Changed

Arbor Editor

• Supports node name change for all node types.
• Changed to display the behavior title bar on the calculator node.

Behaviour Tree

• Changed to automatically display AbortFlags field and Boolean field even if Decorator’s custom editor is implemented.
• Changed the default behavior of ActionBehaviour.OnExecute from “return failure” to “do nothing”.

ObjectPool

• Changed to stop when the graph is pooled.
• Changed to start playback if playOnStart is true when the graph returns from the pool.
• Changed to sleep when Rigidbody is pooled.
• Changed to wake up when Rigidbody resumes from the pool.
• Changed to sleep when Rigidbody2D is pooled.
• Changed to wake up when Rigidbody2D resumes from the pool.

Built in Component

• Changed the Add Component menu of Agent Controller to “Arbor > Navigation > Agent Controller”.
• Changed Waypoint’s Add Component menu to “Arbor > Navigation > Waypoint”.
• Changed AgentController to derive from MovingEntity class.
• Renamed AgentController.Follow to MoveTo

Built in StateBehaviour

• Renamed AgentEscape to AgentEscapeFromTransform
• Renamed LoadLevel to LoadScene
• Renamed UnloadLevel to UnloadScene

Built in Decorator

• Changed so that it does not interrupt even if AbortFlags.LowerPriority is set in TimeLimit.

Parameter Container

• Changed the parameter addition menu to the Add Component menu format.

Unity support

• Raised Unity’s minimum action version to 2019.4.0f1.
• Support for Unity2022.2.0b2

Examples

• Unified namespace to “Arbor.Examples”.
• Unified the group of AddComponent menu to “Arbor > Examples”.
• Unify the group of behavior addition menu to “Examples”.

Improved

Data flow

• Improved enum type boxing
  (To minimize the boxing of enum types, register the target type with ValueMediator.RegisterEnum<T>())

Built in Component

• Adjusted the behavior so that it does not fit as much as possible when cornered by the wall with AgentController.Escape.

Built in scripts

• Improved boxing of SetParameter
• Added support to disable related scripts when the Unity UI package is removed.
• When Active Input Handling is set to “Input System Package (New)”, the related script is disabled.
