"At work we are using behaviour tree's to run the ai for a game we are working on. We serialize tree's to json but hand editing those became a pain as tree structures become hard to follow in json. I couldn't find any suitable existing editors for data like that, so i decided to write a website to be able to edit those structures in a visual way. It is a website that takes a scheme file describing the types in the tree (hence the name TypedTree) and lets you create new tree's (or edit existing) in a visual (and type safe) way. Although the website itself is written in TypeScript (rendering through plain html and svg) you can generate the scheme's through a dotnet cli tool, a dotnet global tool or a Unity package. dotnet: https://github.com/bastianblokland/typedtree-generator-dotnet unity: https://github.com/bastianblokland/typedtree-generator-unity website: https://github.com/bastianblokland/typedtree-editor Because it uses json as the exchange type it should be trivial to add scheme generators for different languages. Also i think it would be awesome to have a vscode plugin to edit those tree's straight in the ide."
