1. Ok, well there is an event under Specific Unit Events thats is Unit Takes Damage. We need to use this because without it, you cannot figure out how much damage the hero does. However, you normally can't do this because it requires a Specific Unit(which can only be done by adding events to this Trigger from another Trigger, or selecting pre-placed units on your map.) So, you need to make another trigger that goes like this:
Code:
Unit Enters Map
Events:
Unit - A unit enters(Playable map area)
Conditions:
None
Actions:
Trigger - Add to Unit Damaged<gen> the event (Unit-(Entering Unit) Takes damage)
What this does, is every time a unit is created, it will add the event that the new unit takes damage to your spell trigger. It might not make too much sense now, but after you read the other 2 triggers you need then hopefully you'll understand ^^. Heres the second one, which detects when the unit takes damage from the hero. I'll name the spell being cast Spell and the buff that the spell gives the hero SpellBuff.
Code:
Unit Damaged
Events:
None(but they will be added once in game through the first trigger)
Conditions:
((Damage Source) has buff (SpellBuff) Equal to True (this is a boolean condition btw)
Actions:
Do whatever you want the spell to do here. For example, if you want the hero to deal 2 times damage, use
Unit - Order (Damage Source) to damage (Triggering unit) for (Damage taken) using attack type Spells and damage type Normal.
Damage Source will be your hero, and Triggering Unit is used to get the unit damaged(so your target). Since the hero already attacked them once,
we add the damage he just did on that attack again, therefore doubling it.
Ok, last trigger. This is used to tell when the hero actually casts the spell.
Code:
Hero Casts Spell
Event:
Unit - A unit Starts the effect of an ability.
Condition:
(Ability being cast) Equal to (Spell)
Action:
Here you need to have a dummy unit cast a buff on the hero,
and order your hero to attack the target. I will show both here.
Unit - Create 1 (Dummy Unit) for (Owner of (Casting unit)) at position of Casting unit facing Default building facing degrees.
Unit - Add a 1.50 second Generic expiration timer to (Last created unit)
Unit - Add a 1.50 second generic expiration timer to (Last created unit)
Unit - Add (Dummy Buff Spell) to (Last created unit)
Unit - Set Level of (Dummy Buff Spell) for (Last created unit) to 1
Unit - Order (Last created unit) to (order string of the spell your dummy buff spell was based on) (Casting unit)
Unit - Order (Casting unit) to Attack (Target unit of ability being cast)
Ok, I'm not sure how much you know about dummy spells/units but ill just tell you what they are anyways =P. First, you need to make a dummy unit that uses the model none.mdl(making it invisible), has the ability Locust(making it unselectable), and has the ability Invulnerable(making it so it won't be killed before it gets the spell off). Then, you make a dummy spell that adds a buff to the target being cast for about 3 seconds, but has no actual effects. Make sure its mana cost and casting time are 0. Then, you add this spell to the dummy unit and add an expiration timer to the dummy unit so it will be removed from the map when it's finished casting. Then you set the level of the dummy spell to level 1, so it can be casted. Last, you order the dummy unit to cast the dummy spell. For example, if you base a dummy spell on the Inner Fire ability, you would put:
Code:
Unit - Order (Last created unit) to (Human Priest - Inner Fire) (Casting unit)
And finally, you need to order your hero to attack the target unit so that the Unit Damaged trigger will fire. Whew. Sorry if any of that was confusing, it's alot of stuff to put into one explanation ;). On to your other question!
2. This one's not as hard. What you need to do is make a spellbook ability, and make the only spell it can contain be your Defense spell. Put minimum and maximum # of spells to 1, and change the tooltips to what you need. Next, add that spellbook you created to your hero(don't add the Defense spell, it will automatically be put on when he learns the spellbook ability). Now, when your hero learns the Spellbook ability, use the trigger:
Code:
Events:
Hero learns your spellbook ability
Conditions:
None I think
Actions:
Player - Disable (Your Spellbook Ability) for (Owner of (Learning Hero))
This will make it so the unit doesnt have the spellbook ability anymore, so there is no icon for it, but your Defense ability that was inside of the spellbook will stay! This way, there's no icon or anything. If you have any more questions just let me know =P.
