Feature Suggestion – Find Task and Condition Usage

[patientzerogames]

Hi,

we heavily use NodeCanvas in our game (shameless plug: http://www.emerge-game.com) and it’s sometimes hard to find where a specific Task or Condition has been used in all the different FSMs.
It would be great if it was possible to search for a specific Task or Condition and see exactly where it is used.
I hacked togehter a search function to find Tasks and highlight the nodes which use it but it has several limitations (doesn’t work for Conditions, can’t easily open the FSM where the task was found if it isn’t open already etc.)
It would be great if you could properly integrate something similar (but hopefully far better :D) into nodecanvas directly.
Feel free to use my code as a starting point.

Hey!

I’m very glad to know that you use NodeCanvas in your game 🙂
I’ve just added your request to the roadmap, in which by the way there are some other search capabilities as well.
Thanks a lot for your suggestion as well as your initial code.
I will try to implement this as soon as possible.

Cheers!

Sorry if it was a duplicate request.
Where can I find the roadmap?

[Gavalakis]

I meant in the personal roadmap 🙂 It’s not public (at least right now).
Your request was not duplicate. Nothing to be sorry about!
