Big spike when I enable behavior trees

[Sylmerria]

Hi !

I have big hit performances in my game when I enable behavior trees.
Like show the image below, 6 behavior trees take 13ms to initialize.



my code to start this behavior trees is :

Profiler.BeginSample("[AgentTracer][Activate] Init BT");
_behaviorTree.SetVariableValue("Speed", _agentTracer.Speed);
_behaviorTree.EnableBehavior();
Profiler.EndSample();

And the behavior tree model



How can I reduce this because I will have many more BT in the future

Thanks

There have been some optimizations for the next version but the best bet is to deserialize the tree first and pool that result. Take a look at this page for an example:
