Neat video! I wish my eventing/whatevering would yield instant results :-P
But at least that's how music composition generally works for me.
That's interesting. It is exactly my experience too. Maybe because music composition already has that direct media connection? We instantly hear what we are playing, or how it affects the music if we change a note, a chord, an effect, etc.
Game design should feel the same.
I often read about complaints from non-programmers about the arrays in Construct. They said "I can't see them." And I didn't understand what they meant. Until I saw this video and its part about binary search. It's the same algoritm, that I use in "Verve!" for Construct's arrays. But all my comments in the events can't explain the functionality nearly as obvious than Bret's visual representation. This must have been what the people meant by "seeing the array".
But there's a downside. Making an editor with instant media connection would always be a solution to specific demands or else will be bloated with dozens of tools and functions you probably never need.
One side-note: I think, Bret's principle is exactly what people find so attractive about Spriter. It is following exactly this principle. You instantly see what you are doing and how changes affect it. I'm sure, there are other examples from fellow Scirrans out there.
