Model
- All models in a game are scans of us, our relatives and friends
- Scans of models and animations made with two Kinects + ReconstructMe
AI Behaviour Trees
AI
We used Behaviour Trees for almost everything: Player characters behaviours
NPC behaviours
Simple cutscenes
Programmer: node preparation Designer: composition and configuration of tree Large library of behaviours
Life parameters
Every person is described with several parameters(hunger, power, wounds, sickness etc.)
Mutual influence Parameter value → person state Deterioration of states
Life parameters
Emotions
People react to events Two perspectives:
– Participant of event
– Observer of event
Trauma – emotional reaction
Character and Psyche
Individual reaction based on character Psyche evolution
Data sheets
Technically emotional parameters form large multidimensional matrix
We were loading them from data sheets Its far easier for designers to work on data
sheets instead of windows in editor Designer can implement additional rules and
dependencies in data sheet by himself
World
We separate work of designers and artist while building scenes
Functional prototype

NPC placing + Smart Items
