please continue developing as you please and ask any questions,
common uses:
check if expression was typed
cheats
other nifty similar stuff
instructions:
first of all create a new instance of the class by typing
my_keyqueue=new KeyQueue(<your max length here>);
//the longer the max is the bigger cheats it can contain and the more usage it takes
my_keyqueue.listen();//starts key queuing
//actual checking for cheats
this.onEnterFrame=function(){/*if in movieclip put anything before this in a onClipEvent(load) and everything from now on in an enter frame*/
if(my_keyqueue.cheatCheck("hey lolz"){//replace hey lolz with your cheat
//actions that trigger when cheat is true go here
}
you can use this for a lot more than cheats
this is a pretty simple docs I just whipper up:
NOTE: inherits from the MovieClip class to enable pathing (passing this to the listener)
properties:
innerQueue :Array;
this is the actual queue the data goes in and out of. this is encapsulated so apart from knowing it's there it's not really an interest
constructor:
KeyQueue(length:Number)
creates a new KeyQueue the length of the passed parameter
Functions:
function getLastKey(Void):Number - returns the last typed key, pretty useless but it makes sense to have it there, type my_keyqueue.getLastKey(); to get the last user typed key
function listen(Void):Void -starts the actual watching over the user keys, use this to activate the actual capture
function getKeyFromQueue(pos:Number):Number - returns the pos key typed, for example if you typed omg, getKeyFromQueue(17) would return 'o' I believe in a 20 sized queue,
function toString(Void):String - convers the current KeyQueue to a string, usage: trace(my_keyqueue.toString);
the qts function is irrelevant, it basically does what toString does but being private you can't access it
function wasTyped(expression:String):Boolean - checks if the last expression typed is equal to the passed string for example wasTyped("hello") returns a boolean true if the last typed thing was "hello"
public function cheatCheck(expression:String):Boolean -identical to wasTyped
enjoy the code :)
(simple code instructions: copy contents into a new file, call it KeyQueue.as , the name is IMPORTENT, any other name WILL CAUSE A FAULT, put it in the same directory as your .fla file, the output will still be one .swf file, don't worry)
