[SOLVED] Logical Expressions Question

[Maximus]

How do logical expressions work in GML? For example, with an if statement like this:

if ( <expression 1> && <expression2> )
{
    // do something
}

if the first expression evaluates to be false, will the second expression be evaluated or just skipped over?

If <expression2> was particularly taxing to evaluate, and <expression1> is rarely true, then should I make it a nested if statement or is this unnecessary?

if ( <expression 1> )
{
    if ( <expression2> )
    {
        // do something
    }
}

GML stops evaluation when it runs into something that results in false. They made a blog post about this when they changed how GML evaluates things.

Awesome, thanks. The blog only mentions &&, can I also assume short circuit evaluation applies for || when an operand is true?

That's incorrect, as it won't be able to determine if the entire expression is false until it evaluates all || operators.

Edit: *facepalm* ... Actually read what you asked this time. Yes, that is true. Ignore my dumb arsed initial comment.
