Two simple questions

I'm a seven-year veteran game programmer, but a total newb to TGE, so when I say that I'm having a little trouble with TGE, please understand that it's only because I don't completely understand this interface.

Some people have asked me to teach them how to add audio to a TGE game, and how to add multiple AI objects. I've read through several tutorials now (some really great ones), but none of them seem to talk about placing AI objects, or attaching event triggers (for audio).


I've found the following code in player.cs:

datablock AudioProfile(DeathCrySound)
{
fileName = "~/data/sound/orc_death.ogg";
description = AudioClose3d;
preload = true;
};

function Player::playDeathCry( %this )
{
%this.playAudio(0,DeathCrySound);
}

This seems fairly straightforward, and I can call up the sound from the console by saying "player_id.playDeathCry();". However, when I change something in the player.cs (i.e. get it to play a sound on armor collision or something), I don't see those changes in-game. If I shut down the engine, then restart it, I still don't see those changes (BTW, I also tried echoing info to the console on collision. Still, no dice).

Also, I can't seem to find where (I'm looking at the example FPS game now) the AI orc is created, or how to create more of them. In the creater menu, I don't see that actor listed, and I can't grep "orc" anywhere in the sample. Where is this actor added, and can I create more of them in the editor?

If you guys know of a tutorial I missed, I would greatly appreciate some help.

Thanks for your time.
