A concept is high level state that the code is trying to convey, such as say hello(TLK_HELLO), answer some question(TLK_ANSWER), or call for help(TLK_HELP_ME), etc.
You can command a NPC to speak based on a concept by using Speak( AIConcept_t concept, const char *modifiers /*= NULL*/ ) method. This is defined in AI_Speech.cpp.
bool CAI_Expresser::Speak( AIConcept_t concept, const char *modifiers /*= NULL*/ )
{
AI_Response *result = SpeakFindResponse( concept, modifiers );
if ( !result )
{
return false;
}
SpeechMsg( GetOuter(), "%s (%x) spoke %s (%f)\n", STRING(GetOuter()->GetEntityName()), GetOuter(), concept, gpGlobals->curtime );
bool spoke = SpeakDispatchResponse( concept, result );
return spoke;
}
It tries to find a response for the concept from Response System scripts. Then if it finds one, tries to dispatch it.
NPC_talker.cpp is a good example integrating concept speaks within tasks and schedules. If you want to make a custom NPC that talks, this would be the best place to start.
You can also make a NPC choose a response via "DispatchResponse" entity input.
