Actionscript 3 :: Hit Testing On Many Objects Flash?
Nov 24, 2011
I am making a simulation that involves particles dynamically added to the stage (lots of circles). When these circles collide (which are actually movieclips) they need to rebound (momentum switched). I have no problem with the physics but do not know how to efficiently check for collisions. It boils down to being able to 1) Check if a particle is colliding and 2) Getting which other particle (object) is involved in the collision?
I would ideally like particles to be able to check for their own collisions and adjust their own momentum, not just some meaty Render() function running on every frame. How could this be done?

I have a new flash with several objects(classes) created in as3.They are called Ball1,Ball2,Ball3 and are of type Ball.I wish to be able to insert them into an array and have the array loop test them all against each other like eg. array[i].interact(array[i+1]) and so forthAdditional things I'ld like are:Making sure an object isnt tested against itself,removing objects from an array.sorting the array(if neccessary).adding new objects to the array

I'm trying to create a sort of tree diagram such that, if you click on one of the circles, its child circles spread outward with some degree of randomness from the original circle, connected by lines. I have this working, but now what I want to do is make sure that none of the circles collide with each other and none of the lines criss cross. You can see the screenshot for what is currently happening. My code is below. How do I change this code so that it checks for collisions and avoids them? I've read up on flash's hitTestObject command, but that only works in the context one object to another. I want to test for one object contacting any display object.
import com.greensock.TweenMax;
var sw = stage.stageWidth;
var sh = stage.stageHeight;
[Code].....

I'm having a serious problem with looping through an array. I'm trying to hitTestObject every MC in an array against every other MC in that array.The issue is that in my hitTestObject statement, if obviously looks at only 2 elements at a time.When 2 MC's touch, I set a property called "Touching" to true.The problem is these are moving MCs and at any given time only 2 out of 3 are touching.So what's happening is:The loop runs once testing Array[0] and Array[1].Say those are touching.It sets their "Touching" properties to true(thats what I want).THEN, it runs again testing Array[1] and Array[2], and finds that they are NOT overlapping.It this process it sets both of their "Touching" properties to false, EVEN THOUGH one of them may be overlapping a different array object.I want to individual set the "Touching" property for each array object.Right now these properties are getting overwritten even though 2 out of 3 objects are actually overlapping.[code]

Is there a method for testing when a shared object has finished loading?because as you can see i have a considerable amount of variables to load, and they don't always load in time.causing many glitches.
ActionScript Code:
wep=saves.data.wep;
backupwep=saves.data.backupwep;

I'm writing a general physics engine and I've come across the problem I've always had with flash. So far all my hittests in my physics engine have been calculated by using x/y coordinates and the 2 objects dimensions. This has worked fine for the objects so far because they have been very square-ish and do not rotated. How ever now I am trying to detect if 2 rotated objects are hitting. How can I do this ? I would really like to avoid using any .hitTest() functions.

I use this pattern to test for undefined and null values in ActionScript/Flex :
if(obj) {
execute()
}
Unfortunately, a ReferenceError is always thrown when I use the pattern to test for child objects :
if(obj.child) {
execute()
}
ReferenceError: Error #1069: Property child not found on obj and there is no default value.Why does testing for child objects with if statements throw a ReferenceError?

I basically need to scale an object up when the user rollsover the button which I have created dynamically already and I need to make sure the object is fully scaled up before I can allow the user to scale it back down again.Ive tried putting 2 tweens (x and yscale) into a function but not sure how to check if the tweens have finished. Im assuming if I check the function is complete it wont take into consideration the tweens may still be running.

Flash CS5.5 crashes when testing this movie using CTRL-ENTER a few times. Sometimes, a message warning that the Java Virtual Machine is running out of memory appears. I would like to know whether it is the FLA or my Flash installation that is corrupt.

I recently finally moved across to my Mac for all of my development work. The main problem I have come across is not being able to test any of my work in a SCORM test suite. The one I have on my PC is the ADL test suite which does not appear to be compatible with the mac, so does anyone know of a suite that is?

The app "XXXXXX" was not installed on the iPod "XXXXX's Ipod" because it is not compatible with this iPod.I've even tried it with a simple "Hello World!" app but I get the same error.I'm using Flash Pro Cs5.5 on a Windows PC.

I'm stuck! I've been surifng through the forum + several other forums for the last few days without getting closer to solving my problem.I've got 3 looping movieclips on the stage.Each of the MC consists of 3 frames with an image in each frame. When the user clicks on any of the MC, the MC stops and a certain image is loaded into a 'holder' on the stage. I've managed to do that by using this code:
onClipEvent (mouseDown) {
if (this.hitTest(_root._xmouse, _root._ymouse)) {
if (this._currentFrame == 1) {

The thing I've be struggeling with for ages now is the next step: When the user has clicked and stopped one of the movie clips she is supposed to move on and click and stop one of the other movieclips. Fine, but what I need to find out is which images/symbols that have been loaded into the different 'holders'
If holder1 contains a movieclip with the instance name 'pic1' and holder2 contains an image called 'pic2'a specific external movie will be loaded etc.
Is it possible to test the content of the holders/movie clip against each other? I hope there is, but with my limited knowledge of Actionscript I've not manage to find out how?

While testing the movie within Flash,the Test Movie window randomly goes blank, showing the stage color. The movie is still running, there's no error, it's just blank. When I resize the Test Movie window,everything reappears... Until a few seconds later, when it snaps back to blank... so I resize, it reappears, it disappears, I resize, it reappears, it disappears... over and over.Resizing even just one pixel is enough to get it to come back. Sometimes it happens every few seconds.
This might be related to another issue: If I Test Movie with the Bandwidth Profiler on, Flash CS4 doesn't resize the window correctly to fit my entire movie in it, resulting in a big blank space underneath the Bandwidth Profiler, and that same amount of space being cutoff the bottom of my movie. I haven't seen anything like this in 10yrs of Flash development. This is a Mac Pro, 8-core. The graphics card is ATI Radeon HD XT 2600. 6GB RAM. 10.5.3-10.5.7
The same FLA works without any issues on CS4/XP. The FLA saved to CS3 works without any issues on CS3/OSX and CS3/XP (same machine).I have all but given up on CS4 for OSX. Between the crappy framerates, the crashing, and not being able to TEST MOVIE, I just avoid CS4 on OSX and use CS3 on OSX or CS4 on XP.

Looking for some recommendations on tools that can be used independent of the source (that is just on the swf) to check for Frames Per Second, total size and how often the movie loops.

I have created a small flash project with 6 Scenes(two scenes contain flv clips 2 minutes each(1560 frames)). If I test each scene separately it runs perfectly, but when I try to run the whole movie it runs for 10 minutes "Exporting SWF Movie" and then stops without any errors or warning and without running project or creating swf file. I am using Adobe Flash Professional cs5.5.

I made a AS3 web site. Made my own classes and am using quite a lot of media in this site. At least 10 mp3s/page for 3 pages and one site with 20 short .flv videos. All data is being loaded with an external XML. I also use a lot of tweening from the TweenMax package. The final .swf is only 600 KB big.
When I export the site everything loads beautifully. But when I do like a lot of site changing - I counted that arround 30-35 page changes - make my flash player and Flash CS5 crash. It will crash also when I click through the pages slowly.

I am loading contents of a text file into a variable in my flash movie (this is a hybrid director/flash app - the director loads the contents of a text file into a variable in the flash movie). How would I test that variable to see if it is empty? I want to write a chunk of code so that if the variable has nothing in it, the movie jumps to a certain marker. Here is what I have so far:
Code:
if (variablename == "") {
gotoAndPlay ("marker2")
} else {
gotoAndPlay ("marker1")
}
Am I on the right track? The textfield that is the variable sits at the root level, and I am testing it from a movie clip, so should i make it _root.variablename?

I am working on a flash application on my local machine. It involves reading and writing to an xml file. I am facing a lot of security problems because of flash sandbox. In order to get around this I have installed php+apache to call an external file that writes to a file. I have created the crossdomain.xml and put it in the root of the web server on my local machine.
However, I can ONLY run the flash file in the flash program AND IT DOES WRITE TO A FILE. If I publish it as a html I still get the security error msg. Now another requirement of my program is as the user interacts with my flash application it changes an xml and the page should refresh to show the changes. But because I can't run my flash program as a html file I can't refresh the damn page! I'm half thinking of setting up a vm machine as a pretend server to get this damn thing working. Then I at least have the server + client model.

when I test my project in flash CS4, both the flash player and the authoring tool detect my keystrokes. Is there a way to make the authoring tool ignore key input while testing a movie, since I really only intend the key presses for the movie?
has anyone else found trace() to be much, much slower in CS4?
