How to use "Boolean" - mrkiller90 - 17.07.2014

So my problem is that I saw in some tutorials people writing something like this " ? true : false ", I wanna know how to apply this in my code because I am simply writing " HouseInfo[i][hOwned] == false " and it's not working when I save it.

I just wanna know if the problem is on the boolean because not using that thing " ? true : false " or is in the saving system.

Help is appreciated, thanks (:

Assigning to true or false is just "= true;" or "= false;"

Only use "==" when comparing.

Or you can do it like this aswell:

pawn Код:

new bool: variable;

// Variable is true:
if(variable)
{

}


// Variable is false:
else if(!variable)
{

}

Might be the loop you've done before or the saving system.
Any errors?

No, I got no errors at all (the bool is at the enum)

? true : false is called ternary operator.

It's a easy way to replace this:

pawn Код:

if(condition)
{
    var = value;
}
else
{
    var = anothervalue;
}

With this:

pawn Код:

var = (condition) ? value : anothervalue;

'?' = if the condition proceeds
':' = else

Some examples:

pawn Код:

new value = 5;
new bool: isfive = (value == 5) ? true : false;

pawn Код:

new string[] = "hello world";
new bool: isempty = (strlen(string)) ? false : true;

pawn Код:

new Float: value = 0.0;
print("The float value %s.", (value > 0.0) ? ("isn't null") : ("is null"));
