I'm building an air app which will run on iPads. For the touch interaction I'm using just MouseEvents handlers (MOUSE_DOWN, MOUSE_MOVE, MOUSE_OUT, MOUSE_UP) because my app don't need multitouch, now I'm wondering if there is any difference in execution speed, should I use the equivalent touch events or the mouse events are faster?
View 2 Repliesthis is what i'm trying to accomplish; With a click on a movieclip (cannon_mc)a shot is being fired (ball_mc)
The longer mouse is down, the speed of wich the ball is fired with should increase.My question to you is;
What is the most efficient way to accomplish this? With a timer or something like this;

Is it possible to change the speed of execution of a movieClip? Maybe the frame rate?
View 6 RepliesI was wondering, because people do suggest this, but i've never explicitly had it verified:does the flash cs4 compiler actually generate a SWF file, that is more optimized and faster, than the flash cs3 compiler?and what about other compilers? custom as3 compilers, are there faster ones?I don't mean the time it takes to compile the .fla, but the speed of the SWF file.
View 1 RepliesI working on a game project in Flash AS3. I need to pass data from one class (Game) to other class objects (Ships) on EnterFrame and performance is starting to be a issue. I was wondering is there a difference in performance between calling to the Ship a direct function or dispatching an event which the Ship can listen.
another question is where should I put the enterframe function. Is it better to use only one enterframe function and call the methods dispatch events from there, or it will be wiser to put the enterframe in the different objects (Ships)? note: some Ships are inactive most of the time.

I am working on this cd-rom and have just reached testing stage for part 1 (of 5). There are lots of interactive activities, video and animations. For the activities, I dont know if I am just too tired but there seems to be items which are visible on my .swf on my computer that sometimes are visible and sometimes are not visible on the cd-rom, also in testing yesterday there sere some activities that seemed to not be working correctly (Althought they perform fine on the desktop version, on a reset of the cd-rom they then seemed to work. Is there anything that I need to take into account for the code being read off a CD to make it more bullet proof? I am stressing out a bit at the Unknown factor- I cannot continue to produce this resource if I cannot guarantee how it will perform in real life?
View 5 Repliesalmost every single one of my classes, starts with the same method. An event listener in the constructor for EVENT_ADDED_TO_STAGE. Then i do all my actual intialising in a beginclass function that listener runs.I've not generally been removing these listeners though. i never thought it would make a difference since i'm only adding these objects once, but i wonder if there's a performance element. it could be for example, that all of these listeners add an extra check each, ehenever any object is added to the display list.

I'm wondering if anyone has experience with if there is a big difference in performance in ActionScript 3 between keeping a class with only public static functions, and utilizing those functions often (as in a frame event at 30fps), and in turning the class into a "normal" class of which I instead make an instance and call the functions via the instance instead.

View 3 RepliesI have just finished the development of version 1 of my application using Flash CS4. It's almost completely AS3 code with a SQL backend. For the next version I want to look at adding TouchEvents for a mobile version of the application. But I'm confused as to what I need to add to my development software in order to develop apps that use touch. Do I just need to install the Flash 10.1 player beta in order to get access to classes such as "flash.events.TouchEvent" or do I need to upgrade to Flash CS5?
View 1 Repliesi've always seen people using "var" declarations in their code and i never knew what the point of it was, but then the other day i read about how they're faster for the computer to access in one of the tutorials (the "speed tips" part in a section of the "scripting 3D in flash" tutorial by senocular, [URL] ), and i altered a bit of code of mine that had a lot of calls from variables in arrays, assigning those variables to local variables, and the slowdown that the code caused before virtually disapeared! everyone probably already knows this, but i'm still somewhat of a newb to programming, so it came as quite a shock to me i had no idea that variable calls could slow down the computer so much, i figured that the time they take to execute is nothing compared to the time it takes to do things like math functions and stuff anyone got any other "common sense" tips on how to make faster code, that a newb like me may not know about?

I'm devloping some library classes for flocking/steering behaviours on large numbers of objects (2000+). I'm finding that at < 500 instances, performance is reasonable. As the numbers increase, framerate bogs down.
I've seen remarkable performance with libraries such as Flint or Box2D with ridiculous #'s of particles / objects, so it should be possible to optimize / refactor my code to be a bit better.
I'm aware of the basic optimizations, such as bitwise operations and optimized for loops. Are there any more fundamental approaches I should be considering? For example, currently each instance is a vector-based MovieClip. Would working with BitmapData be more efficient?
Will I take a big hit in performance using nested ViewStacks? Should I strive to handle all navigation in one ViewStack and push children manually or will the affected performance be negligible?
eg.
<viewstack>
<tabnavigator />
<tabnavigator />
<tabnavigator />
</viewstack>
We have a medium size Flex 3.6 application that contains around 20 different page views (managed via a single lazy ViewStack) each having multiple components. Most use custom renderers.All model data is loaded at startup and changes to model instances are communicated via binding and/or collection change events.Once the user has viewed each page at least once, all page views are instantiated and happily listen to update events.Which in effect means that each time a model instance changes, all interested views receive that event and compute derived data or trigger item-renderers.I have tested and confirmed this behaviour in a proof-of-concept application. Even when setting a list to being invisible, it still listens to collection change events and invalidates any renderer affected.What would you do?
View 1 RepliesI want to add an animated .gif file to my movie. So I created a new symbol and then imported the .gif file to the stage. This created the symbol containing the animated .gif.I dragged the symbol onto the scene where I want it. However, the animation seems to play at a different speed (fps) than normal. So I changed the fps of the symbol (at bottom of Timeline where it says "fps"). But for some reason this changes the fps of the rest of the entire movie.

View 2 RepliesI have a movie clip on my scene which has a speed applied to it making it move across the screen. This is duplicated when it reaches the other end of the screen.On my scene I have some action script which is acting as a timer. After a set time I want it to increase the speed of the movie clips, making the game become "harder". I seem to be able to manipulate the alpha of my movie clips but can't seem to trigger the speed increase.If i use a setInterval it seems to trigger the speed increase but it does it each time the movie clip is duplicated (so the delay resets, it does not change once and apply throughout)However, where I am changing the alpha I cannot seem to change the speed.

My code is correct, the code compiles (as you can see), it works fine in safari, but firefox 3.6 it up - it does NOT happen in 3.5.8!
I now have working code that creates a mask of about 2,700 children on a 650 by 450 image using a container to hold all the children's MCs.
Can anyone provide any help as to how I can access these children at once with a MouseEvent so that I could for instance change the alpha value of a child shape when the user rolls over it with their mouse.
I have a flash AS3 doc and some classes that I created. On one of the classes, it creats a sprite that may have a scroll bar, (which i also made - not the UIScrollBar component). This uses the MOUSE_DOWN event for scrolling.
On some other classes, there are some objects that use the MOUSE_OVER event.
The problem I have, is that if you click and hold the mouse button to begin scrolling, then move the cursor outside of this Movie Clip onto another with the MOUSE_OVER event, then that event will still fire. Also, if you MOUSE_UP and you are outside the Movie Clip (with the scrollbar) then the MOUSE_UP event does NOT fire, and the scrolling is "locked" on until you click inside that moive clip.
How can I prevent mouse events on objects from firing when the MOUSE_DOWN event is firing for scrolling? Also, how can I make it so the MOUSE_UP event will fire no matter where on the stage the mouse cursor is.
I can't seem to figure it out because the MOUSE_DOWN, MOUSE_UP and MOUSE_OVER for the different objects have the eventListeners created in different classes.
I have some code that draws a line that follows the mouse and fades away over time, until now it was in the main file of my program but i want to make a class out of it for later use in other programs. I edited the code into a singleton MouseHandler class with one function that registers the mouse up and down events; with trace and 'hasEventListener' I found out that the events are registered but nothing happens when I press my mouse buttons.
Here is the class
package {
import adobe.utils.ProductManager;
import flash.display.DisplayObject;
import flash.display.DisplayObjectContainer;
import flash.display.MovieClip;
import flash.display.Sprite;
[Code] .....
In my main class I just use
MouseHandler.getInstance().startListening(this);
I have a special canvas class covering my entire stage, and a bunch of Sprite hotspots on the layer below. If I put the hotspots on the same layer as my canvas, the canvas does not register MOUSE_DOWN events if my mouse is inside one of the hotspots, since the hotspots are targeted instead. However, if I keep the hotspots on the lower layer, the canvas handles all the MouseEvents. Is there any way to make MouseEvents target more than one thing, so that both the canvas and hotspots respond to MouseEvents? (The canvas is a bitmap drawing class and the hotspots are supposed to trigger when the cursor touches them or clicks on them.)

and would this mean the same thing for this usage?

I made a spiral in pv3d using a mc for material and added a listener for the mouse events.Now the problem is that when i rollover my mc the rollover tween start and directly start the roll out tween.The clickhandler is rendered useless.So before adding tweenlite to the class everything works fine?
