Visual Scripting for Finite State Machine and Behavior Tree

[hyperkvlt]

Coming from unity, I am so used using an asset called NodeCanvas. This asset allow user to use both FSM and BT (or even creating their custom graph) for their game. And you can run both type of graph by creating subgraph using scriptableobject, this allow user to create a very complex AI, character control, and easy to understand game workflow. This asset work by running nodes inside graph, these graph are created using scriptable objects and run on scene by using graph controller, the nodes inside the graph will be run in order and changed as the condition met, and they can also use variables they create and binded using blackboard and invoke events between different graph using signal.

It would be very useful for user if godot had a solution for visual scripting of both FSM and BT to create more complex AI and work flow.

There's a couple assets for this, e.g. https://github.com/imberny/VisualFSM or https://godotengine.org/asset-library/asset/817

Thanks! I'll check that later.

This is best handled by a plugin or extension, Godot doesn't provide any state machines or behaviour code, and the GraphEdit class is exactly designed for this kind of task, in the scope of a plugin

[hyperkvlt]

You're right. But it would be great if Godot provide an official AI behavior solution such as FSM or BT

We avoid adding too specific components, AI and behaviour code is very project specific, and there's no universal solutions

See #281 and https://github.com/bitbrain/beehave.

I see, so the developer need to either come with their own solution or third party plugin for AI system?
