Flex :: Power Function Fit To Data Set
Jun 6, 2010I have a set of data (in ArrayCollection) and I need to fit a power function { f(x)= B + x^alpha } to it, before display in LineChart. As result I need the alpha and B paremeter.

I have a datagrid with itemRenderer in datagridcolumn as my custom component(c1). I am getting the dataprovider data in custom component by overriding the set data function, it is fine. But now my custom component(c1) is also having another custom component(c2).
Now the doubt is - how to get the dataprovider data in c2 component?
In flex, I am handling event like this,
myImage.addEventListener(MouseEvent.CLICK, redoOperation);
Now, I want to pass some value to redoOperation. (function redoOperation myId:String)) How can I pass String to it?
The Following code seems to only be working when i have editable="true" on the Advanced Data Grid. But I don't want it it be editable.
The docs don't say anything about it needing to be editable, and i dont see why it should need to be.

a_data_list.addEventListener(AdvancedDataGridEvent.ITEM_FOCUS_IN, clickedRow);
public function clickedRow(event:AdvancedDataGridEvent):void
{
trace("datagrid line was clicked");
}
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) );

I've been wanting to learn to work with Flash for awhi l e and decided to start learning by attempting a game. I found a decent tutorial for a space shooter and used it to create the basic code (firing, etc...) and now I've been figuring out how to add other elements (splash screen/scrolling screen).now I'd like to add power-ups but can't figure out how.I've created a graphic, turned it into a movie clip, but can't think of what to define for its actions.

View 6 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?

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 2 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. The only information given by the player is an angle and a power. There is also some level elements like wind and gravity.
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.
I have this little crumby thing I'm working on. And in it, I draw a circle with a radial gradient fill. Then I add that circle to the array: "colourSplodeArray"

I've taken out some other unnecessary codes, but as you can see Name position is set according by the position + width of Message, but I want Message's width to be not smaller than Name
Please provide the feature to disable the system screensaver & power saving features while a video object is currently playing a video. I get this request all the time when developing video players and now that the netflix player provides this feature it is becoming a must have in the online video market. If you know other solution which does not require .net, silverlight , or any other browser plugin besides flash please let me know.
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.
Basically there will be a club and a ball. You can control the power and angle to hit the ball. How do I go about implementing this? Is flash the easiest way to go? I want to implement this as a facebook game. Any game libraries specific to this I can use to quickly implement a basic version? I am comfortable with Java and PHP.
View 1 RepliesSo I've set myself a little project to build a bowman game. Everythings working smashing until the math at the point where the computer needs to figure out the power and angle to shoot the arrow back at you. What I've been working off is my knowledge from applied-math classes in school. I've been using the following formula where g is gravity, t is time (this would be in frames for flash), sx is the distance between the players, u is the initial force of the arrow and a is the angle we need to find. With a bit of moving around to seperate the angle, this becomes For my AS3 this translates to:
[Code]...
What happens is that it always fires the projectile at a very low angle that doesnt change to match the correct circumstances and I can't figure out how to get around this. Changing the force doesnt make any difference and the program will need to get around changing distances between the player so this math is pretty necessary (I think). Any math heads out there know what I should change?
In flex 3 I have a hierarchical data structure. I would like to display the content of it in a tree. My problem is that I have nodes which data calculated from children nodes. How to structure the hierarchy to make automatic changes to those parent nodes, if their children's data changed? For example:
Every node has a warning flag. If some of the children warning flag changed to true, then the parent warning flag should change automatically set to true. A node integer field is the sum of the children integer fields, and if any of the children changes, the parent integer field "calculates" the sum immediately. Is there an easy solution wit good structuring changes happen automatically, or I have to make some custom functions?
I have to populate an Advanced Data Grid which have the following fields: Continent->State->Society-->Actual Value-->Estimate Value I want to simulate a financial market so i have to change some of the values by asynchronous request from an HTTPService; If necessary i'll post the .as file, but it is generated automatically by Flex Builder.

I want to separate the data from the PHP call to Different CollectionArrays So that I can use the data for a bar-graph;
I created a static version of the bar-graph and separated the Collection array manually I don't want this done manually I need to do it dynamically. So what I am trying to understand is where to put the event-listener how to add to a collectionArray then once the collection array(s) are built. use that information to build the bar graphs...
