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);
|
|
||||||
|
|
||||||

# 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
