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"

Change polygon cost (pathfinding)


Since there is check in de details of the recasted navmesh in the editor to show the default polygon cost I wonder if there is a way to change this cost. I know I can change area costs with SetFixedAreaEnteringCost & SetAreaCost functions, However, these functions work for areas (group of N-polygons). I want to change the cost of a concrete polygon. Does someone know if this is possible?

 for (const auto& Poly : AllPolys)
     const uint32 AreaId = this->GetPolyAreaID(Poly.Ref);
     // What I have now. It changes the cost of all polygons with just one iteration since all polys belong to the only area I have
     DefaultQueryFilter->SetFixedAreaEnteringCost(AreaId, 4);
     DefaultQueryFilter->SetAreaCost(AreaId, 2);
     // What I want. Change the cost of each polygon according to an external custom function
     const float MyPolyCost = AuxClass::getCost(Poly.Center)

Although I don't know if this is possible or not, another option would be to override the custom costs of the pathfinding algorithm. See the answer.
