Migration notes: godot-animation-tree-mastery

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.

3.x → 4.0

Official: Upgrading from Godot 3 to Godot 4

  • AnimationTreePlayer removed → AnimationTree.
  • AnimationPlayer.add_animation() → add_animation_library() + AnimationLibrary.
  • AnimationTree set_process_mode() → set_process_callback().
  • Tween node removed — use Tweeners (create_tween()); available on 3.5+ for prep.

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

No skill-relevant breaking changes for this hop.

4.4 → 4.5

Official: Upgrading to Godot 4.5

No skill-relevant breaking changes for this hop.

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

  • Animation.length uses double metadata (C# impact).
  • AnimationNodeBlendSpace1D/2D.add_blend_point optional name for labeled blend positions.
  • LookAtModifier3D.relative default is false (was true) — re-check aim/IK setups beside the tree (skeleton_ik_lookat.gd).
