Kyatric has done a good job listing game mechanics in his FAQ.
Would it be a good idea to start an FAQ of common expressions?
EG. A capx could show how to use the Lerp, Clamp & Delta Time expressions to create a Smooth Slideshow Transition
I feel there's a jump from learning basic coding logic to advanced expressions.
Learning how expressions work by playing with a Capx could make it easier, especially if there's a categorised list of examples. Iv learnt the Definitions of Native Expressions but it's hard to visualise how they would work together in a game mechanic.
