Hashtables and MUI

[Vercas]

To the Get Handle ID part, I can only give a handle variable.
Is there any way to convert an unit to a handle?

 

[Deuterium]

A unit is a handle... but in case in GUI the conversion isn't allowed, just use the Jass version:
set <your integer variable> = GetHandleId(<your unit variale>)

 

[Vercas]

Lol, I skipped GUI and made my spells vJASS with the hashtables.

I hate messing around with both GUI and JASS.

 

[meercat]

I pretty understood how hashtable works thanks to this tut.. But the problem is when you do things by your own, im completely clueless how to work hastable out.

And what happens if you clear the parent hash? and what's the difference of clearing parent and child? isn't it better to clear the child? also, if you would just delete a point/location then does it mean that hashtable is usesless when your trigger contains point/location? So you'll just use indexing for the point? But then again isn't Hash better..

It really gets confusing when you're doin the hash alone.

Or I would just post my spell and ask people how to screw the hash on it?

 

[Adiktuz]

now I kinda understood how hashtables work especially on making Over-time MUI spells...

 

[Adiktuz]

how do you set "keys"? when I try to use the hashtable and pick the preset key is looks for some handle variable, then I try to create a handle variable but I can only set it to another handle variable..... I don't kinda understand, but take note that I haven't tried to proceed from there...

 

[Adiktuz]

So... if this does what i think it does... it can be used as a save system for orpg maps? O.ô

If you're thinking about saving the data in the hashtable, quit the game then start again and type a load code or something to retrieve the data... then NO... I heard the data stored in the hashtable is deleted after the game ends so you cannot retrieve anything you stored in the hashtable after quiting the game....

You cannot even use hashtables for transitions in campaigns..

 

[Sheepo]

And I've been using custom value of unit in array variables to keep track of data for specific units in my map... thanks for the tutorial.

 

[pick-a-chew]

I'm curious, lets say you have made 100 spells using their own hash table, and are triggering periodically every 1 second - wont that make some form of lag, or atleast decrease the game performance?

 

[Element of Water]

Every 1 second? Unless they're really complex ones, no, it shouldn't lag at all.

 

[Deuterium]

Also if there's lag it shouldn't have anything to do with hashtables...

 

[rover2341]

Eh, I dont fully get it.
I learned in class hash tables were primarily used to accuses data quickly, but that is not in order.
Is the concept of using this better for MUI purposes? Storing more things that's allowed then in a array?
I don't fully see the advantages in using it in a warcraft map. I also dont fully understand them. Ill try to reread what he has Typed down again...

*I found some stuff nm.

The major advantages of the hashtables are:

1) no limit on the index, arrays are limited to a max of 8190.

2) it's two dimensional

3) you can get the handle Id of most any object.

4) If your not sure where your value is stored in a array, using a hash tables can bring you straight to it.

5) For GUI Easier To get MUI Functions.

VERY nice

Yeah, I don't either understand how you go the "(Key (Target unit of ability being cast))" here:

• Hashtable - Save 10.00 as 0 of (Key (Target unit of ability being cast)) in hashTable

Since if I check that, even in the Hashtable Tutorial map in the first post, I still can't pick "(Target unit of ability being cast)"... What is wrong ?!

 

[Maker]

Select Hashtable - Get Handle ID, and then click on Key (Last Created Unit). Browse for Event Response - Target unit of..

If that does not work then try reisntalling.

 

[Komaqtion]

Reinstalling what ?! :S

I've now been told that the GUI hashtables doesn't work with Newgen :S
Is that true ?

 

[Adiktuz]

I think so because Newgen is what I use and when I click the Key(GetHandleID) the only menu that is present is that of the variables.... but anyways it works fine with JASS though the TESH i'm using right now doesnt have a list of the hashtable functions, I needed to make them in a blank GUI trigger then convert to custom script to get the functions....

 

[Windu]

Ok, that tutorial is Really helpful!! Thanks to the creater! (+rep)

But I have 2 questions:
1. WE Unlimited does not support hastables and does not load a map with these functions. Is there a version of WEU that does support them ?

2. Edit: Figured it out.

don't use WEU...

There is one thing i don't get it. RemainingTime is global var. So if i cast a 2nd healing over time within 10seconds. the 1st unit who benefit from it will get have its Healing over time reset to 10? Since storing the hashtable value to a global var which is 10 and it will reset the condition. Correct me if i am wrong.

If I'm right....

If you are talking about if casting the spell into another unit will reset the first unit's timer then no because the actions of the periodic event happens in a loop with instant actions so every run will not override the other..... and for every run of the loop the variable RamainingTime gets its value changed depending on the stored value in the hashtable that are specific for each unit..

but if you're asking about if the spell is casted into the same unit then the timer will go back to 10 for that unit....

 

[aaron]

this tutorial is bugged on the knockback part, i tried it and i noticed that the units will be pushed forever without stop since in the loop every .04 seconds it RESETS the time variable so it will actually never end.

 

[Maker]

^I'm not seeing the bug. The value is loaded, then it gets saved after 0,04 has been subtracted from it. So eventually it will become less or equal to 0, and the unit stops.

 

[calex3]

If I create hashtable and when spell is finished i need to destroy it....do I need to use custom script or I just need to use some function

 

[Element of Water]

You cannot destroy hashtables. Even with custom script.

 

[nKnight]

I'm being honest

I don't understand some of it( maybe cuz i'm still a noob )

 

[valkemiere]

how about remove leak in 1.24. coz removelocation didnt work at 1.24 i think

 

[scorpion182]

how about remove leak in 1.24. coz removelocation didnt work at 1.24 i think

it still works because it never changed.

 

[kelek2]

so if i use hashtables they are completly MUI?

 

[Maker]

If you use them correctly, like don't overwrite handles.

 

[terradont]

Great tutorial. Made my triggering a hell of a lot easier. I would never figured this out by myself.

 

[Xbing]

whats MUI? sorry im a noob.

 

[SlayerII]

Google is your friend!
edit: ok.. Mui means that a spell could be used by multiple units at the same time. If you code bad, than it may happen that if 2 units are casting the spell at same time that there will be a bug. If your spell is MUI that wont happen.

 

[Xbing]

oh! then in that case i think i know why, its because it creates a key for every single unit that casts the spell but it wont leak beacuse u kill the child keys. then... its damn powerful....

 

[Wardragonkai]

hi i dont quite get it yet but i somehow understand alittle bit can it be simplified a bit me newbie

 

[Wardragonkai]

great my patch does not have this what patch is it?

 

[nerovesper]

just a question. if the code is done like in the healing tutorial, the healing then does not stack, right? like overriding with the same buff? I just thought this because the target unit is the one being stored. if i didn't miss something... xD

 

[Maker]

The healing doesn't stack, meaning you won't get 2x HP. The timer gets renewed if the heal is still going on, since you overwrite the timer value. So if you have 2 seconds of healing time left and the spell is cast on the same unit again, the timer will be set to 10 again.

It is possible to code it to stack by using integers for example, to keep track how many instances of the spell are running on the unit at the same time.

 

[M_Vegeta]

well i have read the whole tutorial and i found it uncomplete : i tryed few time to make complicated spell in hashtable which caused strange but like : if there is no picked unit in group the part of the spell wont run and the spell will end + hashtable has been found slower than integer , they arent so e-z to use or any faster : The dynamic index found in hanke template can made spell mui in a copy, paste and variable renaming.....

hashtable are good but i still think poeple should learn indexing or index their hashtable or even BETTER USE vJass

 

[88WaRCraFT3]

I have an problem, i can't get that handle ID like picked unit or target unit of ability being cast.

 

[Maker]

Are you using JNGP?

You can always use custom script:

call SaveUnitHandle( Hashtable, GetHandleId(u) , StringHash("target") , t)

u is either a variable, GetEnumUnit() or what ever. T is the unit whose handle you want to save.

 

[88WaRCraFT3]

Ok, that means that i can't use JNGP? whatever thats just to update my shadow walk.I will edit it in normal WE.

 

[orcyngiser]

that was really helpful thx

 

[nerovesper]

I have an problem, i can't get that handle ID like picked unit or target unit of ability being cast.

you meant this?:

JNGP Bug

maybe you could try this:

I don't know if this will work but you can try extracting the UI folder from war3patch.mpq and placing it in your warcraft folder.
This should update your GUI functions and such.
As for an updated TESH, download horus. It's just a lame name for an updated TESH.

I tried updating that Tesh and it worked for a while but suddenly it bugs again that's why i just use normal WE when using hastables now. but it might work for you hopefully...

 

[88WaRCraFT3]

Ok thanks.

 

[Cardinian]

probably the most informative tutorial on this site.

I only do War3 modding in GUI. But I do know some scripting and programming languages, just havn't been so bothered with Jass.

So, thanks to this, I can now do fancy stuff in my maps without having to bother Pharaoh_ or other people who reply to me on the World Editor Help Zone .

 

[sephiroth1234]

Not only with healing and knockback spells Hashtables will do..... But also you can create a GUI MUI Tree Revival System like this and it only requires 2 triggers and one(1) Hashtable global:

• Initialize Tree Revival Hashtable
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Hashtable - Create a hashtable
    • Set TreeRevivalHashtable = (Last created hashtable)
    • Destructible - Pick every destructible in (Entire map) and do (Actions)
      • Loop - Actions
        • Hashtable - Save 0 as (Key tree counter) of (Key (Picked destructible)) in TreeRevivalHashtable

• Tree Revival
  • Events
    • Time - Every 3.00 seconds of game time
  • Conditions
  • Actions
    • Set EntireMap = (Entire map)
    • Destructible - Pick every destructible in EntireMap and do (Actions)
      • Loop - Actions
        • Set TreeRevivalLocation = (Position of (Picked destructible))
        • Set TreeRevivalGroup = (Units within 300.00 of TreeRevivalLocation matching (((Matching unit) is alive) Equal to True))
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Number of units in TreeRevivalGroup) Equal to 0
            • ((Picked destructible) is dead) Equal to True
          • Then - Actions
            • Custom script: call RemoveLocation(udg_TreeRevivalLocation)
            • Custom script: call DestroyGroup(udg_TreeRevivalGroup)
            • Hashtable - Save ((Load (Key tree counter) of (Key (Picked destructible)) from TreeRevivalHashtable) + 3) as (Key tree counter) of (Key (Picked unit)) in TreeRevivalHashtable
            • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
              • If - Conditions
                • (Load (Key tree counter) of (Key (Picked destructible)) from TreeRevivalHashtable) Greater than TIME INTERVAL OF TREE REVIVAL
              • Then - Actions
                • Destructible - Resurrect (Picked destructible) with (Max life of (Picked destructible)) life and Show birth animation
                • Hashtable - Save 0 as (Key tree counter) of (Key (Picked destructible)) in TreeRevivalHashtable
              • Else - Actions
          • Else - Actions
            • Custom script: call RemoveLocation(udg_TreeRevivalLocation)
            • Custom script: call DestroyGroup(udg_TreeRevivalGroup)
    • Custom script: call RemoveRect(udg_EntireMap)

 

[Cardinian]

Couldn't you do the exact same thing with:

Every 3 minutes of game time
custom script set bj want destroy group = true
pick every destructible matching, type equal to tree and matching, condition boolean:: dead equal to true
replace picked destructible with tree living.

Picking destructibles is not like picking units... When you are trying to revive a destructible, the WC3 engine understood that the destructible is a tree because trees are the only destructible can be revived. The condition of the trees must be in another loop and why did you created that damn custom script line: set bj_wantDestroyGroup = true since the objects I picked are not units. So don't create that line for two reasons:
1. They are not units
2. Picking destructibles don't create irritating leaks... Got it?

Greate tutorial. I have tried to find a good MUI tutorial in the last couple of days, but it was with arrays and i didn't understand the hole thing.. I total understood this, so thank you very much. Can finally create MUI spells ...
