[Bf-committers] Node system for game logic

[Dalai Felinto]

Hi Sjoerd,

two quick questions:
1) any plans to license it in a non-viral license (e.g. BSD)?

2) how well does it do in terms of performance? If I remember correctly one
of the good points of Benoit's proposal was the overall structure of C++
code wrapped around Python but without necessarily running much Python
code(at least to reduce the overhead of dealing with python types for any
manipulation).

3) does it work for programmers as well?
This layer of abstraction is also what permit programmers to access through
a programming API (i.e. Python, but it would be lovely to see Lua supported
as well) the same functionality that is available graphically .


Thanks for sharing your project, it seems quite interesting (I need to look
at it properly later though ;).

> but it works.
> This makes it possible for non-programmers to create and modify game logic.
> I have made a screencast that demonstrates this for a simple 3D scene:

> The main limitation is that there are no bindings yet to the BGE, only to
> Panda3D.
> It still needs to be ported to Python3.2, and I am not very familiar with
> the BGE source code.
> Also, a lot of important nodes (sound, physics, mouse picking, networking)
> are still missing.

> I am looking forward to join forces with Benoit and Sven, and with anyone
> else who is interested.
> Any feedback is welcome!
