Thomas Weber 925f113400 Don't start monitors if there are no targets 
Fixes https://github.com/TurboWarp/sb3fix/issues/125 in the safest way that
hopefully has no unforseen breakages on weird behaviors

Thomas Weber 52f4369e63 Fix spork compatibility issue with mutation-less control_stop 
Our editor relies on the mutation for control_stop to know if there is a connection below.
Spork does not export that mutation anymore.
Instead, we will just generate the mutation to fix errors on loading.

Classfied3D 94276b1ee9 fix indefinite calls to analyzeScript when a large amount of procedures interlink (#334) 2026-04-09 18:08:06 -05:00
Thomas Weber 9f2106a290 Remove variable value safe stringification 
I thought this may have been part of fixing a sb2 -> sb3 corruption issue.
But from commit log, it seems this was added to prevent extensions from making mistakes.
With the scratch-parser change, those mistakes are now considered features.
Seems safe to just do remove these checks all the time.
Closes https://github.com/TurboWarp/scratch-vm/pull/332

Thomas Weber 6abc33d787 Remove immutable.js (#329) 
Why:
* We use immutable.js 3.8.2 which is ancient and not getting updates
* immutable.js adds 55KB to the bundle, of which we use almost nothing
* immutable.js's treatment of 0 and -0 is nonsensical and would require weird workarounds like https://github.com/TurboWarp/scratch-vm/pull/320
* We don't benefit from the whole immutability thing

What we're doing instead:
* We have our own MonitorState and MonitorRecord classes
* We track dirty-ness at modification time instead of equality checking every tick
* scratch-gui and packager can continue to think we use immutable.js without causing issues in either direction
  * our objects have enough stubs that immutable.js-expecting consumers are ok
  * when receiving an object, we check if it looks like an immutable.js one and ask for the plain JS version so that works okay too

Thomas Weber c3a47de575 Fix incorrect type for looks_size 
It can return 0 when fencing is disabled
 2025-12-29 19:01:46 -06:00
Thomas Weber 7aa8930802 Fix incorrect types for sensing_of 
They can return 0 if the sprite does not exist
Fixes https://github.com/TurboWarp/scratch-vm/issues/262
Closes https://github.com/TurboWarp/scratch-vm/pull/325
(this one uses a different fix and has tests)

There are broader issues about compiled sensing_of not handling dynamic
sprite create/delete. We should tackle that later. The other PR wouldn't
really fix this either.

Thomas Weber 779f0a196d Add no-op rAF loop to improve frame pacing 
It is still not perfect. Better though
Fixes https://github.com/TurboWarp/scratch-vm/issues/257
Closes https://github.com/TurboWarp/scratch-vm/pull/324
(this one uses a different approach and restricts to 30 FPS and checks
if the platform is known to benefit before we turn on battery draining
workarounds)

8to16 36bf998aee Fix evalAndReturn with comments at the bottom of a script (#322) 
This is because beepbox's script:
https://cdn.jsdelivr.net/npm/beepbox@4.2.0/global/beepbox_synth.min.js
has a sourceMappingURL comment at the bottom for whatever
reason, causing it to become
//# sourceMappingURL=beepbox_synth.min.js.map;return beepbox;
This is obviously going to break and might also be the case with
other libraries too, hot just beepbox.
