Custom render pipeline and custom update cycle

Is there a
custom render pipeline and custom update cycle available?

There’s not a custom render pipeline as such. For iOS, you can choose between OpenGL and Metal. There’s also a recent pull request about adding Vulkan (for Windows, at least initially).

Given that Solar2D is fully open source, if you know how to create custom render pinelines, then you can add such a thing for/by yourself.

For event updates, see https://docs.coronalabs.com/guide/events/detectEvents/index.html

goal is android,i have not the experience for it ^^
