PHP Code:

statement ? a : b; 


If statement is true, do a else do b;

?: is a ternary operator (meaning that it is an operator that takes 3 arguments). By itself, the question mark is not a valid operator.

e.g.

PHP Code:

temp.result = SOME_CONDITION ? temp.a : temp.b; 


is equivalent to

PHP Code:

if (SOME_CONDITION) {
  temp.result = temp.a;
} else {
  temp.result = temp.b;
}

PHP Code:

player.chat = "Boots" SPC  (this.boots ? "on!" : "off!"); 


in a script like that, i can see where true is defined, but...

PHP Code:

 player.chat = "Boots "@ ((this.boots = !this.boots)? "on!" : "off!"); 


where exactly was it defined in this?

in some languages, the entire assignment operation [e.g. (this.boots = !this.boots)] returns a value: the value of the left hand side of the equation after the assignment takes place.

In other words, the value of

PHP Code:

(this.boots = !this.boots) 


is equal to the value of this.boots after it is set to !this.boots

edit: I wouldn't worry about all of these little "shortcuts" right now. They make your code less clear, and as someone who is still learning, it is better to be as straight forward as possible.

Right the basics. well thanks again.
