Should I create a flash file for each screen size?

阅读更多关于 Should I create a flash file for each screen size?

问题 I created a swf file for one my clients using a screen size of 1024px x 768px (4:3 ratio), now my client wants to re-use the video in a bigger screen (TV) that still uses a 4:3 ratio but the screen size is considerably bigger (I do not have the exact size yet). Do I need to recreate the flash file using images that fit the new screen size, or the fact that they both use a 4:3 aspect ratio means that the image quality will not suffer? 回答1: It depends on what your SWF contains. If it's a video,

AS3 - Access MovieClip from stage within a class

阅读更多关于 AS3 - Access MovieClip from stage within a class

问题 I have been stuck on this for a long time and have looked at past questions on here about this similar issue such as this post: How do I access a movieClip on the stage using as3 class?. I use the constructor to listen for the ADDED_TO_STAGE event, and then initiate the main function to set up the eventListeners from the ADDED_TO_STAGE handler. Within the same handler I also try to get a MovieClip from the stage using the following code: player = stage.getChildByName("player") as MovieClip;

NOR型flash与NAND型flash的区别

阅读更多关于 NOR型flash与NAND型flash的区别

转自http://jinren1010.spaces.eepw.com.cn/articles/article/item/15556 　　（1）闪存芯片读写的基本单位不同应用程序对NOR芯片操作以“ 字 ”为基本单位。为了方便对大容量NOR闪存的管理，通常将NOR闪存分成大小为128KB或者64KB的逻辑块，有时候块内还分成扇区。读写时需要同时指定逻辑块号和块内偏移。应用程序对NAND芯片操作是以“块”为基本单位。NAND闪存的块比较小，一般是8KB，然后每块又分成页，页的大小一般是512字节。要修改NAND芯片中一个字节，必须重写整个数据块。（2）NOR闪存是随机存储介质，用于数据量较小的场合；NAND闪存是连续存储介质，适合存放大的数据。（3）由于NOR地址线和数据线分开，所以NOR芯片可以像SRAM一样连在数据线上。NOR芯片的使用也类似于通常的内存芯片，它的传输效率很高，可执行程序可以在芯片内执行( XI P, eXecute In Place)，这样应用程序可以直接在flash闪存内运行，不必再把代码读到系统RAM中。由于NOR的这个特点，嵌入式系统中经常将NOR芯片做启动芯片使用。而NAND共用地址和数据总线，需要额外联结一些控制的输入输出，所以直接将NAND芯片做启动芯片比较难。（4）NAND闪存芯片因为共用地址和数据总线的原因

What is the null-object error with this AS3 code for loading external swf?

问题 I am getting a null object error when I add the mouse event listener for the log in button. (Look at the comments in the constructor) I am using Flash CS6, and objects such as logInbutton and screen_log_in are instance names from the .fla file. This here is the .as file. Error I get is: TypeError: Error #1009: Cannot access a property or method of a null object reference. at actions::indexPage() My AS3 code: package actions { import flash.display.MovieClip; import flash.events.Event; import

How do I select a certain node in a tree in flex?

阅读更多关于 How do I select a certain node in a tree in flex?

问题 I'm trying to get properties for one single node such as the name I've set for it or something. How can I go by just selecting this one node? I can do it with an event e.currentTarget.selectedItem.@name; But I need to grab it without the event, how can I go by doing this? 回答1: it's better to get data from your data provider for xmlTree, because it's a XML/XMLList you can always use construction like myxml.nodename[0].@attribute 来源： https://stackoverflow.com/questions/4796462/how-do-i-select-a

recombine split TCP packet with flash sockets

阅读更多关于 recombine split TCP packet with flash sockets

问题 I have a program in c++ that sends a socket of 23723 bytes to a flash player in one "shot". The flash player sometimes receives two packets of size 17520 and 6203, and other times it receives a single packet of 23723. EDIT: There does not seem to be a way to obtain the total number of bytes associated with the send data from flash. This would make it very difficult to build a loop to reconstruct the "broken" packet. I thought TCP was supposed to correctly recombine the packets and I am having

AS3: Copying a Loader from one object to another

阅读更多关于 AS3: Copying a Loader from one object to another

问题 I have two classes, call them A and B. They both contain a Loader object. In class A I load content into the Loader object. public class A { var loader:Loader; public function A():void { loader = new Loader(); this.addChild(loader); loader.load(...); } } public class B() { var loader:Loader; public function B():void { loader = new Loader(); this.addChild(loader); } } I need to now assign A's Loader to B's Loader (after the load is complete). In some other class I have an instance of A and B.

Generating individual SWF's with classes from a fla with a large library

阅读更多关于 Generating individual SWF's with classes from a fla with a large library

问题 I have a series of large fla files that were being published into swc's and then used directly in an flash project. Probably a total of 1000+ objects. As the number grows the final compiled swf is getting quite large so I want to download individual swf's of each object only as needed. I then need to be able to access and clone the object via classname from the final AS project. The issue is the only way I have found to export each one is to 1) copy and paste it into a new fla file 2) double
