First 500 primes

Useful for things like items that can only be equipped by certain heroes or fit into certain slots.

id = id1*id2*id3 etc

if it fits
id%targetId = 0

For example

2*3*7=42

42%5 = 2
42%2 = 0
42%3 = 0
42%7 = 0
42%11 = 9

JASS:

    function GetPrimeByIndex takes integer prime returns integer
        return p[prime]

The library should be named something more specific to its function, maybe
change the library name to "First500Primes" and change the function to sth
like "GetPrimeByIndex".

Magtheridon96 · Sep 5, 2011

I agree with Bribe.
GetPrimeByIndex seems better

Man, if only recursion was ok in Jass

Then I'd be able to post this:

JASS:

library Fibonnacci

    function GetFibonnacciByIndex takes integer index returns integer
        if 0==index then
            return 0
        elseif index==1 then
            return 1
        endif
        return GetFibonnacciByIndex(index-1) + GetFibonnacciByIndex(index-2)
    endfunction

endlibrary

lmao

Since I can't find any use for a Fibonnacci Sequence library, I'll just post this instead:

JASS:

library GoldenRatio
    globals
        private constant real GOLDEN_RATIO = (1 + SquareRoot(5))/2
    endglobals

    function GetGoldenRatio takes nothing returns integer
        return GOLDEN_RATIO
    endfunction
endlibrary

I'm already using this in a map of mine to scale the images so that they look "Pleasing"

QSort optimized for integer comparisons (could put in compare and exchange methods to work with any type, but I personally needed integers so if someone wants to quickly mod this to use compare/exchange, go for it).

So the user is also expected to use ridiculously short variable
names that don't make sense. How am I supposed to know what
"v" or "v2" are?

What is this useful for?

You should also cache (f+t)/2 into a local.

Magtheridon96 · Sep 6, 2011

What is this useful for?

Possibly a Multiboard that can sort stuff like a Leaderboard :/

Should be Save.../Load...Unit...Loc/Mana/Life because the argument expects
a location or real variable.

Nestharus · Sep 7, 2011

Changed ; )

Bribe · Sep 8, 2011

SaveUnitPosition/Life/Mana bumped to first post.

If anyone else thinks of some good ideas for save/load snippets, pretty
much everything has a place right now because it's a fresh market.

Magtheridon96 · Sep 8, 2011

Save/Load Hero Strength
Save/Load Hero Agility
Save/Load Hero Intelligence

or, to support custom attributes, you can create a snippet that simply pushes an integer to the NumberStack given a maximum value.

Nestharus · Sep 8, 2011

stack.push is already pretty easy.

And for save/load hero stats, that's much too easy. Well, actually, just thought up a good way to do it but it's dependent upon how the map does stat allocation = ).

See, you'd just save allocated stat points, and the cap would be the total amount of stats points the hero has at a given level ; P.

Nice

Fast write, Fast read, Fast reset -> Awesome data structure (I know it's dynamic and limited, but it's quite useful)

edit
Nes inspired me to write a data structure based library, so I did:

JASS:

library RDS requires Table // Random Data Structure
    
    struct RDS extends array
        private static integer ic = 0
        private static integer ir = 0
        private thistype rn
        private Table data
        private integer index
        method throw takes integer i returns nothing
            set index = index + 1
            set data[index] = i
        endmethod
        method get takes nothing returns integer
            local integer i = GetRandomInt(1,index)
            local integer j = data[i]
            set data[i] = data[index]
            set index=index-1
            return j
        endmethod
        method delete takes integer k returns nothing
            local integer i = 1
            loop
                exitwhen i>index
                if k==data[i] then
                    set data[i] = data[index]
                    set index=index-1
                    return
                endif
                set i=i+1
            endloop
        endmethod
        static method create takes nothing returns thistype
            local thistype this
            if 0==ir then
                set ic=ic+1
                set this=ic
            else
                set this=ir
                set ir=.rn
            endif
            set .index = 0
            set .data = Table.create()
            return this
        endmethod
        method destroy takes nothing returns nothing
            call .data.destroy()
            set .rn=ir
            set ir=this
        endmethod
    endstruct
    
endlibrary

This is useful for a "Random Hero" system in an AoS map >

JASS:

struct Example
    globals
        private RDS Q
    endglobals

    static method run takes nothing returns boolean
        call CreateUnit(GetTriggerPlayer(),Q.get(),0,0,0)
    endmethod

    static method onInit takes nothing returns nothing
        local trigger t = CreateTrigger()
        set Q = RDS.create()
        call Q.throw('H000')
        call Q.throw('H001')
        call Q.throw('H002')
        call Q.throw('H003')
        call Q.throw('H004')
        call Q.throw('H005')
        call TriggerRegisterPlayerChatEvent(t,Player(0),"-random",true)
        call TriggerAddCondition(t,Condition(function thistype.run))
        set t = null
    endmethod

endstruct

baassee · Sep 8, 2011

Last example was quite nice I have to say. Especially with the option of the delete method. Very useful for random picking although it should be created in a tutorial for GUIers/NotComplexEnoughJassers as they probably will never look here nor have a clue about the thingie.

Magtheridon96 · Sep 8, 2011

That's actually why the "Small Code Snippets" thread was moved to the "Triggers and Scripts" section =P

baassee · Sep 8, 2011

Still don't think it got better.

Magtheridon96 · Sep 8, 2011

Me neither >

Bribe · Sep 9, 2011

Maybe I should move it to World Editor Help Zone?

You guys can decide.

@Mag, you should see the random data structure I built that uses
Table. Yours is static so you can't create/destroy random data lists
of large capacity, change the weight of various items, etc.

I really need to release that stuff! I don't know why I keep forgetting.

Magtheridon96 · Sep 9, 2011

You're probably right :/

baassee · Sep 9, 2011

The thing is that it's JASS and most people are afraid of it not knowing the fact that the whole game is built upon it (and JASS built upon C but that's a bit too much for people not even knowing WC3 GUI). That's how I think it is but I find this thread very amusing and creative (in a learning perspektive).

Bribe said:

LOL I should make a reminder app in VB (haha my school don't support JAVA/Ruby/C++/Python) that will remind you in an annoying way.

Magtheridon96 · Sep 9, 2011

Jass isn't built upon C++, it's a seperate language interpretted by the "Jass interpreter" written in C++

(That's why variable names have an influence on performance. (fail) xD

baassee · Sep 9, 2011

Yeah yeah meant that. You sure it's not C?

Magtheridon96 · Sep 9, 2011

I'm quite sure

baassee · Sep 9, 2011

Alrighty then. Gosh all these languages confuse me...

Troll-Brain · Sep 9, 2011

All you really need is the assembly language (even if technically there are many assembly languages)
You also need to move this topic in all wc3 related forums, so the jass will conquer this forum and then the world.

That won't work >.>. Regeneration is on a timed interval. The only way to record regeneration is to catch it in a second interval.

Magtheridon96 · Sep 9, 2011

Oh sorry Nes, deleted my post

Bannar · Sep 9, 2011

I guess that you guys are mostly right. Most ppl ingore threads that are 'underlined' (at the top of given section) because they think that those thread are for geniuses.
Although you might have a luck with catching up few random guys to learn some new things.
Like me xD. I'm reading this thread from time to time.. and I've learnt a lot. I realy appreciate what you are doing here ;<

Why doesn't IsUnitType(u,UNIT_TYPE_HERO) work?

Nestharus · Sep 11, 2011

There was some bug with it I thought?

Or maybe I was thinking IsUnitHeroId or w/e.

Troll-Brain · Sep 11, 2011

http://www.hiveworkshop.com/forums/1855746-post352.html

So IsUnitType could work like the same way, but it will always work just because it takes an unit argument, and an hero must have its first letter of rawcode an uppercase.

Nestharus · Sep 12, 2011

Useful for when needing to add xp for something like a quest in a map that uses the Hero Reward lib.

JASS:

library GetBonusXP
    //xpRate: desired xp rate, like 350
    //awardLevel: the level of the award, like a level 5 quest
    //awardedLevel: the level of the awarded thing, like a level 10 unit
    //xpRecieveRate: the rate at which xp recieved increases relative to level (bigger means more xp)
    //xpReqRate: the rate at which xp requirement increases relative to level (bigger means more xp required)
    
    //maxes:
    //  xpBountyRate:   1.8
    //  xpReqRate:      2.1
    
    function GetBonusXP takes integer awardLevel, integer awardedLevel, real xpRate, real xpRecieveRate, real xpReqRate returns integer
        local real xp = Pow(awardLevel+1,xpRecieveRate)
        local real xpReq = Pow(awardedLevel,xpReqRate)
        
        //calculate awarded xp

library UnitAlive requires UnitIndexer, UnitEvent

This way, if you want to remove the native UnitAlive from a system (Status for example),
you don't have to touch anything but the native declaration.

baassee · Sep 14, 2011

And the requirements of all the libraries that uses UnitAlive

Bribe · Sep 14, 2011

It's easier to just knot use the UnitAlive native, I'd rather use the optimizer to shorten the variable names and suffer the insignificant speed loss of IsUnitType, because the optimizer gives you way more speed advantage overall.

Magtheridon96 · Sep 15, 2011

Can't the IsUnitType safety be disabled?

Bribe · Sep 15, 2011

Well it is on the list of things you can toggle, is it not able to be disabled for you?

Magtheridon96 · Sep 15, 2011

I just checked.
You can disable it

Actually, you're supposed to enable it

It's initially disabled ^_^

This function will cause desync if units have another different object editor setting other than MODEL.

JASS:

function CreateUnitWithDifferentModel takes player p, integer unitId1, integer unitId2, real x, real y, real facing returns unit
//Desync if there is another different object editor setting other than model :O
    local integer id = unitId1
    if GetLocalPlayer() == p then
        set id = unitId2
    endif
    return CreateUnit(p, id, x, y, facing)
endfunction

Edit:
•This works with icon... until a player sees icon (So you can say it doesn't work

)

•There is something wrong with soundsets but I don't know what is it, It sometimes causes desync and sometimes not.I tested with footman and highelfswordsman soundsets.

•Anything else?

Troll-Brain · Sep 15, 2011

Always thought about it and never tested (mostly because i didn't had the use), good to know that it doesn't desync instantly if used properly, but that makes sense.

Ceday · Sep 15, 2011

I surprised when

JASS:

GetEventDamage

didn't cause desync when I did this.

JASS:

function TEST5ACT takes nothing returns nothing
    local unit u = CreateUnit(Player(0), 'hfoo', 0, 0, 0)
    local real x = 10.00
    if GetLocalPlayer() == Player(0) then
        set x = 20.00
    endif
    call TriggerRegisterUnitEvent(gg_trg_Test_5_Show_Damage, u, EVENT_UNIT_DAMAGED)
    call UnitDamageTarget(u, u, x, true, false, null, null, null)
    
endfunction

It showed 20 to me, and 10 to my friend.This works until unit is dead, or... or I don't know it causes desync when there are some other units.(maybe enemy units while checking priority for w3 AI, but there was a neutral hostile unit and it didn't cause desync until footman dies.)

Troll-Brain · Sep 15, 2011

In general it doesn't descyn until the result "game" is the same.
I've already given successfully different positions for players with SetUnitX/Y, it did cause desync only when the unit was attacked (well there are probably many other cases like enter in range, region, ....).

But your result is quite surprising, that would mean life of units is not (always) synchronized, weird.
