: Mask is a hexadecimal value that specifies the bit of the argb color to consider. Use The bitwise AND operator combines the color value with the hexadecimal value. Color is a hexadecimal value that specifies the value to be matched (if findColorSet true) Or NoMatch (if findColorSet false. Findcolor if this value is set trueReturns the range of color values in the image. If this value is set false, The returned image does not contain the color range.

In AS2, you can add parameters to the end of flash, for example, demo.swf? U1 = good u2 = bad In flash, u1 and u2 are the root variables by default. You can use _ root. u1 and _ root. u2 to obtain the value. But in as3. To use the parameters attribute of the flash. display. loaderInfo class, a parameter object is returned. Usage: For example, defining var param: Object = root. loaderInfo. parameters in the document class; If the value of u1 is obtain

user finishes playing a game, the user needs to return the score to js and then the JS will pass the score to the background through ajax. Of course, the score can be written directly in the flash code like in the white community, however, other web pages also need to get the score and compare it with the score of the current user's friend (you do not need to request the friend data of this game from the server, and you have already requested the score once when you enter the page, the data tha

Reflection refers to how a program obtains class information during runtime, such as dynamically creating class instances and methods. See http://bbs.9ria.com/thread-133293-1-1.htmlTo sum up the usage of as3 reflection, there are four functions:Flash. system. ApplicationDomain. getDefinition (linkName: String): Class; // The Link name of a component in the flashcs component library.Flash. utils. getDefinitionByName (name: String): Object; // return Cl

After searching a lot of information on the Internet, I finally started programming.Flash remoting with as3 by: Jorge Solis this article is good. I decided to start from it, and sourcecode is very suitable for someone who has no experience with flash.When I did the first exercise loading/saving data using amfphp, I encountered two problems: 1. Flash is created based on the example, and compilation fails.Source: 34 rows, trace ("there was a problem:"

The Security Sandbox of as3 is really helpless. This article is only used to solve a specific problem, that is, the SWF file on server a accesses files on server B through HTTP, in this case, even if allowdomain is set on server B. XML does not help. The files loaded on server B are excluded from the required allowdomain. security. allowdomain ("*") can eliminate the Security Sandbox (Note: Only SWF files can be set at this time, and images cannot be

In. net, the implementation can be achieved by means of polymorphism, but there is no polymorphism in as3. How can this problem be achieved? Sban writes an example to demonstrate the usage of namespace and the implementation and call of multi-state functions. Here, you can view the demo and source code. Sban is located in chaoyangmen, Beijing.

The Flash Optimization Efficiency is quite high. It seems that the efficiency of moving all bitmaps directly in the same Sprite is also good. This method is quite easy to use. I have tried a variety of direct bitmap operations. it seems that the efficiency is not as high as moving the entire Sprite.The less efficiency the flash layer moves on the interface, the higher the efficiency. That is to say, the efficiency of moving 5 bitmaps with for is much lower than moving 5 bitmaps directly in one S

1. Draw a drawing in as3. the first drawing will be overwritten by the later drawing.2. Draw an irregular image and connect it with a line. To fill it with a line, you only need to set the fill color.For example, draw a trapezoid with a gray border.VaR ladder_draw: SPRITE = new sprite ();VaR G: Graphics = ladder_draw.graphics;G. linestyle (1, 0xff0000 );G. beginfill (N );G. moveTo (100,100 );G. lineto (143,100 );G. lineto (130,120 );G. lineto (110,120

In as3, you can define other classes outside the package of a class and reference the package class in this class: Package com. Custom. utils{Public class tfunction{Public var minus: function;Public static const M: Int = 10;Public const N: Int = 20;Public Function tfunction (){VaR test1: test1 = new test1 ();VaR Test2: Test2 = new Test2 ();}Public var alert: function = function (M: int, N: INT): void{Trace ("tfunction is create:" + (m + n ));}Public F

Generate a form mainly composed of ComboBox component groups,Copy codeThe Code is as follows: package myfirst {Import flash. display.

Let's take a look at the summary in the as3 game programming, which is very classic. 1. Frame Rate event Motion It is very easy to change their position on the screen by setting the coordinates of x and y in the video clip. IfWe want to make this video clip move and set a specific speed for it, then we need to useEnter_frame event. For example, you can draw any image on the stage and convert it into a video clip,The class name is hero. Next, we use a

If you do not consider the security factor (anyone can connect FluorineFx for video recording without logon authentication), the server does not need to write a line of code, you only need to create a subdirectory under the apps directory as an application, and configure the rtmp Channel in the services-config.xml. The following as3 code of the flash client is modified from the official Flash AS2 example of FluorineFx (of course, there are many optim

Do I need to set all attributes to NULL for as3 object destruction? Chuan No Chuan Only external references are required. Chuan However, to prevent other Members from accidentally making a property externally referenced, it is best to return null. Coffee in the afternoon (8548439) 14:09:05 Chuan For example, some colleagues add a public method to your class to expose your private attributes and reference them... If you do not set null, the entir

Recently, I have watched a lot of projects at home.ArticleThey all say that robotlegs's as3-signal is four times more efficient than Adobe's official events. I wrote the following test with suspicion. It mainly tests when adding events and broadcasting events. First test Code : // Number of tests var forcount: Int = 9999; // Number of test changes var tmpnum: Int = 0; // The dynamic generation method is used to listen to VaR funobj: Object = {}; for

I used to think that I added a listening event to an object and then removed it. Then, his event will not be executed. In fact, this is an error! As3 is not Js. Its display, storage, and time listening are independent. It will not be deleted because you have deleted one of them! If the addeventlistener of this object is not a function or method, removeeventlistener is required! We need to understand that addchild is not equal to attachmovie, but it

be multiple references, so you can reference the function through variables.// Reference a function with the variable funcVaR FUNC: function = tracemsg;// Call a function through referenceFunc ();// Define a functionFunction tracemsg (): void{Trace ("this is function ");}The code above is simplified:// Define variables and reference functionsVaR FUNC: function = function (): void{Trace ("this is function ");}// Call a functionFunc ();The code first defines the func variable of the function type

Implemented a simple as3 MVC Framework, hoping to help you! Project address: https://code.google.com/p/m-mvc/ Users who need it can download SWC, SRC, and examples. This framework mainly controls message transmission through icationicationbus, which weakens the coupling between modules! Some simple instructions: Basedataproxy is responsible for data request and sending operations with the server Basecontoller is responsible for business logic pr

Previously, the flash as3 client was used to compress and upload images.CodeI haven't written the as code for a long time. I feel like I was born, but I had to write it myself after three afternoons. I thought a Flash Developer was here, but I didn't come, I have promised the end of the month by the Sales Department. The specific code is not described in detail. It is relatively simple, but it is a little ugly because it is difficult to calculate the
