Hive development (for SamCameron’s comment) is in development, though on suspension.
Some of the advantages of HIVE are that an intermediary graph is produced, which can be used for sharing works with others without requiring the use of Blend Files, but also that other engines could (in theory) use the same graph. In addition, HIVE doesn’t write directly to a python script, instead it writes a configuration of “nodes” which can be accessed by other scripts, making the result modular.
In terms of your work, I would encourage you to consider how data gets from one “node” to another - rather than setting something every frame, it will be important to support events which “push” data along the node conections.
I do not think there is any relationship to HIVE. This is - as you explained very well - a complete different topic.
I think this thread is a good approach to design your own nodes editor for whatever you want. I personally do not think it is worth as a general programming tool. It can be really useful if a graph is much more descriptive than text (or logic bricks). For example I’m thinking of the state flow within a finite state machine.
Unfortunately just now I have the impression the node editor is not that sufficient for FSM graphs as its node graph mainly goes left to right (Just now I do not know if that is configurable) while FSM graphs have directed edges including loops. It might still be easier to read that than the logic bricks state view, but I’m still investigate into that.
I believe it does not matter if I want to generate Python code, Logic Bricks, objects in the scene or a mix of that. You can even have several different editors and each editor can have several data blocks with graphical configuration.
I for myself are trying to figure out what I can do with the node editor. If it turns out it is too limited for the purposes I want, I will not use it.
To alleviate the left-to-right limitations, use entry and exit nodes which are identified with unique names. This way, you can have multiple entry points to a state, and even keep it defined separately to places where it might be used.
