[JASS] Questions

[Kaedus]

1) What would "GetFilterUnit" be in GUI? It's used with Unit Group - Pick every unit in range matching condition.
2) How do I tell if the "EVENT_PLAYER_UNIT_SPELL_CAST" refers to "Unit begins casting a spell" or "Unit finishes casting a spell"?
3) Kind of trigger in general questions: What's the difference between spell cast and spell effect?

1. "Matching Unit"
2. EVENT_PLAYER_UNIT_SPELL_CAST = Begins
   EVENT_PLAYER_UNIT_SPELL_EFFECT = Starts the Effect
   EVENT_PLAYER_UNIT_SPELL_ENDCAST = Stops
   EVENT_PLAYER_UNIT_SPELL_CHANNEL = Begins channeling
   EVENT_PLAYER_UNIT_SPELL_FINISH = Finishes
   
   You'll want to use EFFECT, it's the most accurate. (After mana cost, in range, cooldown, backswing, but retains all the event responses)
3. Spell cast: before mana cost, cooldown, backswing, etc
   Spell effect: after the above
   
   Basically like "A Unit Is Attacked" versus an attack-detection system using "XXX Unit is Damaged"

Thanks man. Good help .

So why is it when you use EVENT_PLAYER_UNIT_SPELL_FINISH, GetSpellTargetUnit () returns null?

The spell is finished. It's all over, there is no target anymore.
