Behavior Trees (Bt*, animation-state-machine branch)
A data-oriented behavior tree framework for AI decision-making, built into the engine at Engine/H/Game/AI/BehaviorTree.h + Engine/Source/Game/AI/BehaviorTree.cpp. Designed for attachment to Game::Chr subclasses: build a tree of BtNode objects once in Chr::create(), call bt.tick(Time.d()) from Chr::update() each frame.




Animation Graph (Ag*) and IK (animation-state-machine branch)
A production-grade composable pose-graph animation system, built into the engine at Engine/H/Animation/AnimGraph.h + Engine/Source/Animation/AnimGraph.cpp. Sits on top of the existing AnimatedSkeleton::animate() primitives without modifying them, stylistically parallels the BehaviorTree framework on the same branch (Bt* prefix, namespace Game{}, non-virtual update() wrapper + protected doUpdate() dispatch, tree-walking virtuals for viz).
