FAQ

Is it possible to have a Flow Graph independent from the world?

Yes, it's a common use case, i.e. if you want to have a global "meta-quest" (controlling game's story) or graph tracking achievements. You can create a Flow Asset instance from anywhere in the game by calling UFlowSubsystem::StartRootFlow.

Are there plans to support variables similar to blueprints?

Personally, I have no plans to implement it. The community is free to tackle this challenge. You can check Discord channel where people are discussing their implementations.

It's not obvious which way to choose as a proper solution for all (at least most of) the projects. It could be

• blueprint-based variables
• blackboard-style
• blueprint-style, but using a method similar to @ryanjon2040 pull request: https://github.com/MothCocoon/FlowGraph/pull/86
• also might take inspiration from StateTree implementation in UE5

Flow Graph solution would need to include support for UObject references.
