Skylines Actions system and presets are the core to your projects dynamic objects. Many Actions can be used in interesting combinations for varying effects, but some times you need help to get the most out of them.
In Skyline most of the Actions can be made with script, so if you create a script based action, ie your script behaves as if there is an Action attached, Let us know and we will look at converting it to a C++ Action for Skyline.
The idea is to code re-usable sections of lua, say for example a door open script or a simple game controller then we could re-make the idea in c++ as an engine side action. It will be a while before we have a public c++ sdk, we do aim to have this in the not too distant future.
