Download GameFlow 1.2.2 Free Unity
GameFlow is THE visual scripting tool for the rest of us. 100% free of graph nodes, completely integrated in the Inspector and designed not with the intention of replacing your C# scripting but mainly to give you a hand in adding logic and effects to your GameObjects. All quick and easy.
And versatile too, because GameFlow is like a swiss army knife with many uses: programming a whole game or only certain parts of it without writing code, controlling other scripts or components, adding localization, making your custom gizmos and macros (great for automation) and even creating your own utilities for the Editor. Yes, it can do that too.
