The main features in detail of Cocos2d-x v3.13
Add VR plugin
TBD: add link of PG
Support ETC1 alpha channel
Thanks halx99's contribution, now cocos2d-x supports ETC1 alpha channel by default.
If want to use ETC1 alpha chaneel, you should put xxx.pkm and xxx.pkm@alpha in the same folder, and use it like this:
auto sprite = Sprite::create("xxx.pkm");
xxx.pkm@alpha is the resource for alpha channel. @alpha subfix is required by engine to load alpha texture automatically.
More detail usage can refer to the implementation of Sprite1ETC1Alpha in tests/cpp-tests/Classes/SpriteTest/SpriteTest.cpp.
AudioEngine performance for Android 4.2+
AudioEngine uses OpenSL ES on Android, and it supports decoding audio source file to PCM data in codes since Android 4.2. Now AudioEngine uses this feature to fix the performance issue. The performane is the same as before if running on Android 4.1 or lower version.
Android arm-64 support
Now we provide arm-64 bit 3rd party libraries, which means can build 64-bit apps on Android. You can use the command to build 64-bit apps:
cocos run -p android --app-abi arm64-v8a
Switch to use gcc 4.9 on Android
cocos2d-x switch to use clang in v3.12, but developers reported some crash issue that caused by using clang+gnustl_static, so we switch to use gcc 4.9. We will change to use clang+c++_static when c++_static is stable.
Upgrade CURL to 7.50.0
Because CURL has a bug about connect to IPV4 numerical IP address in NAT64 environment, and it is fixed in v7.50.0, so we upgrade to this version when v7.50.0 is released.
