Some random questions

[Darius34]

Here are a few random questions I always wondered about, but never placed into any particular topic.


1) Suppose a unit gets damage under the Unit Takes Damage event, and as soon as that happens, a subsequent action heals the unit by GetEventDamage() via life manipulation. Will this reduce lethal (killing) damage? And are there any disadvantages to this method?

2) Is it possible to check the level of a buff on a unit? There is a bj function called UnitHasBuffBJ; it is supposed to check if a unit has a buff, but what it really does is:

function UnitHasBuffBJ takes unit whichUnit, integer buffcode returns boolean
    return (GetUnitAbilityLevel(whichUnit, buffcode) > 0)
endfunction

Therefore is is possible to get the exact level? I want to use it for stacking purposes.

3) Is it possible to check the type of damage received from a damage taken event? Such as ATTACK_TYPE_NORMAL, etc. What does the native ConvertDamageType do?

4) How do I use UNIT_TYPE_MELEE_ATTACKER to check for melee/ranged attackers?

5) UnitCountBuffsEx() counts buffs on a unit, is there a way to get and remove a random buff from a unit?


I know attempting to solve these myself would be possible, but my computer crashed and I don't have Warcraft available now, so I can't do anything. Just wanted to know if you guys knew anything, yeah.

1 : If the unit get healed while the unit dies, the unit dies. If the unit get healed before the unit dies (practice it and its imposible), the unit stills alive. If the unit get healed after the unit dies, the unit simply dies. It should simply heal the unit

2 : A buff is an ability. So a JASS GetUnitAbilityLevel should work.
Wrote quite fast and forget 0 or 1 level.

3 : No.

4 : Not possible unless you register each unit.

5 : Check for each buff, set them in an array variable, and remove one buff randomly via UnitRemoveBuffBJ (or UnitRemoveAbility).

Lol, I didn't get the bottom line there... ...Does it heal lethal damage? And if no, how could I? (I wanted it in a shield-type spell)

3 : No.

So if I want an ability to only reduce/manipulate attack damage, should I combine the damage taken event with a Unit is Attacked event? If not how do I approach this?

4 : Not possible unless you register each unit.

Could you elaborate?

2 : A buff is an ability. So a JASS GetUnitAbilityLevel should work.

5 : Check for each buff, set them in an array variable, and remove one buff randomly via UnitRemoveBuffBJ (or UnitRemoveAbility).

Thanks.

> Will this reduce lethal (killing) damage?
From what I know takes damage event triggers right before the unit takes damage...meaning that you heal him before he takes it thus making him survive a lethal blow this way.

> Is it possible to check the level of a buff on a unit?
Nope, technically buffs aren't leveled - they can either be level 1 (unit has a buff) or 0 (doesn't have). You need to create a new buff for every level you want to check.

> What does the native ConvertDamageType do?
Its used for initializing. Every damagetype is actually an integer, ConvertDamageType is used to define which integer that is in common.j.

> I wanted it in a shield-type spell
There is one in the Spell Index, you might wanna check it out.

1.
Lethal damage is still lethal. But, to die, it would have to be enough damage for an instant kill. As in, more damage than the unit has health, in one hit.

Though it would seem you're going to need to test this


2.
Buffs don't have levels.
It's either 0, the buff isn't there, or 1, the buff is there.

Hmm, all the lethal damage stuff contradicts. I remember looking at the shield spell in the index; at that point there was a 'Does not reduce lethal damage' bug listed. I see it's gone now, but I can't try it; I still don't have WC on my computer. I'll definitely test the shield spell and my own shield when I get the chance.

Anyway, thanks guys. I still have two unanswered questions though, would appreciate it if you could solve them.

4.
IsUnitType(GetTriggerUnit(), UNIT_TYPE_<whatever>) == true / false

Though I've never used it for anything other than "Hero" and "Structure"...

Teh UNIT_TYPE list :

UNIT_TYPE_ANCIENT=ConvertUnitType(19)
UNIT_TYPE_ATTACKS_FLYING=ConvertUnitType(5)
UNIT_TYPE_ATTACKS_GROUND=ConvertUnitType(6)
UNIT_TYPE_DEAD=ConvertUnitType(1)
UNIT_TYPE_ETHEREAL=ConvertUnitType(25)
UNIT_TYPE_FLYING=ConvertUnitType(3)
UNIT_TYPE_GIANT=ConvertUnitType(9)
UNIT_TYPE_GROUND=ConvertUnitType(4)
UNIT_TYPE_HERO=ConvertUnitType(0)
UNIT_TYPE_MAGIC_IMMUNE=ConvertUnitType(26)
UNIT_TYPE_MECHANICAL=ConvertUnitType(15)
UNIT_TYPE_MELEE_ATTACKER=ConvertUnitType(7)
UNIT_TYPE_PEON=ConvertUnitType(16)
UNIT_TYPE_PLAGUED=ConvertUnitType(12)
UNIT_TYPE_POISONED=ConvertUnitType(21)
UNIT_TYPE_POLYMORPHED=ConvertUnitType(22)
UNIT_TYPE_RANGED_ATTACKER=ConvertUnitType(8)
UNIT_TYPE_RESISTANT=ConvertUnitType(24)
UNIT_TYPE_SAPPER=ConvertUnitType(17)
UNIT_TYPE_SLEEPING=ConvertUnitType(23)
UNIT_TYPE_SNARED=ConvertUnitType(13)
UNIT_TYPE_STRUCTURE=ConvertUnitType(2)
UNIT_TYPE_STUNNED=ConvertUnitType(11)
UNIT_TYPE_SUMMONED=ConvertUnitType(10)
UNIT_TYPE_TAUREN=ConvertUnitType(20)
UNIT_TYPE_TOWNHALL=ConvertUnitType(18)
UNIT_TYPE_UNDEAD=ConvertUnitType(14)

Writing :

IsUnitType(GetTriggerUnit(), ConvertUnitType(<whatever>)) == true / false

is a bit faster.

It's either 0, the buff isn't there, or 1, the buff is there.

Btw I tryed using hero abilities level 3 and it returned level 3 for buffs.

Should be in that form :

|cf...<buffId,name>|r

Level : <buffId,level%d>

<buffId,tooltip>

Okay guys, been a long while since, and I almost forgot this thread. So far the only unanswered one is:

3) Is it possible to check the type of damage received from a damage taken event? Such as ATTACK_TYPE_NORMAL, etc.

I was thinking of a way to do this. Say I only want damage from a Unit Attacked event. I'd have a Unit is Attacked event, then inside the event I add Triggering Unit takes damage to another trigger.

However, any damage the triggering unit takes subsequently will be caught by the second trigger's event, so how should I approach this?

Another one is the lethal damage from the shield. I'll test it out and tell you guys the results. Thanks.

EDIT: Tested it, and I'm still unsure if the shield does absorb lethal damage. I cast a 600 damage spell on a unit with 100+ hp left, and a full shield (100 hp also), and it instantly died.

However, the other possibility for this is that the shield does not prevent damage 'spill'. So far, inconclusive.

 

[Darius34]

Bump. Come on guys, still need help.

Could you post the triggers here?
