as3 performance

Original address: http://www.richbox.net/blog? P = 303 In as3, we can use getchildbyname to obtain a component, but note that the returned type is displayobject, so that once our component has some custom methods, it cannot be used. For example, if I have a ball class and ball has a move method, I can write it like this: VaR B: ball = new ball (); Addchild (B ); B. Move (); // No problem Getchildbyname ("B"). Move (); // an error is returned during co

Similarities and differences between onenterframe and onclipevent (enterframe) of as2 and as3 In the flashas manual, enterframe is interpreted as a frame entry._ MC. onenterframe {} indicates that an event is triggered when the video is played to the current frame. When I first started learning as, I naturally thought that if the current frame uses the stop statement, the video will stop playing and the onenterframe event will no longer be triggered.

Friends who are interested and have the conditions (installed the latest version of FlashPlayer8.5 and have a webcam) can first experience the FLEX2 I developed with the tip of the program:http://www.weni.cn/capture/ With the release of Flash8, the use of Flash8 bitmap processing new features to develop the application of the big-head sticker is more and more, the more prominent is Tencent's Qq-zone. However, using Flash8 's AS2 to generate pictures and provide users with less efficient downlo

As3 loading MP3 ID3 garbled solution most MP3 ID3 uses GBK/gb2312 character encoding. In As2, usedcodepage can be used to solve the problem, but in as3, even if usedcodepage is used, sound still uses utf8 encoding to read ID3 information when loading MP3 files, this makes the ID3 read by a large number of MP3 players garbled and cannot be displayed normally. This is a very unpleasant thing. The following co

data. uncompress () VaR Height: Int = (data. Length-4)/4)/width; // (Data. Length-4) ** remove the first four bytes, and the rest is the bitmap byte array ** // (Data. Length-4)/4) ** the length of each pixel is 4 bytes. Therefore, the total number of pixels is calculated by dividing it by 4 ** // (Data. Length-4)/4)/width ** remember, the height can be calculated as a rectangle ** After obtaining the width and height, restore the image:VaR BMI: bitmapdata = new bitmapdata (width, heig

Some time ago, someone mentioned in flashseer that the SWF file can be transmitted through socket, so that users cannot get the SWF file... at that time, there was no as3 decompilation, so I didn't care about program protection. with the popularization of decompilation programs, friends who don't want others to see the source code will be worried... The idea of transmitting SWF files through socket to avoid source code leakage (only applicable to

" is also processed as a common character.For example:Trace ("this is a book \ nkie". Replace (/bo + K. Kie/g, 'har '));Trace ("this is a book \ nkie ". replace (/bo + K. kie/GS, 'ha'); // here, \ n is considered as a common character Return Value:This is a bookKieThis is a ha X extended mode. In extended mode, the blank characters in the regular expression are ignored. For example, the effect of/C _ d/is equivalent to/C_D/ 5. Attributes of Regular ExpressionsSource can get the matching mode of

The Dictionary Class (Flash.utils.Dictionary) in AS3 is a new as class. The only difference between the dictionary class and object is that the Dictionary object can use non-string keys as key-value pairs. For example:var obj:object = new Object ();obj["name"] = 1; The key is the string "name"OBJ[1] = 2; Key is 1 (converted to string "1")Obj[new Object ()] = 3; The key is a new Object () and is transferred to the string "[Object Object]"for (var prop:

Long time no write AS3 program ... Mactan even a single XML read is not fast.Here's a good example of what Flex Biulder has just written:The code is as follows:package{ImportFlash.display.Sprite; Importflash.events.Event; ImportFlash.net.URLLoader; Importflash.net.URLRequest; Public classTestxmlextendsSprite {Private varLod:urlloader; Private varurl:string="D:/testas3/testx.xml"; Private varurlre:urlrequest; Private varAllxml:xml; Public functionTes

Cause: AS3 calls PHP and PHP returns an XML structure asynchronously. AS3 assigns some node values in the XML structure to an object and then passes the values to JS through interaction with JS.Debugging process:PS item is the xml returned by PHP:Var obj_info: Object = new Object ();Obj_info ["from"] = item... from;Obj_info ["context"] = item .. text; Trace ("UserMessage --> Message

In as2Var a: String = "";Trace (Number (a); // output: NaNTrace (isNaN (a); // output: trueIt indicates that variable a is not a number.In as3Var a: String = "";Trace (Number (a); // output: 0Trace (isNaN (Number (a); // output: falseIt indicates that variable a is a number.As2 and as3 are very different from each other. When the as2 algorithm is converted to as3, pay attention to this w

as 3 implements event passing, divided into three segments capture,target and bubble, where bubble is passed to the root of the tree. This mechanism is very classic and easy to use, unfortunately it only exists in the Displayobject object tree, other times can only be honest from one object directly to another object. this time I'll play an interesting. using the built-in mechanism of as 3 to make a more general bubbling framework is believed to be useful (at least for my project).

This section describes the data configuration. This data configuration is mainly used to convert mysql Data from a database to a java object and then to a data class of an as3 object. The configuration file is in xml format. Only one root node objects can be configured. Each sub-Node object represents a data class, and each sub-node field of the object represents an attribute of the Data class. Object: --- Name indicates the data class name, which m
