UNDER THE HOOD





.blend template





primitives

● root :● empty● connected to game logic sensor, controller &

actuators

● templates :● basic 2D shapes● basic 3D shapes● basic spotlight● copied via createCube, createSphere, etc





basic script

● main functions :● init(), called once● animate(), called at each frame

● required methods :● configure()

● gather objects● declare addons

● update()● prepare inputs● increment frameCount





architecture

● ProcessingBGE.py [core]:● singleton● manages:

● scene & template objects● inputs ( mouse, keyboard )● references to dynamically create objects● addons

● constants ( PI, ARROW_UP, etc )● user-defined variables

● ProcessingOSC.py [addon]:● singleton● OSC receivers and senders





FUTURE DEV





code > short term

FINISH THE BASICS!





code > mid term

● All major functionalities exposed:● Camera● Material● Armature● Physic● OpenGL● Sound● Video & image sequence export

● Librairies:● OSC in/out (started)● XML

● External resources:● Image● Video● Sound

integration

easy● New PBGE file : File > New PBGE● Examples: File > PBGE examples > [List of examples]

not so easy● Bar on top of text editor with PLAY / STOP button● Embed “help” scripts● GE window:

● Floating● Automatic open/close on play/stop● Non modal





FOR YOU?





audiences

● digital artists● familiar syntax ● easy entry into gaming development

● pro● prototyping speed increased

● amateur● easy access to RT features

● students● easy syntax● step by step examples
