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 and some more (see 'Highlight Features' for more info).

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

• More clearly third-party libs 'Upstream-Version-License' for easy to publish your commercial apps based on engine-x
• 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
• Google angle renderer backend support
• C++ 14 standard
• IOS SDK 9.0 as minimal deployment
• Use fast pugixml
• Use curl for transferring data with URL syntax
• Use SAX parser for all plist file
• Spine-3.8 support
• Extension FairyGUI support
• ASTC 4x4/6x6/8x8 support (if hardware decoder not present, use software decoder)
• 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

Open Wiki for additional information too.

Common Requirement Python

• Python-2.7.17+, Python-3.7+

Prerequisites

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

Windows

1. Install CMake 3.14+
2. Install Visual Studio 2019 build (it's 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 any device
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=cmake/ios.mini.cmake
   • for arm64:
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=cmake/ios.mini.cmake -DCMAKE_OSX_ARCHITECTURES=arm64
   • for simulator x86_64:
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=cmake/ios.mini.cmake -DCMAKE_OSX_SYSROOT=iphonesimulator -DCMAKE_OSX_ARCHITECTURES=x86_64

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

5. Notes

   • The code sign required to run ios app on device, just change bundle identifier until the auto manage signing solved
   • engine-x only provide armv7, arm64, x86_64 prebuilt libraries for ios

Notes

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