Re: [GD-General] Scripting Systems

[<e_a...@ya...>]

Hi, 

I'm quite surprised nobody pronouce the name of python
yet.

So here I go :
I found Python to be a good scripting language. From
what I've been told, the language is cleaner than Lua
(I've never used Lua ). There are a lot of
tools/site/support anywhere on the web.
It supports coroutine, have a lot of useful lib (Zip
for instance ). It can be used for other tasks
(automated build, HTTP stuff, ... ).
Last but not least, the HAP debugger is a remote
debugger/IDE.

There can be some perf issue on this gen consoles,
thought I think some people manage to port it and use
it (there are some GC and PS2 Python project on the
web), and with the new console gen that is to come,
there will be no reason not to use it...


Hope it helps 

Emmanuel
