The game uses a UDP-based protocol. Unlike TCP, UDP does not guarantee that
packets arrive, or that they arrive in the correct order. For this reason,
the game protocol implements those features using the following:
* All packets have a sequence number that is utilized for reordering
* Important packets are wrapped in a SlottedMetaPacket with a subslot number
* RelatedA packets ae used to request lost packets using the subslot number
* RelatedB packets are used to confirm received SlottedMetaPackets
All of these go both ways, server <-> client. We used to only partially
implement these features: Outgoing packet bundles used SMPs and could be
resent, but not all packets were bundled and there was no logic for requesting
lost packets from the client and there was no packet reordering, which resulted
in dire consequences in the case of packet loss (zoning failures, crashes and many
other odd bugs). This patch addresses all of these issues.
* Packet bundling: Packets are now automatically bundled and sent as
SlottedMetaPackets using a recurring timer. All manual bundling functionality
was removed.
* Packet reordering: Incoming packets, if received out of order, are stashed and
reordered. The maximum wait time for reordering is 20ms.
* Packet requesting: Missing SlottedMetaPackets are requested from the client.
* PacketCoding refactor: Dropped confusing packet container types. Fixes#5.
* Crypto rewrite: PSCrypto is based on a ancient buggy version of cryptopp.
Updating to a current version was not possible because it removed the
MD5-MAC algorithm. For more details, see Md5Mac.scala.
This patch replaces PSCrypto with native Scala code.
* Added two new actors:
* SocketActor: A simple typed UDP socket actor
* MiddlewareActor: The old session pipeline greatly simplified into a
typed actor that does most of the things mentioned above.
* Begun work on a headless client
* Fixed anniversary gun breaking stamina regen
* Resolved a few sentry errors
* object registration adjustments for players and avatars and lockers (especially lockers)
* refactored locker container
* modifications to fields and method names for guid-related files; SpecificNumberSource created
* locker item display; proper item insertion into locker-space and searchability of that locker-space
* proper item removal from locker-space, including swap-items on other insertion tasks
* comments and tests; adjusted avatar/player registrations; allowed for restriction in the SpecificNumberSource; renamed CataloguedInventory to LocallyRegisteredInventory, and made internal object registration work
* accommodations for RequestDestroy, to allow the locker's Clear button to work; modification of expectation for resolving projectiles through ValidObject
* initial spiker logic for charging mechanic; it's functional but doesn't work exactly by the numbers say it should
* no damage degrade for radial damage; charge mode features, including damage on the projectile and fire mode on the weapon; the Spiker's damage output is pretty close to accurate
* ammunition drain timer works correctly; no need for the progress completion function; new formatting sucks
* dial back on fire mode changes; stop excessive weapon discharge case; comments
* master merge; test fix (when did it change?)
* test repair; fixed unintentional side-effect of instantiation of StanDamProf
* introduction of aggravated damage properties and modification of damage pathways such that 'aggravated' is treated as a unique damage type
* initial work and tests for AggravatedDamageMessage
* wrote aggravated damage properties into the definitions of projectiles that convey them; basic workflow for aggravation from projectile damage is in place, but not tested
* merge rebase resolutions
* grenade projectile flag on projectile definition; better timing control on aura behavior and integration with player control
* timing and damage tuning around: standard, reinforced, max; plasma grenades, dragon
* work on starfire damage profile; moved aura behavior into own folder and creates an aura container object; extended aura behavior to vehicles; applied target-control to aggravation effect
* woring Starfire damage calculations; projectiles have open-ended quality modifier
* working comet calculations
* separated aggravation behavior and uara management behavior; moved files into packages and deleted old files
* moved aggravation damage into damage implementations of turrets and vehicles, rather than directly into ther immediate control agencies; revamp projectile quality modifiers; comet now does initial damage and one less tick of aggravation; the implementation progression of damageable entities is different now
* eliminated multiple timers for a single aura effect; added comments; added tests; fixed tests
* aura effects that will run for longer will not get replaced by aura effects that would end sooner
* merge rebase; accommodation for suppressing aura where no aura should be displayed; new radial degrade calculations
* test repairs
* merge rebase hell
* dragon fireball burn damage modification
* fireball burn effect should always be 1 as long as it does damage, despite radial degrade
* Fix !list not distinguishing between players and corpses
* Fix /worldkick not working
* /silence no longer responds with a message window
* Fix 96-99 zone map files
* Fix implants not resetting after being jammend
* Fix MAXes requiring the wrong certs
* RefreshLoadouts no longer queries loadoads from the database
* /gmtell no longer sends to self
* Set AMS spawn timer to 10 seconds
* Fix medkit cooldown display
* Fix wrong max type being purchased
* Fix implants not being locked when fatigued
* Fix implants progress bar
* Make tells case insensitive
