问题 I'm creating a trivia game is Flash (AS3) with two different categories. The player can choose one category, or the other, or both categories together. In the code below I'm trying to merge the two xml files together into a new xml file if the person selects both categories. I'm getting an "Access of undefined property error for myLoader and myLoader2 and I don't know why. // start loading of questions public function xmlImport() { var myLoader:URLLoader = new URLLoader(); var myLoader2

问题 I have flash resizing it's container div by using external interface to call the javascript: function expandbottomNav() { document.getElementById('bottomNav').style.height = '400px'; } function shrinkbottomNav() { document.getElementById('bottomNav').style.height = '31px'; } Now this appears to work fine in every browser except chrome. For some reason after the div is shrunk back down to size, the flash player looks like it's frozen. It's actually not frozen because if you resize the window

问题 I'm building an Adobe AIR desktop app with Flash CS5 that makes a lot of use of bitmapdata, bytearrays and base64 strings. After a while the memory usage of the app doubles. Is it recommended to use system.gc() to free memory at that point or is that bad practice? Thanks. 回答1: system.gc is a debug only functionality in AIR and Flash player. I think the better thing is to recycle bitmapdata and other objects if you can to avoid gc, and if not call bitmapdata.dispose() and bitmapdata = null as

问题 I'm currently trying to make a dynamic menu via an array and a loop. So when someone clicks on the first item of the array, "menu_bag_mc" it will link to the content "menu_bag_mc_frame" (or some name that will be unique to this array) that is another movieclip that will load. Below is the code I have so far: //right here, i need to make a variable that I can put in the "addchild" so that //for every one of the list items clicked, it adds a movieclip child with //the same name (such as menu

问题 Its quite a big task but ill try to explain. I have an array with a list of 200 strings and I want to be able to randomly select one and add it to the stage using code. I have movieclips exported for actionscript with the same class name as the strings in the array. Also, if it is possible, would I be able to select the strings with predictability such as the first has a 0.7 chance the second a 0.1 etc. Here is what i have currently var nameList:Array=["Jimmy","Bob","Fred"] var instance

问题 I am just getting into object oriented programming, and I was wondering, is it okay to put some code on the timeline, like stop(); and mouseclick events for moving frames, or should all this be on separate files also? If they do belong in other files, how would I go about doing that? 回答1: MPO is that you should learn the tool as the tool. I think that the timeline is the very best part of Flash, and if you throw that away, you are making your life harder for no good reason. I think all tools

问题 I was having problems posting scores from a Flash CC AS3 game to a PHP page with SQL database . I was receiving ERROR #2101 messages in my output window. After a lot of time searching this problem I was advised to check if PHP was the problem. I have created a very simple Flash file, the code (I have replaced my actual site address below) is : import flash.events.MouseEvent; import flash.net.URLRequest; import flash.net.URLVariables; import flash.net.URLLoader; import flash.events.Event; var

问题 In As3, I use _loader.contentLoaderInfo.addEventListener(HTTPStatusEvent.HTTP_STATUS, onHttpStatus); to detect the httpstatus code of Loader . In the callback function the httpstatus code is 200 when the httpstatus code show in google chrome is exactly 304. 回答1: In reality, that should be the same thing because these status are reponses to your request sent by the web server, but with Flash while the requested file is in the cache, you will get always 200 HTTP status because in this case the
