I am creating a flash animation for my physics class. I am demestrating free fall. I know how to create a free fall object, but how would I make it so that the user can change the gravity?

i would like to see if it is possible to have a user permanently change a variable that is utilized in the website. for instance, the width of a line is set to 1.0 in the script - through a keystroke the user can change that width to 2.0. what i would like to happen is have the value of 2.0 be permanently set so that when the next person visits the site, the width is set to 2.0. i know this is a simple example, but i would like to get the concept down first before i venture into writing out the script and doing something more interesting with it.

instead of setting the intervals, i want to change it into something like adding a textbox for users to enter the intervals. and i also want to try to change the codes so that only when the user click, then the arrow would move. so its two separate favors.... 1.adding textbox.... 2.using onMouseDown function to move the arrow.
var targetIndex:Number = 1;
//var xValues:Array = [100,200,220,300,330,370];
//var yValues:Array = [100,150,220,300,310,400];

I worked on a new Flash project, but I cant seem to find a good solution for how I want my objects to collide. In my project I have: a Ball(moving object) and a Floor(not moving).
The ball is positioned over the floor and drops onto the floor through the gravity that is applied with the code.

Is there a way to have a global gravity in flash AS3. In which you could choose what objects you want to be affected by it? Is there a way to have a block of code that separates moving from still objects and will not let any objects collide(not overlap)?

First: the -23 in the code is what I don't like.

I have a PopUpButton that only contains 2 actions. Both actions are complete opposites of each other and switches a boolean property on an object from true to false or false to true. To avoid redundancy, I've only displaying one action at a time. So, if the property is true, the action to change it to true is not shown.
If my PopUp menu has a single option, I would like to remove the menu from being shown and basically revert the PopUpButton to act and look like a regular button. So far, I haven't really found a good way to do that in ActionScript without adding, removing or modifying styles for the button.
Is there a nice way to simply tell the button to hide the PopUp toggle? PS: In my specific example, YES it might be easier if I just used a toggle button. However, I want to reuse this button when dealing with an Array of objects. If I have more than one, the property could be true and false at the same time. In that case, I want to show the menu so they can choose what option to set all the object's properties to.
Is it posible to make a flash site, which will change the size when the vistors resolution is diferent? Practicly, every visitor will see the same size of the site, even if he has 800x600 or 1280x1024??Maybe making html go fullscreen but make the swf occupy only 80% of the screen, so it always have the same proportion to the users monitors.Do you have any example?

I am using Box2d 2.02, and am having trouble with setting linear velocity of a body in 0 gravity. When I trace GetLinearVelocity() when left is pressed, it reports the correct vector (-20.0, 0.0) but the body does not move. It is a dynamic body.
Code:
if (Key.isDown(Keyboard.LEFT)) {
if (mover.IsSleeping()){
mover.WakeUp();
}
mover.SetLinearVelocity(new b2Vec2( -20.0, 0.0));
}
I have a textfield that is filled by a querystring.
example: http://www.domainname.com?dName=Michael+&+Mary+Heatherbaum
myTextfield.text=myQueryStrings.dName.toUpperCase();
If the persons name is only 3 letters I want the font size to be 120 but based on the amount of characters, I would like to shrink the font size in order to fit the whole name inside the text field. I was playing with autosize, but couldn't get it to work.

I'm looking at some requirements for an upcoming flash project. One requirement is for the browser url in the address bar to change as a user clicks around in the flash movie so that a user might copy/paste said address into an email and another visitor will be brought to the same location.

View 5 RepliesI have a separate html page that does this with a php script,reating that php file which is just a form that allows users to enter a passcode that I provide them which will then simply link them to an external html page. Since I don't know about php, I am thinking a possible work around would be to have a text input box which would allow a user to enter (passwordA) then click Submit to load (pageX.hmtl) or they could enter (passwordB) and Submit would load (pageY.html)
View 13 RepliesThis seems like someting I should already know but I am working on a user interface that I want to be skinable. I have about 8 different graphical elements and I want to change the appearance of these 8 different movieClips just by clicking a single button. I thought I would just create a new keyframe in my main time line and then manipulate the movieClips but that changed the appearance of the movie clip on frame 1 as well. Clarification: I want to change the color of my user interface background and I want to change the color of some clickable images as well. I want frame 1 to have a white background and I want frame 2 to have a red background. Do I need to create more movie clips and drag them onto my stage or can I just use the existing movieClips since all I really want to do is change colors?

At run time, Is it possible to detect the 'Connection Speed of the user' and change the way my preloader works?

View 4 Repliesi have a game where fish fall out the sky and a penguin on ice skates has to catch them before the fish get to heavy for the ice, the ice cracks and the ice skating penguin falls into the water and freezes. I have all the code but cant work out how to set the random location along the Y axis for the fish to fall. I have a gravity script but cant work out how to include the random position for the fish. There are 30 fish and i want to be able to have one fish fall wait a half a second and have another fall and so on....until all 30 have been dropped...
My gravity script is this:
ymov = 0;
grav = 2;
_root.onEnterFrame =function() {
ymov += grav;

Anyone know how i could set a random location in this or something similar?

How do I do this in actionscript 3 ? And is it possible to do this within the fla (no class file).
