ActionScript 3 :: Using Object Pool And Flash?
Jan 25, 2011When 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?

Flash :: Object Pool Not Working?
Dec 28, 2011I'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.

Sep 8, 2009I'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 RepliesActionscript 3 :: Implement An Object Pool For Flex Data/Item Renderers
Oct 6, 2010You 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.

Dec 24, 2011I'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.

ActionScript 3.0 :: Letting Each User Select Only 1 Item From A Pool?
Dec 4, 2011I'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 3 RepliesFlex :: Removing Flex DisplayObjects From View AND Memory Pool
Feb 15, 2011There 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.

View 1 RepliesActionscript 3 :: In Flash Does Extending An Object Use More Memory Even If The Object's Methods Aren't Used
Jul 20, 2011I am creating an object pool to cache some recyclable objects in memory at the outset of my application in order to avoid (as much as possible) the performance issues caused by GC running; if possible I'd like to minimize the memory my object pool reserves, so I'm attempting to pool generic forms of the objects (with no methods) and then casting the generic variants to more specific and complex object types which extend the generic form when I actually want them on the stage.
The trouble is that to do this requires the generic variant class to import/extend MovieClip (because the more complicated objects are themselves MovieClips and make use of DisplayObject methods)-- does simply importing and/or extending a class add to the memory an object takes up when instantiated even if it never uses methods from the inherited class? It makes sense that it would, and some light profiling seems to suggest that it does, but I'm not 100% certain. About how large should an 'empty' MovieClip instance be in bytes?
Flash - Serialize Circular Object Networks Using Write / Read Object
Oct 6, 2011I'm about to implement
public function writeExternal( output:IDataOutput ):void {...}
public function readExternal( input:IDataInput ):void {...}
to make a set of object serializable.
Although I'm pretty sure, that I implemented all correctly, readExternal(..) at a certain point complains about too few data left to read:
RangeError: Error #2006: The supplied index is out of bounds.
at flash.filesystem::FileStream/readObject()
I wonder, if I have a circular object network like
A = { left -> B, right -> B }
B = { father -> A }
And I call
writeObject( a )
Will Flex serialize the hole object network and each object once and only one?
I did this:
Declared type annotations like this: [RemoteClass(alias="model.MyClass")]
Implemented parameter-free constructors
Declared all classes using implements IExternalizable
SharedObject's send() method is guaranteed to send each object once and only once.
Additional infos:
Reading and writing a ByteArray
Using Remote Object Components
IExternalizable interface
ActionScript 3.0 :: Flash Player 10.1.85.3 - If The Object Is Not Found In The Dictionary Object, It Will Be Searched For In The Delegate Objects?
Oct 29, 2010I am encountering a problem in my app only when it is run in flash player 10.1.85.3. Some earlier player versions I have tried are working fine.From what I can tell it seems related to the following:
Quote:
from here: h[url].....
When searching for objects (not strings) in Dictionary objects using the 'in' operator, if the object is not found in the Dictionary object, it will be searched for in the delegate objects. With 10.1, the toString operator will be called on the Object if not found in the Dictionary. This can cause problems with Proxy objects who need to define the callProperty function or it will generate a RTE. ...what it means "it will be searched for in the delegate objects"?

Flash :: Using HitTestPoint With Stage Object To Create Object Boundaries
Dec 15, 2011I'm trying to create a boundary for a player object, controlled with arrow keys, in my game using the main stage's height and width. For example, one test point is at the top edge of the player object's bounding box so that when the player object's head touches the stage's top edge, the player can't move anymore to the north. The player object is manually instantiated to the center of the stage by using the Flash stage editor so it will start at the center before the program starts.The problem is that right at the start of the program, I can no longer move the player object up or down with the arrow keys but I can still move it left or right. The intention is to allow the player to move north until the player object's head touches the top edge of the main stage.[code]

Feb 23, 2012I am trying to do a apply a tween for the width property on a MovieClip Object but every time it changes the width and the position too, and I don't want that. I want to change the width going to one side without changing the x and y of the object.
I tried both of thes and they gave the same result.
var c:Tween = new Tween(left, "scaleX", Strong.easeOut, 1, 1.5,20,true);
var c:Tween = new Tween(left, "width", Strong.easeOut, 20, 200,20,true);
I think it is applying the transformation according to a center of the movie clip. but I don't know how it can be changed.

Flash - Slowly Rotate An Object Towards Another Object?
Jan 27, 2010I have an object that points in the direction of another object (i.e. it rotates to the direction that the second objects x and y coordinates are at) below is the code I use.
var distx = target.x - x;
var disty = target.y - y;
var angle:Number = Math.atan2(disty, distx);
[code]....
as you can see. Not only does it rotate towards the target object, but it also moves towards it too. When I play the movie, the object instantly points to the targeted object and moves towards it. I would like for it to slowly turn towards the object instead of instantly turning towards it.

View 1 RepliesFlash 10 :: An Object That Orbits Another Object
Aug 11, 2010I have been trying to build a simple shooter game in which the player is moving forward constantly (to simulate flying), but can turn left or right to avoid objects. What I want to do is to have the airplane fixed in place so that when the player presses the keys to turn, the rest of the objects on the screen rotate around the player.[code]
The problem is that the object seems to jump back and forth 180 degrees constantly. The object moves at a good speed around the player, in a full circle, but I can't for the life of me figure out why the object is jumping back and forth.Just to break down the code: given the fixed position of the player and the position of the object, the distance between the two is calculated as the radius. The x and y difference between the two is then used to figure out the angle in radians that the two points make. The angle is added to by a set increment, multiplied by 1 or -1 (xSp) to give it a direction. Given the increment, the new angle can then be used to figure out the adjusted position of the object using Math.sin and Math.cos.
