Variables - Determining the type you need.

[Gwaith]

I hate to start up my first post with a question, but I need to understand this. I have a basic understanding of programming logic and I only worked in Pascal.

The problem I run into the most often in WE is determining which variable type I am able to use. "No generated variable of this type exists".

Example:
Why can't I use a variable "MaxHealth" of type Integer that stores a unit's maximum health in order to be used in the following instruction?

• Events
  • Unit - Unit's life becomes Less than or equal to ((MaxHealth)/2.00)

I need a way to determine the type of variable I am allowed to use in certain situations.

Maximum health is normally an integer number, you won't see a unit bearing "342.90" as maximum health, it's just turned internally into a real number/value, so that you don't continuously mess up with integer conversions.

So, when you are going to place the max health/2 function, scroll to "Unit - Unit property" and find "Maximum life" of (Unit).
By default, this action accepts real values. If you want to convert values, there is some conversion method of converting reals <-> strings/integers and the other way around.

Aha, thank you sir. Never thought that "Unit - Property" covers that.

A basic programming language will teach us 4 basic knowledge which is:

- String -> A sequence of character which ranging from A-Z , Symbols , etc
Example: Jason , CoW , !!!!@@@!###

- Boolean -> A value that is known as TRUE/FALSE | ON/OFF | 1/0
Example:

• [If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • Boolean Equal to True
  • Then - Actions
    • Trigger - Turn on (This trigger)
  • Else - Actions
    • Trigger - Turn off (This trigger)

- Integer -> Digit(s) which has no fractional parts
Example: 3 , 470 , 23 , 900

- Double (or known as Real in Trigger Editor) -> Digit(s) that has fractional parts
Example: 2.78 , 0.03 , 7564.90
