Variables

  Type Name Description
Public variable bool bSightQueriesOutOfRangeDirty  
Protected variable UProperty Category, EditDefaultsOnly Config bool bUseAsynchronousTraceForDefaultSightQueries Defines if we are allowed to use asynchronous trace queries when there is no IAISightTargetInterface for a Target
Protected variable ECollisionChannel DefaultSightCollisionChannel  
Public variable TMap< FPerceptionListenerID, FDigestedSightProperties > DigestedProperties  
Protected variable float HighImportanceDistanceSquare  
Protected variable UProperty Category, EditDefaultsOnly Config float HighImportanceQueryDistanceThreshold  
Protected variable UProperty Category, EditDefaultsOnly Config int32 MaxAsyncTracesPerTick Maximum number of asynchronous traces that can be requested in a single update call
Protected variable UProperty Category, EditDefaultsOnly Config float MaxQueryImportance  
Protected variable UProperty Category, EditDefaultsOnly Config double MaxTimeSlicePerTick  
Protected variable UProperty Category, EditDefaultsOnly Config int32 MaxTracesPerTick  
Protected variable UProperty Category, EditDefaultsOnly Config int32 MinQueriesPerTimeSliceCheck  
Public variable int32 NextOutOfRangeIndex The SightQueries are a n^2 problem and to reduce the sort time, they are now split between in range and out of range Since the out of range queries only age as the distance component of the score is always 0, there is few need to sort them In the majority of the cases most of the queries are out of range, so the sort time is greatly reduced as we only sort the in range queries
Public variable FTargetsContainer ObservedTargets  
Protected variable FOnPendingVisibilityQueryProcessedDelegate OnPendingCanBeSeenQueryProcessedDelegate  
Protected variable FTraceDelegate OnPendingTraceQueryProcessedDelegate  
Protected variable UProperty Category, EditDefaultsOnly Config float PendingQueriesBudgetReductionRatio Defines the amount of async trace queries to prevent based on the number of pending queries at the start of an update.
Protected variable UProperty Category, EditDefaultsOnly Config float SightLimitQueryImportance  
Public variable TArray< FAISightQuery > SightQueriesInRange  
Public variable TArray< FAISightQuery > SightQueriesOutOfRange  
Public variable TArray< FAISightQuery > SightQueriesPending
