Last year I designed an asset using C# for sale on the Unity asset store. The asset creates branching dialogue in the game engine. It uses a custom visual interface to create many different nodes that control the game flow.
The challenge was not only creating a database of nodes that can be easily manipulated, but also to create an asset that is easily integratable with the customer’s existing code.
I wrote extensive documentation for the product, uploaded multiple tutorial videos on youtube, and continue to provide technical support for customers whenever needed.
The product makes multiple sales per month and has received favorable reviews.
Dialogue Chains can be found here.
