Hello and welcome to the Skyline Game Engine forum En929
We hope you enjoy the engine and learn all the skills needed to create a great 3D game.
It would be a good idea to watch TattieBoJangle's videos as they cover a vast area of the engine and some of the features you will discover and need to create your levels. The written documentation is currently being developed as skyline is in a BETA stage of development and a lot of the newer content being written is for the newer Gen2 although it is cross compatible to a point with Gen1.
http://www.forum.aurasoft-skyline.co.uk/viewtopic.php?f=46&t=1107We offer lua scripting as the main programming side to skyline and a visual module system to create all the mechanics you need.
3D can offer different challenges to 2D game programming but most of the setup and working with game content is the same apart from the extra dimension
We are here to help with any queries or bugs you find and are on the forums every day looking for new posts
On a sidenote, we are also developing Skyline Game Engine - Gen2 which offers faster performance and higher visual fidelity to create great looking 3D games with industry standard PBR and quick and easy workflows. Gen2 also offers more features while editing in the scene and has many more features being advanced. This is in private alpha at the moment and will be releasable in the next few coming months
p.s. check the forums out as it contains a lot of useful information and scripts already that will help you get going
