Roadmap

[halx99]

Notes

• Other performance topic: https://forum.cocos.org/t/topic/90248, showcase: http://www.icarus-li.com/video/d1.mp4
• ProgramState not cache, v3 cached, my cause some compatible issue
• At cocos2d-x-v4, the ProgramState could shared only object have same texture, such as

ProgramState* ProgramStateRegistry::getProgramState(ProgramType programType, Texture2D* texture)
{
 auto textureFormatEXT = texture ? texture->getTextureFormatEXT() : 0;
 
 char hashMe[sizeof(programType) + sizeof(texture)];
 memcpy(hashMe, &programType, sizeof(programType));
 memcpy(hashMe + sizeof(programType), &texture, sizeof(texture));
 auto key = XXH32((const void*)&hashMe, sizeof(hashMe), 0);

 auto iter = _programStateCache.find(key);
 if (iter != _programStateCache.end())
     return iter->second;

 auto programState = newProgramState(programType, textureFormatEXT);
 if (programState) {
     _programStateCache.emplace(key, programState);
 }
 return programState;
}

Engine core

• RenderTarget abstract
• Refactor enums map method, use table instead many much switch case
• Cache depthstencil state, tsl::robin_map
• Remove FileUtils::getFileDataFromZip, recommend use ZipFile instead
• ASTC 4x4/8x8 support
• ETC2 RGB/RGBA support
• Improve Image, fast forward compression texels data to GPU
• Refactor audio engine, OpenAL for all platforms
• Remove SimpleAudio
• Remove offthread file operation
• Explicit convert utf-8 file path to wide-string and call wide win32 file operation APIs
• Refactor Downloader, curl for all platforms, don't use scheduler to retrieve progress info, make it more reusable
• minizip-1.2.0
• ccMessageBox
• BMP support with stb_image
• Remove unused libuv
• Reorder child support
• Remove tinyxml2 dep, use pugixml instead
• Use xsxml for SAX parser only
• Multi meta textures v1.0
• ProgramStateRegistry
• ANGLE support.
• Use curl for HttpClient all platforms
• Remove xxtea
• Remove rapidxml dep
• Fix etc1 alpha test case, content size incorrect
• Remove fmod for linux
• Use stat to check regular file exist for android platform
• Use int64_t as return type for getFileSize
• ios .ogg support
• ZipUtils streaming API, support streaming play audio file in android obb
• Add & Improve play .wav audio at all platforms
• Remove unnecessary workaround to process audio tail frame at non-apple platforms.
• Cache ProgramState
• Remove socket.io websockets, use yasio for socket connection solution
• Fully streaming play for all media file: .mp4, .mp3, .ogg, .wav
• Streaming load for .ttf with freetype2
• Remove CCB(already removed in v4)
• Purely offthread load texture, use shared gl context
• Refactor UserDefault with file mapping io with encrypt support
• msaa
• Refactor VideoPlayer
• GPU texture array support
• OpenGL RenderBuffer for depth stencil buffer D24S8

Thirdparty

• Use git submodules to manage 3rd libs or marge 3rd repo to main repo
• Update zlib to 1.2.11

Extensions:

• move spine, ccs, dragonBones to extensions
• All extensions should be optional and can disable relax
• ImGuiEXT
• FairyGUI
• spine-3.8
• cocostudio
• dragonBones
• Also move lua binding to extension
• Also move spine-cpp to extension
• EncryptSystem
• particle system: https://github.com/effekseer

Toolsets And build env

• Use system env for cmake to avoid copy engine sources when create new project
• lua-template and lua-empty-test needs fix
• New command line tool
• GUI Peoject Creator
• Sence Editor with ImGui

Lua Binding

• Lua53 compat
• Use plainlua instead luajit
• make lua test works well
• Remvoe luasocket, use yasio for socket connection solution
• Use sol2 for binding framework instead tolua++

poors of LuaJIT

• Lack of maintain
• High crash from game developer
• Performance(jit==on) slow than planlua without restricts programing (luajit have to many programing restricts)

benefit of lua5.4

• compat bytecode 32,64bit app without any changes

[imtrobin]

Can you provide the dependencies source too, so we can also compile them.

[halx99]

I will provide later

[halx99]

@imtrobin ok done deps for win32, now you can do follow steps to run cpp-tests on win32

python download-deps.py
mkdir build
cd build
cmake -A Win32 ..

After vsproject generated, just open Cocos2d-x.sln to build cpp-tests and run it.

[weiwest]

Auto choice best renderer from multi backends.

[halx99]

android {
    aaptOptions {
       noCompress 'mp3','ogg','wav','mp4','ttf'
    }
}

Note: OpenAL is deprecated on macOS 10.15.6 and 11 (10.16).
"The OpenAL framework is deprecated and remains present for compatibility purposes. Transition to AVAudioEngine for spatial audio functionality."
