Hello, I’m trying to write BehaviourTree task node in C++ and I have 2 questions:
How do I get Owner Actor - the AI controller (in blueprints it’s avilable as a connector from Event Receive Execute)?
Should I return Super::ExecuteTask(OwnerComp, NodeMemory) at the end of function?
OwnerComp.GetAIOwner(); // to get the controller
AIOwner->GetPawn(); // to get the actor
You should return the result your node decides and do not need to call Super.
Is the return value stored in some variable?
Yes, to add to luthage’s answer:
AAIController* AIOwner = OwnerComp.GetAIOwner(); // to get the controller
APawn* Pawn = AIOwner->GetPawn(); // to get the actor
You’ll need to add this include:
#include "AIController.h"What do you mean is it stored is some variable? You execute your task and then return whether the task succeeded or not.
Perhaps you should look at the code of the tasks that Epic provided. Shooter game is another good example.
