[C++] Grizzly Hills quest 'Mr.Floppy's Perilous Adventure' question.

[newtech]

Hey there fellows

Alright, so I'm working on learning C++ (expanding from Lua, to C++, mainly cause I'm working for CoA, a Trinity core server), and I've learned the basics of Gossip, however... Now, I'm going to try and make an escort quest, and the actual making of the quest is no problem, its more the scripting of the path, and what to happen on the quest.
So I found that there was already a script in the source code for the quest Mr. Floppy's Perilous Adventure
So, here's the part of the code from the 'grizzly_hills.cpp' script, that I assume is needed to tell me how everything works:

/*######

    NPC_RAVENOUS_WORG           = 26590,   //RWORG
    NPC_EMILY                   = 26588,

    QUEST_PERILOUS_ADVENTURE    = 12027,

    SPELL_MRFLOPPY              = 47184,    //vehicle aura

    SAY_WORGHAGGRO1             = -1800001, //Um... I think one of those wolves is back...
    SAY_WORGHAGGRO2             = -1800002, //He's going for Mr. Floppy!
    SAY_WORGRAGGRO3             = -1800003, //Oh, no! Look, it's another wolf, and it's a biiiiiig one!

    SAY_VICTORY2                = -1800007, //Don't go toward the light, Mr. Floppy!
    SAY_VICTORY3                = -1800008, //Mr. Floppy, you're ok! Thank you so much for saving Mr. Floppy!
    SAY_VICTORY4                = -1800009, //I think I see the camp! We're almost home, Mr. Floppy! Let's go!

Well, basically I just don't understand where in that script, that it tells where to walk and stuff? Like, in Lua it'd be something like... "On time'd event, walk to X, Y and Z coords, spawn evil stuff, wait till evil stuff is dead, continue, etc." Only thing is, I see nowhere in the script where it says anything like 'Go to...' in that C++ script. Now, I've been told that Trinity C++ scripting also has a lot to do with the DB, so maybe it is something in there? Well, I've tried following the most obvious connections from the script into the DB, but I couldn't find anything :S So... Could anyone enlighten me please? :>

Thanks

Note: I take no credit WHATSOEVER for the quest script I provided above. That was an extract from the Trinity source. I merely use it as an example so I can see how it can be done, and so I can expand my knowledge about C++ scripting

[SpellEffects]

Mrfloppy->GetMotionMaster()->MovePoint(0, me->GetPositionX(), me->GetPositionY(), me->GetPositionZ());

Replace me->GetPositionX(), me->GetPositionY(), me->GetPositionZ() with X, Y and Z values of where you want Mrfloppy to go.

Oi! Thanks! =D Ill see if it works now :>
