0.3.0

  • oz
    • more C++11 features

    • new Time class
    • new StackTrace class (split from System class)
    • System::bell()
    • OutputStream is readable
    • new BufferStream class (OutputStream with dynamic internal storage)
    • File class: file type and size setting changed, added support for NaCl local filesystems
    • new PFile class: version of File class to act as PhysicsFS wrapper
    • Log supports operator << for printing streams
    • new JSON class for manipulating JSON files
    • Config class removed
    • clearmacros.hh header to undefine liboz macros that might conflict other libraries
    • can be compiled as a shared library
    • additional Linux dependency: PhysicsFS, optional dependency for Linux: libpulse-simple
    • better Win32 support, POSIX API replaced with Win32 API where possible
    • ported to NaCl
    • fully documented
    • ZLIB licence
  • common
    • new layer, split from matrix
    • Span and Timer classes moved to common from matrix
    • new Lingua class, gettext-like system, but modularised and suitable for data package system
  • matrix
    • BSPs, object classes, fragment pools, client imagos and audios are internally referenced by pointers or indices instead by strings, several lookup hashtables replaced by arrays
    • object attributes: tell what special abilities an object can have (nigh vision, binoculars, satnav, music player ...)
    • fragment pools: particle replacements; fragments can be configured like object classes, can have a graphic model assigned, etc.
    • keys: object can have assigned a key value, so it can lock/unlock matching structure entities
    • lava: can be used both in structures and terrain instead of sea
    • objects can be rotated around z axis in 90° steps
    • physics
      • object tracks lower entity: when an entity moves horizontally it also moves objects on top
      • sliding damage
      • configurable gravity
      • fine-tuning of constants and many small improvements and bugfixes
    • structures
      • crushing: structures fall into terrain, and crush objects in their way
      • bound objects: objects that are created together with a structure and destroyed with it; useful for defence turrets
      • air brushes to tag certain structure areas that should not be filled with water when the structure is under sea
      • sea brushes tag areas with the same content as terrain sea (including fog colour)
      • no more need for hull around BSPs
      • triggers: some entities can be activated; they can trigger themselves or other entities
      • entities can be locked/unlocked with appropriate key
      • manual doors
      • elevators
  • client
    • smooth loading: model loading split to preloading (mapping file to memory) that is run in a new thread and upload to graphic card that has to be synchronous with rendering
    • textures have 3 components: diffuse (base colour), masks (per-pixel specular and emission masks) and normal map
    • objects are filtered from rendering if aspect angle from eye is too small
    • configurable fog colour for both terrain and structure water/lava

      • MD2-like vertex animation integrated into Mesh class
    • offscreen rendering support
    • postprocessing, bloom postprocess effect
    • Camera class & proxies
      • smoothing of movement and rotation

      • CinematicProxy class for scripted camera movements, colours, music track setting ...
    • *Audio classes
      • footstep and swim sounds
      • filtering of high-frequency events
      • velocity is set for sound sources and listener
    • Sound class

    • no more encapsulating a BSP with a box
    • fragment pools and object classes are compiled
  • tools
    • ozGettext tool for extracting structure, entity, object names and strings from mission scripts for translation
    • ozManifest for generating package manifests for NaCl port
    • ozSineSample for generating src/oz/bellSample.inc
  • general
    • PhysicsFS used for accessing game data, so they can be loaded directly from archives
    • game data can be modularised into packages
