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?

Thanks

1 answer: sort voted first

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?
