With the behaviors fixed, the scene Performance test still ran at
about 23 fps with 500 entities. The rest of the frame went to the
editor: every spawn or destroy rebuilt the hierarchy with all its
rows, redrew the scene view behind the game tab and refreshed every
panel. The game itself is cheap. What the panels show of it now
follows a preset in the project settings.
- New section While playing in the project settings with three
presets: Live, Balanced and Minimal. Every project reads as
Balanced, including those saved before the setting existed.
- Live keeps today's behavior. Balanced brings hierarchy and panel
values up to date 4 times a second and stops redrawing the hidden
scene view. Minimal updates hierarchy and values only on pause and
throttles the graph tabs as well.
- The graph and state machine tabs stay live under Balanced. At 4
updates a second the beads on exec edges stutter, and the tabs
draw only while on screen. This differs from the issue proposal.
- The game itself is never throttled. Pause, step and stop bring
every panel up to date at once, and a change of structure that
falls between two updates is kept for the next one.
- The rule lives in editor/playThrottle.ts as panelPolicy and
PanelClock. PlaySession asks it after every frame.
- Objects spawned at the top level go into a hierarchy group named
after their asset, so hundreds of gold pieces fold into one row.
Groups start folded.
Measured on a throwaway copy of Performance test, 3 s each, fps:
- About 500 entities: Live 38.6, Balanced 56, Minimal 60.6.
- About 315 entities: Live 56.9, Balanced 60.5, Minimal 60.6.
- p95 frame time at 500 entities: 60 ms, 41 ms and 23 ms.
Tests:
- ./check.sh: 193 files, 2799 tests, CHECK EXIT 0.
- GM_STEPS=1,18,59: ALL PASSED, 54 checks.
- Full e2e run (local): ALL PASSED, 1562 checks.
- tests/editor/play-throttle.test.ts: presets, update rates, kept
structure changes, flush, spawn group and loading old projects.
- New e2e module 59: preset chosen with the mouse, measured update
rates, scene view behind the game tab, Minimal with pause.
- Module 03 now expects spawned objects in their group row after the
next update.
- Counter-checks: 4 in unit tests and 2 in the browser, each failing
as expected.
