问题 Consider the following code: var combined:Number = Number(4294967296) | Number(2403025069); var testLimit:Number = 6697992365; trace("Combined is:", combined, "should be", testLimit); Output is: Combined is: -1891942227 should be 6697992365 Why?! I thought Number datatypes can hold 64 bit integers (okay- really 52-bit, but the numbers above are nowhere near that limit) 回答1: From the documentation: | bitwise OR Operator Converts expression1 and expression2 to 32-bit unsigned integers , and

I want to set it visible so i put in my code: Apple.visible =true; but it says that Apple is not defined, probably because it doesn't refeers to the stage one... how can I "import" it in my class? 回答1: Try something like: DisplayObjectContainer(stage.getChildAt(0)).getChildByName("Apple").visible = true; where stage.getChildAt(0) is "Main Timeline" movie, that contains all inner objects. 来源： https://stackoverflow

问题 Hopefully you will excuse me if this is a simple/silly question. I started learning action script about 6 days ago and already working on a small project :D Anyways, there is a property that changes occasionally to reflect the name of a level in a game (object._I._M.text). It could take a minute to change, or a max of two minutes, depending on how fast all players are able to finish the level. I want to be able to listen for the change in this property to fire off another function. I have

问题 I'm trying to make games for iOS and Android. How do I save data to the gadget, and also how do I load it? The data that I want to save to the user device is basically just a bunch of strings.

The attributes you write/read can be of any type (String, Array, Number, Boolean, XML, ...). Basic example: var scores : Array = new Array(10, 20, 30); var my_so : SharedObject =

问题 I know singleton class is not supporting in Flex.Because it does not access private constructor. But i want to make a class is singleton class. Please anyone can explain with example. Thanks, Ravi 回答1: A singleton is a class of which only one instance will be created. This instance will be shared by all other code in the program. A singleton in the strictest sense is not supported in ActionScript because a constructor cannot be marked private . Consequently, additional instances of the class

问题 I need to keep a NativeWindow I am creating on top of the main window of the application. Currently I am using alwaysInFront = true, which is not limited to the windows in the application. I can successfully synchronize the minimize/restore/move/resize actions, so the top window behaves appropriately in those cases. Even though using this option has the drawback that if I alt-tab to other application the window goes on top of the other application. Because of the above I am trying to get it

问题 is it possible to make a Flex-application to only run from my domain? So a user can't copy the .swf and start it locally. 回答1: In a lot of cases this won't work because of the security model associated with the crossdomain.xml. http://www.adobe.com/devnet/articles/crossdomain_policy_file_spec.html Say for example, I have a flex app that has a service call and login to my backend database (perhaps PHP and mysql). Unless I explicitly enable it in crossdomain.xml policy file the app will not be
