My understanding is that calling clear() on a sprite object will wipe the screen clear of previous drawings for the next draw. But my code below renders nothing to the screen when there is a clear() called.
Code:
var sp:Sprite = new Sprite();
addChild(sp);
var g:Graphics = sp.graphics;

deleting, killing objects and functions. There seem to be a few different ways to achieve to completely get rid of unwanted objects and functions(which are in turn objects as well, no?)
Just to refresh:
objects:
Code:
object = undefined // does the job
object = null // does the job
exception: if the object is referenced anywhere else in the application, the object is still in memory, unless the object's reference is killed as above. also: if you attempt to try cleaning up and object , which has objects itself, (e.g. object.subObject = new Object()), then those subObjects are still alive.
To properly clean up the object with subObjects, the subObjects have to be killed off seperately.

Does anyone know if we have to specifically remove event listeners that are added in a custom class that *only* listen to events dispatched from within the very same same class?
For instance, if I have a parent class that instantiates a child class that builds a simple UI which contains a few buttons that are only listened for in that child class, do I have to worry about removing them before removing the child from the display list & setting to null (on the parent-level)?
I'm working on a game whose background has many layers that each scroll at different speeds.
Inside each layer I have a Sprite, I've started using graphics.beginBitmapFill, but what I've found is that the graphics.clear() function doesn't actually clear the contents set by the previous call to graphics.begin.BitmapFill. Each frame, I adjust the matrix to shift the layer as needed. Then, I call graphics.clear() and graphics.beginBitmapFill() with the adjusted matrix. Since my layers have alphas in the bitmap, I can see the contents that was drawn the previous frame.
I wrote an application in flash AS3, and when I trace from flash the total memory usage of the total application is only about 9MB, But at the same time Task Manager Shows the memory usage as 110MB. Around 100MB difference.Flash Trace Method System.totalMemory difference of the Trace from the Beginning of the application to end of the application.

doesnt clear the line when mc1 moved ? How solve tihs problem?
I created a class, extended the sprite class, and now in the constructor I am trying to set the Sprite's width and height properties which are inherited from the DisplayObject. However, after I set this.width and this.height, and print the values, I get 0 for both.
What the heck is going on? When I view the livedocs I see that DisplayObject has width and height listed as public properties. I have been able to instantiate a Sprite directly, and set the width and height after it's been instantiated, so I don't get it.
package {
import flash.display.*;
public class ScrollBar extends Sprite {[code].....
I've got a sprite which I want to temporarily hide... But changing the .visible property doesn't do what I expect. The code looks roughly like this:

I'm doing a simple rotation on a sprite but there's a weird behavior where the sprite does not rotate around it's top left. I think I'm rotating along the top left of the test class instead of the sprite child. I would like to rotate the rectangle around it's top left corner (kinda like a clock hand). The code is pretty short so I'll let the code + pictures explain my problem:
package
{
import flash.display.Sprite;

I've read a lot of stuff about rotating around a fixed point, I've tried doing it with movieclips instead of sprites, I even copy pasted a tutorial on rotation and nothing works.

Then the numericStepper is drawn as if it is squished to 20% its normal height. If I pre-set mySprite width and height before adding the numericstepper, the trace output is 0,0 after adding it and it is not displayed at all. Is there some way I can make the sprite only adjust to correctly fit the numericStepper OR resize it afterwards without distorting the numericStepper component?
Both of sprite.width and sprite.scaleX can be used for scale a sprite. Is possible sprite.scaleX depends on screen size?

Everytime I google this question I see confusing information about masks and blends, none of which seems to directly apply to what I think should be an easy thing... There are three Sprites involved here...the lowest layer sprite is pretty much a background. I want to overlay a translucent Sprite on top of the background and then I want the third, top-most Sprite to act as a hole, so that the area inside the third Sprite is completely transparent, so that the background sprite is completely visible. How would I go about doing this dynamically (i.e. dynamically drawing the masking sprite and hole using the Actionscript graphics calls)?

View 9 RepliesI'm looking at finding a way of recording the amount of times a swf is loaded or a button pressed with the aim of giving a client feedback about how their product is used.Basically I am creating a touch screen app for a client which will contain a couple of hundred images and the client would like to keep track of which images are loaded in and how many times.
I looked at Mochibot which seems good however I don't think this app I am building will be connected to the Internet. So that's not a viable option. So is it possible to output something locally? Which will get added too every time the app is used. Even if the computer and app are restarted?
Currently when I load my presentation that I have just recently created and testing I'm getting a HUGE spike in my cpu usage.
I'm running an i5 2.4, and it's nearly taking up 100%, a friend of mine is running a core 2 duo and it's taking up 100% of the cores.
What is a proper way to optimize for these occurances? I don't have any preloaders up and running yet.

I'm user of relatively weak computer (pentium IV 3.0 with hyper-threadingiem) but with a bit newer graphic card - asus radeon HD4650I'm not big new games fun, I'm useing my hardware most to internet access so I would rather not to buy new computer in the near future. But also I would like to have possibility to watch flash movies fluently on full screen (eg. youtube, video streeming). Unfortunatelly, till now, it was pretty weak. I got hope that afther new flash release (lately), which should use computing power of graphic card and making CPU work lighter.
Unfortunatelly, afther flash update (10.1) I haven't noticed any changes - everything work in the same way (not fluently) as at old flash. CPU usage is still ca.100% and GPU usage is 0% (I can see it in control panel) What is wrong? Is it this version of flash what should use GPU or it is not yet? Maybe I should configure something more? Or is it possible that I made something wrong? I've tried few times, made lots of work and combinations (instaling and reinstaling different versions of flashs, graphic card drivers, browsers changing etc) and still nothing.
I have a question concerning CPU usage for games. What do people consider as an average or 'acceptable' amount of cpu usage for a game I've created a few different games, some which are more database driven have a very low cpu usage and small size.. others I've seen go up to 80% cpu usage..
I do try to keep a careful eye on this (I mean 80% of one core, of which I have 8.. I'm not sure how this will reflect on a single core/processor machine) but it does really concern me because as soon as I add an 'enterframe' function, spin something around or create a fair size animation it piles on the intensity to the cpu.. are there any professional tips anybody could offer me please ? I really want to make the web a better place for others by not overloading their computers
Is there some way to get the cpu usage in flash or adobe AIR?
I'm using ActionScript 3.0 and flash CS5.

Large flv (920 x460), with alpha channel (transparent background), Max data rate:300kbs,
codec : On2 VP6 encode alpha channel, framerate : same as source.
Using progressive download
Video plays in a flvplayback instance nested in a swf that is loaded and added to the stage by an other swf.
Embed in the html page with swfobject, wmode = opaque.
