[Snippet] Damage Calculator

=====DamageCalculator v1.1
=====By Mckill2009

I don't know if this site has this snippet already but I'm posting it anyway
to get feedbacks, basically this is a small code that can get the random
damage from a certain unit based on what is written in the object editor.

Take note that the damage return DOES NOT mean the EXACT damage given by
the unit, therefore this does not affect the armour of the attacked unit.

The returned damage computation are based on; (see object editor)
    Primary Attribute (for hero only)
    Damage Base
    Damage Number Of Dice
    Damage Sides Per Die

API:
    static method getHeroDC takes integer mainattribute, real damBase, real damDice, real damDie returns real
        - local real dam = DamageCalculator.getHeroDC(1,2,3,4)    
        - mainattribute (the PRIMARY ATTRIBUTE of the hero)
        - damBase (the DAMAGE BASE)
        - damDice (the DAMAGE NUMBER OF DICE)
        - damDie (the DAMAGE SIDES PER DIE)

    static method getUnitDC takes real damBase, real damDice, real damDie returns real
        - local real dam = DamageCalculator.getUnitDC(1,2,3)
        - damBase (the DAMAGE BASE)
        - damDice (the DAMAGE NUMBER OF DICE)
        - damDie (the DAMAGE SIDES PER DIE)

library DamageCalculator

struct DamageCalculator extends array

    static method getHeroDC takes integer mainattribute, real damBase, real damDice, real damDie returns real
        return GetRandomReal((mainattribute+damDice)+damBase, (mainattribute+(damDice*damDie))+damBase)
    endmethod
    
    static method getUnitDC takes real damBase, real damDice, real damDie returns real
        return GetRandomReal(damBase+damDice, damBase+(damDice*damDie))
    endmethod    

endstruct

endlibrary

How it works?

• DC Hero
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • (Unit-type of (Attacking unit)) Equal to Blood Mage
  • Actions
    • Custom script: local real dam = DamageCalculator.getHeroDC(GetHeroInt(GetAttacker(),false), 0, 2, 4)
    • Custom script: call BJDebugMsg(R2S(dam))

• DC Unit
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • (Unit-type of (Attacking unit)) Equal to Knight
  • Actions
    • Custom script: local real dam = DamageCalculator.getUnitDC(25, 2, 5)
    • Custom script: call BJDebugMsg(R2S(dam))

Changelogs

v1.1
- Integer returned replaced by reals
- Code reduced

 

[Magtheridon96]

CD is not a very appropriate struct name.

 

[mckill2009]

I understand, even CustomDamage is not, but I cant think of anything else that's why I made CuscomDamage to struct name CD ...

 

[Bribe]

"DamageCalculator".

Also, inline those locals, you don't work for Blissard.

 

[Magtheridon96]

And that's a good thing, because I heard Blizzard's coders get minimum wage :3

Updated:
name changed & shorten code

library DamageCalculator /* Requires nothing because mckill2009 is so awesome. */

    struct DamageCalculator extends array
        static method getHero takes integer mainattribute, integer damBase, integer damDice, integer damDie returns integer
            return GetRandomInt(mainattribute + damDice + damBase, damDice * damDie + damBase + mainattribute)
        endmethod
        
        static method getUnit takes integer damBase, integer damDice, integer damDie returns integer

[Bribe]

Damage is also real values, so it should be GetRandomReal on both those.

 

[KnnO]

Damage is also real values, so it should be GetRandomReal on both those.

if so, you should use real values even in the GUI demo

 

[mckill2009]

Thanks Mags...

if it's in real, whats the difference of taking 32.3 and 32.2 damage?, that's why I made it a
whole number...

 

[Bribe]

Because damage is a real number, not an integer. Better to simply use reals which is what people expect damage to be in.

 

[KnnO]

Because the damage in warcraft is a real number, but the unit's health is integer (I tink).
also you could use it for these functions:

UnitDamagePoint(whichUnit,delay,radius,x,y,amount,attack,ranged,attackType,damageType,weaponType)
UnitDamageTarget(whichUnit,target,amount,attack,ranged,attackType,damageType,weaponType)

without having to convert it to integer

edit: like what bribe said

 

[Magtheridon96]

Actually, unit health is also a real, and that's why GetWidgetLife returns a real.

Try placing a unit with 50% HP on the map (having regeneration) and display his current HP every 0.05 seconds.

 

[mckill2009]

I know that all is real but the point of this is to return a whole number, meaning,
no decimals, so that the damage is full, so instead of 3.2, it is 3 or 4...
anyway, Ima change it tonight if that's more accurate...

 

[Bribe]

I think "3.2" is more full than "3" if the situation permits it. Keep in mind that the damage will then be reduced by damage type/enemy armor type and enemy armor value and possibly increased thanks to a critical strike or something. So that .2 decimal value might amount to something a bit more significant.

 

[mckill2009]

Ok I've changed it...Bribe pls change the title to DamageCalculator, thanks...

 

[Magtheridon96]

Well, this is functional, and it has it's uses.

I'll go ahead and approve it.

 

[gorillabull]

its accurate for heroes and extremely inaccurate for units but i like how it gets the raw damage before it is reduced by anything that is 1 feature damage systems dont have

 

[Magtheridon96]

It only does that because it's simple math ._.

 

[mckill2009]

extremely inaccurate for units

pls explain...

 

[gorillabull]

never mind i did it wrong sorry works great for me
