C++ (Cpp) UpdateMoveFocus Examples

Example #1

File: CrowdFollowingComponent.cpp Project: mysheng8/UnrealEngine

void UCrowdFollowingComponent::FollowPathSegment(float DeltaTime)
{
	if (!bEnableCrowdSimulation)
	{
		Super::FollowPathSegment(DeltaTime);
		return;
	}

	if (bUpdateDirectMoveVelocity)
	{
		const FVector CurrentTargetPt = DestinationActor.IsValid() ? DestinationActor->GetActorLocation() : GetCurrentTargetLocation();
		const FVector AgentLoc = GetCrowdAgentLocation();
		const FVector NewDirection = (CurrentTargetPt - AgentLoc).GetSafeNormal();

		const bool bDirectionChanged = !NewDirection.Equals(CrowdAgentMoveDirection);
		if (bDirectionChanged)
		{
			CurrentDestination.Set(Path->GetBaseActor(), CurrentTargetPt);
			CrowdAgentMoveDirection = NewDirection;
			MoveSegmentDirection = NewDirection;

			UCrowdManager* Manager = UCrowdManager::GetCurrent(GetWorld());
			Manager->SetAgentMoveDirection(this, NewDirection);

			UE_VLOG(GetOwner(), LogCrowdFollowing, Log, TEXT("Updated direct move direction for crowd agent."));
		}
	}

	UpdateMoveFocus();
}
