[Bf-python] A question about the current and future capabilities Python scripting in Blender

[Goat Man]

Hi Karl, i'd also like to see this happen.  Custom logic bricks, or python
defined logic nodes as Campbell mentioned.

In the thread you linked, Carsten says he sees no use for realtime update or
dynamically adding logic bricks while the BGE is running.  But i like the
idea, the best visual programming interface i have come across is Scratch.
 Its a big deal to be able to see the update while you edit the blocks.  As
it is now with BGE, blender is either in "creator mode" or "BGE" mode, but
it can't do both at the same time, right?  Note that Scratch uses snapping
logic bricks, not nodes excatly - Ideasman, i like snapping bricks like
squeak better than free floating nodes, its more compact and clear, too many
nodes and its going to be hard to see the logic.
