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"

How do you get a Navigation path in UE4 4.20 in C++?

I'm currently trying to figure out how to get a Navigation path for my pawn in C++.The way I've seen people get the path is by using GetWorld()->GetNavigationSystem()->FindPathToLocationSynchronously(). But, in UE4 4.2, GetWorld()->GetNavigationSystem() returns a NavigationSystemBase which doesn't have the find path functionality. Does anyone know how I can find a path in 4.2 in c++?

Also the documentation online is out of date for the include for NavigationSystem.h, its now located in Runtime/NavigationSystem/Public/NavigationSystem.h

Any help would be appreciated!

I think I figured it out.

include "Runtime/NavigationSystem/Public/NavigationSystem.h"

then

UNavigationSystemV1* navSys = UNavigationSystemV1::GetCurrent(GetWorld()); UNavigationPath* path = navSys->FindPathToLocationSynchronously()

Just kidding, in 4.2 you have to add "NavigationSystem" to your projects Build.cs

and to get the path finding system and nav points

UNavigationSystemV1* navSys = FNavigationSystem::GetCurrent(GetWorld());

UNavigationPath* path = navSys->FindPathToLocationSynchronously(GetWorld(), GetPawn()->GetActorLocation(), position, NULL);

So my first answer worked on my work project and my second answer worked when I was in the UE4 Advanced Car template project. I'm pretty sure they are both engine version 4.20, so idk whats up with that.
