Member Data Documentation

◆ Filter

TSubclassOf<UNavigationQueryFilter> UBTT_GetRandomLocation::Filter = nullptr

Navigation Query filter used when picking the location, only picks locations reachable using this filter when assigned.

◆ MaxDistance

float UBTT_GetRandomLocation::MaxDistance = 1000.0f

Maximum distance the random location picked may be from pawn.

◆ MoveTargetLocation

FBlackboardKeySelector UBTT_GetRandomLocation::MoveTargetLocation
