Tech Network One network manager per game instance Operates in client or server mode anytime Threaded message retrieval and separately threaded message parsing ! ! ,

Tech Settings We use persistent XML storage to minimise “magic numbers” Stores default values in case of XML file corruptions, a new one is created/loaded Settings files can be saved/loaded at run- time A single Settings Manager can be polled for retrieval of any settings values ! ! ! !

Tech Console In-game drop-down command console !

Tech Console In-game drop-down command console Allows run-time setting of values or calling of methods Can provide debug output ! ! 4

Tech Audio Split into multiple layers How do you keep them all sync? We play them all at the start and mute the ones we’re not using ! ! ! ! We cheat!

Tech Heartbeat Split into multiple layers Sprite sheet for blood vessel animation Scaled in code to simulate it beating = ! ! !

Tech Chase Fades between layers as heart beat decreases Also darkens lighting ! !

Tech Physics Solves the really hard problems for you If you can figure out how to make use of it with no documentation Abstracting for the rest of the team and defining fundamental data representation ? 8 , { Actors PhysicsActor Animatable definitions Interfaces

Tech Gameplay etc Biggest challenge is the state management — complex, lots of transitions, lots of edge cases Need for new stuff to have been delivered yesterday, other coders depend on new, untested code Great solution for state transitions — event- based system A lot of debug visualisations developed — helped massively in development !

Look at your source control, now back to Git (I’m on a horse)

! Thanks!
