Purpose Summary

• C++ 17
• Focuses on native game dev (easy to use, fast deployment, intuitive)
• Bugfixes ASAP

Thirdparty

• All thirdparty prebuilt libs are built from https://github.com/axys1/buildware via github actions automatically.

Highlighted Features

• Add apple M1, android x64 support, contributed by @pietpukkel
• Improve windows workflow, support linking with engine prebuilt libs, read windows workflow guide
• Windows video player support (based on microsoft media foundation)
• Windows x64 build support
• Reimplement HttpClient based on yasio for concorrent http requests processing.
• 'Upstream-Version-License'
  • Third-party license overview for easier publishing of your commercial apps based on axys framework.
  • Some links to third party libs which support axys too.
  • Extensions having own license as part of there package.
• Refactor AudioEngine, OpenAL for all platforms
  • OpenAL Soft, pass -DAX_USE_ALSOFT=ON to cmake to force enabling it
  • OpenAL.framework, if no AX_USE_ALSOFT option specified, cmake script will choose it on osx/ios/tvos, even though it was marked as deprecated, but still available.
• Refactor UserDefault with mio
• Modularize all optional extensions, move from engine core folder to an extensions folder
• Implement all .wav formats supported by OpenAL Soft, such as MS-ADPCM, ADPCM, ...
• Use a modern GL loader Glad
• Google angle renderer backend support
• C++ 17 standard
• IOS/TVOS SDK 9.0 as minimal deployment
• Use fast pugixml
• Use curl for transferring data with URL syntax
• Use SAX parser for all plist files
• Spine-3.8 support
• Extension FairyGUI support
• ASTC 4x4/6x6/8x8 support (if hardware decoding is not supported, then software decoding is used)
• ETC2 RGB/RGBA support (if hardware decoding is not supported, then software decoding is used)
• Supported 2D physics engines (see also APPENDIX.md):
  • Box2D
  • Box2D-optimized
  • Chipmunk2D
• Supported 3D physics engines:
  • Bullet Physics SDK
• ImGui 1.87 integrated, easy to write game embedded tools, very easy to use, read ImGui for more info

Quick Start

Common Requirement Python

• Python-2.7.17+, Python-3.7+

Prerequisites

1. Enter axys root directory
2. Run python setup.py, restart the console after it has finished for environment variables to take effect

Windows (64/32 bit Visual Studio 2019/2022)

1. Install CMake 3.14+

2. Install Visual Studio 2019/2022 (it's recommended that you only use these versions)

3. Execute the following commands in a command line (Console, Window Terminal or Powershell)

   cd axys

   • for 32 bit Visual Studio 2019: cmake -S . -B build -G "Visual Studio 16 2019" -A Win32
   • for 64 bit Visual Studio 2019: cmake -S . -B build -G "Visual Studio 16 2019" -A x64
   • for 32 bit Visual Studio 2022: cmake -S . -B build -G "Visual Studio 17 2022" -A Win32
   • for 64 bit Visual Studio 2022: cmake -S . -B build -G "Visual Studio 17 2022" -A x64

Build excecutable in a command line (e.g. cpp-tests): msbuild .\build\axys.sln -target:cpp_tests -maxCpuCount

Improve 'Visual Studio' workflow, support linking with engine prebuilt libs

See windows workflow guide

Android

With Android Studio

1. Install Android Studio 2021.1.1+
2. When starting Android Studio for the first time, It will guide you to install the SDK and other tools, just install them
3. Start Android and choose [Open an existing Android Studio Project] and select axys\tests\cpp-tests\proj.android
4. Start Android Studio and Open [Tools][SDKManager], then switch to SDK Tools, check the Show Package Details, choose the following tools and click the button Apply to install them:
   • Android SDK Platform 33
   • Android Gradle Plugin (AGP) 7.2.2
   • Android SDK Build-Tools 30.0.3 match with AGP
   • Gradle 7.4.2
   • NDK r23c+
   • CMake 3.22.1+
5. Wait for Gradle sync finish.
6. Note: If you use non-sdk provided CMake edition, you will need to download ninja from https://github.com/ninja-build/ninja/releases, and copy ninja.exe to cmake's bin directory

Without Android Studio

1. Download command-tools from https://developer.android.com/studio#command-tools
2. Install Android devtools (for example in windows)

# unzip command-tools at D:\dev\adt\
# Install android devtools
cd D:\dev\adt\
mkdir sdk
.\cmdline-tools\bin\sdkmanager.bat --verbose --sdk_root=D:\dev\adt\sdk "platform-tools" "cmdline-tools;latest" "platforms;android-33" "build-tools;30.0.3" "cmake;3.22.1" "ndk;23.2.8568313"
set ANDROID_HOME=D:\dev\adt\sdk

# Goto xxx\proj.android
.\gradlew.bat assembleRelease -PPROP_BUILD_TYPE=cmake -PPROP_APP_ABI=arm64-v8a --parallel --info

iOS, tvOS and macOS

1. Ensure xcode12+ & cmake3.21+ are installed, install cmake command line support: sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install

2. Execute the following command
   sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

3. Generate xcode project

   • for ios arm64:
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=OS64
   • for ios armv7,arm64 combined:
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=OS
   • for ios simulator x86_64:
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=SIMULATOR64
   • for tvos arm64:
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=TVOS
   • for tvos simulator x86_64:
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=SIMULATOR_TVOS
   • for macos x86_64(Intel) cmake -S . -B build -GXcode -DCMAKE_OSX_ARCHITECTURES=x86_64
   • for macos arm64(M1) cmake -S . -B build -GXcode -DCMAKE_OSX_ARCHITECTURES=arm64

4. After cmake finishes generating, you can open the xcode project at build folder and run cpp-tests or other test targets.

5. Notes

   • The code signing is required to run the ios/tvos app on your device, just change the bundle identifier until the auto manage signing is solved
   • axys only provides armv7, arm64, x86_64 prebuilt libraries for ios/tvos

New Project

• Cpp: axys new -p org.axys1.hellocpp -d D:\dev\projects\ -l cpp --portrait HelloCpp
• Lua: axys new -p org.axys1.hellolua -d D:\dev\projects\ -l lua --portrait HelloLua

Notes

• ThreadLocalStorage (TLS)
  • ios x86 simulator ios>=10 and axys no longer provide x86 libraries
  • ios x64 or devices (armv7, arm64) ios sdk>=9.0
  • the 'OpenAL Soft' maintained by kcat uses TLS
