Classes

  Type Name Description
Public class AAIController AIController is the base class of controllers for AI-controlled Pawns.  
Public class ADetourCrowdAIController    
Public class AGridPathAIController    
Public struct FAIBasicCounter    
Public struct FAIGenericID    
Public struct FAIMessage    
Public struct FAIMessageObserver    
Public class FAIMoveCompletedSignature    
Public struct FAIMoveRequest    
Public struct FAINamedID TCounter needs to supply following functions: default constructor typedef X Type; where X is an integer type to be used as ID's internal type TCounter::Type GetNextAvailableID() - returns next available ID and advances the internal counter uint32 GetSize() const - returns number of unique IDs created so far OnIndexForced(TCounter::Type Index) - called when given Index has been force-used.  
Public struct FAIRequestID    
Public struct FAIResCounter    
Public struct FAIResourceLock Structure used to define which subsystem requested locking of a specific AI resource (like movement, logic, etc.)  
Public struct FAIResourcesSet    
Public struct FBehaviorTreeDelegates    
Public struct FBehaviorTreeNodeInitializationData    
Public struct FCompactIndexedHandleBase Compact Index based handle that has a serial number to verify stale handles.  
Public struct FCompactIndexedHandleManager    
Public struct FFocusKnowledge    
Public struct FGenericTeamId    
Public struct FGraphAStar Generic graph A* implementation  
Public struct FGraphAStarDefaultNode Default A* node class.  
Public struct FGraphAStarDefaultPolicy    
Public struct FGridSize2D    
Public struct FIndexedHandleBase Index based handle that has a serial number to verify stale handles.  
Public struct FIndexedHandleManager    
Public struct FIndexedHandleManagerBase Handle Manager meant for FIndexedHandleBase and FCompactIndexedHandleBase derived classes, handles are given out from a freelist and are zero based and consecutive in nature, so ideal for being used as indices in to arrays.  
Public struct FIntervalCountdown    
Public class FRangeChecklessAllocator    
Public struct FSequentialIDBase    
Public struct FSimpleIndexedHandleBase Index based handle that doesn't use a serial number.  
Public class FVisualLoggerExtension    
Public class IAIModule The public interface to this module  
Public class IAIResourceInterface    
Public class IGenericTeamAgentInterface    
Public struct TBVTree BVTree - Bounding Volumes Tree  
Public struct TDefaultManagerInstanceTracker    
Public class THierarchicalHashGrid2D Hierarchical Hash Grid in 2D.  
Public struct TSimpleCellGrid No virtuals on purpose  
Public class UAIResource_Logic    
Public class UAIResource_Movement Copyright Epic Games, Inc. All Rights Reserved.  
Public class UAIResourceInterface    
Public class UAISubsystem A class representing a common interface and behavior for AI subsystems  
Public class UAISystem    
Public class UBrainComponent    
Public class UGenericTeamAgentInterface
