GL HF

0.1.5

• fix change of placement mode when freeblocks are deleted (item -> free-ground, for example)

• many bugfixes

• lowerable update frequency

• player tag toggle

• expose settings prelim

to test:

• crash with many players for an extended period (ref count > 1 million issue)

• performance with 16+ players in a room over time (the 'lag' issue with long frames)

• is the server reliably sending msgs?

• desync detection + custom blocks/items (no loop, or other issues)

• calc fast shadows afer placing blocks

todo: recent:

• [ ]

• fix holding down x and not having things be changed on you

.0.1.5x

• server: map size, base/mood, car, rules_flags,

• create map base

• player join leave announcements (tmx together rip)

• status hud (processing updates) - pending updates hud

• disable sweeps

• server issue limiting to 25 blocks, only triggers more on update

• limited undo support

• svr: parallel reads / per player

• follow mode -- update camera to match user

• room options:

  • allow custom items
  • map base size
  • map mood
  • set car (stadium / rally / snow / desert)
  • block delete all

• reconnect to server issue on desync (then it rebuilds)

  • avoid rebuild (use autosave with sequence number?)
  • avoid needing to restart map at all (detect desync and reapply actions)

• grand2020: laggy when building together after a while

• (this is okay) test driving updates when you leave

• optimize loading prior map, break into chunks

• add autosave or saved map pre-upload / download to avoid replaying history

  • requires sequence numbers

• clear all locked down

• undo capacity for admin / mods

• skin sync

• tm2 map together

does it build entire map

what if 2 ppl load diff maps

• custom item uploads

• game crash on reload or joining room

• sync period where inputs are disabled

• seq numbers on packets

• rejoin from X spot

• separate loop for reading packets

• demarcate packets with start / end

  • 0x2a2a2a5452415453 (b"START***")
  • len: uint32
  • len: uint32 (repeated for packet framing) & 0xFFFFFF | (ty << 24)
  • check len & 0xFFFFFF are eq, and read type
  • 0x53444e452a2a2a2a (b"****ENDS")

• SIGNS FUCK EVERYTHING

• SnowRoadPillarStriaght

• RallCastleWallStraightPillar

• send custom items

• wait for blocks when entering editor mb?

• cursor and camera of other players

• deleting macroblock crashed game??

rules for mapping

• vanilla only (custom blocks / items possible but not supported)

• no media tracker

• validation isn't supported

• leaving test mode might cause updates

• skins not yet supported

• no undo / redo

• placing / deleting blocks will send them to the server, then undo them, then replay things in the right order (so everyone has the same map)

• no item editor

• need a feed of all objects placed/deleted

• can do E++ stuff by using MB to nudge, instead of modifying and refreshing -- that will be compatible with hooks

problems to solve

• finding blocks in large map:

  • points (not regions)
  • oct tree
  • expand as more blocks placed
  • faster duplicate block checks?
  • export from E++
  • tie into map cache and block/item hooks

• comparing maps to calculated spec

• finding differences between calculated and actual

  • use oct tree?

• undo

  • we have a local stack
  • need to ignore action from our undo queue
    • keep track of index?
    • ignore most recent flag
