I wrote this 9ball game a while back (never really finished it), and was showing it to a friend today. When a pool ball is rolling fast, less of it's mass should be touching the felt, therefore, less friction. As it slows down, there should be more contact with the felt, and therefore, more friction. Any realistic algorithm to use to adjust the friction higher as the balls slow down? [URL]
View 11 Replieswhen I'm running and not holding my keys down then the friction should slow me down. That works but the speed never stops at zero. I can't see him moving but I've put a text that draws his speed, because if the speed isn't zero and I'm not pressing any button then he will slide and that doesn't work look here: [URL]
The code in the player I use is:

I have a billiard ball system, whic detects collisions between balls and modifies their x and y velocities accordingly.I have included a friction variable and I have a very basic system for applying the force of friction for each iteration of movement:
private static var FRICTION:Number = 0.94;
public function move() : Void[code]....
This works to a reasonable level of satisfaction, but it doesn't quite feel right. The balls seem to take just a little too long to stop when they've slowed down to a very small velocity. I've tried tweaking the friction constasnt, but I still can't get sometthing that feels exactly right.
I wrote it through the equation (n, k) = n!/(k!(n-k)!).But I found it will loose precision quickly after 12th row.So I change the way. I tried to use the properties of triangle(each row is the sum of previous row)Than I get slow in running when function reach higher degree.
I just keep changing a little and a little... try to make it run faster.

View 1 RepliesI'm used to applying basic friction like this:[code]The problem is I don't know how to convert this to be described over time, so that can reduce the value based on the amount of time that has passed.Say I want to reduce the value to compensate for 1 second passing, or 500ms? How does that work in to the equation?

Without adjusting the fps how would I slow down an object that I have rotating CW 1 time?
View 4 RepliesI'm attempting to make a racing game. I want to make it so the user has press two other keys alternately in order to speed up. While the user is not pressing those keys the player should slow down gradually. I'd also like to add friction. Right now, I have code for basic movement:

I for the life of me can't figure out this simple equation that I want for a camera-following function.As distance decreases, friction increases.Friction being a number between 0 and 1, where friction = 1 is no friction.

I have an idea for something at work. I want to have stars hanging by strings from the top of my flash document. if the user mouses over these stars I want the star to lightly swing in the direction the mouse went over at. Almost as if you had a cardboard star hanging from the ceiling and you tapped it with your hand. I know this probably includes friction but my tests don't seem to work out the way I want. Does anyone know how to achieve this?

I'm working on a project conversion from AS2 to AS3.
In AS2, I used a mainMenu file and loaded a Navigation file at _level 999 (very top). Then I loaded and unloaded different modules on _level 5.I also loaded and unloaded an external Glossary file on _level 95.Now in AS3 I am using AddChildAt(1) for the Naviation file and AddChildAt(.1) and removeChildAt(.1) for the module files. The Glossary file only seems to work at Child Index 1, so I'm guessing it pushes the Navigation file to a higher index. Is there a reference that explains the Index properties of the Child and why sometimes I get an error when I try to add a Child of Index 2 or higher?
I have a movieclip with a prefilled content (some simple vector graphic in a movieclip), with the height of 40. I then apply a mask to it, with the height of 30. Now i would think that the MovieClip is 30 pixel high, but it turns out to be 40 pixel high. Is there some property im not setting or does the movieclip always assume the height of ALL the content within it? or what?
Actually in another clip, too, I have predefined 2 vector graphics (in two seperate movieclips), where the highest one is applied as a mask to the second graphic. The movieclip again assumes the height of the highest element. That might be logical, as it is the mask, BUT! when i then resize my mask (programatically) the height of the movieclip remains the same.Is there some way to recalculate the height of a movie clip? Or am I missing something?

View 2 RepliesI'm trying to make a script that listens to a variable (int or Number) and then does certain functions whether the variable is going higher or lower. So for example if the number gets higher, it runs one function. If it gets lower, it runs another.
View 3 Repliesyou know any reason why a function won't accept any number higher than 4? This is all I'm doing. Works for 0-4, but once I hit 5 or higher, I get "A term is undefined and has no properties." But if I just put the number 5 in there, it all works just fine, so it's not an issue with the xml.. for some reason the function just won't accept anything higher than 4. weirding me out..... I can't see an explanation for it.

In Flex, I am using graphics.codec.JPEGEncoder to save image files that are edited inside application (normal manipulations like brightness etc.) I am able to save files perfectly. What I want to know is that is there any way I can save the image with a better dpi? Say, for instance the image that is loaded and manipulated was originally of 72dpi, now can I save it with a dpi of 150 or 300 ? If so, how to do it.
Doesn't have to be using the JPEGEncoder, if there's any way to do it at all, like using any library etc, I am okay with it.
Note: If it matters, I am using Bitmapdata to store the image and manipulations and saving the image with JPEGEncoder by supplying it's data as bytearray like below.
var imageBytes:ByteArray = encoder.encode(myBitmapData);
I compile a SWF with ANT using FDT. In the compiler arguments I am setting default-frame-rate to 30. When I run the SWF, the stage.framerate property is 30 (which is correct), but as the Stats util from mrdoob shows, the SWF runs way faster up to 52 fps.So it seems the compiler argument default-frame-rate is applied, still the events are fired at a higher rate.[code]
View 1 RepliesIs there anyway of using AS to check if a number is either higher than a certain value, or closer to a certain value. The purpose, if the number in the text box is either higher than the other text box, or closer to say, 500, than the other one, then, it displays something in a dynamic text box.

I'm designing a site at the moment & I've run into a minor snag. I am loading about five external swf's, for each page of the site, from the main 'home' page. you can view it here Trouble with levels. I can load the movies fine, but what I want is to load each new movie into a higher level than the last, as each movie appears with a mask (for an example have a look at the site I've done then click on the 'Contact Us' button - that is what I want to do on all of the pages...) all of the swf's are loaded into level one with the exception of the 'Contact Us' page. (By the way, there is no 'News' page yet)
The very simple code I used to load the movies is:
Code:
on (release) {
loadMovieNum("contact.swf", 2);
}
Am just a begineer with Actionscript but am picking up quite quickly. I been racking my brains and can't seem to find a solution. Basiaclly I've got 5 movieclips on the stage which are draggable. How can i get a message to appear in a text box if the first movieclip is moved higher than the second movie clip?
View 4 RepliesI've just switched over to AS3, and I'm completely stumped with something.
I'm working on a project where I keep adding children to a MC already on the screen. There are two types of these children: Sprites that I use to draw lines using moveTo, lineTo, ect. Then there's sprites that have children inside of THEM that are bitmaps.
For some strange reason, the Sprites with the bitmaps on them always have a higher depth/index (AS3 terminology is still weird for me) than the normal Sprites.
Here's a diagram of my MC/children/children layers:
---------------=> (Sprites that draw lines)
(MC on Stage) =>
---------------=> (Sprites that hold bitmaps) => (Bitmap)
