DoN's 3D-Pathfinding / Flying-AI system (with full source!)

For a live example of how to use the plugin from C++ check out the “Fly To” node class (BTTask_FlyTo.h/.cpp) which includes the manager via DonNavigationHelper.h and uses the API directly. For your particular issue I suggest methodically comparing your setup with UBTTask_FlyTo. Make sure you’ve added the plugin’s module (“DonAINavigation”) as a dependency in own your project’s MyProject.build.cs file too. Finally, if you run into any common linkage errors try searching online as well.
