AIGlobalPerceptionScale

Set/Unset a specific global scale for the AI perception.

ActionAbort

Use this node to define clean-up procedure executed when AI Action is aborted.

ActionEnd

Use this node to end the AI Action graph.

ActionStart

Represents the User and the used Object of an AI Action. Use this node to start the AI Action graph.

ActiveCount

Counts how many AIs are active.

ActiveCountInFaction

Counts the number of currently active AIs in a specific faction.

ActiveCountMonitor

Monitors active AI count against some limit, and outputs periodically the current state. When the condition is met, the monitor loop will stop automatically and it needs to be started manually again if desired.

AlertMe

Generic AI signal.

AttentionTarget

Outputs AI's attention target.

AutoDisable

Controls AutoDisable.

BehaviorTree

Reset the AI modular behavior tree.

Communication

The specified AI plays the given communication.

EventListener

The highest level of alertness of any agent in the level.

Execute

Executes an AI Action.

Faction

Simply passes the selected faction to the output port. This is more of a helper node to circumvent manual typing.

FactionReaction

Set/Get Faction reaction info.

GroupAlertness

The highest level of alertness of any agent in the group.

GroupCount

The highest level of alertness of any agent in the group.

GroupIDGet

Sets and outputs AI's group ID.

GroupIDSet

Merges AI group 'from' to group 'to'.

IgnoreState

Switching species hostility on/off (makes AI ignore enemies/be ignored).

IsAliveCheck

Check which actors of a group are alive.

LookAt

Sets AI to look at a point, entity or direction.

NavCostFactor

Set navigation cost factor for traveling through a region.

ObjectDrop

Drops grabbed object.

ObjectUse

Uses an object.

PerceptionScale

Scales the agent's sensitivity.

PerceptionState

Enabling/Disabling or Resetting AI actor's perception.

RegenerateMNM

Triggers recalculation of MNM data for a specified bounding box (leave blank for whole level).

RequestReinforcementReadability

When a reinforcement is spawned in the level, it could be helpful for the player to detect in the scene that one agent is performing some action to communicate the decision of calling backups.

This node has been introduced to allow level designers to request the AI to perform this readability action. An example of how to use the node can be found in the following picture:

The node is currently signaling AI that they are in a good moment to call reinforcement. The Done output is triggered when at least one AI in the specified group is alive and the signaling is performed.

Note that currently, the node doesn't guarantee that the readability action will be performed: this decision is in total control of the AI behavior and it could fail.

SetCommunicationVariable

While executing a behavior, AI agents will try to communicate their intentions triggering specific VO lines in the relation of the state they are in. Some states could have special variation, for example depending on the level the agent is.

Level designers need to give hints to the Communication Manager about which condition are fulfilled at each specific time. This node can be used to achieve this goal.

The variables are defined into the file: GameSDK\Scripts\AI\Communication\CommunicationVariable.xml

SetFaction

Set the faction an AI character belongs to.

SetState

Changes Smart Object State.

ShapeState

Enable or Disable AIShape.

ShootAt

Set AI to shoot at position or entity.
