Creating my own shield buff system

08-04-2007, 07:53 PM

Ok, so I want a self-buff shield (blocks X amount of damage) that regains some of its hit points every time a nearby unit dies. I came upon Shadow 1500's shield system here.
http://www.wc3campaigns.net/showthre...ghlight=Shield
In the forum, Vexorian and Anitarf mentioned that it would be easier for the person to code it themselves.

The system seems to just be one trigger and three commands

JASS:

function InitTrig_Load_Game_Cache takes nothing returns nothing
    call FlushGameCache(InitGameCache("localvars.w3v"))
    set udg_hash = InitGameCache("localvars.w3v")
endfunction

Trigger:

Actions

Custom script: call CreateShield(GetTriggerUnit(),100,0,'B000',3,0)

-------- CreateShield takes unit target, real shieldhp, real duration, integer buffId, real regenerate, real armor --------

-------- Target = Triggering Unit --------

-------- Shield Hitpoints = 100 --------

-------- Duration = 0 (Until depleted/dispelled) --------

-------- Buff = B000 (Shield) --------

-------- Regeneration = 3 HP per second. --------

-------- Armor = 0 (reduce 0% dmg taken) --------

Trigger:

Actions

Custom script: call CreateShield(GetTriggerUnit(),100,0,'B000',0,.50)

-------- CreateShield takes unit target, real shieldhp, real duration, integer buffId, real regenerate, real armor --------

-------- Target = Triggering Unit --------

-------- Shield Hitpoints = 100 --------

-------- Duration = 0 (Until depleted/dispelled) --------

-------- Buff = B000 (Shield) --------

-------- Regeneration = 0 --------

-------- Armor = 0.50 (reduce 50% dmg taken) --------

Trigger:

Actions

Set guy = Protector of Men 0000 <gen>

Custom script: call CreateShieldEx(udg_guy,300,-1,0,3,0,"|cFF3232FF",true)

-------- CreateShieldEx takes unit target, real shieldhp, real duration, integer buffId, real regenerate, real armor, string color, boolean dmgspill --------

-------- Target = Guy --------

-------- Shield Hitpoints = 300 --------

-------- Duration = -1 (Indestructable) --------

-------- Buff = None (not using buff cuz shield is indestructable) --------

-------- Regeneration = 3 HP per second --------

-------- Armor = 0 (reduce 0% dmg taken) --------

-------- Color = |cFF3232FF (Blue) --------

-------- Damage Spill = Yes --------

The system offered very little explanation on how to use it. Are these just single line JASS commands? If so, creating my shield buff would be relatively easy provided I could obtain the current shield hit points of a shield (whenever a nearby unit dies, "set current shield hp = current shield hp +10")

Thanks ahead of time.

Or you could do it "The Easy Way"

The Easy Way:

1) Make a ability based of mana shield
2) change mana cost and other stuff to w/e you want just have the mana drained per damage = 0
3) MAke a trigger like so

Trigger:

Event -

Unit Dies

Condition

Event

If Unit in range of dying unit has buff = to Shield

Then

set tempgroup = unit group units in range of dying unit with buff Shield

pick every unit in tempgroup and do actions

set tempreal = hp of picked unit

set picked units hp to tempreal + VALUE

As for damage make another trigger such as

Trigger:

Event

a unit is attacked

conditions

events

if attacked unit has buff Shield then do actions

If ShieldDamageAbsorbed >= Damage to absorb

then

Do Nothing

Else

Remove Buff Shield

depending on you application it might need ot be tweaked but that is the basic stuff

To have it change the shield hp jsut have it subtract 10 grom ShieldDamageAbsorbed every attack instade of setting the units 10 to more

There's a couple of flaws with what I want from that.
1. I don't want the shield to heal the caster, I want it to add hp to the shield. So if the shield is at 50 hp, and a unit dies, it gains 10 hp and the shield is now 60 hp.
2. The damage trigger will only remove the buff if one damage source is greater than the shield, rather than the shield wearing away with each hit.
3. How do I detect how much damage has been taken? I assume I just use a damage system.

2) set add a Set ShieldDamageAbsorbed = Damagetotake
3) a damage system would work for this and for ^
