Expert blueprint for hierarchical finite state machines (HSM) and pushdown automata for complex AI/character behaviors. Covers state stacks, sub-states, transition validation, and state context passing. Use when basic FSMs are insufficient OR implementing layered AI. Keywords state machine, HSM, hierarchical, pushdown automata, state stack, FSM, AI behavior.

Migration notes: godot-state-machine-advanced

Incremental upgrade for topics this skill covers. Apply one hop, stabilize/test, then next. Never skip hops.

If the project is < 4.0, follow godot-version-migration era bridges (legacy → 3→4) until 4.0, then these hops. Official 3→4: Upgrading from Godot 3 to Godot 4.

4.0 → 4.1

Official: Upgrading to Godot 4.1

  • AnimationNode._process requires new test_only parameter; blend_input/blend_node gain optional test_only.
  • AnimationNodeStateMachinePlayback.get_travel_path returns Array[StringName].

4.1 → 4.2

Official: Upgrading to Godot 4.2

  • Many AnimationPlayer/AnimationTree APIs moved to AnimationMixer base.
  • method_call_mode → callback_mode_method; playback_process_mode/process_callback → callback_mode_process.
  • playback_active → active on mixer; AnimationTree.tree_root typed as AnimationRootNode.
  • AnimationPlayer.seek gains optional update_only.

4.2 → 4.3

Official: Upgrading to Godot 4.3

  • Animation interpolate / track_find_key gain backward/limit options.
  • AnimationMixer._post_process_key_value object arg is uint64.
  • Skeleton3D.bone_pose_changed → skeleton_updated; BoneAttachment3D.on_bone_pose_update → on_skeleton_update.
  • Capture mode replaced; see Migrating Animations 4.0→4.3 article for blend/time semantics.

4.3 → 4.4

Official: Upgrading to Godot 4.4

  • @export_file Inspector assignments become uid:// — scripts expecting res:// strings must resolve UIDs or use @export_file_path (4.5+).

4.4 → 4.5

Official: Upgrading to Godot 4.5

  • Resource deep-duplicate and UID export-file changes affect inventory/quest/economy Resource graphs.

4.5 → 4.6

Official: Upgrading to Godot 4.6

  • AnimationPlayer assigned_animation / autoplay / current_animation are StringName (C# binary break).
  • get_queue returns StringName[].

4.6 → 4.7

Official: Upgrading to Godot 4.7

  • Re-validate Resource pipelines after packed-array setter and typed-return GDScript changes.
  • Animation.length uses double metadata (C# impact).
  • AnimationNodeBlendSpace1D/2D.add_blend_point optional name.
  • LookAtModifier3D.relative default is false (was true).
  • Packed array element assignment no longer triggers whole-property setter.
  • Typed-return overrides require an explicit return statement.
