Variables. What the he.............

can u guys please explain to me what variables are? and give me and example of how to use? they are so confusing:bgrun: :bgrun:

Variables are very useful, you'll learn more about them when you get to higher math classes.

A variable can be anything, a name, a number, what not. For this example, let's say our example variable is a number (called an integer in Warcraft 3).

A variable can be set to anything. Let's set it to 3.

So the equation 2 + Variable = ?, will equal 2 + 3 = 5.

If we set the variable to 7, the answer will be 9.

A variable is something with a value that is not fixed.

Sorry, It's kind of hard to define a variable. After a while, you just know what it is.... it's really hard to explain...

For a Warcraft 3 style, let's take the following example

We have a unit variable. That means this variable can be any unit on the map. It's kind of like a mask that we put over one unit, to mark it.

Let's say we want player 1's hero, to be removed. You may be thinking, why can't I just select the unit when I place it on the map, instead of going through this variable nonsense.

But what if the hero changes in the middle of the map? Say he evolves into a higher form of being and becomes a completely different unit. When he evovles, you can say Set UnitVariable to (Last Created Unit).

So let's look at the trigger.

Events - Player 1 Types 'Vanish' as an exact match

Actions - Remove UnitVariable

This'll remove the unit that's under the 'mask' that we put on him...

I hope that explains it, somewhat.

Has good explanation

but how do u make the variable target a specific unit? is it tihs way: lets say the guys name is sword man. so would the variable be named swordman? and i would choose from the drop down list unit type? is that right?

I just edited mine, I added a wc3 exmaple... I hope that clears it up...

but how exactly do u make them(besides going to the menu and clicking new variable), like choose a specific unit. ive spent alot of hours on tftwe and the only thing i understand from variables now is that its some sort of an equasion or recipe in acookbook or something

There's an acition called Set Variable... you can set the variable to wahat you wish... that's how you would set it....

Sorry, it's REALLY hard to explain.
