Create SubTreefeature to node context menu. - Added
TabViewto the main panel. Tree views now open in a new tab. - Close runtime tabs when exiting playmode.

- Added Expand Subtree context menu option to subtree nodes
- Removed breadcrumbs from main panel toolbar. Replaced with tabs
- Blackboard key value property label not appearing on some nodes
- Fixed node states in debugger when using subtrees
- Double clicking a subtree node when in playmode will open tree instance instead of asset
- Opening BehaviourTree Editor causes error #15
- Chance of failure comparison
- Blackboard keys can now be deleted using the delete key
- Runtime: Selector / Sequencer / Parallel nodes now actively tick all children rather than ticking from the previous child.
- Runtime: Added TickDelta to context object to support multiple tick modes
- Nodes: RandomPosition min/max values expanded to vector3
- Nodes: Parallel node now has a threshold property to determine how many children need to succeed before this node returns success.
- Editor: Behaviour Tree menu item is now accessed under
Window -> AI -> Behaviour Treeto conform with standard Unity tools - Editor: Grid snap size is now 225 by default.
- Editor: Populate GameObject behaviour tree instances to asset selector while in play mode
- Editor: Improved debugger performance when inspecting an active tree.
- Runtime: Conditional Nodes. Specialisation of an ActionNode which returns true/false. Has built in node option for negating the condition
- Runtime: BehaviourTreeInstance.ManualTick() function to control behaviour tree tick manually
- Runtime: BehaviourTreeInstance.StartBehaviour() function to manually start a behaviour
- Runtime: TickMode to control when the tree is ticked (update/fixedupdate/lateupdate/manual)
- Runtime: StartMode to control when the tree is started (awake/onenable/start/manual)
- Runtime: Unity profile markers for runtime and editor
- ProjectSettings: grid snap size to project settings
- ProjectSettings: autoSelectNodeHierarchy option to enable subtree selection by default
- Editor: Added icons to nodes on canvas
- Runtime: Removed Switch Node
- Runtime: Removed Interrupt Selector Node
- Runtime: Removed Random Selector Node
- Updated behaviour tree view classes to use [UXmlElement] attribute instead of deprecated uxml factory / traits
- N/A
- Improved Open Behaviour Tree dialog menu
- BlackboardKey 'Delete' context menu option now appears when clicking anywhere within the row
- Restructured repository to contain just the package rather than the project. Installation URL is now just https://github.com/thekiwicoder0/UnityBehaviourTreeEditor.git
- Increased node text size slightly and center aligned
- Increased node description size slightly
- Use GraphElement.Capabilities to disable node snapping rather than editor prefs
- Blackboard Keys can now be renamed by double clicking on the blackboard key label
- Nodes can be copy, pasted, and duplicated in the tree view
- Nodes snap to 15 pixels to align with the grid background. (Disabled adjacent node snapping)
The NodeProperty class replaces the BlackboardProperty class, allowing node variables to be specified on the node, or optionally bind them directly to a blackboard key value.
- Renamed BlackboardProperty to NodeProperty
- Added a default value to the NodeProperty class
- Exposing a NodeProperty variable on a node allows the value to be specified on the node instance or bind it to a blackboard key.
- Added blackboard key overrides to the BehaviourTreeInstance component allowing blackboard key values to be override at the game object level.
- Added a new Switch composite node which allows executing a specific child based on an index value.
Added runtime support for reading and writing blackboard values from components.
See BehaviourTreeInstance:
- SetBlackboardValue
- GetBlackboardValue
- FindBlackboardKey
- Renamed BehaviourTreeRunner to BehaviourTreeInstance
- Changed behaviour tree initialisation from Start to Awake
- Added missing string blackboard key type
- Added SetBlackboardValue method to BehaviourTreeInstance
- Added GetBlackboardValue method to BehaviourTreeInstance
- Added FindBlackboardKey method to BehaviourTreeInstance
- Added custom icon to BehaviourTreeInstance MonoBehaviour
The blackboard has been refactored significantly to support many more types, including any custom types defined in a project.
Note this will break any previously defined blackboard keys in your tree so you'll need to recreate them and assign them to a node.
Additionally, there are two new nodes:
- SetProperty
- CompareProperty
These nodes can be placed in a tree and used to set an arbitary blackboard key to a specific value, or compare a key to a specific value respectively.
- Added BlackboardProperty type for reading and writing blackboard keys from nodes.
- Added generic BlackboardKey type. Subclass this type to add support for custom types to the blackboard.
- Fixed editor assembly definition to only build for the editor.
None
- Added CHANGELOG.md
- Amended Samples folder name to adhere to unity package standards
- Added initial subtree implementation.
- Add a SubTreeNode to the graph and assign a behaviour tree to run it as a subtree in the graph.
- Auto Select nodes after they've been created so they appear in the inspector immediately
- New node scripts are automatically added to the tree on creation when dragging
- Block the UI while new node scripts are compiling
- Various other smaller changes and bug fixes
