what's a variable?

[bobo11]

Lol I know what it is ... but how do I use one. Don't link me a tutorial i've read them all.

The main question is ... when you make a variable there is variable type or whatever ... wtf do i select there there's like unit group and umm .. well can't remember there's like 40.

Cheers.

It all depends what you are using it to store.

If you have some units you want to call up later. You can make a variable group and put them in it with triggers.

If you have a hero that you will use often, you can set him as a unit variable making calling him easier.

Just figure out what variable your triggers need and make that type.

you seriously dont actually read a tutorial very carefully

variable makes your trigger easier if you use a lot of actions that contains (lets just say) triggering unit, so if you don't have a variable you have to scroll and search for "triggering unit", but if you have variable, that stores triggering unit, you simply click on it

Its all bout making triggers easier, less messy and for clearing handles

example: u can give a player a variable value like this:

make a variable thats type integer and make it array (12)

well name the variable seppo

now u want to make someones value 3:
action: set seppo(player number of <player>) = 3

then u need the value somewhere. lets say u will want to give him some gold

add seppo(player number of<player>) gold to <player>.

it will give the player his variable worth of gold.

EDIT: not sure if u need to use real instead of integer to give gold

an instance that can have a value of its type
like LOLOLOL is an integer variable and it can be any integer-it can be changed etc

I assume you didn't pass grade 3, or was it 4, when they teach you what's a variable in school (math).

Heres a very basic one. If Variable [IntegerVariable] = 1 then (Something) Else (Something). So many uses for variables actually I couldn't live without them =P. Or..
A unit dies
if owner of killing unit = player 1
set variable: ((player1kills)=(player1kills)+1)) <"player1kills" would be a integer variable>
Then later you could put that in say a leader board. ((LeaderBoard-Set Player 1 Value = (Player1Kills))

Variables can be useful to refer to units you created during a game. If you create a unit set it as a variable and you can manipulate that unit later on without doing it instantly after you created it with last created unit. Set variable: ((Hero) = (Last Created Unit)). <"Hero" is a Unit Variable.>

i dont think variables are teaching in math, it is informatics


ehm,

Real-is the real number, (possitive, negative, decimal, like 4.53, -10.42 ...)
Integer-non decimal number (-4, 1, 0 ...)

They teach you in math variables...

x + 5 = 10    / -5
x = 5

Anyways, a variable can simply hold a value of it's type.
This summarizes all the uses of variables as you can simply use them wherever you can use their value types.

They teach you in math variables...

x + 5 = 10    / -5
x = 5

That's just very simply algebra. The word variable just means something that changes. Antonym = Constant Would Constants be consider a type of math? Just words in themselves really.

 

[bobo11]

Yes I know the definition for variable. And I was talking about warcraft 3 variables. But hey thanks for the useless answers!

The bit I don't get is all the groups and stuff ... don't have we on atm .. but like before it has unit group, unit, player ... ahh you name it. There's quite a few. How do you know which one to select?

Player Group: Add a custom list of players that you want to refer to later. Example add player 1/4/7/12 to player group(cool players) later on you could pick every player in (cool Players) and do functions.
Unit group: custom list of units you want to refer to later. Add peon/blademaster/shaman to unit group(myunits) later you could pick every unit in unit group(myunits) and do funtion.
Unit: Refer to a specific unit later. This is helpful if you want to refer to a specific unit that was created during the game. Normally you would have to use event response (example: triggering unit-entering unit-dying unit) -select unit (unit placed on the map in the WE) or random unit in unit group.
For say a dialog variable you must have one to build a dialog. and a dialog button array (amount of the array would be the amount of buttons you want in your dialog). heres an example.
Create dialog button for (Mydialog) named Start
set variable (diablogButton(1)) = last created dialog button
Create dialog button for (Mydialog) named Stop
set variable (diablogButton(2)) = last created dialog button

Later build a trigger like:
event:dialog button pressed for (MyDialog)
conditionialog button = (dialogButton(1))
Action:Whatever

Special effect variables: Set special effect you created to a variable so maybe 10 minutes later or whatever you could destroy that special effect.

I'm not gonna list them all but I hope this helps.
