The question is simple; I need the fastest way to calculate power 2. I need that for this formula which calculates distance between 2 points.var Dist:int = Math.sqrt( (mmx - ox) * (mmx - ox) + (mmy - oy) * (mmy - oy) );

how to deal with unsorted arrays to get the next higher or next smaller value?
var _myArray:Array = (1,pizza,2,6,8,test,11,16,17,cola)
_myArray.splice(4,1) // > remove number 8 !
trace(_myArray) // > array contains now: (1,pizza,2,6,test,11,16,17,cola)
how can i get the next higher value (= 11) ?
I need a good Flash strategy for creating an ordinary PowerPoint presentation. We always need very media-rich presentations (PP is weak in this area). So far we have relied on embedding a Flash object in PP. This turned out to be a bad move because many of our clients deal with the Defense Department and are not allowed to D/L and install the latest Flash player. I have found that publishing a Flash movie projector (.exe) that advances slides like a PP is a good solution. The problem is that I have to put buttons on each slide and write unique functions to advance the slides I would like to be able to simpley click the mouse or use the arrow keys (like PP) for navigation. Should I use the "Flash Slides Presentation" template?

View 3 RepliesI want to make an application with Flash CS4, to open to read inside either pdf either power point. I have some doubts.First: How I can open and see pdf document ? (an small application it would be ok to me, but I haven't see in samples).Second : can I open ppt ? I think probably not, but I am not sure. I read that with flashpaper you can convert ppt to swf, but that's not good to me, the user must select a ppt, and then the application must show it, but if that's not possible, I would like to known if I can load ppt, and the app internaly make the converts needed and then show it.
View 1 RepliesI'm building a website where I hook people up so that they can anonymously vent to strangers. You either choose to be a listener, or a talker, and then you get catapulted into a one-on-one chat room. The reason for the app's construction is because you often can't vent to friends, because your deepest vulnerabilities can often be leveraged against you later on. (Like it or not, this is a part of human nature. Sad.)
I'm looking for some insight into how I should architect everything. I found this neat tutorial, [URL], which suggests using python & stackless + flash. Someone else suggested I should try using p2p sockets, but I don't even know where to begin to look for info on that.
I have the following function in my FogOfWar class, it calculates if its team can see the position that is passed on the arguments:[code]My problem is that, with only 3 characters in the game, it can only run 4000 times per second, which is not too much.I can implement a cache, so it caches the most commons positions, but, what else can I do to optimize it?
View 2 RepliesWhat is the fastest and most efficient way to get RGBA from an image you don't want to display?
I don't care if it uses air or is backwards compatible with a previous version of the player.
Should I be using file io and reading in the bytes and writing my own parser?
Maybe loadBitmap and getPixel?
Are there certain tricks and optimizations to prevent excess work on the player's side?
I'm trying to figure out the fastest possible way to load a .png image into a BitmapData object. I am performing multiple processes that do this (load a .png from filesystem). The progress is shown using a loading bar, and I would like to speed up the loading time. Now this process can be called over n number times (via a timer). Right now the method I am using to this is:

I have searched google for an answer to my problem, but to no results have helped me to solve it. I am trying to find the fastest possible way to load an external .png (as the title suggests). The reason for this is because I want to speed up the loading time of my Adobe Air Application. It loads in a various number of .png files (with transparency) and displays them in a tilelist via Bitmap.

This code calculates the distance between 2 points by using distance formula, Math.sqrt ( (x1 - x2)^2 + (y1 - y2) ^2). My first point has mmx and mmy coordination and second one has ox and oy coordination. My question is simple, is there any FASTER way for calculate this?

Im using a lot of movieclips in an app.Its hitting the performance limits.Im using .png files in animated movieclips.Looking in the clip it says bitmap as type.. source...pngI used .png because i want the alpha background possibility.I then went into some of the movieclips and changed properties convert to bitmap (althoug technicly they already were according to flash)After this i feel the performance has slightly improved.Is this true or just in my mind & wishfull thinking.
View 3 RepliesI need to know the best method to find an item inside a list (Vector, Array, Dictionary, whatever is faster) of complex type (extensions of Objects and Sprites). I've used "Needle in Haystack" method, but it seems that it isn't fast enough.
E.g. Suppose that I have a collection of Sprites (a pool, in fact). Each sprite will be added to the stage and perform some action. After that, it will die. I don't want to pay the cost to dispose it (garbage collect) and create another (new) one every time so I'll keep the dead sprites in a collection.
Sometimes times I'll call a method that will add a sprite to the stage. This sprite can be a old one, if it is already dead, or a new one, if the pool don't have any free sprite.
One of the scenarios that pushed me to this question was a Particle System. A "head" particle leaving a "trail" of particles every frame and exploding into a flashy multitude of particles... Every frame...
Some times this counts up to 50.000 PNGs with motion, rotation, alpha, event dispatching, scale, etc... But, this is JUST ONE scenario...
At the moment I'm trying to use a Object Pool with a Linked List... Hopes that it will be faster that running a whole Array/Vector or create new instances every frame an let them dye with Garbage Collection.
why aren't they working? need any more details?

View 1 RepliesI've got my 3D sphere to triangle collision detection working now, but I need an efficient method of adding the triangles to the broadphase grid.
This is easy enough if the triangles are smaller than the grid nodes, however - especially given the polycounts I'm working with - it's going to be fairly frequent that a triangle is significantly larger than the grid nodes.
Here's an example.See the yellow polygon? Just adding it the grid nodes by it's vertices results in it NOT being added to 4 grid nodes that it does reside in.
My first thought is repeatedly casting rays along one of the edges from the normal of the edge until you find the intersection point with one of the other edges, of course checking for intersections with the grid edges until you reach the destination intersection with one of the other edges of the triangle. This would work, but is not particularly fast.
Although these triangles aren't being added/removed in real time, only when building the level, when constructing a level with say 100,000 polygons total, I obviously want it to be processed as quickly as possible.
I've been wanting to learn to work with Flash for awhi l e and decided to start learning by attempting a game.

View 1 RepliesI have been trying to implement the Round Up Power Of 2 algorithm outlined in the following link in AS3.
[Code]...
The algorithm works great for most of the values I've tested. It is mentioned that this will return 0 when given an input value of 0 which is technically incorrect but I'm ok with that output. What I'm not ok with is when given an input of 1 I get and output of 1. I'm thinking that this must be a caveat of AS3 and its wonky uint implementation but I can't seem to figure it out. I have also tried using the >>> logical shift operator to the same result. My C is a little rusty, but I'm not sure how this would even return 2 in C. Can someone explain to me whats going wrong here? I assume if an input of 1 was a special case it would have been mentioned in the above link.
I have an MC that occurs many times on the stage, and each one has a motion, and random scaling script in it. Would I save computing power by not having a script in each MC but rather assign them all to a prototype?
View 14 RepliesI'm making a 3D program and I've already made the back end which calculates where each object's polygons should be. However, I can't seem to find a quick way of drawing them without having to remove and redraw them each time, which I'm sure would take a lot of processing power, knowing the way that Flash does things. So is there a way to draw a shape (a quad in this example) and then alter the shape's color and the position of all of its corners in the next frame without taking a huge load of processing power? I would really like to be able to do this to at least 20 polygons, hopefully more, within the span of one frame at 20 fps.
View 3 RepliesI'm doing a prototype game like Worms and I would like not only to shot, but also see the whole projection curve where my shot will travel before it hit the ground.

Can I have a code for the projection curve? its like a parabola I think. I research about parabola but I had some difficult to apply these math formulas into the programming code.
