# sdl-bgfx-imgui-starter
The idea behind this repo is for it to be used as a minimal starting point for development of a game, demo or prototype.
It utilizes [SDL2](https://www.libsdl.org/index.php) for the windowing system, [bgfx](https://github.com/bkaradzic/bgfx) (by [@bkaradzic](https://twitter.com/bkaradzic)) for the graphics library and [Dear ImGui](https://github.com/ocornut/imgui) (by [@ocornut](https://twitter.com/ocornut)) for the user interface.
The code in `main.cpp` is derived from two excellent `bgfx` tutorials ([hello-bgfx](https://dev.to/pperon/hello-bgfx-4dka) by [Phil Peron](https://twitter.com/pperon) and [bgfx-ubuntu](https://www.sandeepnambiar.com/getting-started-with-bgfx/) by [Sandeep Nambiar](https://twitter.com/_sandeepnambiar)). I highly recommend checking them out.
This repo does not directly include any of these dependencies. Instead, CMake is used to download and install them so this project can use them. This is handled through the use of a _superbuild_.
## Prerequisites
To begin with create a directory to hold the repo:
```bat
mkdir sdl-bgfx-imgui-starter
cd sdl-bgfx-imgui-starter
```
Then clone the repo:
```bash
git clone https://github.com/pr0g/sdl-bgfx-imgui-starter.git .
```
This project comes with a _superbuild_ CMake script which will build all third party dependencies and the main application in one step. The third party dependencies are built and installed to a separate build folder in the third party directory. To achieve this CMake must be installed on your system (the repo has most recently been tested with CMake version `3.24`).
> __Note__: It is possible to build the third party dependencies separately, but the configure scripts described below now default to use `-DSUPERBUILD=ON` (as this is the simplest and most common workflow). If you do wish to build the third party dependencies separately, please see the third party [__README__](third-party/README.md) for full instructions on how to do this.
>
> __Note__: When building the dependencies, the libraries are by default self contained in the repo and are not installed to the system.
## Build Instructions
### All
Shaders for `bgfx` must be compiled to be loaded by the application (the starter has an incredibly simple shader supporting vertex colours). See `compile-shaders-<platform>.sh/bat` for details. `shaderc` is built as part of `bgfx` when first building the repo and is used to compile the shaders.
> __Note__: A number of `configure-<generator>.bat/sh` files are provided to run the CMake configure commands. `Ninja` is preferred as it's consistent across _macOS_, _Linux_ and _Windows_ (and it's very fast), any generator should work though. For example there's a `configure-vs-19/22.bat` for generating a Visual Studio 2019 or 2022 solution.
### Windows
- Run `configure-vs-19.bat`, `configure-vs-22.bat` or `configure-ninja.bat` located in the root directory to generate the build files required for the project.
- Run `cmake --build build\debug-ninja` and/or `cmake --build build\release-ninja` to compile the project using Ninja or `cmake --build build\vs<year> --config Debug` and/or `cmake --build build\vs<year> --config Release` if using the Visual Studio generator.
- Run `compile-shaders-win.bat` located in the root directory to build the shaders.
- Launch the application by running `build\debug-ninja\sdl-bgfx-imgui-starter.exe` or `build\release-ninja\sdl-bgfx-imgui-starter.exe` if using Ninja or `build\vs<year>\Debug\sdl-bgfx-imgui-starter.exe` or `build\vs<year>\Release\sdl-bgfx-imgui-starter.exe` if using Visual Studio.
### macOS
- Run `./configure-make.sh` or `./configure-ninja.sh` located in the root directory to generate the build files required for the project (prefer Ninja if possible as it's much faster).
- Run `cmake --build build/debug-<generator>` and/or `cmake --build build/release-<generator>` to compile the project.
- Run `./compile-shaders-macos.sh` located in the root directory to build the shaders.
- Launch the application by running `./build/debug-<generator>/sdl-bgfx-imgui-starter` or `./build/release-<generator>/sdl-bgfx-imgui-starter`.
### Linux
- Check the [prerequisites](third-party/README.md#linux) when first starting out on Linux to ensure you have all the fundamentals (e.g. X11, OpenGL, Ninja etc...).
- Run `./configure-make.sh` or `./configure-ninja.sh` located in the root directory to generate the build files required for the project (prefer Ninja if possible as it's much faster).
- Run `cmake --build build/debug-<generator>` and/or `cmake --build build/release-<generator>` to compile the project.
- Run `./compile-shaders-linux.sh` located in the root directory to build the shaders.
- Launch the application by running `./build/debug-<generator>/sdl-bgfx-imgui-starter` or `./build/release-<generator>/sdl-bgfx-imgui-starter`.
### Emscripten (Windows/macOS/Linux)
> __Note__: Emscripten is built in a separate build folder called `embuild`, not `build`. This is to prevent Emscripten from overwriting native builds when built separately.
>
> __Note__: On Windows it may be necessary to run the command-line/terminal as Administrator when building Emscripten.
- Ensure you have [Python](https://www.python.org/downloads) installed on your system.
- Follow the install steps to setup Emscripten [here](https://emscripten.org/docs/getting_started/downloads.html) (This is required to be able to use the `emcmake` command in the various configure scripts).
- Run `./configure-emscripten.<bat/sh>` from the root directory.
- Ensure `emsdk_env.bat` or `source ./emsdk_env.sh` have been run before attempting this so `emcmake` is added to the path (see Emscripten instructions above for more details).
- Run `./compile-shaders-emscripten.<bat/sh>` located in the root directory. (_Note: In order to invoke_ `shaderc`, _the third party dependencies (specifically_ `bgfx`_) will have to have been built for the target platform as well as Emscripten, so the shaders can be compiled_). The build step for Emscripten copies the built shaders to the build folder (`embuild`), so compiling the shaders should happen before the main Emscripten build.
- Run `cmake --build embuild/debug-emscripten` and/or `cmake --build embuild/release-emscripten`.
- Start a local server (the easiest way to do this is with `python3 -m http.server`).
- Go to `localhost:8000` in a browser and open `embuild/<debug/release>-emscripten/sdl-bgfx-imgui-starter.html`.
## Resources
While getting this project setup I discovered a number of excellent resources. I'd highly recommend checking them out to learn more about `bgfx` and `Dear ImGui`.
- [bgfx](https://github.com/bkaradzic/bgfx) - `bgfx` main repo.
- [bgfx docs](https://bkaradzic.github.io/bgfx/index.html) - extensive docs covering much of `bgfx`'s API.
- [bkaradzic/bgfx.cmake](https://github.com/bkaradzic/bgfx.cmake) (originally [widberg/bgfx.cmake](https://github.com/widberg/bgfx.cmake)) - a complimentary repo to add CMake support to `bgfx` (used by this repo).
- [hello-bgfx (tutorial)](https://dev.to/pperon/hello-bgfx-4dka) - a great intro to `bgfx` and covers most of the code in the `main.cpp` of this repo.
- [bgfx-ubuntu(tutorial)](https://www.sandeepnambiar.com/getting-started-with-bgfx/) - another great tutorial on `bgfx` (showing how to get setup on Ubuntu).
- [minimal-bgfx](https://github.com/jpcy/bgfx-minimal-example) - a similar repo to this one only using `premake` and git submodules instead of CMake and with no `Dear ImGui`.
- [dear-imgui](https://github.com/ocornut/imgui) - `Dear ImGui` main repo - lots of documentation and examples are available there.
- [cmakefied](https://github.com/tamaskenez/cmakefied) - a complimentary repo to add CMake support to `imgui` (originally used by this repo but now replaced with a simpler repo called [imgui.cmake](https://github.com/pr0g/imgui.cmake), similar in design to [bgfx.cmake](https://github.com/bkaradzic/bgfx.cmake) mentioned above).

# bgfx-imgui
This code is a port of a [Gist](https://gist.github.com/RichardGale/6e2b74bc42b3005e08397236e4be0fd0) by Richard Gale.
It remains mostly intact other than a few fixes to build with the latest release of `bgfx` and all input handling has been removed so that `imgui_impl_sdl.h/cpp` implementations may be used instead.
`vs_ocornut_imgui.bin.h` and `fs_ocornut_imgui.bin.h` are copied from the [examples/common/imgui](https://github.com/bkaradzic/bgfx/tree/master/examples/common/imgui) of the [bgfx](https://github.com/bkaradzic/bgfx) repo (to make the use of `bgfx::EmbeddedShader` easier).

// ImGui BFFX binding
// In this binding, ImTextureID is used to store an OpenGL 'GLuint' texture
// identifier. Read the FAQ about ImTextureID in imgui.cpp.
// You can copy and use unmodified imgui_impl_* files in your project. See
// main.cpp for an example of using this. If you use this binding you'll need to
// call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(),
// ImGui::Render() and ImGui_ImplXXXX_Shutdown(). If you are new to ImGui, see
// examples/README.txt and documentation at the top of imgui.cpp.

// dear imgui: Platform Backend for SDL2
// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
// (Info: SDL2 is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc.)
// (Prefer SDL 2.0.5+ for full feature support.)
// Implemented features:
// [X] Platform: Clipboard support.
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen.
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy SDL_SCANCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
// [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
// [X] Platform: Basic IME support. App needs to call 'SDL_SetHint(SDL_HINT_IME_SHOW_UI, "1");' before SDL_CreateWindow()!.
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
// Read online: https://github.com/ocornut/imgui/tree/master/docs
// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen. (#2702)
// 2023-02-23: Accept SDL_GetPerformanceCounter() not returning a monotonically increasing value. (#6189, #6114, #3644)
// 2023-02-07: Implement IME handler (io.SetPlatformImeDataFn will call SDL_SetTextInputRect()/SDL_StartTextInput()).
// 2023-02-07: *BREAKING CHANGE* Renamed this backend file from imgui_impl_sdl.cpp/.h to imgui_impl_sdl2.cpp/.h in prevision for the future release of SDL3.
// 2023-02-02: Avoid calling SDL_SetCursor() when cursor has not changed, as the function is surprisingly costly on Mac with latest SDL (may be fixed in next SDL version).
// 2023-02-02: Added support for SDL 2.0.18+ preciseX/preciseY mouse wheel data for smooth scrolling + Scaling X value on Emscripten (bug?). (#4019, #6096)
// 2023-02-02: Removed SDL_MOUSEWHEEL value clamping, as values seem correct in latest Emscripten. (#4019)
// 2023-02-01: Flipping SDL_MOUSEWHEEL 'wheel.x' value to match other backends and offer consistent horizontal scrolling direction. (#4019, #6096, #1463)
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
// 2022-09-26: Inputs: Disable SDL 2.0.22 new "auto capture" (SDL_HINT_MOUSE_AUTO_CAPTURE) which prevents drag and drop across windows for multi-viewport support + don't capture when drag and dropping. (#5710)
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
// 2022-03-22: Inputs: Fix mouse position issues when dragging outside of boundaries. SDL_CaptureMouse() erroneously still gives out LEAVE events when hovering OS decorations.
// 2022-03-22: Inputs: Added support for extra mouse buttons (SDL_BUTTON_X1/SDL_BUTTON_X2).
// 2022-02-04: Added SDL_Renderer* parameter to ImGui_ImplSDL2_InitForSDLRenderer(), so we can use SDL_GetRendererOutputSize() instead of SDL_GL_GetDrawableSize() when bound to a SDL_Renderer.
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
// 2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
// 2022-01-12: Update mouse inputs using SDL_MOUSEMOTION/SDL_WINDOWEVENT_LEAVE + fallback to provide it when focused but not hovered/captured. More standard and will allow us to pass it to future input queue API.
// 2022-01-12: Maintain our own copy of MouseButtonsDown mask instead of using ImGui::IsAnyMouseDown() which will be obsoleted.
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
// 2021-08-17: Calling io.AddFocusEvent() on SDL_WINDOWEVENT_FOCUS_GAINED/SDL_WINDOWEVENT_FOCUS_LOST.
// 2021-07-29: Inputs: MousePos is correctly reported when the host platform window is hovered but not focused (using SDL_GetMouseFocus() + SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH, requires SDL 2.0.5+)
// 2021-06-29: *BREAKING CHANGE* Removed 'SDL_Window* window' parameter to ImGui_ImplSDL2_NewFrame() which was unnecessary.
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
// 2021-03-22: Rework global mouse pos availability check listing supported platforms explicitly, effectively fixing mouse access on Raspberry Pi. (#2837, #3950)
// 2020-05-25: Misc: Report a zero display-size when window is minimized, to be consistent with other backends.
// 2020-02-20: Inputs: Fixed mapping for ImGuiKey_KeyPadEnter (using SDL_SCANCODE_KP_ENTER instead of SDL_SCANCODE_RETURN2).
// 2019-12-17: Inputs: On Wayland, use SDL_GetMouseState (because there is no global mouse state).
// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
// 2019-04-23: Inputs: Added support for SDL_GameController (if ImGuiConfigFlags_NavEnableGamepad is set by user application).
// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
// 2018-12-21: Inputs: Workaround for Android/iOS which don't seem to handle focus related calls.
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
// 2018-11-14: Changed the signature of ImGui_ImplSDL2_ProcessEvent() to take a 'const SDL_Event*'.
// 2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
// 2018-06-08: Misc: Extracted imgui_impl_sdl.cpp/.h away from the old combined SDL2+OpenGL/Vulkan examples.
// 2018-06-08: Misc: ImGui_ImplSDL2_InitForOpenGL() now takes a SDL_GLContext parameter.
// 2018-05-09: Misc: Fixed clipboard paste memory leak (we didn't call SDL_FreeMemory on the data returned by SDL_GetClipboardText).
// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
// 2018-02-16: Inputs: Added support for mouse cursors, honoring ImGui::GetMouseCursor() value.
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
// 2018-02-05: Misc: Using SDL_GetPerformanceCounter() instead of SDL_GetTicks() to be able to handle very high framerate (1000+ FPS).
// 2018-02-05: Inputs: Keyboard mapping is using scancodes everywhere instead of a confusing mixture of keycodes and scancodes.
// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
// 2018-01-19: Inputs: When available (SDL 2.0.4+) using SDL_CaptureMouse() to retrieve coordinates outside of client area when dragging. Otherwise (SDL 2.0.3 and before) testing for SDL_WINDOW_INPUT_FOCUS instead of SDL_WINDOW_MOUSE_FOCUS.
// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

// dear imgui: Platform Backend for SDL2
// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
// (Info: SDL2 is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc.)
// Implemented features:
// [X] Platform: Clipboard support.
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen.
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy SDL_SCANCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
// [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
// [X] Platform: Basic IME support. App needs to call 'SDL_SetHint(SDL_HINT_IME_SHOW_UI, "1");' before SDL_CreateWindow()!.
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.

# Third Party Setup
> __Note__: _Nearly_ all steps listed here are now optional and are not required thanks to the new _superbuild_ CMake script and option (`-DSUPERBUILD=ON`) supported by the repository.
>
>All third party dependencies will be automatically downloaded and built as part of the normal configuration process (see instructions in the main [__README__](/README.md) and accompanying configure scripts for details).
## Setup
### Windows
- First run `VsDevCmd.bat` from a terminal of your choice.
- Most likely to be located here (year and version may differ).
- `"C:\Program Files\Microsoft Visual Studio\<year>\Community\Common7\Tools\VsDevCmd.bat" -arch=x64 -host_arch=x64`
- e.g. `"C:\Program Files\Microsoft Visual Studio\2022\Community\Common7\Tools\VsDevCmd.bat" -arch=x64 -host_arch=x64`
- _Note:_ `-arch=x64 -host_arch=x64` are required for `x86_64` otherwise `x86` (32bit) is used as the default.
- This is to ensure both the compiler (`cl.exe`) and Ninja are added to your path and can be found by CMake.
### macOS
- You may need to add `-DCMAKE_C_COMPILER=<path/to/c/compiler> -DCMAKE_CXX_COMPILER=<path/to/c++/compiler>` when running the CMake commands if a valid compiler cannot be found by CMake.
- Most likely locations include: `/usr/bin/clang`, `/usr/bin/clang++`, `/usr/local/bin/gcc`, `/usr/local/bin/g++` etc...
### Linux
- You may need to install a few libraries before the third party dependencies can be built (most notably OpenGL and X11 if they're not already on your system). You'll likely get CMake configure errors if you're missing them.
```bash
# suggested command
sudo apt-get install libx11-dev libglu1-mesa-dev libgl1-mesa-glx libxext-dev ninja-build
```
- ... to get X11, OpenGL, GLX and Ninja
## Install
On either Windows, macOS or Linux, `cd` to the `third-party` folder and run:
```cmake
cmake -B build
```
It's fine not to specify a generator, any should work (and the `CMakeLists.txt` file should handle either single or multi-config generators).
> Note: For single-config generators the above will configure the libraries to build in `Debug`. To build them in `Release` (after performing the step listed below to build the libraries in `Debug`), run `cmake -B build -DCMAKE_BUILD_TYPE=Release`, and then invoke `cmake --build build` again.
Then run:
```cmake
cmake --build build
```
> Note: For single-config generators (`Make`, `Ninja`) this will build the configuration provided by `-DCMAKE_BUILD_TYPE` (`Debug` by default if omitted). For multi-config generators (e.g. Visual Studio) `cmake --build build` will by default build the `Debug` configuration. To build `Release`, use `cmake --build build --config Release`.
It might take a little while but behind the scenes CMake will go away and download, configure, build and install `SDL`, `bgfx` and `Dear ImGui`.
Once everything is complete you should be able to continue with the instructions in the main [README](README.md).
## Emscripten
It's possible to build the third party dependencies for use with Emscripten. To do this run the same commands as before, only prefix the configure step with `emcmake`. It's recommended to use `embuild` as the build folder to stop Emscripten overwriting the native build that may already exist.
```bash
# install emsdk (instructions: https://emscripten.org/docs/getting_started/downloads.html)
# setup Emscripten environment variables
source <emsdk>/emsdk_env.sh # on macOS/Linux
# or
<emsdk>/emsdk_env.bat # on Windows
#
emcmake cmake -B embuild # configure for Emscripten
cmake --build embuild # build libraries for Emscripten
```
## Wrap-Up
If you plan to create several projects you could install these dependencies to a shared location and use `CMAKE_PREFIX_PATH` to point to that location when building.
All dependencies make use of `CMAKE_DEBUG_POSTFIX` which means all built debug libraries get a '`d`' suffix (the convention) appended, so both Debug and Release libraries are installed to the same location.
