Currently, rotating selected cells in a GridMap doesn't create an action, and therefore can't be undone. This PR modifies that.

react-konvaを利用して、以下機能を持ったお絵かきアプリを作っていく。 ペンツール（色の選択が可能）で線が描ける 進む戻る（UndoRedo）機能が使える 円ツールで円が描ける 背景画像付き gitにソースコード全量あげたのでこちらも参考に。react-konvaデモ（GitHub） 今回はReact19・TypeScriptを利用している "react": "19.1.0", "typescript": "^4.9.5", "konva": "9.3.20", "react-konva": "^19.0.4", Konva・react-konvaのインストール npm install react-konva konva --save ■ react-konvaとは KonvaをReactで使いやすくしたKonva公式のライブラリ。HTML5canvasをReactコンポーネントとして扱えるツールで、図形を操作したり、アニメーションをつけたりできる ■ 基本構造（Stage、Layer、Line） simple.tsx Stage // 大きさ定義ないと動かない width={300} height={300} > Layer> Line points={} stroke="red" /> Layer> Stage> Stage キャンバスの土台みたいなもの。このStage上でないとkonvaは動かない Layer レイヤー層。レイヤーを分けると不要なレンダリングを防げたりする（背景画像とペンツール描画部分を分けたり）ただやみくもに増やせばいいものではなく、最大3－5個程度らしい参考 Line といった１つの配列の値を繋いで線を描いている。x,yのセットで1つの配列の中に順に詰めていくようになっており、実際は大量の値を繋いで滑らかにみえるようになる ■ 基本イベント（Mouse系） onMouseMove （onTouchMove） マウスの移動をキャッチするイベント。これでマウスに沿って線を書ける。ipad対応する場合はonTouchMoveを利用することで対応できる。 onMouseMove.tsx // 例えば左上（1,1）からスタート const = useStatenumber[]>(); // マウスを動きに沿って現在地をセット const handleMouseMove = (e) => { const point = e.target.getStage().getPointerPosition(); setLine([...line, point.x, point.y]); }; return ( Stage width={500} height={500} onMouseMove={handleMouseMove} onTouchMove={handleMouseMove}> Layer> Line points={line} stroke="black" /> Layer> Stage> ); …

renevanderark: > will the reference to this orphaned node then be cleaned up by the undo_redo_manager later? That’s what the `add_do_reference()` does when erasing the history as far as I can tell from the code. This add it to a list of references to delete: github.com/godotengine/godot #### core/object/undo_redo.cpp `be3ecaeb3` 241. void UndoRedo::add_do_reference(Object *p_object) { 242. ERR_FAIL_NULL(p_object); 243. ERR_FAIL_COND(action_level <= 0); 244. ERR_FAIL_COND((current_action + 1) >= actions.size()); 245. Operation do_op; 246. do_op.object = p_object->get_instance_id(); 247. if (Object::cast_to<RefCounted>(p_object)) { 248. do_op.ref = Ref<RefCounted>(Object::cast_to<RefCounted>(p_object)); 249. } 250. 251. do_op.type = Operation::TYPE_REFERENCE; 252. actions.write[current_action + 1].do_ops.push_back(do_op); 253. } And here deletes them when the action can be re-done: github.com/godotengine/godot #### core/object/undo_redo.cpp `be3ecaeb3` 51. void UndoRedo::discard_redo() { 52. if (current_action == actions.size() - 1) { 53. return; 54. } 55. 56. for (int i = current_action + 1; i < actions.size(); i++) { 57. for (Operation &E : actions.write[i].do_ops) { 58. E.delete_reference(); 59. } 60. //ERASE do data 61. } 62. 63. actions.resize(current_action + 1); 64. }

I had a sleep and got an idea how to solve this problem. And it kinda worked. I noticed that there is no problem with removing nodes from grid when they were created. As I use same function in loading and creating nodes anew, there is some differences. How I see this situation: 1. I am creating my node from template and initializing it with data 2. If this node is new, I am using UndoRedo and action `do_method` not called. But node is adding to canvas when `node.tree_entered` invoked and all is going good. 3. If this is loading case, I just called `add_child(node)` and something gone wrong when I tried to delete it. Problem was resolved when I changed immediate `add_child` call with `call_deferred` func create_node(node_data: GraphNodeData, first_load: bool = false) -> GraphDataNode: var node: GraphDataNode = node_template.instantiate() var node_name = str(node_data.node_id) node.initialize(node_name, node_data, undo_redo) if not first_load: undo_redo.create_action("Create Node") undo_redo.add_do_method(add_child.bind(node)) undo_redo.add_undo_method(remove_child.bind(node)) undo_redo.commit_action() node.selected = true else: call_deferred("add_child", node) node.tree_entered.connect(_on_node_entered_tree.bind(node)) return node I am still curious about how this works and why after 1-frame-delay I don’t have any problems with signals disconnection. But my initial problem is solved
