Variables Tutorial
Welcome to my Tutorial about Variables!
This tutorial is made for anyone who need help with Variables. The list here
is long, but also really noob-friendly, so anyone should understand what I am
teaching you
Please note that this is JUST MADE FOR VARIABLES! The examples I give
may contain leaks and such, but I only made this for the Variables sake!
Feel free to ask if you have Questions!
Ok, so lets start!
I WILL SOON UPDATE THIS THREAD!
This tutorial is made for anyone who need help with Variables. The list here
is long, but also really noob-friendly, so anyone should understand what I am
teaching you
Please note that this is JUST MADE FOR VARIABLES! The examples I give
may contain leaks and such, but I only made this for the Variables sake!
Feel free to ask if you have Questions!
Ok, so lets start!
Step 1 - Getting Started
If you open your map and click F4, your Trigger Editor should open.
Now press CTRL+B to open your Variables. Now, to make an Variable,
simply click the Green Button (or press CTRL+N = New). An new window
should open where you need to type an Variable name, select an type and
check if you want Array Enabled or not.
So, just type any name you want, and select the type "Ability" and move
on to the next step in this tutorial.
Step 2 - The "Ability" Variable
Heres an example of an "Ability" variable:
So, what does this do?
Variables
Events
Conditions
Actions
Set Ability_Variables = Attribute Bonus
At the "Action", you Set an Variable that you have created.
To do this, create an new action and scroll down to "Set Variable".
Select the Variable you did in Step 1 and select an wanted Ability that
the variable should become!
Here is an example when this could be needed:
The Event here is that an Unit (maby your hero or such) starts the effect
Unit - A unit Starts the effect of an ability
(Ability being cast) Equal to Ability_Variables
of an Ability (the unit is ordered to cast an ability), and the Condition here
uses the Variable you have done.
The (Ability being cast) Equal to "Ability_Variables" is equal to the ability
you set your variable to be. So, here you use your Variable that you have
made, to be used instead of an direct ability.
Step 3 - The "Attack Type" Variable
Here is an example of an "Attack Type" variable:
It's the same basics here, you make an new Variable, name it whatever
you want (i named it "AttackType_Variables") and select the type or Variable
to Attack Type.
In this Action, you set your new Variable to be an Attack Type of Spells.
You can use this Variable when you order your Unit to attack another
unit, something like this:
So, the event here is that an Unit is ordered to attack another unit, when
it does, it will deal 500 damage, of type "AttackType_Variables", what
type is that?.... Spells! We set the Variable to be Spells, right?
This is just an example, you kinda dont need this Variable alot, but I must
teach you right?
Step 4 - The "Boolean" Variable
This is one of the most usefull Variables, so I will give alot of examples,
some may seem advanced and such, but I will explain it all for you.
Ok, so this is how an Boolean Variable looks like:
It checks if something is "True" or "False". So this is what I want you to
do: Go to Variables, create a new one with any name you want and type
Boolean, and do as I will show.
We will now make an easy example of when you might need an Boolean
Variable.
So, heres what I want you to make:
1: an Event
Make it like this:
The Event here is that Player 1 (Red) types "HELLO" in a message.
Player - Player 1 (Red) types a chat message containing HELLO as An exact match
2: Now to the Boolean Variable, it should be like this:
Ok, the Conditions here will check if your Boolean Variable is "True" or
"False", and now we will make use of this in...
3: Create an Action for this, you can make any action you want, but this
is how my example looks like:
So, we have now made the Game Pause if the Boolean is "True".
Game - Pause the game
So, if it is "False", it will not Pause the game, you following?
We can use this for eaven more, make another Action, and set the boolean
to "False", like this:
So, the Boolean Variable is now set to be False, so now when Player 1
types "HELLO" again, it will not Pause the Game longer, since the Boolean
is not "True", it is "False".
Here is an more advanced example of where you could need an Boolean:
Here I use "If - Then - Else" actions, so "If" the Boolean Variable is "True",
Special Effect - Create a special effect at (Position of (Casting unit)) using Abilities\Spells\Human\Thunderclap\ThunderClapCaster.mdl
the unit will damage another unit. "Else" (if the Boolean is False), the unit
will not damage another unit!
So basicly, when an unit uses the spell once, it cannot use it again with
dealing the bonus damage.
We could talk alot about this, but we need to move on.
If you have any Questions, feel free to ask!
Step 5 - The "Buff" Variable
Buffs can be found in most spells.
What is does, is that it gives information about the spell that an unit
is under. An example of this is Bash. When an unit gets hit by the Bash,
it will get an "buff" that says "This unit cannot move" and an icon next
to it.
Here is how it can look when you make an Buff Variable:
So what's done here, is that you make an Variable of type Buff.
You can also create custom buffs in the "Object Editor" (F6).
You mostly use buff Variables for things like this:
You can also use this Variable for Effects, that also can be created
in the Object Editor.
