# findAction(forAnswers:) Searches the decision tree, following the branches corresponding to each of the specified answers, and returns the resulting action object. ``` func findAction(forAnswers answers: [AnyHashable : any NSObjectProtocol]) -> (any NSObjectProtocol)? ``` ## Parameters `answers` A dictionary mapping attributes (or questions) to values (or answers to those questions). ## Return Value The action object resulting from the decision-making process. ## Discussion Actions can be any type of object relevant to your game; you define action objects when creating the tree. Typically, an action object is a string or simple value type identifying the result of the decision-making process in the context of your game. In a manually created decision tree, an action is the “attribute” of a leaf node in the tree. That is, if you create a node using a method such as [`createBranch(value:attribute:)`](/documentation/GameplayKit/GKDecisionNode/createBranch(value:attribute:)), and create no further branches from that node, the `attribute` parameter of that node is treated as an action when evaluating the tree. In an automatically learned decision tree, you provide action values with the [`init(examples:actions:attributes:)`](/documentation/GameplayKit/GKDecisionTree/init(examples:actions:attributes:)) initializer. > Note: > If a tree contains random branches (defined with the ``doc://com.apple.gameplaykit/documentation/GameplayKit/GKDecisionNode/createBranch(weight:attribute:)`` method), you do not need to provide an answer for the corresponding attribute when finding an action. --- Copyright © 2026 Apple Inc.
