Deleting an object in a container tab only cleared references inside
the template. Placements in scenes and other containers kept their
instance edit and showed "(missing)" in the inspector.
- shownObjectIds records which objects every holder shows before the
delete. dropReferencesToGone compares that with the state after it
and clears each reference that no longer resolves.
- A reference is resolved from its own place with referenceCandidates,
the same way the runtime does. One rule covers instance edits,
nested placements and full ids like p~crate.
- A cleared instance edit is dropped when it now says the same as the
template's own value. Without such a value a marked None stays, as
if picked by hand, and Reset hands the row back to the template.
- All cleared references come back with a single undo.
- References that were already dead in saved projects stay untouched.
Findings, not fixed here:
- A reference from container D into a nested placement q is stored as
q~<id>, but the copy is named r~q/<id> in every placement of D. The
runtime finds nothing, so that reference is dead from the start.
- Delete asset removes placed objects by cascade but does not clear
references to them.
Tests:
- Unit object-references: 17 passed (13 + 4)
- Gate: 198 files, 2873 tests, exit 0
- e2e 1-17,57: 564 checks passed, 57 has 13 (+1 for 57h)
- Five unit counter-probes and one browser counter-probe fail as
expected
- e2e total 1607 is computed, not measured in a full run

Choosing the target of an object variable meant finding its name in
a dropdown. With many objects, or several with the same sprite, the
name alone does not say which one it is. The eyedropper lets you
click the object where you see it instead.
- Every object dropdown gets an eyedropper button next to it. This
covers variables, struct fields and list entries, in the Inspector
and in the Variables tab.
- The button opens the Scene View or the container tab the object
lives in. A strip above the view names the field and the current
candidate and offers Take and Cancel. The cursor is a crosshair.
- A click picks a candidate and writes nothing yet. The candidate
gets its own cyan frame, the selection stays on the object with
the variable.
- Clicking follows the selection rule. `pickOn` in
`src/viewport/pick.ts` uses `pressOn` and only counts objects the
dropdown offers. A click on empty space keeps the candidate.
- Enter or Take writes through the same handlers as the dropdown.
That is one undo step, or none if nothing changes.
- Esc, Cancel, a right click in the view or a second click on the
button cancel without writing. So do a tab switch, another
selection, undo, redo, play and loading a project.
- After Take or Cancel the editor goes back to the tab the pick came
from.
- While the eyedropper runs, the view does not drag, marquee, paint,
show handles or open its context menu. Panning and zooming stay.
Found on the way:
- Started from the Variables tab, the click missed the object. The
Scene View is hidden while that tab is open, and the layout skips
hidden children. The strip appeared then, the view moved down by
32 px but kept its old height. `Editor.display()` now lays the row
out again after showing it.
Tests (on melektaus-atx):
- unit pick and object-pick: 27 passed, 13 new
- gate: 196 files, 2844 tests, CHECK EXIT 0. Two more come from
svg-icons, which checks every icon twice.
- e2e 57: ALL PASSED, 12 checks, 5 new (57e to 57g)
- Counter-checks work. Without the layout fix 57g fails. Picking
objects the dropdown does not offer fails 2 tests. Writing on
cancel fails 2 more.

Recurring cleanup round over the code since round 7 (bc688f3). The
issue now also asks to fix bugs and small inconsistencies found on the
way, so unlike the rounds before, this one changes behaviour in a few
places. Duplicated code in api went from 23 clones with 228 lines to
none (jscpd, at least 50 tokens). In src it stays at 22 clones with
271 lines, the same before and after.
Bugs:
- nginx served project and snapshot files as they were, so anyone who
knew a project id could read it without signing in. Every file the
API writes now goes through AtomicFile (temp file, mode, rename).
Projects, snapshots, releases, accounts and sessions are 0640, and
nginx answers 403 for them.
- Any signed-in account could delete a shared image, font or sound,
which projects of other accounts may wear. Deleting one is now for
administrators only. The editor never deleted a file, so the
client's delete is gone.
- Two saves of one project could run at once. The lock file was
removed after each save, so a waiting save and the next one locked
different files. The lock file now stays, and deleting a project
takes the lock as well.
- Bytes that are no picture got a 500 instead of a 422, because the
error handler also threw for warnings silenced with @.
- A session file was rewritten in place. A request reading it at that
moment found it empty and was signed out. It is replaced atomically.
- Delete did nothing for a shape picked in the vector art list. Delete
now goes through removeSelection, one case per kind of selection,
and a kind without a case fails the type check.
Inconsistencies:
- Escape on a question does what its Cancel does. Cancel on "Delete
project?" and "Restore snapshot?" leads back to the picker or the
list like the other questions did, and so does deleting a project.
- Editor texts use American spelling throughout, like the port names:
48 British spellings in 45 lines (colour, centre, initialised).
- objectName and groupName replace eleven copies of "own name, else
the asset's" and three of "Group". One copy fell back to the object
id instead of "?".
Duplicates, dead code, comments:
- routeFiles serves images, fonts and sounds instead of three copies.
HashedFileStore holds what the three stores shared: keeping a file
under its hash with its name, listing and deleting. The stores keep
only which bytes they take and what a record says.
- AtomicFile replaces nine copies of temp file plus rename.
- removeShapes is the one way the canvas, the inspector button and
Delete take shapes out.
- GraphInterpreter.fire was called by tests only. The 54 calls use a
helper in tests/helpers.ts now.
- FileStore.delete, HttpFileStore.delete and the PluginApi type were
unused. A doc comment in actions.ts sat above the wrong function.
Checked and left as is:
- solidCells is used by tests only. It is the per-cell view before the
merge into rectangles, the one place the largest-scale rule shows.
- An undo checker ran all 124 commands of the unit tests and compared
the project before and after undo. The only differences are empty
ports, groups and notes lists where there were none, which the file
format drops anyway.
Docs:
- README: the check sum.
- Wiki, own commit: API (admin-only deletes, 422, file modes, lock
file), Home (the "Not yet" list named three things that exist),
Concepts, Keyboard, Vector art, Architecture and Development, and
the 38 characters Gitea flagged as ambiguous on eight pages.
- .gitignore: the lock files, and pasted-*.png in any folder, which
keeps the screenshot archive out.
Tests:
- ./check.sh: 195 files, 2817 tests, exit 0 (+2 for the name helpers).
- PHP: accounts 52 in the web container and 53 in the CI image with
the race test (+2), snapshots 15 (+1), releases 20.
- Full e2e run: ALL PASSED, 1586 checks (+6 in 12, 47, 49 and 50).
- Smokes jumprun, tetris, actor: 24, 19 and 21 checks. The example
project files were restored byte for byte afterwards.
- The file stores of HEAD and of this commit give byte-identical
output for the live folders and for store, list and delete in a
throwaway folder.
- Counter-checks, all fail as expected: a 500 for bad bytes fails 12,
no admin check fails 49, removing the lock file again loses saves
in 3 of 3 runs (151 to 170 of 321), Delete ignoring shapes fails 47,
Escape that only closes fails 50, and dropping the shape case fails
the type check (TS2366).

Recurring cleanup round over the code since round 6 (056a622), 105
commits. Behaviour is unchanged. Duplicated code in src went from 29
clones with 229 lines (0.32 %) to 14 clones with 109 lines (0.15 %),
measured with jscpd and the same settings as round 6.
- BehaviorSystem.ts shrinks from 941 to 589 lines. Collecting the
pulses (keys, timers, collisions, animations) moved to
behaviorPulses.ts. The NodeContext the nodes receive moved to
behaviorContext.ts. Imports from outside stay the same, TimeScaled
is still exported from BehaviorSystem.ts.
- PointKindButton and drawPointGrip replace the "Point:" button with
its menu and the point and handle drawing that the curve and the
vector art tab each had on their own.
- lerpVec, cubicAt and splitCubic in src/core/util/vec.ts replace four
copies of the cubic curve and two de Casteljau splits.
- mapNested in Properties.ts is the one walk over lists and structs
that liveObjects and objectRefs did separately. withFieldRenamed
and withoutField replace three copies of renaming a struct field
and two of removing one.
- jsonBody and staleRevision build the JSON body and turn a 409 into
StaleRevisionError for all stores. The auth store turns a 401 into
its error in one place.
- Smaller helpers: structAssetFrom for the two "Make struct type"
commands, shownObject in the inspector, selectedItem for the size
gizmo and the polygon corners, solidTiles in the tilemap collision,
requireVariablesAsset and requireBehaviorVariable.
- Left as is on purpose: the plain forwarding from the collision and
physics systems to Solids, the pointer wiring of the canvases and
the identical last lines of the two make commands.
- Removed unused code: tilemapTileIds and tilemapsUsing were never
called since #128 and #131. EditorState.runtimeProject became unused
with GameRun in #266. The assetId getter of the make commands was
read only by a test.
- 60 values used only in their own file lost their export. The shader
and particle node catalogues stay exported as in round 6.
- Five comments that told history now describe the current state. The
doc comment of BehaviorSystem sits on the class again.
- README lists the struct, clip area and curve assets and mentions the
game link from #266.
Findings:
- Deleting a tile that is painted on a tilemap leaves its cells in
place, and they draw nothing. The delete dialog does not mention the
tilemaps. That was probably the job of the unused tilemapsUsing.
Left as is, because fixing it changes behaviour.
- The solid filter for tile surfaces was untested. A bent filter
stayed green. A new test in tests/core/surface.test.ts now fails
against it.
Tests:
- ./check.sh: 195 files, 2815 tests, exit 0 (one test removed with
tilemapsUsing, one added for tile surfaces).
- Full e2e run: ALL PASSED, 1580 checks.
- Smokes jumprun, tetris, actor: 24, 19 and 21 checks, all passed.
The example project files were restored byte for byte afterwards.
- Counter-checks, 12, all fail as expected: 10 in unit tests (among
them mapNested, splitCubic, cubicAt, staleRevision, the stay pulse,
the late timer and the time scale), 2 in the browser (Point button
always enabled fails 47, selectedItem without a hit fails 29).

An Object variable could only be set by a graph while the game runs.
A placed object always showed "(null)", although the other objects of
its scene are there to choose from and the runtime can already find
any object by its id. Now the placed object stores a reference to one
of them, and the running game turns it into the real object.
- Stored as {"$object": "<id>"}. The empty placeholder stays as it
was, so old projects load unchanged and empty still means "(null)".
- The row of an Object variable on a placed object is a dropdown with
None and every object of the scene, indented like the Hierarchy.
The same goes for Object fields in structs and Object items in
lists, also in the Variables and List tabs.
- The behavior asset keeps "(null)". An asset has no scene, so "Apply
to asset" is gone from Object rows.
- The runtime resolves the reference when the Variables or Properties
node reads it. A destroyed target reads as null, a missing one shows
"(missing)" in the row.
- Inside a container only objects of the same container are offered.
The reference keeps the template id, so every placement finds its
own copy.
- Deleting the target clears the reference in the same undo step.
Paste points references inside the pasted group at the copies and
leaves outside references alone. Create container and Unpack carry
references along with the new ids.
- A value a graph writes while running stays in the run. The scene
keeps the picked object, also in "Run in editor".
Found on the way:
- Setting an override coerced every object slot to empty, in plain
values, struct fields and list items. The shared objectPlace() now
keeps the reference.
Not done:
- No eyedropper to pick in the scene, the dropdown is enough for now.
- Deleting a template object in the container editor does not clean up
references in other scenes. They read as null there.
Tests:
- ./check.sh: 187 files, 2724 tests, CHECK EXIT 0
- e2e 1-9, 51, 57: ALL PASSED, 389 checks
- e2e 1, 57 on the final bundle: ALL PASSED, 17 checks
- 13 unit tests in object-references.test.ts, 5 checks in e2e 57
- Counter-checks: 8 unit breaks fail their tests, the browser break
without a pick list fails 57b-57d
