# engine-v5
This is another more radical fork of cocos2d-x game engine, use opanal for all platforms, single texture multi gpu texture handler, c++17...  
  
The readme of cocos2d-x v4: https://github.com/simdsoft/engine-v5/blob/master/README.ccv4.md  
  
  
### Goals summary:
1. C++17
2. forcus on native game dev only
3. Remove unnecessary sources
4. build engine as static or dynamic library support
5. If you have any other excellent goals, welcome
6. Excellent PRs from any guys are welcome, I will review & merge ASAP

  - [ ] XX3. Fully streaming play for all media file: .mp4, .mp3, .ogg, .wav
  - [ ] XX4. Streaming load for .ttf with freetype2
  - [x] XX5. Remove CCB(already removed in v4)
