ActionScript 3.0 :: Object Disappears When Returning To Frame?
Apr 22, 2012
I have, among many objects, a SimpleButton called nextBtn on the stage on the second frame. There's a function on that frame that does various things, one of which is adding a MouseEvent to that button. After moving to the next frame programatically and returning to the first frame the button is now gone from the stage. Because it seems to be gone, there's a null object reference error where the listener is added.
I've verified that:
- There are no other objects on the stage that share the same instance name
- This happens to MovieClips as well
- If I avoid adding the listener the second time via wrapping it in a if nextBtn != null statement, moving back another frame causes a button on that frame to disappear
I have a button on frame1 that when clicked, takes you to frame2. On that frame 2 there are two more buttons; one takes you back to frame 1 and the other takes you to frame 3. On frame three there is a button that takes you back to frame 1.
If you are on frame 2 and go back to frame 1, one of the buttons on frame one disappears. If you are on frame 3 and go back to frame 1 a different button disappears.[code]...
I'm having an issue with a button that exists on a frame in the timeline. I have 5 instances of the same button on this frame. When I first go to this frame, everything is fine. I then go to a different frame. When I give a gotoAndStop() command and return to the original frame with the 5 button instances, 1 of my five buttons is missing. I have no removeChild() commands or anything that would make this button dissappear. why this one button (out of 5 identical instances) would be gone upon returning to this frame?
I have a movie clip on stage which length is 600 frames. I put a actionscript 3 code "stop();)" at the end of movie. it stops when it reaches to 600 frames but it disappears from the stage as well. Which I don't want. It should stop animating but stay with last fram which has a welcome message.
Okay, so I have used this many times before but I cannot figure out how to fix this. This is what happened. after i open up any type of document like an actionscript 3.0 document or anything, if i draw with the paint brush as soon as i let go of the mouse button the line disappears. If i go into the timeline and click on the frame it shows up again, but if i draw again it disappears and i have to click on the frame to see it.

I have an object of a white cross on top of a mountain. I want my mouse to move over it and make it disappear and when my mouse moves away from it I want it to re-appear. So far I can make it disappear by moving my mouse over it, but then it will not re-appear. Here is the code I'm working on: CROSS1933_mc.addEventListener(MouseEvent.MOUSE_MOVE, mouseMOVE); // MOVE MOUSE OVER CROSS function mouseMOVE(event:MouseEvent):void { CROSS1933_mc.alpha = 0; } How do I make the Cross re-appear?
Would anyone happen to know how to change attributes like .z, .rotationZ, rotationY etc on a created MovieClip/Sprite or whatever. Because when I create a new mc or sprite and try to change these attributes the object just disappeares.
I am new to AS3 and need to gather data from an XML file, parse it and then return all the vars to be used globally. How do I return an object like in the code below?
Code: var dSession:Object = new Object(); function parseXMLData(incomingData:XML):Object
I am trying to switch my doctype to HTML5 to play around with some of the new stuff, but I am running into an issue with flash.
The following code works ONLY when the doctype is set to PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN". When I switch it to just HTML, it works in chrome, doesn't work at all in Firefox, and renders a small crappy looking thing in IE9.
<!DOCTYPE HTML> <!-- PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" --> <html> <head> </head>
I'm able to return django models that have only CharFields/Dates/Integers, but now I'm trying to return models that have ForeignKey properties and I'm getting this error in Flex in my NetStatusEvent.NET_STATUS onError event handler: m_info Object (@16491fe9) code "NetConnection.Call.Failed" description "HTTP: Status 500" details "[URL]" level "error"
Here are the models that matter in models.py: class RewardActBase(models.Model): user = models.ForeignKey(User) start_date = models.DateTimeField(blank=True, null=True) progress_value = models.IntegerField(default=0) [Code] .....
Then when I want to get retrieve these object via pyamf, this is the method I'm using, which is giving me the error I listed above.: @login_required def get_challenge_act(http_request, location_id): user = http_request.user c = ChallengeAct(); [Code] .....
The interesting thing is that if I change my get_challenge_act method to return a property of the ChallengeAct object, I don't get the error. So I can return properties or objects that belong to the ChallengeAct, but not the ChallengeAct itself. For example, the following code returns a Challenge object with no errors: return c.challenge So it appears that there is some problem returning a Django model with foreginkey models as properties?
I have built a XML decoder that places any supplied XML data into a object and spits it back to the callee.Everything is working so fine, the XML is being parsed, data going into its proper locations... however, when the script does its return, nothing is passed... just a object with no contents...
I'm using Flash CS5 proefessional and trying to do a demonstration. The demonstrationincludes a rope-like lanyard that is quite long and needs to bend at many many points. After successfully applying the bone tool to the object, I tried moving it with Free Transform.However, when I do so, the lanyard suddenly disappears, besides a couple tiny pieces. I didn't delete the previous layer, and I had unioned everything before breaking it apart again to apply the Bone tool.
I have a files that is loading and parsing a huge amount of data from a csv file and creating and plotting a graph using the data. All is well if I have the file loaded on the first frame of the movie. But if I pass in the URL by entering the file name in a text input field and clicking a button. The X and Y axis values disappear as do intermittent notes placed above the bar graph. I still see the x and y axis and it's hash marks and the bar graph (shapes) but all of the text is gone.
I am moving movieclips around my stage in relation to the users mouse location. All of my movieclips have the registration point placed in the default top left corner. As an object moves off the stage to the left it suddenly disappears when the registration point reaches the edge of the stage. I would like to see the whole object move off the screen instead of just disappearing when the left corner reaches the edge. I would move the registration point to the right side but I would like the movieclip to be able to move off all sides of the stage (top, bottom, left, right)
I'm using the native Flash StyleSheet Object to hold externally loaded CSS styles, and when I run the the getStyle("myStyle") function of the StyleSheet Object, it returns an Object in all cases, even when the style doesn't exist!
In cases where no style is found on the StyleSheet, the ASDocs say that the getStyle() function should return null. So if "notAStyle" is not a style on the StyleSheet, and I test[code]...
Everytime a clip is being started the line var so = SharedObject.getLocal('mysharedobject', '/'); creates new mysharedobject instead of returning the reference to the existing one. What might be the reason for this?
Can someone explain why the text of a dynamic text object disappears at runtime when rotated?It happened when I rotated a MovieClip object via actionscript that contained a dynamic text object. So, to test whether this happens all the time, I created a movie clip again with a dynamic text object in it, populated the dynamic text object with a single letter, and rotated it by hand and ran the movie - the letter disappeared.
LOL in a happy, rare accident, I discovered the answer myself. Page 432 of the Flash 8 Actionscript Bible says, "Aside from just allowing text to look the way you want it to look, embedded fonts actually enable your Textfield objects to do some things they wouldn't otherwise do. For example ... a TextField object that uses device fonts (nonembedded fonts) cannot be rotated nor can you change the alpha. But once you embed the font, you can do both of these things."
How: (for dynamic or input text objects) clicking the Embed button in the Property inspector.Note, this will increase the size of your swf. Just embedding the lowercase and uppercase letters from a-z of one font increased the swf filesize from 3-9KB.
I have 3 frames each with a movie clip called map_mc. Each different map_mc have different objects that call the CollisionDetect class. Heres whats happening. objects from frame 1 will start freaking out when I goto frame 2. How do I remove only the event listeners from objects only on frame 1?
I have been trying this.currentFrame but the problem is that all the objects are inside map_mc on the first frame so no matter what it will always be 1. On the other hand MovieClip(root).currentFrame will always give me the current frame but wont tell me what the objects frame is relative to the stage.What I want to do is have something to this effect:MovieClip(root).this.currentFrame would output that this object is on frame 1 and MovieClip(root).currentFrame will tell me that the stage is on frame 2 so I can remove the listeners accordingly.
I'm trying to trace the path of an object by using setPixel on the object's position every frame in a BitmapData/Bitmap pairing. These pixels aren't showing up normally and I suspect I have a fundamental misunderstanding of the BitmapData class. Here's what I'm doing:
public var contrailBase:BitmapData; public var contrail:Bitmap; private var contrailColor:uint;[code].....
Using this code, the red pixels don't show up. If I initialize contrailBase to 0xFF000000 instead then I get a black screen on which the red pixels DO draw, but I need the bitmap to be transparent except for the contrail. What am I doing wrong?
I need to know how you drag an object into another object and when the click is released it goes to another frame, and if you release not touching the other object the draggable object will go back to the place it started in
My question is, is it possible to rotate an object from frame x to frame y?I mean, let's say I want to move an arm. Instead of working frame by frame to make it move, is it possible to somehow make it rotate 90 degree from let's say frame 10 to frame 15?
Ok, so I made a custom class, but I did not want to add all the text to it through code (much easier to type it in flash on the frame). I name the instance aScoreBoard.
As my code runs, I need to call some of the functions that are part of the ScoreBoard class. As the code gets to this point, I try this line:
aScoreBoard.UpdateScores(passArray);
which will update the scores on the scoreboard. When that line in AS3 tries to execute, I get this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at Main/Main:ayEnd()[C:projectsDev_LearningLongJumpsrcMain.as:616] at Main/Main::ButtonAfterJump()[C:projectsDev_LearningLongJumpsrcMain.as:606]
Is there a way to do things this way? or will I have to go and do all the extra text entering in the code?
here what i have:- On stage, a clip (video_mc) that has 2 frames- frame one is a jpg preview of the FLV with a playBtn- playBtn leads to frame 2 where FLV Component (videoPlayer)plays a video (using FLV, not netStream)What i want to do:- I want to stop and rewind the FLV Component (videoPlayer)lying at frame 2 of video_mc from a button (retour_btn) thats onthe stage.Ive tryied this code to target the FLV to not avail:video_mc(currentFrame = 2).videoPlayer.stop();I assume im not that far, but cant figure it out.
I have an object present in frame 3 of the main timeline. When the object was present in frame 1 i could access it from an as3 code file. But when I am keeping the object in frame 3 of the timeline (Please note that the previous frames for that layer is blank). I am getting a null value for the object. if I try to use trace the object.Logically if I am in frame 3 i should be able to access it.
I have got a Swf file that contains only two frames, one has a timeline object called movie, the other doesn't. I place a trace(movie); statement in both the EnterFrame event listener and frame scripts on each frame and i found that the object movie is not available in EnterFrame event but can be accessed in the framescripts.[code]So I am just wondering when the timeline object is available during processing a frame and i can access the object? And from the output, it seems after the the SWF file being setup, there is no EnterFrame event dispatched for the very first frame, is that true?
But the plan is to make a "Drag and drop" Object that we are supposed to move around til the finish line.The problem is basically that I can't seem to find any decent ways of making this happen..When this "object" hits the other "object" (finish line) we move to the next frame.should be a simple/short line of code I think, from own experience.I have on my own exploring found similar problems without beeing able to fix it for my purpose:"One Object Hits Another It Goes To Another Frame."
