A composition lost the first frames of a video item. Its clock ran
while the player was still loading, in the tab and in the game. The
game only waited for videos once, when it started. A composition that
a behavior starts later spawned its items after that wait.
- The view now records which video sprites it left out for lack of a
first picture, one entry per object.
- The composition tab holds its playhead while the preview misses a
video, for at most VIDEO_WAIT_MS (3 s) like the game.
- CompositionSystem holds a composition's clock while one of its live
items misses its video. The rest of the game keeps running.
- The editor play and the published game pass their view to the run
as RunServices.pictures.
- VIDEO_WAIT_MS moves to core/model/video.ts, because the runtime
does not import from viewport/.
- Videos loaded ahead for coming items do not hold the clock.
Items can now be copied and pasted inside the composition tab.
- Ctrl+C keeps the timing of the copied items next to the objects.
- Ctrl+V pastes objects and items in one undo step. The earliest item
lands at the frame under the pointer, on the track there.
- Without the pointer over the tracks it lands at the playhead, on the
selected track or on the top track of the selected items.
- Several items keep their distances and tracks to each other.
- The same copy pastes into a scene as plain objects. Objects copied
from a scene do not paste into a composition, they have no timing.
Tests:
- Unit composition-edit, clipboard, composition-play: 3 new for
pasting, 1 new for the clock waiting in the game
- e2e 69i (play from the end waits for the video), 69j (paste under
the pointer and at the playhead), 68d (a composition started from
On start waits for its video)
- each new check is red without its fix
- README: 2036 editor checks
