Engine-x

This is another more radical fork of Cocos2d-x-4.0, use OpenAL for all platforms, single texture multi GPU texture handler, C++14/17, etc.

简体中文

Purpose Summary:

• C++14/17
• Focus on native game dev (quick starting, easy to use, fast)
• Bugfixes ASAP
• Usefull PRs from you are welcome (review/merge ASAP)

Highlight Features:

• Refactor AudioEngine, OpenAL for all platforms
  • openal-soft, pass -DBUILD_EXT_ALSOFT=ON to cmake to force enable it
  • OpenAL.framework, if no BUILD_EXT_ALSOFT option specified, cmake script will choose it on osx/ios, even through it was mark as deprecated, but still available.
• Refactor UserDefault with mio
• Modularize all optional extension, move from engine core to folder extensions
• Implement all .wav formats supported by openal-soft, such as MS-ADPCM, ADPCM, ...
• Use modern gl loader glad (instead of glew)
• Add google angle renderer backend support
• C++14 standard
• IOS SDK 9.0 as minimal deployment
• Use fast pugixml
• Using curl for transferring data with URL syntax
• Use SAX parser for all plist file
• Spine-3.8 support
• Add engine extension FairyGUI support
• Add ASTC 4x4/6x6/8x8 support, if hardware decoder not present, use software decoder
• Add ETC2 RGB/RGBA support, if hardware decoder not present, use software decoder
• ImGui integrated, easy to write game embedded tools, very ease to use, please read ImGuiEXT

Roadmap

Quick Start

Common Requirement python

• python-2.7.17+, python-3.7+

Prerequisites

1. Enter engine-x root directory
2. Run python download-deps.py
3. Run python setup.py, restart console after finish

Windows

1. Install CMake 3.14+
2. Install Visual Studio 2019 build(we strong recommend you use this version)
3. Execute follow command at command line(Console, Window Terminal or Powershell)

cd engine-x\
cmake -S . -B build -G "Visual Studio 16 2019" -A Win32

Android

1. Install Android Studio 4.0+

2. When first start Android Studio, It will guide you to install sdk and other tools, just install them

3. Start Android and choose [Open an existing Android Studio Project] to open engine-x\tests\cpp-tests\proj.android

4. Start Android Studio and Open [Tools][SDKManager], then switch to SDK Tools, check the Show Package Details, choose follow tools and click the button Apply to install them:

   • Android SDK Platform 29 r5
   • Android SDK Build-Tools 29.0.2
   • NDK r16b+
   • CMake 3.10+

5. Waiting for Gradle sync finish.

6. Remark: If you use non-sdk provided CMake edition, you need download ninja from https://github.com/ninja-build/ninja/releases, and copy ninja.exe to cmake's bin directory

iOS

1. Ensure xcode11+ & cmake3.14+ installed, install cmake command line support: sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install
2. Execute follow command
   sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
3. Generate xcode project

  # for device arm64
  cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=cmake/ios.mini.cmake

  # for device combined armv7,arm64
  # cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=cmake/ios.mini.cmake "-DCMAKE_OSX_ARCHITECTURES=armv7;arm64"

  # for simulator x86_64
  # cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=cmake/ios.mini.cmake -DCMAKE_OSX_SYSROOT=iphonesimulator

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

5. Notes
   a. The code sign required to run ios app on device, just change bundle identifier until the auto manage siging solved
   b. engine-x only provide armv7,arm64,x86_64 prebuilt libraries for ios

Pitfalls

• ThreadLocalStorage(TLS)
  • ios x86 simulator ios>=10
  • ios x64 or devices(armv7,arm64) ios sdk>=9.0
  • the openal-soft maintained by kcat use TLS
