[JASS] What type of local is this??? Version?

[sephiroth1234]

Hi... May I ask what is the purpose of this local variable 'version'. I discovered this variable when I try many times creating local variable with different types, and then when I entered a custom script line that reads "local version v". Unexpectedly the WC3 engine accepted the variable type 'version'. I think its the game version like 1.24d and 1.24e but I don't think that's it or I am lacking clarification about that.


Thanks for someone who will clarify this for me and of course +rep!!!

It shows RoC or TfT depending on what game you're running.

Then how it is used in-game???

It's used for the melee triggers that you see the first time you open trigger editor in a new map.

Specifically:

function MeleeStartingResources takes nothing returns nothing
    local integer index
    local player  indexPlayer
    local version v
    local integer startingGold
    local integer startingLumber

    set v = VersionGet()
    if (v == VERSION_REIGN_OF_CHAOS) then
        set startingGold = bj_MELEE_STARTING_GOLD_V0
        set startingLumber = bj_MELEE_STARTING_LUMBER_V0
    else
        set startingGold = bj_MELEE_STARTING_GOLD_V1
        set startingLumber = bj_MELEE_STARTING_LUMBER_V1
    endif

    // Set each player's starting resources.
    set index = 0
    loop
        set indexPlayer = Player(index)
        if (GetPlayerSlotState(indexPlayer) == PLAYER_SLOT_STATE_PLAYING) then
            call SetPlayerState(indexPlayer, PLAYER_STATE_RESOURCE_GOLD, startingGold)
            call SetPlayerState(indexPlayer, PLAYER_STATE_RESOURCE_LUMBER, startingLumber)
        endif

        set index = index + 1
        exitwhen index == bj_MAX_PLAYERS
    endloop
endfunction

native VersionGet takes nothing returns version

Theres a constant for ROC and TFT, a function to convert an integer to a version (but no function to convert back), a function to compare the version you're running to a version variable, and a function for whether its supported (I guess that returns true for TFT only if youre running TFT, but returns true for ROC if youre running ROC or TFT).

Thanks!!! +rep to all who clarified it!

I have to say I have never used this, ever, nor did I even know about it. But, there is something that hasn't been mentioned.

(but no function to convert back)

Not true. If you use GetHandleId(VERSION_FROZEN_THRONE) it will return 1 (just as ConvertVersion(1) will return VERSION_FROZEN_THRONE.

By the way, why is it that anything with bj_ is highlighted as a constant? Also notice that the "0" and "1" at the end of bj_MELEE_STARTING_GOLD_V0 is not highlighted despite being apart of the constant's name.

bj_WHY
bj_CAN
bj_I
bj_MAKE
bj_MY
bj_OWN
bj_CONSTANTS?
