July

Wednesday 1st​

  • Cleaning up June notes
  • Cleaning up ReadLast/ReadFirst jobs
    • Unify into ReadIndex

    • sin/asin
    • cos/acos
    • cosh/acosh

      • Send event to all clients when player clicks done
      • Show indicator on overlay for who is done
    • Switch game mode when all players are done
  • Removed budget stuff from lobby
  • Slightly optimised bullet collision sweeps (early out when there are either no bullets or no colliders)

Saturday 4th​

  • Weekend project - completing SIMD port of lambert solver
    • Porting iterative methods, same approach for all:
      • Calculate which lanes are "active"
        • Exit if all lanes are inactive
      • Compute for all lanes
      • Update loop state only for active lanes
    • Porting tests
      • They all work first time!?
      • Adding fuzz test to compare with baseline
    • Updating porkchop generator to use new method

Monday 6th​

  • My monitor died :(
  • Created a script to populate a dropdown with planets
    • Filter based on scenario and team
    • Store scenario in ECS

Tuesday 7th​

  • Investigating styling issue in Dropdown
    • Need to specify a theme key for white
  • Raising planet selection event
  • Added camera controller locking, preventing switching focus
    • Use in spawn controller
    • Auto configuring orbit when planet is selected

Wednesday 8th​

  • Investigating broken drag axis for orbit editor
    • It's fine, just weird due to trying to render scene view and game view at the same time!
  • Fixing issue with grabbing editor handles causing orbit to change slightly
    • Capturing initial value and offset from mouse cursor, maintaining that error. This prevents an initial "jump" when first clicking
    • Apoapsis
    • Periapsis
    • Ascending node
    • Descending node
    • Slightly reducing the captured error every time the user inputs a change, hiding the error reduction inside the genuine input
      • Removed this
  • Debugging network serialisation issue
    • Bad Magic number on ship serialisation
  • Setting up spawning for ships
    • Track budgets on server
    • Check budget
    • Checking if planet is allowed for spawning for this team
    • Adding list of allowed planets per-team to scenario

Thursday 9th​

  • Expanding list of spawn planets in scenario into a proper spawn point spec
  • Spending ship value from team budget
  • Sending budget update
  • Sending initial message to set budgets at startup
  • Spawning a ship!!!!
    • Integrator error - missing planet?
    • NaN orbit pos/vel
    • Orbit elements are not serialised correctly
    • Now the sanity check on orbit data is failing?
      • More units tests
      • Check serializer byte alignment
      • Velocity data is position data!?
        • Not always. but velocity seems to be the one that's often/always broken

Friday 10th​

  • Adding TimeAtTrueAnomaly function
  • Using correct true anomaly for spawning
    • Correcting position calculation: parent state at time 0, orbiter state at time TA
  • HotStuff units are not network serialised properly
    • Writing serialisers for every one
    • Added a unit test that fails if a new type is added without a serialiser
  • Investigating orbit serialisation error
    • double sequences serialisers are heavily tested
    • Fuzzing orbit data roundtrip
      • No events
      • Events
    • Potential double free to array pool?
      • Yes! Fixed

Monday 13th​

  • Setting orbit relative to parent planet during spawning
  • Adding Done Spawning tracking
    • Checking all players
    • Exempting spectators (treat them as implicitly done)
    • Switch gameplay mode when done
    • It works!

Tuesday 14th​

  • Cleaning up some todos
  • Adding client side handling for refused spawn requests
  • Experimenting with Unity Animator to control UI error states

Wednesday 15th​

  • Continuing experiments with Animator for UI
    • Events are not reliable?
      • Layer weight must not be zero!
  • Building a card to show who we're waiting for during spawning
    • Spawn cards
    • Bind to players
    • Toggle card when player becomes ready
  • Adding PlayerAvatarTexture component
    • System to load avatars (e.g. from Steam) asynchronously

Thursday 16th​

Friday 17th​

Saturday 18th/Sunday 19th​

  • Messing with more raymarching plumes

Monday 20th​

  • Testing lobby with Unsteam lobby
    • Lobby is broken - probably an Unsteam bug?
    • Host is not added to their own lobby!
    • Fixing spawning panels disabling themselves and then never re-enabling themselves
  • Investigating index-out-of-range in integrator (major body)
    • tidal force calculating is returning NaN!
    • NaN in integrator due to bad engine burn, test ship has zero thrust!
    • Fixed burn scheduler to not create a burn if force or mass flow is zero
  • Fixing Unsteam lobby unable to set member data key
  • Cannot connect to KCP session
    • Auth problem?
    • Wrong address encoding
      • Steam uses user ID as address, this doesn't work for KCP!
    • Once in the game never loads - waiting for netid!=0 forever
      • This won't ever happen, because it's only zero after a player object is created
    • Need better handling for failure to connect:
      • Client needs to not hang forever
        • Returning to main menu
      • Server needs to notice someone failed to connect
  • Fixed lobby "ready" indicator showing the state for the local player for all players
  • Added an offline scene to the network manager - failing to connect moves to this scene

Tuesday 21st​

  • Refactoring connection process:
    • Moving spawn player process into custom network manager
  • Building a custom network manager for new spawn process

Wednesday 22nd​

  • Creating campaign/scenario list for lobby

    • Scenario element
    • Spawn scenario elements
    • Campaign title
    • Scenario title
    • Figuring out layout rules to list scenarios inside campaigns
    • Click scenarios
    • Scenario search
  • Big refactor, splitting campaigns and scenarios into separate assets
    • Fixing breakage
    • Creating scenario.json files

Thursday 23rd​

  • Refactoring campaign list UI to just be a scenario list
  • Adding filtering to scenario list
  • Using new scenario list in lobby
  • Creating some campaign files
    • Experimenting with procedural generation for NATO style tasking

Friday 24th​

  • Improving lobby
    • Scenario list panel outlines
    • Scenario title
    • Scenario briefing
  • Adding orbit preview for spawning
    • Create nbody rail behaviour

Monday 27th​

  • Investigating feasibility of weekend idea for Myriad.ECS foreign key entity joins: allow command buffer to sort archetypes/chunks. This might optimise data locality.
    • Implemented chunk sorting, but not exposed public API yet

Tuesday 28th​

  • Improving test coverage on HotStuff physics library
  • Investigating fast approximate assignment problem for gunnery
  • Adding dashed lines to NBody spawning preview
    • Line times are specified with soft_double (emulated f64 on GPU)

Wednesday 29th​

  • Building a simple missile/PD gun simulation, to test gunnery assignments
    • Full target assignment probably not needed
      • Missile PD can fire a salvo and wait to see if it works
      • Lasers fire until the target explodes (no travel time)
      • PD guns are always extremely short range, suboptimal but fast algorithm is ok
  • New UI base panel design

    • Multiple uploads issue
    • Tidal force is NaN (caused by zero thrust)
    • No default ship file created
    • Old lobby doesn't disappear with steam?
    • Client had all planets loaded (Steam only? Client only?)
  • Reduced size of some files (excessive textures)
  • Considering chunk sorting API while build runs
