I've spent the last few days writing simple examples for every single command in Leadwerks 3. Not only does this make the documentation more friendly, it also acts as a final test to make sure all the commands work the way they say they should. I make the C++ example and then Chris converts it to Lua (and tells me what I did wrong!).

I didn't realize it at first, but this really showcases the strength of API design of Leadwerks. Since you get full control over the execution and flow of a Leadwerks program, it's easy to learn from simple examples that demonstrate one idea. Below are a few examples for different commands in the API.
