A Qt-based Live2d widget

Introduction

QtLive2d is a Qt-based Live2d widget, it is modified from the official Live2d Sample. Unlike the official examples, QtLive2d uses QOpenGLWidget and QOpenGLFunctions provided by Qt instead of glfw and glew. This makes it easy to combine with any Qt Gui software.

Thanks @6ziv for your blogs and projects. They have helped me a lot on this project

Feature

• Easy to use
• Using OpenGL instead of WebGL
• Less resource consumption
• Support Live2d mouse events
• Support transparent background
• CrossPlatform (Qt is CrossPlatform, haven't test on other platform yet)

Sample

We provide a sample application called Sample to show you how to use it.

Build

Dependency

• Live2DCubismCore.lib
• Framework.lib
• OpenGL32
• User32
• Glu32

Usage

1. Please use MSVC 2017 or 2019! and std C++ 17
2. To use QtLive2d in your program, you need to add Floder QtLive2d, Framework, thirdParty and Core into you project.
3. Add includepath and dependpath in pro file

   INCLUDEPATH += $$PWD/Core/include
   INCLUDEPATH += $$PWD/Framework/src
   INCLUDEPATH += $$PWD/thirdParty/stb
   DEPENDPATH += $$PWD/../dll

4. Define flags in pro file

   DEFINES += WIN32
   DEFINES += _WINDOWS
   DEFINES += CSM_TARGET_WIN_GL

5. Compiling Framework and add Framework.lib into pro file.
6. Add other libs into pro file.

    CONFIG += debug_and_release
    CONFIG(debug, debug|release){
      message(Debug build)
      LIBS += -L$$PWD/lib/ -lLive2DCubismCore_MDd
      LIBS += -L$$PWD/lib/ -lFrameworkd
   
    }
   
    CONFIG(release, debug|release){
      message(Release build)
      LIBS += -L$$PWD/lib/ -lLive2DCubismCore_MD
      LIBS += -L$$PWD/lib/ -lFramework
   
    }
    LIBS += -lOpenGL32
    LIBS += -lUser32
    LIBS += -lGlu32

7. QLive2dWidget is a subclass of QOpenGLWidget, which can be used directly or be promoted in the Qt Designer.
8. To use QOpenGLWidget in Qt, you need add extra moudules.

   QT       += core gui opengl openglwidgets
   greaterThan(QT_MAJOR_VERSION, 5): QT += widgets

9. Define you model path in LAppDefine.cpp.
10. Enjoy it!
