No scene match the given

Error message

No scene match the given {sceneId}

What it means

SceneEditorGame.GetScene looks up the game-side Scene instance for a sceneId in its internal scenes dictionary and throws InvalidOperationException when no scene with that id is registered. It is the central resolution point for child scenes loaded into the editor's game session.

Solutions

  1. Ensure the child scene is loaded (EnsureContentScene / the scene-loading path) before performing entity operations against its id.
  2. Refresh stale scene ids after asset reload by re-resolving them from the current asset collection.
  3. Check SceneEditorGame.IsSceneLoaded (or equivalent tracking) before calling, or wrap calls in try/catch on InvalidOperationException.

Example fix

// before
var scene = game.GetScene(asset.Id); // asset may not be loaded game-side
// after
if (!game.IsSceneLoaded(asset.Id))
    await game.LoadSceneAndWait(asset);
var scene = game.GetScene(asset.Id);
Defensive patterns

Strategy: try-catch

Validate before calling

// track loaded scenes yourself before calling APIs that resolve by id
if (!loadedSceneIds.Contains(sceneId))
    await LoadSceneAsync(sceneAsset);

Type guard

bool SceneIsLoaded(SceneEditorGame game, Guid sceneId) => game.IsSceneLoaded(sceneId); // or maintain your own set of loaded ids

Try / catch

try { var scene = editorGame.GetScene(sceneId); /* use scene */ }
catch (InvalidOperationException ex) when (ex.Message.StartsWith("No scene match")) { await ReloadSceneAsync(sceneId); }

Prevention

When it happens

Trigger: Calling LoadEntity/UnloadEntity/UnloadEntities (or scene offset sync paths via parent/scene/newParent/anchor) with a sceneId that was never passed to the scene-loading API, or that was loaded then unloaded.

Common situations: Operating on a child scene whose load operation has not completed yet; referencing a scene asset that was reloaded/re-imported and received a new id; stale references after a scene was removed from the hierarchy.
