Namespace UE4.AIModule

Classes

AIController

AIController is the base class of controllers for AI-controlled Pawns.

AIDataProvider_QueryParams

AIDataProvider_QueryParams is used with environment queries It allows defining simple parameters for running query, which are not tied to any specific pawn, but defined for every query execution.

AIPerceptionComponent

AIPerceptionComponent is used to register as stimuli listener in AIPerceptionSystem and gathers registered stimuli.

AIPerceptionStimuliSourceComponent

Gives owning actor a way to auto-register as perception system's sense stimuli source

AIPerceptionSystem

By design checks perception between hostile teams

AITask_LockLogic

Locks AI logic until removed by external trigger

BlackboardKeyType_NativeEnum

DEPRECATED, please use UBlackboardKeyType_Enum instead

Auxiliary nodes are supporting nodes, that receive notification about execution flow and can be ticked Because some of them can be instanced for specific AI, following virtual functions are not marked as const:

OnBecomeRelevant
OnCeaseRelevant
TickNode If your node is not being instanced (default behavior), DO NOT change any properties of object within those functions! Template nodes are shared across all behavior tree components using the same tree asset and must store

BTComposite_Selector

Selector composite node.

BTComposite_Sequence

Sequence composite node.

BTComposite_SimpleParallel

Simple Parallel composite node.

BTCompositeNode

BTComposite Node

BTDecorator

Decorators are supporting nodes placed on parent-child connection, that receive notification about execution flow and can be ticked Because some of them can be instanced for specific AI, following virtual functions are not marked as const:

OnNodeActivation
OnNodeDeactivation
OnNodeProcessed
OnBecomeRelevant (from UBTAuxiliaryNode)
OnCeaseRelevant (from UBTAuxiliaryNode)
TickNode (from UBTAuxiliaryNode) If your node is not being instanced (default behavior), DO NOT change any properties of object within those functions! Template nodes are shared across all behavior tree components using the same tree asset and must store

BTDecorator_Blackboard

Blackboard decorator node.

BTDecorator_BlackboardBase

BTDecorator Blackboard Base

BTDecorator_BlueprintBase

Base class for blueprint based decorator nodes.

BTDecorator_CheckGameplayTagsOnActor

GameplayTag decorator node.

BTDecorator_CompareBBEntries

Blackboard comparison decorator node.

BTDecorator_ConditionalLoop

Conditional loop decorator node.

BTDecorator_ConeCheck

Cone check decorator node.

BTDecorator_Cooldown

Cooldown decorator node.

BTDecorator_DoesPathExist

Cooldown decorator node.

BTDecorator_ForceSuccess

Change node result to Success useful for creating optional branches in sequence Forcing failed result was not implemented, because it doesn't make sense in both basic composites:

sequence = child nodes behind it will be never run
selector = would allow executing multiple nodes, turning it into a sequence.

BTDecorator_IsAtLocation

Is At Location decorator node.

BTDecorator_IsBBEntryOfClass

BTDecorator Is BBEntry Of Class

BTDecorator_KeepInCone

Cooldown decorator node.

BTDecorator_Loop

Loop decorator node.

BTDecorator_ReachedMoveGoal

Reached Move Goal decorator node.

BTDecorator_SetTagCooldown

Set tag cooldown decorator node.

BTDecorator_TagCooldown

Cooldown decorator node.

BTDecorator_TimeLimit

Time Limit decorator node.

BTFunctionLibrary

BTFunction Library

BTNode

BTService

Behavior Tree service nodes is designed to perform "background" tasks that update AI's knowledge.

BTService_BlackboardBase

BTService Blackboard Base

BTService_BlueprintBase

Base class for blueprint based service nodes.

BTService_DefaultFocus

Default Focus service node.

BTService_RunEQS

BTService Run EQS

BTTask_BlackboardBase

BTTask Blackboard Base

BTTask_BlueprintBase

Base class for blueprint based task nodes.

BTTask_FinishWithResult

Instantly finishes with given result

BTTask_GameplayTaskBase

Base class for managing gameplay tasks Since AITask doesn't have any kind of success/failed results, default implemenation will only return EBTNode::Succeeded In your ExecuteTask:

use NewBTAITask() helper to create task
initialize task with values if needed

BTTask_MakeNoise

Make Noise task node.

BTTask_MoveDirectlyToward

Move Directly Toward task node.

BTTask_MoveTo

Move To task node.

BTTask_PawnActionBase

Base class for managing pawn actions Task will set itself as action observer before pushing it to AI Controller, override OnActionEvent if you need any special event handling.

BTTask_PlayAnimation

Play indicated AnimationAsset on Pawn controlled by BT Note that this node is generic and is handing multiple special cases,

BTTask_PlaySound

Play Sound task node.

BTTask_PushPawnAction

Action task node.

BTTask_RotateToFaceBBEntry

BTTask Rotate to Face BBEntry

BTTask_RunBehavior

RunBehavior task allows pushing subtrees on execution stack.

BTTask_RunBehaviorDynamic

RunBehaviorDynamic task allows pushing subtrees on execution stack.

BTTask_RunEQSQuery

Run Environment Query System Query task node.

BTTask_SetTagCooldown

Cooldown task node.

BTTask_Wait

Wait task node.

BTTask_WaitBlackboardTime

Wait task node.

BTTaskNode

Task are leaf nodes of behavior tree, which perform actual actions Because some of them can be instanced for specific AI, following virtual functions are not marked as const:

ExecuteTask
AbortTask
TickTask
OnMessage If your node is not being instanced (default behavior), DO NOT change any properties of object within those functions! Template nodes are shared across all behavior tree components using the same tree asset and must store
