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.

A behavior could move sprites around but had no way to look at or
change the tilemap it was standing on. Doors, breakable blocks and
"is there ground ahead?" checks all need that.
- New nodes Tile at, Set tile, World to cell and Cell to world. The
conversion honours position, rotation, scale and mirroring of the
placed map. A small Tile literal node lets a graph compare what it
read against a fixed tile.
- The layer is picked by name from all tilemap layers in the project
through a new field kind. "First layer" takes the map's first one.
Because layer is an input, a text can also be wired in.
- Each placement keeps only its edited cells in liveTilemap.ts,
layered over the asset's cells. A second placement of the same map
stays untouched, and the asset itself is never written.
- A read sees a Set tile from earlier in the same flow. Drawing picks
up the edit at once and neighbouring autotile edges adapt.
- Solids see the edits straight away, so a Move in the same frame
already hits the new cell. Rapier rebuilds its shapes on the next
step.
- After Stop the map is back to what was painted. The editor run shows
the edit in the scene view while it lasts and does not touch the
project.
- An unwired tilemap input means no map, like Get position. Cells
outside the grid are refused and done reports false.
Tests:
- ./check.sh: 155 files, 2271 tests, CHECK EXIT 0 (before 2245).
- tests/core/tile-access.test.ts (14), one physics test for a floor
set at runtime, catalog entries for the five nodes.
- e2e 39,40: all passed, 86 checks (before 81), five new in 40s.
- Counter-checks: collision ignoring edits fails 3 unit tests, the
solids cache missing same-tick edits fails only the "at once" test,
drawing ignoring edits fails the 2 drawing checks, the editor run
not reporting a new tile fails only its check.
- 40s uses a still tile. The animated fixture tile redraws every frame
and hid the last counter-check at first.
- Check total 1351 + 5 = 1356, computed. CI confirmed 1351 at cb32b4b.
