Let a joint glide on a rail and drive it with a motor (#154)
Step 2 of the joints: a door that opens by itself, a lift and a piston need a joint that slides along one line and a motor that turns or pushes. A graph also needs to read how far such a joint stands. - Slider: a fifth joint type on Rapier's prismatic joint. Its rail is the joint's own x axis, so turning the joint turns the rail. Joints now carry Scale, Rotation and Mirror like a sprite. - Limit distance with Min and Max, in world units from where the object was placed. - Motor on hinge and slider: Off, Speed or Target, with Motor speed, Motor target and Max force (0 = no limit). Target goes there at no more than the speed and slows down for the last stretch. - Changing speed, target or force keeps the engine joint. Switching the motor on or off builds it again. - New node Joint position: value and speed of a hinge (degrees, counting past a full round) or a slider (world units). - Scene view draws a slider's rail dashed, with a tick at each limit. - shownFor in the schema takes a list of choices that must all hold. Findings, measured with a probe against Rapier 0.20: - A prismatic joint holds both bodies at one angle. Held to the scene or to an object without a rigidbody, the joint's own anchor body is turned by the placed difference, so nothing jumps. Between two rigidbodies the held one is turned to match, and the console says so once. - Rapier reads no joint angle back. The position is worked out from the two bodies. - A hinge motor is weak on a small body at the end of a long arm (box 20 on an arm of 100 does not lift itself). More solver iterations would help but cost every scene. A door of 100 x 20 reaches -90 and holds it. This is written in the wiki. Tests: - Unit: 16 new in joints.test.ts, 1 in joint-links, 3 catalog cases. - e2e 41: 27 checks (25 + 2), block 41f with a real mouse in the inspector and the motor in play (59.1 of 60 units in 1 s). - 9 of 9 unit counter-probes fail as they should. - Gate: 220 files, 3436 tests (3416 + 20), CHECK EXIT 0. - e2e total 1701 is counted (1699 + 2), the full suite did not run.

Tie two objects with a hinge, a spring, a rope or for good (#154)
Two bodies could not be connected: no door on a hinge, no lamp on
a rope, no wheel on an axle. This is the first step of the issue,
the four joints without a motor. The slider and the motors follow
in a second step under the same issue.
- Joint is a new asset type, placed as a child of the object it
holds, like a collider or a rigidbody. "Add joint…" in the
object menu makes one or places one the project has. An object
takes as many as it needs.
- Where the joint sits is the point it holds its object at. A
hinge and a fixed joint have that one point only. A spring and a
rope end at a connected anchor on the other object, counted in
that object's own units, or in the scene's without one.
- The rows follow the type: length, stiffness and damping for a
spring, length for a rope, an angle limit for a hinge. Length 0
takes the distance the two ends were placed at. The limit counts
from how the two were placed.
- The connected object is an object reference in the schema of the
type. Pasting, containers and removing treat it as they treat
every reference since #258.
- shownFor is a new schema option: a row is shown while an enum of
the same bag holds one of the named values.
- The object needs a rigidbody, its own or one further up. Without
one the joint holds nothing and the console says so once.
- A connected object without a rigidbody is a moving anchor: the
joint has a kinematic body of its own that follows it.
- A connected object destroyed while playing makes the joint let go
with a hint. Removed in the editor the reference empties, so the
joint holds on to the scene. The issue asked for "inactive" there.
- "Add joint" ties two objects while the game runs, from a joint
asset as the template. Destroy on the joint lets go, there is no
Break joint node. Destroy with keep children takes the joints
along with the object.
- The scene view draws a line from each joint to what it holds on
to and rings the held point. A selected spring or rope has a
round handle on its far end, and dragging it is one undo step.
- Joints hold in Play only. The editor run simulates nothing
(#148), and the inspector of a placed joint says so.
- Rapier counts a revolute joint's limits absolutely, not from the
start, so the placed angle is added. Measured with a probe.
- The + menu has 25 types now and no longer fits under its button
on a canvas 800 high. It scrolls there, and e2e 04 scrolls to
the last entry instead of expecting it in view.
Tests:
- Gate on melektaus-atx for this state: 218 files, 3390 tests
(3336 + 54), exit 0.
- e2e 1-16,24,39-46,51,52,57,58 on melektaus-atx: 831 checks, all
pass. Module 41 alone: 25 checks (21 + 4).
- 54 new unit tests: 40 in joints.test.ts (rope, spring, pendulum,
limit, fixed, the other end, the node, containers, paste), 6 for
the line the scene view draws, 4 catalog cases of the node. The
remaining 4 come from tests that make a case per asset type.
- Four new e2e checks in module 41: Add joint from the menu, the
rope to the hook with its line and handle, dragging the handle
with one undo, the bob hanging in Play next to one that falls.
- e2e 04, 40 and 46 count the new type in their lists.
- 21 of 22 unit counter-probes fail their tests. The other one is
equivalent: Rapier ignores removing a joint that left with its
body, the guard stays.
- Three browser counter-probes fail their checks (2, 1 and 2).
- One screenshot looked at: icon, line, handle and the rope rows.
- The e2e sum of 1691 is counted (1687 + 4, 1687 measured by CI

Wait for the dragged body before checking the hold in e2e 41 (#282)
The drag check in e2e 41 was red about every other run under WSL and twice on stein2. The diagnosis in the issue was wrong: "held" were not two samples but the first and the last one, and -3475 is the height of the ninth of ten moves. The last move reaches the body a few frames later (preview, physics step, drawn one step behind). Reading right after the move sometimes beat it, and slower frames under WSL made that likely. - The check first waits until the crate is at the pointer, for at most 2 s. If it never gets there, the check fails with "arrived: false" instead of stopping the run. - The page then records the crate's height in every frame and the check fetches the samples once. The count follows the frames, not the CDP round trips, and the check asks for at least 30 held frames. - Held and released samples are split by page timestamps taken right before and after the mouse release. "Fell" is the last sample within 200 ms of letting go. Tests: - e2e 41 on melektaus-atx (WSL): 6 of 6 runs ALL PASSED, 21 checks, 59 to 64 held frames. - Gate on melektaus-atx: 195 files, 2827 tests, CHECK EXIT 0. - Counter-check: without passing the hold to the world the crate stays on the ground and the check fails. - Not caught by this check: a body let go without zeroing its speed. After a second of holding the speed is 0 anyway. The unit test "grab too short for a physics step" covers it, as before. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Keep a dragged rigidbody on the mouse while the game plays
Dragging a sprite with a dynamic rigidbody in the scene view during play barely moved it. Only a quick drag and release got through. A dragged object should follow the mouse as if it had no rigidbody and start from rest when it is let go. - The scene view reports the dragged objects as held through EditorState. The game tick no longer writes its own position over a drag position that has not been read in yet. This affected every object in play, not only rigidbodies. - A held dynamic body turns kinematic and is set straight to the drag target. Gravity and velocity no longer pull it away between two mouse moves, and the "moved directly" warning stays quiet. - A body counts as held when the object itself, an object above it or its rigidbody is dragged. - On release the body turns dynamic again with linear and angular velocity set to 0. Not changed: a press on an unselected crate still lands on its same-sized collider (rule from #203). Dragging while play is paused and in the editor run is untouched. Tests: - ./check.sh: 155 files, 2273 tests, CHECK EXIT 0 (before 2271). - e2e 41 alone: 21 checks. e2e 1-16,39-43: 641 checks, all passed. - 2 unit tests: a held body stays where the drag puts it and starts from rest, also for a grip shorter than one physics step. The tick does not overwrite a drag position that is not read in yet. - 1 e2e check in 41b: the crate is lifted 150 units with the real mouse, holds exactly at -3490 for a second, then falls from rest (1.3 px, then 5.1 px) with an empty log. - Counter-checks: without holding in physics the crate falls back to the ground and the old warning shows. With the tick writing back the unit test fails. Without zeroing, a short grip keeps 490 px/s and the test fails. - Check total 1356 + 1 = 1357, calculated.

Draw scene symbols as white panel icons that make room for each other
The scene view drew its symbols from its own SVGs, each in a type colour and some on a plate. They looked heavier than the panel icons and were hard to read on busy ground. Symbols of different objects also sat on top of each other whenever their positions met. - Every symbol is now the panel icon of its kind, one file for both places. The scene-only SVGs in src/viewport/icons are gone. - Symbols are white in a thin dark outline with no plate behind them. haloSvg widens each shape of the file by its own stroke and draws that silhouette dark under the icon, so no second file is needed. - A butt stroke end would leave its end without outline. The halo caps such strokes square, and the rigidbody arrow shaft is now a filled rect so its top edge is outlined exactly. - Symbols are 18 world units across, stay upright and are clickable. A click selects the object, a drag moves it. - symbolLayout places every symbol on its object's position. Symbols that overlap stand on a ring round the middle of their positions, evenly spaced one icon apart. A ring that reaches into another symbol takes it in until nothing overlaps. Ownership plays no part. - Names sit beside their symbol, on the outside of a ring. Selection frames and parent links follow the symbol. - A collider icon no longer shows trigger or invalid state. The outline colour of the shape still does. - A lone collider sits on its sprite's middle again. A press there on an unselected sprite drags the collider, so e2e 02 and 16 now grab the sprite beside its middle. Hook __gm.container.objectRect helps 16 find that spot. Tests: - check.sh: 2245 tests, CHECK EXIT 0 (+8 for layout and halo) - e2e 1-16,31,39-43: 670 PASS, 2 FAIL. Both were sampling too strictly for the thinner, smaller icons. 5c looked for the exact outline colour, which the thin outline only reaches blended at this zoom. 31n started the ring scan one pixel past the smaller ring. Both are fixed, and e2e 5,31 then passed with 48 checks. - 5c checks white with an outline and none of the old colours, 41b checks the ring positions and that a click on a symbol selects its object, 31n checks the now white particle ring. - Counter-checks: without the halo only 5c fails, also with the looser outline match. Without the layout the ring and click checks in 41b fail. Originals restored by cmp. - The e2e check total stays 1351. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Show a clickable symbol for colliders in the scene view
Colliders were the only placed part without a symbol in the scene view. A collider that sits exactly on its sprite was hard to find and could only be picked by its outline. - The symbol is the box with four corner handles from the asset panel. It stays upright and has a fixed size in world units. - colliderColor() holds the colour rule of the outline (green, trigger colour, red for a shape that collides with nothing). The outline and the symbol share it. - The symbol sits 28 units left of the collider centre. The sprite centre stays free for grabbing the sprite, and a rigidbody symbol on the same spot is not covered. - The symbol has its own 26x26 hit area and the outline's handler. A click selects the collider and a drag moves it. sceneStack counts it as a hit under the pointer. - The hook __gm.sceneIcon(id) also returns x, y, color, screen and clickable. Findings: - With the clickable symbol on the sprite centre, four checks in 01 and 09 dragged the collider instead of the crate. That is why the symbol moved beside the centre. Tests: - ./check.sh: 153 files, 2237 tests, CHECK EXIT 0 (was 152 / 2234). - New unit test for colliderColor. svg-icons.test.ts lists the collider symbol. - e2e 41b: 3 new checks (beside the centre without and with a rigidbody, click selects the collider). - e2e 1-16,39-43: ALL PASSED, 635 checks. e2e 41 alone: 20 checks. - Counter-probes: no symbol fails both placement checks. A symbol without hit area fails only the click check. - Check total 1348 + 3 = 1351, computed, not yet measured by CI. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Pick an existing collider or rigidbody from the object menu (#222)
"Add collider" and "Add rigidbody" could only create a fresh asset.
Reusing one meant creating a copy by hand, and a new box collider
never matched the sprite it was added to.
- "Add collider…" and "Add rigidbody…" open a second menu at the same
spot: a search field, "Create new …", a separator, then every asset
of that kind sorted by name. Enter takes the first match.
- An existing asset is placed as a shared child, not copied. An asset
the object already carries is greyed out.
- The rule for when the entries are available lives in one place in
the collider commands. An object without a resolvable asset is
greyed out again, as with the old canAddCollider.
- "Fit to sprite" in the menu of a placed collider sizes it to its
sprite and centres it (position 0,0, z kept) as one undo step.
- Fit writes overrides of that placement, not the asset, because a
collider can now sit on several sprites. A value equal to the asset
value clears the override instead.
- Fit removes the collider's own scale, swaps width and height near
90 degrees and gives a circle the radius that fits (min/2). It is
greyed out for polygon and frame outlines and off a sprite.
- Menu has no submenus, so a second menu opens instead, similar to
"Add Component" in Unity. That costs one click more than before.
Tests:
- ./check.sh: 152 files, 2234 tests, CHECK EXIT 0 (before 151/2228).
- 6 new unit tests in tests/core/collider-parts.test.ts.
- 3 new e2e checks in 08a: submenu with search and greying, an
existing collider via search and Enter, Fit on oc2.
- 09, 40 and 41 follow the new labels.
- e2e 1-16,39-41 on the final build: ALL PASSED, 596 checks.
- Counter-checks: no greying, existing asset ignored and fit without
centring each fail at their own check. Breaking the override rule
fails 2 unit tests.
- CI confirmed 1345 checks at

One-way platforms, raycast and collision stay with contact data: a collider can be one-way with a side it blocks from (turning with its object, drawn thick in the scene view) and a tile can be one-way from above, one-way cells never merge with solid tiles, a contact blocks only when its normal is within 45 degrees of the blocking side, the new node Ignore one-way lets an object drop through for a while, and it all holds for Move and for dynamic bodies in Rapier, where the decision is made before each step because the hook may not touch the engine (#155); the new Raycast node answers hit, object, collider, point, normal and distance in our own f64 geometry, the same in editor run and play, and the editor run draws each ray for 0.25 s (#153); On collision stay gains an interval with its own clock per pair, and stay and enter gain the contact point next to normal and impulse (#149); fixes that every Rapier collider of a tilemap had the shape of its last cell

Move with collision reacts along the contact normal: it travels to the surface, stays flush and slides the rest of the move along it with Coulomb friction (the mean of both colliders, a tile counts as 0.5), a circle now rolls over an edge instead of catching on it, pushed dynamic bodies move off along the normal, Move gains the outputs hit, normal x and normal y, an object without its own collider moves freely, and editor run and play share the same path through Solids; contact point and normal come from our own f64 geometry (contactBetween), because Rapier's castShape lands 3e-6 px inside the wall in f32 (#150)

e2e 41b finds the ball's bounces by its turning points instead of frames within a pixel of the ground: the ball lands at ~9 px per frame, so whether a drawn frame catches the landing depended on where it fell between two physics steps, and CI missed the first landing and read the second bounce as the first (#147)

Set gravity survives a re-read of the model during play: World.setSceneProp remembers what the run itself set on the scene and syncFromModel lays it back over the copied scene props, so a project event mid-play no longer resets the gravity to the saved 980; the unit test re-reads the model mid-run and e2e 41c forces a project event right after play starts (#147)

Physics stage 1b: six new nodes act on dynamic bodies in play (Apply force over the frame, independent of the frame rate, Apply impulse, Set velocity, Set angular velocity, Get velocity, Set gravity for the rest of the run), a node on an object without a dynamic body and moving a dynamic body directly each log a hint once per object, and Move with collision now pushes dynamic bodies with a mass-dependent push while the mover stays flush; Move keeps its own move-and-slide instead of Rapier's character controller, which measurably snags on seams between colliders (#147)

Physics stage 1a runs on Rapier: a new Rigidbody child object (body type, mass, gravity scale, damping, fixed rotation, CCD) makes its parent fall, bounce and come to rest in play, colliders gain friction, bounciness and density, the scene gains gravity (0, 980), the new PhysicsSystem steps at a fixed 60 Hz with interpolation in world coordinates and treats a tilemap as static ground, On collision enter gains normal and impulse, play waits for Rapier and does not start without it, and the editor run keeps the old CollisionSystem; the existing collision tests run against both systems unchanged (#146)

Rapier 2D (@dimforge/rapier2d-compat 0.20) comes in as the physics engine: the editor loads it once in the background right after opening a project from its own chunk, so the main bundle grows by 0.19 KB gzip and the first frame does not wait; loadPhysics, physicsStatus and the 100 px = 1 m conversion live in src/runtime/physics/engine.ts, __gm.physics() reports the state, unit tests pin free fall and a box resting on a box, and e2e module 41 pins that Rapier is ready from its own chunk without console noise (#145)
