GC allocs in FSM/Composite Graphs

[tedw4rd]

Hi Gavalakis,

I’ve been deciding if I want to use NodeCanvas in a very resource constrained project, and the fact that your behavior trees don’t create any GC allocations is really nice. However, I noticed that FSMs and composite graphs (i.e. FSMs with behavior tree nodes and behavior trees with FSM nodes) actually have a good bit of GC allocations associated with them. Do you have any future plans to get rid of those? Or is it possible I’m doing something incorrect when setting up those graphs?

Hello,

I took a look again and found the issue for the FSM, which in practice was a bad call, which you can fix easily as well 🙂
Please open ActionList.cs and replace line #86 (the bad call) with:

if (finishedIndex.Count == actions.Count)

Notice that this is a temporary fix for now, because it will not take into account the disabled actions (through the UI checkbox).
I will make sure it does for the next update along with some further improvements.

Let me know if this fixed the GC issue for you 🙂

Thanks,
Gavalakis Vaggelis

Yep! That knocked off a good chunk of the GC alloc I was seeing. Thanks for the suggestion!
