Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Vehicle Pathfinding - Where To Start?

Hi there,

I would like to implement NavMesh pathfinding for vehicles in unreal engine as i need it for my game and I need some help with where to start. I am currently looking at the AIController, PathFollowingComponent and NavMovementComponent.

I would like to know which class i would need to override/inherit from and which functions are relevant for change the movement behaviour for nav agents.

Are there any unreal engine AI techies out there who could shed some light?

Okay, after roughly two days of scanning through the source code i have found the following:

UPathFollowingComponent::FollowPathSegment(float DeltaTime) - Is called from TickComponent (every frame) - Calculates target velocity - Calls UNavMovementComponent::RequestDirectMove

UNavMovementComponent::RequestDirectMove - Sets Super::Velocity, which is used to move the pawn

So can someone please confirm that overriding UNavMovementComponent::RequestDirectMove to steer towards the velocity vector passed by UPathFollowingComponent::FollowPathSegment is the correct way to implement basic vehicle pathfinding?
