Pretty much a good one, but ain't it's better as a tutorial with the map attached at the end? (Unless there's some exclusive codes in this system).

Was thinking about that as well, but somehow I see it more presented globally here, more people will find it here.
Also dunno how good it is as tutorial.

 

[vypur85]

Pretty surprised there isn't any pseudo local 'tutorial' in Hive yet. Or is there...?

Perhaps you could mention that the pseudo local method can only work for a single global variable.

Also, pseudo locals do not really work in GUI condition block. This can easily be solved by globalising the local again.

Yeah any GUI code that split function (conditions for example) won't work here.
Will show way around as you mentioned.

Thanks.

man, this is not a system..
uhm, I don't know so much but, is there any difference between local without and with udg_? sorry to ask here

edit:
oh, or if I get this right, you localize a global variable?

Yeah.

 

[Kazeon]

well, could be great if there is no limitations like

can only work for a single global variable.

:/

 

[-Kobas-]

Then you create another global variable.
If you need 3 unit variables.
Create unit1, unit2, unit3 udg variables and use 3 custom script lines

 

[Kazeon]

how about variable with array?
if it's integer array named udg_i then, can it work with local integer array udg_i?
I'm noob, so much question in my head :3

Jass New Gen throw error, saying you can't use that name (it's already taken).
You can use custom jass variable (that will be fine) but you can use this variable in GUI, like you do with udg_ variables where you click on blocks and shit.
You will need to stick with custom script in this case.

 

[Kazeon]

lol I understand, thnks.. good job with the system, I will rate this 4.75253035720 / 5.0 : little bit highly recommended

btw, gui is poor, I wont use it XD

 

[IcemanBo]

Very funny test map, enjoyed watching all explode. :d

I think it would be good also to make test triggers leakless, since you clean locals, but you leak globals. (locations/effects)

Apart from if this is right place in spell section or not, this might be useful. And it's good that you created a long list with custom script examples.

What maybe would meaningful to note is that "TriggeringUnit" and "DyingUnit" already can be treatet like local, and so no extra local variables have to be created for them.

 

[Maker]

I think this is much too simple. Personally I don't support shadowing globals. The wait can be troublesome in multiplayer.

 

[nhocklanhox6]

This is a cool trick ^^, it will help some people get out of the trouble with JASS & GUI compiler...

Check the map below, why I can local them ? >.<

Code

• Dash
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
  • Actions
    • Custom script: local integer udg_II = 0
    • Custom script: local unit array udg_U
    • Custom script: local integer array udg_I
    • -------- ---------------------------------- --------
    • Set II = (II + 1)
    • Set I[II] = (Random integer number between 1 and 100)
    • Set U[II] = (Triggering unit)
    • Set II = (II + 1)
    • Set I[II] = (Random integer number between 1 and 100)
    • Set U[II] = (Triggering unit)
    • Set II = (II + 1)
    • Set I[II] = (Random integer number between 1 and 100)
    • Set U[II] = (Triggering unit)
    • Set II = (II + 1)
    • Set I[II] = (Random integer number between 1 and 100)
    • Set U[II] = (Triggering unit)
    • Set II = (II + 1)
    • Set I[II] = (Random integer number between 1 and 100)
    • Set U[II] = (Triggering unit)
    • Set II = (II + 1)
    • Set I[II] = (Random integer number between 1 and 100)
    • Set U[II] = (Triggering unit)
    • Set II = (II + 1)
    • Set I[II] = (Random integer number between 1 and 100)
    • Set U[II] = (Triggering unit)
    • Set II = (II + 1)
    • Set I[II] = (Random integer number between 1 and 100)
    • Set U[II] = (Triggering unit)
    • Set II = (II + 1)
    • Set I[II] = (Random integer number between 1 and 100)
    • Set U[II] = (Triggering unit)
    • Set II = (II + 1)
    • Set I[II] = (Random integer number between 1 and 100)
    • Set U[II] = (Triggering unit)
    • For each (Integer A) from 1 to II, do (Actions)
      • Loop - Actions
        • Game - Display to (All players) for 30.00 seconds the text: (String(I[(Integer A)]))
        • Game - Display to (All players) for 30.00 seconds the text: (Name of U[(Integer A)])
        • Set U[(Integer A)] = No unit

 

[Chaosy]

This is really nice.. so if I use this method the variable will be locally created but you can use the variable as a normal GUI variable? (in the trigger it is created that is.)

Exactly.
And you can use same variable in many triggers.

You can't define arrays like this, compiler will throw error.

 

[IcemanBo]

As Maker said now, I also remember having read that it can cause some problems sometimes, so it is a neat trick but in general it's maybe better just to code properly.

Here is the link - http://wc3jass.com/wiki/page/Local_variables_shadowing/

I can save it without any error, i put a test map below , you can test them >.<

Yes you can and it works here for me.
But you can't save it with Jass New Gen.

@IcemanBo
That's a bummer.
I never had any problems with it so far, but will add notice or 2 about this as well.

 

[Malhorne]

Deathismyfriend tutorial talk about this.
Also I truly think this belongs more to tutorial section ^^

Yeah it's something that is well known for several years now, but still dunno why,
when I explain this to GUI users in Triggers & Script forum section for example,
people have no idea what am I talking about...

Programmers that know jass won't have much of use of this and jet they know
about this, but GUI coders that should benefit and exploit this, have no idea.

I have updated resource with suggestions you guys posted and added extra
"chapter" for those who want to know more and use custom script to create
functions and shit.

 

[defskull]

I'm often use this as laziness to make a proper MUI syndrome kicks in.
But I never thought it would be posted as a... resource ?

I'd highly suggest it should be posted in the tutorials section or some sort.
Afraid it will not famous ?

Don't worry !
Link it in your signature OR ask for it to be sticky-ed

Again, this should be tutorials for both beginner and intermediate triggerer, I mean method like this doesn't get exposed to public I guess.

 

[Noobsmoke]

So, is this recommended ? It is risky ? Will it cause desyncs ?

 

[Malhorne]

It isn't risky or anything.

 

[-Kobas-]

Personally, I never had any problems with this. But I left warning just in case.

If you want to keep things extra safe, each time you save map save it as
new one or switch between few saves. I do this mostly because problems like,
losing electric power while saving map (making map damaged in process).

 

[Chaosy]

really? that's really epic...

I will try to remember this then, really useful. rep+

damn true! I also did that...

 

[Magtheridon96]

The Spells section is for spells and systems, not tutorials.
This belongs in the tutorials section of the site and you know that.

(Unless you can actually make the map nicer and bigger so that this thing is as good as Hanky's dynamic indexing shit)

Will do that.

Knowing you, you're going to do the second one

This is already all explained in my tutorial though.

[BPower]

First of all I'm not really a fan of shadowing global variables.

Basically there is no wrong information in the map file and the presentation is also good.
Some rumors say waits can be troublesome for multiplayer seasons, which I can't comment on because I never used this technique.

I'll need the opinion of another mod to make a final descision.

 

[deathismyfriend]

Shadowing globals works fine. Although it is kind of a bug it still works correctly and I have not seen a case where it does not work like a normal local variable would.

 

[PurgeandFire]

I'm going to go ahead and approve this. I apologize for the long wait. Even if this is simple, it is a good template and could prove useful to GUI users.

 

[K.V.]

I find this system very useful and easy to understand, and it helped me in solving the problem with making some item effects MUI. A deserved rating of 5/5...
