# rlImGui
|

<img align="left" src="https://github.com/raysan5/raylib/raw/master/logo/raylib_logo_animation.gif" width="64">
|
||||
A Raylib integration with DearImGui
|
||||
|
||||
rlImgui provides a backend for [Dear ImGui](https://github.com/ocornut/imgui) using [Raylib](https://www.raylib.com/).
|
||||
|
||||
# Building
|
||||
rlImGui is setup to use premake to generate a static library and examples for Visual Studio 2019. Premake can also be used to generate makefiles for linux. rlImGui can be used as a static library, or by direclty including the files into your game project.
|
||||
|
||||
If you wish to use premake, you will need to download the Premake5 executable for your platform from. https://premake.github.io/download
|
||||
|
||||
# Setup
|
||||
|
||||
Using rlImGui in your code is very easy. Once you have included the library, or source files for rlImGui and ImGui in your project, simply do the following.
|
||||
```
|
||||
#include "rlImGui.h" // include the API header
|
||||
|
||||
// before your game loop
|
||||
rlImGuiSetup(true); // sets up ImGui with ether a dark or light default theme
|
||||
|
||||
// inside your game loop, between BeginDrawing() and EndDrawing()
|
||||
rlImGuiBegin(); // starts the ImGui content mode. Make all ImGui calls after this
|
||||
|
||||
rlImGuiEnd(); // ends the ImGui content mode. Make all ImGui calls before this
|
||||
|
||||
// after your game loop is over, before you close the window
|
||||
|
||||
rlImGuiShutdown(); // cleans up ImGui
|
||||
```
|
||||
|
||||
# Examples
|
||||
There are two example programs in the examples folder.
|
||||
|
||||
## Simple
|
||||
This is the most simple use of ImGui in raylib, it just shows the ImGui demo window.
|
||||
|
||||
|
||||
|
||||
## Editor
|
||||
This is a more complex example of ImGui, showing how to use raylib 2d and 3d cameras to draw into ImGui windows using render textures.
|
||||
|
||||
|
||||
# Extras
|
||||
|
||||
## rlImGuiColors.h
|
||||
This file has a converter to change Raylib colors into ImGui Colors
|
||||
|
||||
## Font Awesome Icons
|
||||
Support for Font Awesome 6 https://fontawesome.com/ is built into rlImGui and enabled by default. You can simply
|
||||
#include "extras/IconsFontAwesome6.h"
|
||||
To use the ICON_FA macros for any icon in the free set.
|
||||
|
||||
If you wish to disable font awesome support you can #define NO_FONT_AWESOME
|
||||
|
||||
|
||||
# Images
|
||||
Raylib textures can be drawn in ImGui using the following functions
|
||||
```
|
||||
void rlImGuiImage(const Texture *image);
|
||||
void rlImGuiImageSize(const Texture *image, int width, int height);
|
||||
void rlImGuiImageSizeV(const Texture* image, Vector2 size);
|
||||
void rlImGuiImageRect(const Texture* image, int destWidth, int destHeight, Rectangle sourceRect);
|
||||
void rlImGuiImageRenderTexture(const RenderTexture* image);
|
||||
void rlImGuiImageRenderTextureFit(const RenderTexture* image, bool center);
|
||||
|
||||
bool rlImGuiImageButton(const Texture *image);
|
||||
bool rlImGuiImageButtonSize(const char* name, const Texture* image, struct ImVec2 size);
|
||||
```
|
||||
|
||||
# C vs C++
|
||||
ImGui is a C++ library, so rlImGui uses C++ to create the backend and integration with Raylib.
|
||||
The rlImGui.h API only uses features that are common to C and C++, so rlImGui can be built as a static library and used by pure C code. Users of ImGui who wish to use pure C must use an ImGui wrapper, such as [https://github.com/cimgui/cimgui].
|
||||
|
||||
# Low level API
|
||||
If you would like more controll over the ImGui Backend, you can use the low level API that is found in imgui_impl_raylib.h. This is API follows the patterns of other ImGui backends and does not do automatic context management. An example of it's use can be found in imgui_style_example.cpp

// This is is the low level ImGui backend for raylib, a higher level API that matches the raylib API can be found in rlImGui.h
|

|

// 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.
