actionscript-3

问题 I am having problems with getting the character to jump/fail when the up arrow is pressed. I'm trying to make it so when the up arrow key is pressed once it will jump a certain height then fall. Here is my movement code: public var gravity:int = 2; public function fireboyMovement(e:KeyboardEvent):void { if (e.keyCode == 37) //right { fireboy1.x = fireboy1.x -5; checkBorder() } else if (e.keyCode == 39) //left { fireboy1.x = fireboy1.x +5; checkBorder() } if (e.keyCode == 38) //up { fireboy1.y

问题 I started reading this tutorial: http://active.tutsplus.com/tutorials/actionscript/creating-a-reusable-flash-uploader-with-actionscript-3-0-and-php/ I'm using FlashDevelop, and I pasted the full code into an ActionScript file. The errors I'm receiving are like this: C:\Users\tempus\Documents\uploaderas\Uploader.as(30): col: 4 Error: Access of undefined property select_btn. select_btn.addEventListener( MouseEvent.CLICK, browse ); ^ C:\Users\tempus\Documents\uploaderas\Uploader.as(31): col: 4

问题 I'm developing an interactive system where two client flash apps will talk to a third server app. The clients will be sending some status information to the server. I think I need two way communication...haven't decided whether the server needs to send back any acknowledgements yet. These will be applications and not .swfs that run in a browser. So far the only method that I see are to make the server an AIR app (b/c AIR has a Server Socket class) and make the clients Flash projectors (b/c

问题 does anyone have any idea what to do in order to find the number of sequences in an array? for example, my array is: var numbers:Array = new Array(banana, banana, apple, banana, banana); and i need to find is: * how many times there is a sequence of "banana" * and the length of each sequence. what shell i do in order to get the following result: 2,1,2 (2 bananas, 1 apple, 2 bananas) i tried with do while loop, but i i guess i miss something. a short example will be very appreciated! thanx 回答1

问题 I'm trying to push just the contents of the "txt" attribute in each "question" tag into an array named "questions" in AS3 Flash.

问题 I've googled a lot trying to find how to properly import and use .swc files in Flash CS 4, tried lots of different methods but none seem to work. What I've done is: 1. Placed it in my "D:\Program Files (x86)\Adobe\Adobe Flash CS4\en\Configuration\Components" folder. It does however not show up in the component inspector. 2. Added it in Publishing Settings as a Library and External Library, still can't seem to use it. I've also tried adding "import org.osflash.signals;" after each method but I

问题 How would one convert from 2x32bit uints to a Number and back (assume max value of 2^52)? I believe the following would theoretically work (passing around as ByteArray for clarity, but an Array could work as storage as well), But it doesn't because bitwise operators evidently force Number into 32 bits :\ (see: Binary math on Number objects limited to 32 bits?): public static function read64BitNumberFromBuffer(buffer:ByteArray):Number { var ch1:uint = buffer.readUnsignedInt(); var ch2:uint =

问题 I have looked far and wide but I can't find any resources on how to write to CSV files from flash AS3. I know that flash cannot write to it alone. I have used PHP before to write to a txt file but now I need to open a csv and insert/edit entries that are already in it. How can I do this? 回答1: There is no built in support for CSV, although it can be done manually: //dummy data var data:Array = []; for(var i:int = 0 ; i < 100 ; i++) data[i] = {a:Math.random() * 100,b:Math.random() * 100,c:Math
