Syntax

UCLASS (Blueprintable, BlueprintType)  
class UNavWalkingMode : public UBaseMovementMode

Remarks

NavWalkingMode: a default movement mode for traversing surfaces and movement bases by using an active navmesh when moving the actor rather than collision checks. Note: This movement mode requires a NavMoverComponent be on the actor to function properly. This mode also contains some randomization to avoid navmesh look ups happening at the same time (which is fine for AI characters running on the server) but may cause issues if used on autonomous proxies.

 Project a location to navmesh to find adjusted height.
Protected function Const const INavigationDataInterface * Get Navigation data for the actor. Returns null if there is no associated nav data.
Public function UFunction BlueprintPure, Category UObject * Returns the active turn generator. Note: you will need to cast the return value to the generator you expect to get, it can also be none.
Protected function Virtual FVector

ProjectLocationFromNavMesh ( float DeltaSeconds,

 Switch collision settings for NavWalking mode (ignore world collisions)
Public function UFunction BlueprintCallable, Category void
