[Robotics] Extension of the sensor/controller/actuator model in the GE

[Séverin Lemaignan]

Hello Benoit!

Thank you very much for this in depth coverage of what can be done or 
not with logic bricks.

I've copied your mail on the wiki for the record 
(http://wiki.blender.org/index.php/Robotics:Sensors%2C_Controllers%2C_Actuators_architecture_in_the_GameEngine)

It somehow confirm my current perception of the logic bricks :-)

 From my point of view, a plugin model as you describe it would be 
indeed a good solution. The DNA/RNA approach seem to be central in the 
on-going efforts towards Blender 2.5. Do you (or maybe Ton, if you're 
reading :-) ) know if a plugin architecture is being discussed for this 
next release?

I'll definitely have a look to that. Thank you.
