Cocos creator 2.3.+ bug on SkeletonJson parser. Please help!
0

Dear! After upgrade Cocos Creator to version 2.3.2, I can not play spine path constrain animation anymore (I have played success the same skeleton data in json format with Creator 2.2.2). After doing some investigations, seem the issue come from SkeletonJson.cpp:782

Json *paths = Json::getItem(root, “path”);

After updating code as below I got the path constrain play success on Creator 2.3.2.
Json *paths = Json::getItem(root, “paths”);

If the changes for new version is not a bug please give me some instructions for that case.
Thanks and regards!
