens to be), that's a new file. Do this for every different pitch progression in the battle, then just use those new ogg files directly.

User has answered your questions: "Does this piecewise approach work for you? Split the handle-based sound into ~10 time chunks, apply constant pitch per chunk, concatenate into a single new file. Then use that file as a simple one-shot in the final audio mix. The transitions between chunks would be imperceptible at 50ms granularity."="Piecewise chunks (Recommended)".

# stb_image_write.h - Complete File Contents

This is the complete raw file contents of stb_image_write v1.16, a public domain C library for writing image files (PNG, BMP, TGA, JPEG, HDR) to stdio or custom callbacks.

**Key characteristics:**

The library provides five main write functions for different formats, plus callback-based alternatives. As noted in the documentation: "This library is designed for source code compactness and simplicity, not optimal image file size or run-time performance."

**Core functions:**

- `stbi_write_png()` / `stbi_write_bmp()` / `stbi_write_tga()` / `stbi_write_jpg()` / `stbi_write_hdr()`
- Callback versions: `stbi_write_[format]_to_func()`
- `stbi_flip_vertically_on_write()` for vertical flipping

**Configuration options:**

- Custom memory allocation (STBIW_MALLOC, STBIW_FREE, STBIW_REALLOC)
- Custom zlib compression (STBIW_ZLIB_COMPRESS)
- PNG compression level control
- Windows UTF-8 filename support

**Licensing:**
Available under either the MIT License or public domain (Unlicense). Users choose their preferred license.

The implementation includes complete DEFLATE compression, Huffman coding, DCT transformation for JPEG, and CRC32 checksums for PNG validation.
