Update: PersistentObjectWorkQueue now gathers a bit more telemetry
- also fixes a potential bug with stale data uploading to our backend (another case in ObjectQueue)
There's a bug with it being desynced with the rest of the data (it's called last, but in reality is current), will fix later
Tests: none, not done yet
Update: runtime_profiler - track pre_lateupdate times
It's a category with a bunch of unity internal work that can take a non-trivial amount of time. Should make it easier to identify source of degradation.
Tests: dryrun of analytics in editor with runtime_profiling 1
Merge: from useplayertasks_removegroupoccludee_nre
- Bugfix: patch exception from double add of occlusion group member. OcclusionValidateGroups to validate if groups are correct
Tests: various 2p scenarios - being close, far, outside of range, teleports
Update: add OcclusionValidateGroups servervar
- also replaced the conditional log with a logerror, to make sure we spot it
- codegen
Couldn't reproduce the issue locally, so I'm missing something, including whether it was a false-positive or not. This should help check every bad case and confirm whether the issue is legit or not
Tests: used the command in a couple scenarios - players close, players far, players outside of network range, with invis on/off
Update: replace throw with a devbuild-conditional error log
This is a cirtical code path, so we can't interrupt it or we'll corrupt global state. Think I see where the problem is coming from, will attempt to fix next
Tests: none, trivial change
Merge: from playerinventory_oncycle_optim
- Optim: iterate over cached items with OnCycle callback (instead of searching for them every time).
Tests: ran unit tests
Optim: ItemContainer.OnCycle now uses cached list of items with a callback
- added a perf test of 300 containers with ~10% items with OnCycle callback
Goes from 0.179 ms down to 0.074ms(-58%) for 300 player inventories. Real world server's invoke times are 0.97ms for 171 inventories, so might need to move it out of invokes later.
Tests: ran unit test
Tests: add ItemContainer.TestOnCycle test
Tests: ran unit tests
Merge: from useplayertasks_removegroupoccludee_nre
- Optim: rewrote how we manage occlusion groups to reduce their overall number and added pooling
- Bugfix: UsePlayerUpdateJobs 2 - no longer send extra snapshots when players move across network grid
Tests: 2p on Craggy - tested all occlusion interactions(fly away-back, hide behind terrain, use helicopter). Tested moving across grid with disconnecting 2nd player and killing them, validated occlusion groups. Monitored pooling via print_memory ListHashSet
Bugfix: when player disconnects, ensure we destroy relevant occlusion groups
- destroy local group if no local participants present
- remove destroyed participant from other occlusion group member's groups
Tests: 2p on Craggy in different cells - get 2nd player to disconnect, then kill sleepers. 1st player walks into the cell - no more NREs. Ran usual occlusion checks (fly away and back, hide behind terrain)
Optim: use pooling for occlusion groups
- prealloc 2k groups in the pool (1 per player and sleeper)
Tests: 2p on Craggy - nocliping across various grid cells and checking print_memory stats
Optim: ServerOcclsuion - rewrite how we track occlusion groups
- also fixes server occlusion bug which sends out more snapshots than necessary
Previously every network group in subscription range of player would create an occlusion group. Now, only occlusion-enabled entities populate their local cells (and their subscriber's local cells) - se get activeplayer+sleepers count max of occlusion groups.
Tests: both in UsePlayerUpdateJobs 0 and 2, 2 players on Craggy - ran around across network cells, flew outside of network range, used minicopter to fly into network range, checked sleeper is visible, checked kills clean up internal state. Player got occluded over terrain.
Merge: from triggerparentdelayedexit_optim
- Nothing, this just fixes merge history to avoid showing it as a non-merged branch
Tests: none, no files changed
Merge: from useplayertasks_invisplayers
- Bugfix for invisible player in helis/other vehicles with UsePlayerUpdateJobs 2
Tests: 2p on Craggy, flew heli to player outside of network range 5 times - player was visible
Bugfix: UsePlayerUpdateJobs 2 - when player leaves occlusion group, clean up last visibility timestamps
- fixed whitespacing after merging messing it up in one of the files
This caused negative feedback loop. If EntityQueue doesn't send snapshot during network subscription change (because of OcclusionFrameCache), the ServerOcclusion should send it, but having an expired visibility timestamp meant it didn't send the snapshot (expired == previously visible, so snapshot already sent).
Tests: on Craggy with UsePlayerUpdateJobs 2 flew 2 players outside of network range, then made 2nd player fly in a minicopter to the 1st - was visible. Repeated this flight test 5 times - all passed.

Merge: from triggerparentdelayedexit_optim
- Optim: new TriggerParent volume processing mode, controlled by TriggerParent.TickMode (default to 1, old mode is 0). TickMode 1-specific optims controlled by UsePlayerV2Shortcuts and AllowTriggerSleeping switches (both enabled by default)
Tests: built boats, sank them while on them, spawned 100 boats with sleepers both with TickMode 0 and 1
Update: set TriggerParent.TickMode to 1 by default
- codegen
Tests: booted up craggy in editor, checked that it's set to 1 and called at boot
Merge: from main
Tests: compiles
Merge: from main
Tests: compiles
Clean: remove TriggerParentDelayedExit.allow_tick_skipping support
- codegen
Originally was an optim, but discovered that I had a bug that always stayed disabled. If we need it, I'll reimplement it for TickMode 1
Tests: compiles
Update: Tickmode 1 - add allowtriggersleeping optim killswitch
- codegen
Tests: built a boat, set tickmode 1, checked in profiler what runs. set AllowTriggerSleeping 0, checked profiler - it started running queries
Optim: TickMode 1 - allow triggers to sleep if they don't move on specific axis and internal entities also don't move on specific axis
- took out internals of BaseEntity.HasMovedInLS to BaseEntity.ComparePos(Vec3 from, to)
- Player Boats now set interest in XZ when alive, XYZ when sinking
- Buildfix for SERVER only code (whoops)
This brings 100 boat test to 0.25ms (down from 1.6ms, -85%), or down from 3.1ms, -92% from TickMode 0
Tests: built a boat, set tickmode 1, jumped on and off - got unparented. turned on the engine, jumped off - got unparented once in the water. noclipped above with engine on - got unparented after a delay. Spawned 100 boats.
Update: BaseEntity now remember it's last LS position and can report on which axis it has moved
- added unit test for it
Needed for upcoming parent trigger optim
Tests: ran unit test
Optim: reduce branching in BaseEntity.HasEntityInParents
Saves a tiny amount (60micros for 600 checks), but the change is relatively trivial and is used in a bunch of places
Tests: spawned 100 boats with 3 sleepers

Optim: TriggreParent.TickMode 1 - batch swimming checks
100 boats now take 1.6ms max (down from previous 2.1ms, -24%) vs 3.1ms (-49%) of TickMode 0.
Tests: built a boat, sank it by shooting, got unparented
Update: expose StableObjectCache internal T[]
- had to introduce approx equals to WaterInfo as unit tests were failing (why now?)
- consolidated common logic to fix missing shoreline check in batched version (we need unit tests as part of builds)
Need it to simplify code around water factor batching
Tests: unit tests
Update: adding a TODO to enable minor logic caching
Tests: none, trivial change
Merge: from triggerparentdelayedexit_optim
- Bugfix: added missing check in tickmode 1
- Bugfix: fixed TriggerParentDelayedExit cleanup logic disabling it's effects
- New: paste_line command
Tests: built a wonky ship with tickmode 1, jumped over it's gaps
Update: TriggerParentDelayedExit cleanup logic only runs when trigger is disabled
We always ran cleanup when OnEmpty got invoked, even if decided to delay the exit, which disabled delay functionality
Tests: built a wonky ship and jumped around gaps - parenting was in effect long enough
Bugfix: TickMode 1 - add missing overrideOtherTriggers check
Tests: none, trivial change
Update: remove dead vars and cache == null check
Tests: none, trivial change
Update: add paste_line <name> [count = 1] [offset = 1] - will spawn the clipboard in a line using player's facing with offset-sized spacing
- also if pasting players, make sure they run their ForceTriggerUpdate
- codegen
Tests: spawned a 100 boats in a line
Bugfix: TriggerParentDelayedExit::SupportsTickSkipping was always evaluating to false
- switched it to be off by default, as it was likely off during my earlier testing
Tests: none, trivial change
Merge: from triggerparentdelayedexit_teleport_fix
- Bugfix: teleporting from a player boat should no longer cause weird parenting issues
Tests: built a boat, teleported away - no weird movement afterwards
Bugfix: don't try to delay unparenting when teleporting away from the boat
Tests: built a small boat, spawned a player on it, turned on the engine, teleported away - didn't have the weird extra movement
Merge: from analytics_std_dev_fix
- Bugfix: fix for invalid std_dev calculation
Tests: none, trivial change
Update: always record high and low percentile telemetry for non-game mode
It's a smidge more data, but makes building dashboards easier
Tests: none, trivial change
Bugfix: fix std_dev that could generate NaNs via sqrt of a negative number
Tests: none, trivial change
Merge: from triggerparentdelayedexit_optim
- Bugfix: shooting a weapon can cause NREs on the client
Tests: shot in the sky with a bunch of bursts - no NREs
Bugfix: VerifyRays - avoid trying to read hit array outside of working area
I asssumed we always call it with tightly-sized arrays, but it's not the case on client
Tests: shot in the sky with a couple bursts - no NREs
Merge: from triggerparentdelayedexit_optim
- Optim: improve performance of GamePhysics.TraceRays family of queries
- Optim: TickMode 1 - add UsePlayerUpdateJobs2 related shortcuts to TriggerParent
Tests: built a boat with tickmode 1, spawned npc player on it, jumped on and off, flew in it's vicinity - no issues.
Optim: TraceRaysUnordered - optimize collider validation using burst jobs
- added UtilityJobs.FlipBoolJob and ScatterToJob<T>
This brings costs down across the board:
* 128 rays - 0.37ms -> 0.25ms, 33% improvement (serial was 0.49ms, 49%)
* 1k rays - 2.59ms -> 1ms, 61% (serial was 4.33ms, 77%)
* 8k rays - 18.9ms -> 6.26ms, 67% (serial was 34.79ms, 82%)
