Some computationally intensive software are now using the GPU to solve mathematical problems. Now that flash has GPU support, is it possible to use flash to crunch math problems? How would it be done. In other words, does flash expose sufficient low level API to control the behavior of the GPU sufficiently to perform such a task?

What i done there i draw a box and made it to movieclip and instance named it hook and created a invisible dot and called it dot. Then I calculated distance from box to the mouse then i took that number and put it in Math.cos command. And finally i made tweener to change box scale depending what my mouse distance from it.So if my mouse is close the box is big , if far - box is small. Ok, I want to know is there another way to do this ? Cuz , i cant think of other way to change arithmetic positive progression(like 3,6,9,12) to negative progression(like 12,9,6,3) than Math.cos command.
Here is the problem:
var p:int = 0;
var n:Number = 0;
n = 32.999999999999999;
p = Math.floor(n);
trace(p); // returns 33
n = 32.11111111111111;
p = Math.floor(n);
trace(p); // returns 32
I would expect both of these to return 32. I have searched, and it seems this is an unreported bug in AS3. Or ... am I doing something wrong?
I'm making a simple calculator, where user can enter values into textboxes and then hit the calc button. E.g.
this.sales_txt.text = "8.50"
this.buying_txt.text = "3"
var marginPerLitre:Number = parseFloat(this.sales_txt.text) - parseFloat(this.buying_txt.text)
trace(marginPerLitre) // = 5.5 <--
I need the output to equal 5.50
Wat is the diffrence between these two?

I have a code in which I have to use Math.round if a certain value is for example 3.67 (67 is higher than 50) and Math.ceil if a value is for example 3.23 (23 is lower than 50). What can I do to make flash calculate if what after the dot �.� in 3.23 (for example) is higher than 50?

There is more to this script, but I cut it down to this in order to focus on the error, which results in a joining aa and aaa. i.e. aa=36 aaa=4 results in a=364, where what I want would be a=40
Problem is that my rewind and fast forward buttons do not work properly in the sense that they start to mess up when you fast forward or rewind past the current scene. It seems to just skip through the whole movie and totally mess up the animation.the code for the controls is on a single layer and reads as the following:
stop();
play_btn.onRelease = function (){
play();

So here is a piece of code that I have seen used a lot but don't really quite understand:
myVar = Math.min(Math.max(myVar, this.min), this.max);
or some variation thereof. I understand that the function first finds the maximum value of two values then turns around and uses that to find the minimum between two values.why this is done? And how do you know when to use it?

View 1 RepliesI would like to know how fast, flash player processes the Mouse movement? Does it process mouse movement at the same speed as the fps(frames/second) of the flash player .
For example for a function added as a listener to Mouse movement say, stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseMoveListener); Does flash invoke this function 'mouseMoveListener' every time the mouse is moved? Is it done at the same speed at which the Operating system handles mouse move ? Or is it lesser? If so, then by what amount?

View 8 RepliesI think I broke my Flash. I'm using Flash CS5.5, and when I use AS3, any references to the Math class give me errors like this:1061: Call to a possibly undefined method sqrt through a reference with static type Class.1061: Call to a possibly undefined method pow through a reference with static type Class.1061: Call to a possibly undefined method pow through a reference with static type Class.The code in error is this:var dist:Number = Math.sqrt(Math.pow(initPos.x - pos.x, 2) + Math.pow(initPos.y - pos.y, 2));What the heck is going on here? Math is a top-level class, so I don't think I should be getting an error like this. Is it possible to somehow "break" the Math class? If so, how do I fix it?
View 1 Replieshow to code where it should move towards (that's easy), and I know somewhat how to use math stuff on flash. But when I tried to implement it on this, it doesn't work. See code:
angleA = Math.atan2(TARGET._y-HERO._y, TARGET._x-HERO._x);
var degrees = angleA/(Math.PI/360);
BULLET._rotation = degrees;
It is correctly placed, don't worry about that.

working on making a flash program that loads about 1000 jpegs and then plays them like a movie. Have all the buttons and stuff working but the time it takes for an image to load is so high that the movie can't be played at 30 fps. I've tried multiple ways of fixing this
using 1 scrollpane and changing its source ever 30 ms. This one is the worst but simplest. Flickers cause strobing and it is unwatchable.
used 2 scrollpanes that were duplicates of each other until I had to load. I would then make that one invisible, load it , then make it visible. Then load the background one. Works but same problem as the first at high speeds, just less severe. used 1 scrollpane per image . This works great, except that it fails miserably on any more than 100 of them due to the number of objects.Currently using action script 3, but will change if its not possible in that.
Also, I want to be able to zoom in and then scroll around the window hence the scrollpanes, but if that's not possible its a sacrifice I'm willing to make

I'm using swfobject to load a flash object on my site and it's loading very slowly on pages with a lot of data...as if swfobject waits until the page loads before loading the swf. Here's an example page with swfobject: [URL] If I change out the swfobject code with an iframe (with the swf as the src) or just use object embed, the flash object loads much, much faster...before the rest of the page loads.
I know there are a ton of page load time improvements I could make to that page (I'm working on that as well), but I'm wondering if there are some specific changes I could make to the way I'm using swfobject to get the same loading speed as an iframe or object embed?
