My question was unclear...
Of course the A* algorythme will be only implement in C++...
The problem is :
1) we have (will have) 100 functions available for the scripts (ex:
2) we have 10 or 20 incoming type of message (ex: on_hitBy(who),
Some NPC must be able to be pre-programmed to execute a succesion of
commands : that's the problem, I have no idea of doing a such thing and I
don't know of to avoid TONS and TONS of "if then else"... I think (but I'm
perhaps wrong), that having some simple knowledge in AI would help, but I
can't find any thing on the web to help me (I've red many many articles but
Any idea or am I always unclear ?

AI is fun. The best AI model I've seen was implemented in Java for a
roguelike game... The
object-oriented nature rocked.
For an AI, write the unmutable stuff (like pathfinding, logic, etc.) in
your C/C++ code. Then write
the control in script.
Something like (in PSEUDO code)
if (see_enemy) then
if (is_dying) then
That's a damn poor example, but I'm tired, so I have an excuse. ;-)
I think for controlling actions (like go north 3, west 4, get item, east 6,
say "My, it is raining
frogs.", attack duck, south 3, west 2, say "Oh no! I lost my magic Blunt
Stick of Sharpness!!!") a
specialized language would do best... something simple like
MOVE east 3
SAY "I'm lost"
