1. Introduction

EnemySpellDetector makes it easy to detect when the enemy does something 
you want your addon to respond to. It is the purpose of this addon to be 
language independent, however, currently only English is supported, as 
this is a test release.

2. Howto

To use EnemySpellDetector, simply create a function that should be called 
whenever the enemy does something, and register it with EnemySpellDetector.


To register your function, call :
EnemySpellDetector_AddListener(eventType, functionName)

eventTypes:

EnemySpellDetector_Type_Cast - normal spell being cast
EnemySpellDetector_Type_Gain - target / performer gains action
EnemySpellDetector_Type_Perform - performer performs action (against target)
EnemySpellDetector_Type_BeginCast - performer begins to cast action
EnemySpellDetector_Type_BeginPerform - performer begins to perform action


If you wish to register your function with several event types, you will need 
to call EnemySpellDetector_AddListener several times or you can use a table 
in place of eventType.


Your function should look like the following (except for name) :

function EnemySpellDetector_ListenerCallback(performer, action, target, ...)

Parameter description:

performer - who performed the action (if available, otherwise null)
action - what was performed (should never be null)
target - who was the target of the action (if available, may be null)

Note that there are other functions (EnemySpellDetector_RemoveListener for 
example) but most of those are actually quite unnecessary for you to use.
EnemySpellDetector is made to be easy to use and (relatively) lightweight,
both in deployment and when using/coding for it.


3. Known limitations


Your function CAN NOT be declared local. 
You can try using a function pointer instead of a function name. The code 
for this is experimental at best, though.
It is not possible to identify a non player character uniquely from the 
chat messages.
