I'm having trouble setting up my object pool. I created a "BallPoll" custom class to handle the pooling logic. I first call fillPool() to add 20 Ball objects into my array. Then in my document class when I want to create a Ball, I check the pool array. It isn't working and I'm not sure why.

When is it a good idea to use an object pool in Flash? For example, is it a good/bad idea with bitmaps, MovieClips (with timeline animations inside of them), video, fonts?
View 1 RepliesI'm learning to use Object-pooling. I'm trying to see how to get objects from the start of the pool and shift all the objects at position i to i-1. I've had a look at Adobe's help file on the subject [URL] but there I'm confused.

Can anyone show an example of the object pool design pattern, as written with Actionscript 3.0?
View 1 RepliesI've been trying to figure out how Flash does its memory management regarding object declarations but haven't found anything that describes declarations themselves. [code]Basically I want a pool of declared variables that get instantiated only when a certain type is set. I'd have logic in other functions that figures out what the type is and then does certain things to it, but for now I just wanted to know what kind of memory management Flash does with something like this. Does it do nothing until I actually instantiate it (= new Object()) or will space be set aside once I simply declare it (someObj:Object)?
View 2 RepliesYou can hook into the creation of Flex 4 item renderers easily enough (through itemRenderer, or itemRendererFunction) allowing you to pull renderers from a custom object pool, but how would you put those renderers back into the pool?
I understand that layout virtualization does a form of object pooling, but I'd like a way to hook in to that. For example, when an itemRendererFunction has been assigned to a data group with a virtualized layout, item renderer construction is indeed deferred, but the instances are not re-used - I'd like to be able to intervene there, if possible.
But even in the case of normal virtualized renderers (where the instances are re-cycled) it would still be useful to be able to manage the pool manually. Pools could be shared between data groups, for example, to reduce the initial buffer required to populate each group.
Is there any way to know when Flex discards an item renderer instance? I have a sinking feeling that there is just no reliable way to tell - even though perhaps there should be.
I want trace every event on every object, there is way to do it?
View 2 RepliesI've been reading a lot about the benefits of Object Pooling. Found some "tutorials" online, all above my skill level. Can anyone please show me an extremely simple example of an Object Pool. What my game does is creates Ball objects when the user holds down the mouse, stops when user lifts up mouse. I need to store these Ball objects in an array(or Vector), and hit test them with other objects, removing them from the stage when the hit another object. I'd like to create a pool of say 20 of so, created once, and recycle them.

I have a website - [URL] - and on this website I have a pngfix. I also have a flash object. In IE6, which I am required to support, every image after the flash object is not included in the document.images that the png fix uses to loop through the images, and so the png fix doesn't get applied. Any ideas how I can get the rest of the images to appear in this list? (I am looking to replace the brightside group logo and it really shows with the new image)

View 1 RepliesI am calling one flash with transparent bg in an HTML page.. Now the HTML links which are below the flash area are not working. So how can I make them work. I knw though I am calling flash with transparent bg but still the object�s area is same.. n all the links which are there on the HTML page that comes under that area stops working as they no longer remain selectable. To have a clear picture of what I am tryin to do have a look at the following url : [URL]
this is just a sample file you can consider..Have a look at the register now button..It will be in HTML how can I make it work..as flash comes above it.
I'm working on an 8-user app that runs over a wi-fi network using an XML socket. All of the hardware is located inside a medium sized room in a school building.At the start of the app, each user can select 1 role from a pool of 8. However, the socket connection runs at less than realtime, probably because of latency from the wi-fi, so it's possible for two users to make the same selection at the same time. How would I prevent this?
View 1 RepliesHere is my pool game engine done in Box2dFlash.I would like to make this simulation more realistic as I received mixed opinion from pool experts.Here is my standard wall setting:
var leftWall = _sim.addBox({x:0.9, y:8.15, width: 0.6, height: 11.5, density: 0, fillAlpha: wallAlpha, lineAlpha: wallAlpha});
And of the ball:
_solidBall_7 = _sim.addCircle({x:ballPosX - (ballRadius * 5) - 0.8, y:ballPosY, radius:ballRadius, density: 0.1, linearDamping: 1, isBullet: true, restitution: 0.7, angularDamping: 5, skin: Solid_Bordo});
What other params I might try to improve the realistic movement of the pool game?
I'm creating a ball bouncing in 3d. My problem is that I have a square boundaries. top,bottom, front, back. I tried get the the distance ( of the sphere/radius) but went I * vx , vy , vz by 1 or -1. One of the position is - while the other two might by positive. I need pool ball physics with the boundary be a 3d sphere.

There is a Flex app with 7 main views. And there is a memory issue when navigating between views.All these views were in a ViewStack, but due to some involving 3D objects I assumed it was too much to have it all in the display list. I'm now clearing all children from the stack and adding/removing them when needed. This gave a small performance increase, but still becomes unresponsive with use. The strange thing is, with this and the original method, the CPU climbs with use but eventually levels out somewhere. Now I'm creating new instances of each screen when they are navigated to and setting the previous variable to null. Now it looks like CPU is spiking when the view is created, but leveling out to something much much lower than it was. This felt like progress, but now the available memory keeps climbing where it wasn't before....
My understanding was calling remove child or remove all children would mark the object for deletion when the garbage collector next ran. I can't see any other references to the instance. My code is along the lines of [code]I have a function for each button to add a new instance like the above.The only thing I can see and feel silly asking but need confirmation, is each view extends a class called "Screen", this class contains a singleton reference to some core components.[code]Would this trick the garbage collector into thinking it was still needed? General advice on clearing Objects from the memory pool would awesome!!! I've never needed to analyze the Flash Player in such depth.I think it's an error with sound drivers, removing all sound and shes purring like a kitten. Works on my machine fine with windows XP, but not on the touch pad the application is crashing on with windows 7 (unsure of the drivers looking into them now) Now I'm thinking its not the drivers, tried 3 different versions, all with no improvement. I did discover the sound was fading in and out with the TweenLite lib. Doesn't look like there are any memory leaks in TweenLite as it works fine on other machines. Just the use of volumeEasingFunction seems to consume increasing amounts of CPU until it freaks out. It is crappy hardware running windows 7, which doesn't help.
