What about a translation library?

[Pinzu]

It should be pretty straight forward to switch languages now that all (most) of the UI components are changeable. I am myself too lazy to do all of it, but I did create a basic manager for all strings using a table array, as well as translation binding to unit types.

This library only allow you to configure different language definitions which you can use to update the UI using wrapper methods for SetUnitName, SetItemName, SetAbilityTooltip, and so on. It does however not automatically update strings when the language is changed (except for units entering map). Not sure if I should keep this feature, expand on it or remove it entierly.

Not sure exactly how to handle the HeroProperNames, though one can use the wrapper method to override the Object editor proper name.

If you happen to have an idea of why the extended research tooltip is being clipped do tell.

Finally, do post the natives that let you change labels of unit/items being sold/trained, can't seem to find them.

 

[Frotty]

I think it's a cool idea, but without some form of automation it seems cumbersome.
Also why not follow some existing standard like i18n?

 

[Tasyen]

Nice work but to me it looks like you are recreating wts-Files in vJass, unsure how effective that is.

Afterall WTS-Files already have multilanguage support which (almost) nobody seems to use: Reason could be it's a quite hidden undocumented feature, it is slow and most projects are english-only anyway.

Wouldn't underestimate the effort to create a MultiLingual map.
You have to externalize all user relevant text of your code and write 1 clone for each supported language, that is alot of work.

Object Editor Data is already externalized lucky.
GUI people have it easier in that aspect cause their raw text is already externalized except for this fused String actions. (String A + String B)​

With the wts-Files you have the advantage that you can send it to anyone and he could translate it, even if he can not read (v)jass. Cause the format of wts is quite easy.
Also warcraft 3 manages the usage of wts automatically.

Im uncertin in what way I'm breaking the standard except for the IDs being unlabeled. Care to elaborate?

Think the problem with merchants can be solved by limiting units and items available to certain players, and simply translating in the object editor, then when they enter the map they are manageable again.

The problem with automation is that you can't keep track of all existing items and displayed text messages/labels. The user would still have to handle that himself so my thinking is, either it can automate all (unit types, hero names, items, item types, abilities) or nothing. But maybe my thinking isn't straight here. I could add a real variable event change for when language is changed.

I'm not sure you can change the language in game, are you talking about shpping different coppies oft he same map?

 

[WaterKnight]

And here I thought you would use a translator service like Google Translator to convert all the strings The original data could, of course, be mined. Maybe you don't have to update everything in one go but on demand.

 

[Tasyen]

I'm not sure you can change the language in game, are you talking about shpping different coppies oft he same map?

You shifft different copies, if you have inlined strings and got rid of the wts-File for whatever reason ,proably loading speed. Then you can translate the txt files and the game will still detect them as the same map. Problematic may text hardcoded in your code.

If one is using wts-Files one can add 1 wts-file for each supported language into the map (by mpq Editor) each of the wts files is named "war3map<Lcid>.wts". the default neutral one is just "war3map.wts" it is used if none for the own language is found.

German for example is "war3map#0407.wts" ("#0407" managed by the mpq if one uses the set localize button problematic is adding them with the mpq editors gui, if you added the neutral english one first).
If there is "war3map.wts" and "war3map#0407.wts" in a map, any german warcraft 3 player will load the triggerstrings from "war3map#0407.wts" while others see the text from "war3map.wts".

Edit: This wts-File feature was broken from V1.29 to V1.30.1

I could need some help in figuring out a method for extending the string length in a translation and why the research tooltip is not showing up correctly. I've provided a test map for you to look at.

You are my only hope.

--------------------------------

I also added UnitLimtiTranslator so that trained units can be restricted depending on which language the user has. It's problematic in the sense that one would need to maintain multiple object editor units for each real unit. When they enter the map they also need to be replaced with the "real unit". Aditionally the tech-tree poses another problem which I wont touch. Any feedback on most convenient implementation?

Note: This is also applicable on items sold.

And here is an example of how toggling between the two would look like:

scope TypeLimitExamnple initializer Init
 
    globals
        private TypeLimitTranslator languageLimiter
    endglobals
 
    private function OnChange takes nothing returns nothing
        local player p = GetTriggerPlayer()
        call TypeLimitTranslator.updateAllPlayerUI(p)
        set p = null
    endfunction
 
    private function Init takes nothing returns nothing
        local trigger t = CreateTrigger()
        call TriggerRegisterVariableEvent(t, "udg_languageChange", EQUAL, 1)
        call TriggerAddAction(t, function OnChange)
   
        // Unit Types
        set languageLimiter = TypeLimitTranslator.create(EN, 'hfoo', TypeLimitTranslator.UNLIMITED)
        set languageLimiter = TypeLimitTranslator.create(SE, 'h000', TypeLimitTranslator.UNLIMITED)
        set languageLimiter = TypeLimitTranslator.create(EN, 'hrif', TypeLimitTranslator.UNLIMITED)
        set languageLimiter = TypeLimitTranslator.create(SE, 'h001', TypeLimitTranslator.UNLIMITED)
   
        // Item Types
        set languageLimiter = TypeLimitTranslator.create(EN, 'mcri', TypeLimitTranslator.UNLIMITED)
        set languageLimiter = TypeLimitTranslator.create(SE, 'I000', TypeLimitTranslator.UNLIMITED)
   
        call TypeLimitTranslator.updateAllUI()
    endfunction
 
endscope

            call thistype.instances.add(thistype.instances.size(), this)
            set this.languageId = languageId
            set this.typeId = typeId

                    call ReducePlayerTechMaxAllowed(p, this.typeId, this.normalLimit)
                else
                    call ReducePlayerTechMaxAllowed(p, this.typeId, 0)
                endif

                set i = i + 1
            endloop
        endmethod
   
        private static method onInit takes nothing returns nothing

        endmethod
    endstruct
 
    struct UnitTypeTranslator
 
 
    endstruct
 
    // Need hooks for changing player unit type limits...

The problem with limiting types currently is that you cannot limit it to neutral merchants even if it works fine for player buildings (as seen below). The reason is that the limit native appears to only work on units trained and items made and not on units sold and items made.

I'm not sure yet of what the best method is to circumvent this problem.
