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"

2D Navigation Grid for A* Pathfinding C++

I am pretty new to UE4 and C++ and i have to do my final Project with it. I am trying to make my own Navigation Grid for an A* Pathfinding alhorithm. My Problem right now is that i am not sure on how to detect if the Cell is Walkable or not. Right now i have a TArray NavGrid; that i fill with 0 for Walkable. For every Cell i create i also create a UBoxComponent and set its Position according to its position in the Grid.

UBoxComponent* CollisionComponent = NewObject(); CollisionComponent->OnComponentBeginOverlap.AddDynamic(this, &ANavGrid::Overlap); FVector ColisionPosition(X * GridPanelSize, Y * GridPanelSize, 0); CollisionComponent->AddRelativeLocation(ColisionPosition); NavGrid[Pos] = 0;

In the Overlap Function i want to get the Position of the CollisionComponent and Convert that to a Position in the Grid Array. How would i do this? Or is this even a good way to create the Grid for the Pathfinding?

Product Version: UE 4.15
