我担心以前从未听说过Layaair。 通常，引擎从这里获取使用兼容编程语言（C＃，TypeScript / JavaScript，C，C ++等）的Spine Runtime的源代码：https：//github.com/EsotericSoftware/spine-runtimes

I'm afraid we've never heard of Layaair before. Usually, engines take the source code of a Spine Runtime that uses a compatible programming language (C#, TypeScript/JavaScript, C, C++, etc.) from here: GitHub - EsotericSoftware/spine-runtimes: 2D skeletal animation runtimes for Spine.
