问题 How do I properly draw one vector object onto a specific position of another in ActionScript, accounting for positioning, transparency, etc? My idea (as suggested e.g. here) was to use beginBitmapFill () and drawRect () to draw a bitmap copy (made using BitmapData.draw ()) of one MovieClip onto the . graphics property of the other MovieClip, but this proved more difficult than I thought, mainly for these reasons: Transparency is not preserved : where the source MovieClip is transparent, the

问题 I have this Player class which is a movieclip, I'm trying to set it's width and height from it and then make it add itself to the stage, But for some reason, no matter what I do, this.width returns 0 and setting the size only works from the parent class.. why is this happening? public class Player extends MovieClip { public var head:MovieClip = new Head_normal_front(); public function Player(stage:Stage){ this.addChild(head); this.width = 10; this.height = 10; stage.addChild(this); } } Thanks

问题 Can anyone explain this? what am I doing wrong? 回答1: Math.Round(x:Number) rounds x to the nearest integer value. In your case 28 is the nearest integer value for 28.499999999999996. So here the behavior is correct. What is weird is that 0.285 * 100 is not 28.5, but that is a consequence of the precision of the Number class in as3. Here is a little more information about this and a possible solution: Innacurate math results Also you can see this SO question: Very strange number operation issue

问题 I have some html text that I set into a TextField in flash. I want to highlight links ( either in a different colour, either just by using underline and make sure the link target is set to "_blank". I am really bad at RegEx. I found a handy expression on RegExr : </?\w+((\s+\w+(\s*=\s*(?:".*?"|'.*?'|[^'">\s]+))?)+\s*|\s*)/?> but I couldn't use it. What I will be dealing with is this: <a href="http://randomwebsite.web" /> I will need to do a String.replace() to get something like this: <u><a

问题 Isn't there some way to re-write the following code, such that I don't need a gigantic switch statement with every conceivable type? Also, if I can replace the switch statement with some way to dynamically create new controls, then I can make the code smaller, more direct, and don't have to anticipate the possibility of custom control types.

问题 As the title states, my user's on iOS and Android are reporting their save data has been deleted when I push an update to the respected storefronts. The game saves and restores data properly on application load and exit. I have not changed any save information locations or package names... Just mere bug fixes, build, push. Any clarification would be helpful, or proposed redundant data backup scheme's I should pursue to ensure the end-user experience is from henceforth not affected negatively.

问题 I have created a video player, but need to add a button that, when clicked, puts the video into full-screen viewing mode. I don't want to scale everything on the stage - just the video. I can't seem to find how to do this - I thought it would be easy. 回答1: See if this works: stage.displayState = StageDisplayState.FULL_SCREEN; videoPlayer.x = 0; videoPlayer.y = 0; //save the width and height in temp vars //for restoring them later. videoPlayer.width = stage.fullScreenWidth; videoPlayer.height

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I want to start Flash/Flex/ActionScript development and got lost with the technologies, documentation and tools available. Searches pointed me to Adobe FlexBuilder and Adobe Flash (Designer, CS3, CS4). Then, I found FlashDevelop, learned that Flex SDK and compilers are free. Also, you can make a complete Flash

问题 I'm trying to send array of data from Flash to PHP to sending e-mail. I'd like to do that because I must change the php page everytime my form site changes because of client's choice. My answer is, can I send an array of objects like this to php? var message:Array = new Array (); message.push ({field_name:"Name", value:"John Lennon"}); message.push ({field_name:"e-mail", value:"john@beat-less.com"}); message.push ({field_name:"Message", value:"Hello goodbye"}); so, PHP should recive a string

问题 After some search and reading the Graphics class document, I can't find a way to specify the line style of a line. I mean whether the line is a solid one or a dotted one. Could anybody help me? Thanks! 回答1: Well there is no Dashed or Dotted line in flex. However, you can create your own line or border: http://cookbooks.adobe.com/post_Creating_a_dashed_line_custom_border_with_dash_and-13286.html Try and enjoy! 回答2: You can't, well, not just by using Flex library classes anyway. You can do it
