A while ago I started developing a simple addon called ‘bge_shortcuts’ that helps to add shaders/scripts to a scene. These are intended to be used for quickly trying things out, or to give you a starting point for shaders and scripts.
Here is a quick video going over some of the features of it.
Thought I would tidy it up and get it out there today. If you think of any features that you think should be added, then open up a discussion about it in this thread. Over christmas I am going to be looking to add a night/day cycle (already quite far through with this) and various other character controllers. I am also looking into making it simple to add vehicle controllers with the addon.
Let me know what you think.
