adminandClaude Opus 5	010b6a7f6c	A state can transition to itself: make transition and a second click on the same state connects a self transition, taking it fires On state exited and then On state entered every time, for local and global machines, while Set state into the current state stays silent as before; only states may connect to themselves, every other node is still refused, one self transition per state; the loop is drawn over the middle of the top edge with its arrow pointing down and its name at the apex, the preview already shows it while armed, and the inspector lists it once under Transitions out; new test hook transitionLabelAt, e2e 26e5 (#163) ...

adminandClaude Opus 5	cc285af10a	Tabs are open documents: Scene, Game and Plugins stay as fixed tabs, every other asset opens in its own tab (double click or Enter in the asset panel, on creation, from the list button), several assets of one kind can be open at once, a tab is labelled with its kind dimmed before the name, cut at 160 px and renamed with its asset, closes with its x or a middle click and goes away when its asset is deleted; a tab always shows its own document instead of following the selection, the picker in the tab head is gone, zoom and scroll are kept per document for the session and dropped on close, a double click on a call node stays in the same tab with breadcrumbs per tab; one editor per kind is switched between documents, the placement rules live in the pure module documents.ts, and the test hook showTab stays as a compatibility path; new e2e module 44 documents (#171) ...

adminandClaude Opus 5	4f546c0e08	Number fields drop trailing zeros: formatNumber still rounds to at most 3 decimals and then removes zeros at the end, so 100.000 reads 100 and 0.500 reads 0.5, everywhere (inspector, graph and shader nodes, duration and fps in the animation and tile tabs); a field's own decimals is now an upper limit, stored values are unchanged, -0 still shows as 0, and the graph's separate integer rule is gone (#172) ...

adminandClaude Opus 5	47eea2f6e4	Each tilemap layer has its own Z: an offset added to the Z of the placed tilemap, like a child's Z to its parent, default 0 keeps the previous order (layers right after their map, in list order), a negative Z sorts a layer below the map, on a tie layers keep their list order and follow the hierarchy against other objects; editor scene and game use the same order through the new pure function drawSlots, a tilemap draws into one container per layer, and the tilemap panel gains a Z field for the selected layer with one undo step per change (#174) ...

adminandClaude Opus 5	5385d9e152	The one-way tolerance angle is a field: a one-way collider and a one-way tile gain One-way angle (0 to 90 degrees, default 45), a contact blocks when its normal is within that angle of the blocking side, without a value the limit is bit-identical to before, and the rule holds for Move, Raycast and dynamic bodies in Rapier; tiles with different angles never merge into one rectangle, the scene view draws the angle as a cone in the middle of the thick side, and the inspector shows Blocks from and One-way angle only while One-way is on, through the new schema option shownWith (#159) ...

adminandClaude Opus 5	d4ea04d4d6	The scene view outlines a tilemap's collision only along its outer edges: where two pieces meet, their shared stretch runs once in each direction and is not drawn, so an autotile lake is one outline without cross strokes at the quarters, merged rectangles of plain tiles and one-way tiles follow the same rule, the bridges from splitting concave outlines disappear and a piece doubled on two layers is outlined once; fill and collision stay as they were, and the result is cached per tilemap and rebuilt only when its collision data changes (#173) ...

adminandClaude Opus 5	6a31f5e0ad	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 ...

adminandClaude Opus 5	947a6b1977	Collision outlines for autotiles: a frame holds several outlines (click adds a corner to the active one, Ctrl/Cmd-click starts a new one, clicking another outline makes it active, Delete removes the active outline and never the frame in collision mode), an autotile's outlines are drawn over the whole block, cut at the quarters and each cell takes the pieces of exactly the quarters its image is made of, so edges, outer corners and notches follow automatically; a tile of the block with nothing drawn blocks fully, cells of only full quarters merge back into rectangles, collision scale does not apply to an outlined autotile, and the previous format with one flat outline still loads (#141) ...

adminandClaude Opus 5	32057a96fc	Physics stage 2: colliders gain the shapes capsule and polygon, a polygon keeps its corners in the property points, turns, scales and mirrors with its object and is edited in the scene view (drag a corner, click an edge to insert one, double-click to delete, at least three stay, each step one undo step), a concave polygon is split into convex parts, a self-intersecting one is drawn red and collides with nothing, Rapier gets a capsule and one convex collider per part on the same body, and Move and the editor run use our own f64 geometry for the new shapes, where on a tie between two normals the one that blocks the move least wins, so a box no longer stops at the foot of a slope (#151); first version of a collision outline per texture frame, edited in the texture tab with the new Collision toggle, which a plain tile blocks with instead of its rectangle (#141, to be reworked) ...

adminandClaude Opus 5	1b5e386b60	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) ...

adminandClaude Opus 5	328f978d3c	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) ...

adminandClaude Opus 5	78899b1ace	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) ...

adminandClaude Opus 5	d02bcca266	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) ...

adminandClaude Opus 5	0607221423	Autotile floor tiles take their inner quadrants rotated by half a tile and their inner corners from the upper right block tile, matching RPG Maker MZ (#118) ... The corner tables are now derived from rmmz_core.js (Tilemap._addAutotile, FLOOR_AUTOTILE_TABLE, WALL_AUTOTILE_TABLE): the fill quadrants are taken rotated by half a tile so that neighbouring tiles meet with the quarters that sit next to each other on the sheet, and the inner corners come from the upper right tile of the block, not the upper left one. A test pins the model against both MZ tables, generated from rmmz_core.js rather than typed out. The animation check in e2e module 39 read its four pixels one by one and could straddle a frame change; step and pixels are now read in a single call.

adminandClaude Fable 5.1	89c46c30a0	An animation is previewed above its timeline: the root at the playhead, drawn but never written (#99) ... The Animation tab shows the root asset over the timeline, with every row's value at the playhead written onto a copy of it – the sprite, text or container placed at the origin as a scene would place it, a scene as itself. Rows reach the root through that placed object and its children through the object's instance edits, the route a placed container's content takes, so the ids match what the runtime gives them. The runtime player and the preview evaluate a row through one function (trackWriteAt), relative rows included; past the end of a once-reset pass the preview shows the starting values, as the player would. Play, pause and the ruler drive the preview through the timeline's playhead; a drag pans, the wheel zooms, Centre frames it. The document is never touched and undo never hears of scrubbing. On animation finished no longer describes itself as hearing "a sprite of the owner". Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>	2026-09-16 21:00:18 +02:00
adminandClaude Opus 5	4ed2edd0f0	An animation is a value a graph can pick, and playing a running one makes it win again (#97) ... Play, Pause and Stop animation take the animation on a port instead of a fixed setting, fed by the new Animation literal or a list item tagged `$animation`. Playing an animation already running keeps its frame but counts it as started last, so turning back to a walk that never stopped shows that walk. The actor demo walks through one Play animation over `ItemAt(walk, facing)` again and stops every animation to stand. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-09-16 20:47:31 +02:00

adminandClaude Opus 5	193378e6a9	An animation is a timeline of rows over one asset, played on an object rather than worn as a picture (#97) ... Part (a) of the animation rework: model, commands, saving, runtime and nodes. - AnimationAsset holds a root (sprite, text, container or scene) and rows; a row keys one property of the root or of an object inside it, keys sit on whole frames. - The last key decides the length (its frame counts as a frame of its own). The playhead runs between frames, so numbers and colors blend every tick even at 10 fps; everything else holds. - Playback gains `once-reset`, which puts back what was there before the start. A row can be relative, adding to where its target stood. - Play / Pause / Stop animation act on an object; each instance plays on its own, the later start wins on a shared property, and a behavior writing the same property still writes last. - A sprite no longer wears an animation through `texture`. "Create animation from texture" builds a sprite plus a texture row keyed frame by frame instead. - The Animation tab shows a placeholder until the timeline editor (part b) lands.

adminandClaude Opus 5	bf0be66c9d	A frame with borders tiles unless told to stretch ... The fill of a sliced frame defaulted to `Stretch`. It is `Repeat` now, and the Fill dropdown lists `Repeat` first. The saved document keeps writing only the fill that differs from the default, so the key it carries is now `stretch`, and a frame without it repeats. A frame saved before with the key absent and meaning stretch would therefore tile; none of the stored projects has one - both sliced frames on the server carry `fill: "repeat"` explicitly, so they draw as before.

adminandClaude Opus 5	94a0a578ed	A border drawn in pixels is as wide as the texture says a pixel is, so a small sheet can frame a large sprite (#96) ... A sliced frame drew its borders one source pixel to one sprite unit. Pixel-art sheets are small: a 16px corner on a 400-unit button is a thin line, and the only way around it was a larger image. The texture now carries `Nine-slice scale` (default 1), next to `Filter`. It sets how many sprite units one border pixel takes, for every sliced frame of that texture. The UVs stay as they are - a corner shows the same pixels, only larger or smaller. When the sprite is too small for both borders they are still scaled down together, now starting from the scaled size. With `Repeat` the tile size scales too, otherwise a doubled border would sit beside a pattern of the old size. The value is a schema row, so inspector field, saving and undo come without their own code. Anything that is not a size above 0 reads as 1, and documents without it draw as before.

adminandClaude Fable 5.1	cc6db5f350	Three stores, three importers and three pickers that differ only in their type are one of each (#85) ... Refactoring round one: HttpFontStore/HttpSoundStore/HttpTextureStore collapse into a generic HttpFileStore over a FileStore contract; fontImport/soundImport/textureImport share assetImport with an ImportKind per sort; ImagePicker/FontPicker/SoundPicker sit on FilePicker and describe only their row. The group/comment drag logic leaves GraphCanvas for annotationDrag.ts (with its own unit test), declaredRows.ts replaces the duplicated row build in particles.ts and shaders.ts, and dead code in font/sound/compile/emission/transform/actions is gone.

adminandClaude Opus 5	36ccc7626f	A box drawn around a part of the graph is part of it, so a fit frames it and a band catches it (#95) ... Fit measured the nodes alone: a group drawn around them was cut off, and a graph holding nothing but a comment framed the empty origin. It now frames both sorts together. The rubber band ignored boxes entirely. It catches them now, into the *same* selection as the nodes — `nodeIds` and `annotationIds` side by side — so one drag moves all of it, one Delete removes all of it, and one undo takes it back. A box counts only when the band holds all of it, where a node counts on touching: a group wraps the nodes it holds and therefore overlaps every band drawn over any of them, and since it drags those nodes along, catching it by accident would be felt at once. A node inside a selected group is moved once, not twice — `travellers()` collects everything one gesture carries and lets each thing appear in it a single time.

TextureFrame carries optional `border` (left/right/top/bottom) and `fill` (stretch | repeat); absent keys mean "not sliced", so no format bump and undo restores the plain frame instead of four zeroes. The sliced sprite builds its own geometry instead of the shared UNIT_QUAD: a 4x4 grid, and for `repeat` one quad per tile carrying the frame cell's real UVs -- tiling in the geometry, not in the sampler, so a frame out of a sheet cannot pull its neighbour in. Above 64 tiles per axis it stretches, to bound the buffer. A sprite narrower than left+right scales both borders down together until the middle is exactly 0, so the corners meet at a seam and never overlap. The texture editor gets four draggable border lines plus the same four numbers in the inspector. Hit order is resize handles, then the lines, then the frame body -- handleAt reports 'move' anywhere inside a frame, so lines placed after it were unreachable.
