I WILL NOT be explaining what the code is, i will explain some parts of the code though!
Also I would like to apologize in advance for the messiness of teh code, the post is not wide enough
YOU MUST FIRST HAVE THE SOURCE CODE FOR ANTRIX, AND SOMETHING LIKE VISUAL STUDIO 2005 or 2003 otherwise you can't do this, I use Visual Studio so it will be based on that
Inside Visual Studio create a new C++ source file by going to file->new->file->c++ file->click open
save the file as NewScript inside the InstanceScripts Folder, and copy and paste this code
or
First make a text file in the InstanceScripts folder name it NewScript.cpp make sure it doesnt say NewScript.cpp.txt now open the file with notepad or whatever word processing tool you have and copy and paste this code

#include "StdAfx.h" //these are required otherwise it wont compile and just give you hundreads of errors
#include "Setup.h"
#define MOBNAME XXXXXX //You can change MOBNAME to Whatever you want, Make sure to keep it all capitals, the XXXXX can be changed to the mobs ID Number in the DB
#define SPELL1 XXXXXX //Samething here almost, change SPELL1 to Whatever you want, just keep it all capital and change the XXXXX to a spell number
#define SPELL2 XXXXXX //repeat for how many spells you want, for this tutorial im gonna keep it with 2
#define SPELLSOUND XXXXX //this is for when they cast a spell they say something you can get all the sound ids in the soundentries.dbc you can turn it into a .csv with a convertor
class MOBNAMEAI : public CreatureAIScript
{
public:
ADD_CREATURE_FACTRY_FUCNTION(MOBNAMEAI); // Make sure to change MOBNAMEAI to The Name next to class
SP_AI_Spell spells[2]; //where it says spells[2] you can change the 2 to however many spells you have
bool m_spellcheck[2]; //same thing as above you can change the 2 to however many spells you have
MOBNAMEAI(Creture *pCreature) : CreatureAIScript(pCreature)
{
nrspells = 2; //same as before change to 2 to however many spells you have
for(int i=0;i<nrspells;i++)
  {
   m_spellcheck[i] = false;
  }
spells[0].info = sSpellStore.LookupEntry(SPELL1); //change SPELL1 to the define you made it as
spells[0].targettype = TARGET_VARIOUS; //I will put all the targettypes at the end
spells[0].instant = true; //wether it is instant or not
spells[0].perctrigger = 16.0f; //how often the spell is cast
spells[0].attackstoptimer = 1000; //can't remember how this is handled
spells[0].soundid = SPELLSOUND; // you can either put a number here or just use your define
spells[0].speech = "You can make them say things when they cast spells by having text here!"; //text that the mob yells when they cast the spell
spells[1].info = sSpellStore.LookupEntry(SPELL2); //change SPELL2 to the name of your spell 2 thing
spells[1].targettype = TARGET_ATTACKING;
spells[1].instant = true;
spells[1].perctrigger = 9.0f;
spells[1].attackstoptimer = 2000;
spells[1].soundid = SPELLSOUND;
spells[1].speech = "You can make them say other things for different spells";
}
void OnCombatStart(Unit* mTarget)
{
_unit->SendChatMessage(CHAT_MSG_MONSTER_YELL, LANG_UNIVERSAL, "Have some text here for when you aggro him he yells it");
_unit->PlaySoundToSet(XXXXXX); //change the XXXXXX to whatever number that is in the soundentries.dbc file
RegisterAIUpdateEvent(_unit->GetUInt32Value(UNIT_FIELD_BASEATTACKTIME));
}
void OnTargetDied(Unit* mTarget)
 {
if (_unit->GetHealthPct() > 0) // Hack to prevent double yelling (OnDied and OnTargetDied when creature is dying)
  {
int RandomSpeach;
sRand.randInt(1000);
RandomSpeach=rand()%2;
switch (RandomSpeach)
{
case 0: 
_unit->SendChatMessage(CHAT_MSG_MONSTER_YELL, LANG_UNIVERSAL, "Have some text here for when he kills a player");
_unit->PlaySoundToSet(XXXXX); //change the XXXXXX to whatever number that is in the soundentries.dbc file
break;
case 1:
_unit->SendChatMessage(CHAT_MSG_MONSTER_YELL, LANG_UNIVERSAL, "if there are two sounds then put some text here");          
 _unit->PlaySoundToSet(XXXXX); //change the XXXXXX to whatever number that is in the soundentries.dbc file
break;
}
}
}
void OnCombatStop(Unit *mTarget)
 {
  _unit->GetAIInterface()->setCurrentAgent(AGENT_NULL);
  _unit->GetAIInterface()->SetAIState(STATE_IDLE);
  RemoveAIUpdateEvent();
 } //dont change any of this unless you know what your doing
void OnDied(Unit * mKiller)
 {
_unit->SendChatMessage(CHAT_MSG_MONSTER_YELL, LANG_UNIVERSAL, "Have some text here for when he dies");
_unit->PlaySoundToSet(XXXXX); //change the XXXXXX to whatever number that is in the soundentries.dbc file
 
RemoveAIUpdateEvent();
 }
void AIUpdate()
 {
Timer = Timer + 1;
if (Timer == 200) //you cn change the number to whatever you want after the timer reaches that number it will cast the spell below it
{
 _unit->CastSpell(_unit, spells[0].info, spells[0].instant); //you can change the numbers to whatever spell you want
}
else
{
float val = sRand.rand(100.0f);
SpellCast(val);
}
} //leave the rest of it alone unless you know what your doing
void SpellCast(float val)
 {
if(_unit->GetCurrentSpell() == NULL && _unit->GetAIInterface()->GetNextTarget())
{
float comulativeperc = 0;
Unit *target = NULL;
for(int i=0;i<nrspells;i++)
{
if(!spells[i].perctrigger) continue;
 
if(m_spellcheck[i])
{
target = _unit->GetAIInterface()->GetNextTarget();
switch(spells[i].targettype)
{
case TARGET_SELF:
case TARGET_VARIOUS:
_unit->CastSpell(_unit, spells[i].info, spells[i].instant); 
break;
case TARGET_ATTACKING:
_unit->CastSpell(target, spells[i].info, spells[i].instant); 
break;
case TARGET_DESTINATION:
_unit->CastSpellAoF(target->GetPositionX(),target->GetPositionY(),target->GetPositionZ(), spells[i].info, spells[i].instant); 
break;
}
if (spells[i].speech != "")
{
_unit->SendChatMessage(CHAT_MSG_MONSTER_YELL, LANG_UNIVERSAL, spells[i].speech.c_str());
_unit->PlaySoundToSet(spells[i].soundid); 
}
m_spellcheck[i] = false;
return;
}
if(val > comulativeperc && val <= (comulativeperc + spells[i].perctrigger))
{
_unit->setAttackTimer(spells[i].attackstoptimer, false);
m_spellcheck[i] = true;
}
comulativeperc += spells[i].perctrigger;
}
}
}
protected:
 int nrspells;
 int Timer;
}; //DO NOT TOUCH ANYTHING HERE UNLESS YOU KNOW WHAT YOUR DOING!
void SetupMOBNAME(ScriptMgr * mgr)
{
 mgr->register_creature_script(MOBNAME, &MOBNAMEAI::Create); //change MOBNAME to the define you used, also change MOBNAMEAI to the one you used at the beginning
}

Now we aren't done yet we need to go into Setup.cpp and Setup.h
In Setup.cpp

//Where it says SetupTheMechanar(mgr); put SetupMOBNAME(mgr);
//Where MOBNAME = the define you used in the script so it wuld look like this
SetupTheMechanar(mgr);
SetupMOBNAME(mgr);
//Simple as that

Now for Setup.h

/*Find void SetupTheMechanar(ScriptMgr * mgr); and put void SetupMOBNAME(ScriptMgr * mgr); under it where MOBNAME = teh define you used in the script so it would look like this*/
void SetupTheMechanar(ScriptMgr * mgr);
void SetupMOBNAME(ScriptMgr * mgr);

Now we need to add our file to the project Inside visual studio open up the InstanceScripts2005.vcproj or InstanceScripts2003.vcproj
then click the + next to the project and right click the folder called scripts and put your cursor over to add and click existing item, navigate to the InstanceScripts folder, double click on NewScript.cpp and badda bing your done with that
Now just compile and replace the InstanceScripts.dll in your script_bin folder for your server with the one in teh bin, script_bin folder!
Here are all the targettypes

TARGET_SELF,
TARGET_VARIOUS,
TARGET_ATTACKING,
TARGET_DESTINATION,
TARGET_SOURCE,

This post makes me wish I were smarter =(. I'd love to get into this stuff someday.

[halolouie]

very nice well explained +rep

[destroyah]

excuse me but where can i find the antrix source?

[Arthas117]

now I wish i was a smartass programmer of antrix..don't understand a shit

[Tazjin]

Well, I already knew that but its VERY great for beginners.
