Actionscript 3.0 :: How To Approach Dynamic Light
Mar 9, 2012
Our game is a bird-eye view game, with a dark atmosphere. The player carries a flashlight which can be used to brighten up the environment.So far, we've tried using masks, and although it works, it's not very effective. Every object needs a seperate mask, it tends to use a lot of CPU and is generally a mess to work with.I've considered using a system of black tiles at 90% alpha all over the room, which change their transparancy when the player moves near - but I was unsure.

In an effort to learn the technology and languages I'd like to try to develop my own Flash Video player (for the web).The main goal would be to brand the interface and be able to stream/play flv video files over the web on websites.I have no idea where to even start looking for information or what to look for on this topic

The intent is to implement a zoom effect for my photo gallery where photos are displayed at a default size when looking through them but if clicked they will zoom/scale up to a larger size for a more detailed view of them.I've attempted to do this by loading the jpg at it's full size when zoomed, having a Bitmap draw it, then immediately scale down the Sprite container that holds it. I call this scaled down version the default size. When the user clicks on the Sprite shown at it's default size, it is scaled back up to it's original size using a tween to give it that growing larger zoom effect. I call this larger unscaled version the zoom size.
The problem is with the default size (scaled to .66). It is not very sharp and has a noticeable lack of detail. I've compared the quality of it to a smaller jpg (equal display size) of the same image and the smaller unscaled version looked way sharper. I have set smoothing = true; so the tween responsible for the scaling will appear smoother. The tween looks perfect and so does the zoom version. The default version of the image when it is not being tweened is what looks bad

I am not very code oriented, but I found this code that I altered for my needs, and it works, as you move your cursor towards the bottom of the screen the movie clip fades in. However, in addition I need one that does the inverse where another mc fades in as you approach the top. Does anyone know how I would acomplish this task?

I come from game programing using c++ and glut (which is an external library to display sprites and stuff). in glut you do everything in the code there is no drag and drop, this is nice since all the control is at the code itself, this is also annoying because when you want to display something you need to guess the right coordinations, this requires a few tests until you get the right coordinations.
Now in flash you do have the drag and drop feature which is great but it doesn't go well with the OOP concepts, at least for me.my dilemma is: do you create your frames (symbol creation and placement) by code only (but miss the drag and drop freature of flash) or do you create pre-made frames by drag and dropping symbols from the library?

What is your approach to writing documentation explaining the options and use of XML files for a project ?Do you write commented instructions directly in the XML file ?Do you create a different text file in which you write instructions ?Do you explain the use of blocks of XML or do you detail each element and it's function ?I am looking for some guidelines on how to write the documentation for large XML files that control the settings and content of projects.

But I do not want to Drag and Drop the original movieclip (A). But a copy of the clicked movieclip (A1).To do this I make a copy of the clicked movieclip and put in on the same place as the original one. And set function A1.startDrag();The problems which i have now is the handling of the mouse events. Because Flash was bussy with movieclip A, and is now interrupted by movieclip
.onPress {
make moviclip 1
set location A1 under the mouse cursor

I've got a question about the efficiency of two functions I wrote that do the same thing. I'm trying to figure out which one to use. The functions draw lines between a series of points, and continually redraw them as the points move. The first function uses the drawing functions in flash.The second function creates an empty movieclip and draws a short line in it, then uses trig to scale / rotate the movieClip to make it fit between the dots.Both work, but as my program gets larger I'm wondering which function would calculate faster.

it looks like with the createEmptyMovieClip, u need to pass to it an instance name of an already existing movie which has been created manually and put in the library.I dont want to create an instance of a movie clip in the library. i want to create a movie clip in actionscript that does not already exist in the library.

I will redesign a product page that contains products like Vase, Ceramic Plates and more, Customers can customize the colors of the product. Now I need some advice what approach would best fit, I am planning to use Flash/Flex/Actionscript in implementing this; That way I can minimize loading to many jpegs for the product and at the same time making the page more interactive.

I am having trouble figuring out how to build a console for my application so i can send msgs to it from any class in the package.
i tried to send a generic Event, but I cannot find a way send a msg together with the event, or at least a reference to the object which is dispatching the event.

For my application I need a component (or combination of components) that shows a number of different types of events along a timeline, displays them in different ways as specified and allows you to click/hover along the timeline to add/modify/get details on events.
Basically I want a timeline across the top, always showing a 24hour period, but starting at variable points. I need to have different rows of variable height to display different types of data in different ways. for instance: row 1 will display the 'value' attribute as a circle whose diameter reflects value amount and change color based on a 'typecode' attribute. row 2 will display a line graph and plot chart based on different numbers (like one chart but with the datapoints as larger dots), and will also chart out trend of following or previous data if it exists. behind row 2 will display the same thing but for 5 previous days progressively more transparent

I wish to create a multiplayer game facebook app. A game will have 1 to 4 people in it playing from their own systems. I wish to target, lets say, 10K simultaneous online users. I am planning to write the client side game in Flash. I wanted to know how these clients communicate with each other. Can these clients communicate directly with each other or I should go with "server as middleman" approach? I want the game to work even in "restricted" networks. If server, how do I have things working from google app engine cloud service? I came across channel API, should I use that? Would it work with a flash client?

I'm looking for the javascript way to an associative map/array/hash that's using objects as keys. A replacement to what you can do in ActionScript 3 with the flash.utils.Dictionary. I'm sure java and C# have something like it too.It'd work same as a normal generic Object based assoc[key] but instead of string-based properties you use whole objects as keys (it will match not on toString() like Object does but on unique instance). Very handy to decorate objects you don't own (by using the object as keys and your decorations as value).[code]Main point of issue is I need to match on object only (it's being used by some other process you're not to interfere with but we still need association). So no magic .__hash props or toString() overloading (if possible).

Working on my first real project in as 3.0, trying to decide how to best work in a preloader. What I have is a single swf containing some assets, and a target to a main doc class. After loading those assets onto the stage, it runs through a routine to load several other swfs, and then 'does stuff' with them... anyway. got all that working nicely. How, now to best track the loading of the main swf? If I understand it correctly the Loader class is purely for loading external assets. well - what about internal assets?
Got this:
ActionScript Code:
//A large SWF file can monitor its download by calling
this.root.loaderInfo.addEventListener(Event.COMPLETE, func)
I think it would be called AFTER the whole main.swf has loaded. In AS2.0 i could target _level0 to get information back about the currently loading swf...
ActionScript Code:
initPercent = (_level0.getBytesLoaded()/_level0.getBytesTotal());
But, again, these are internal assets, not even living in memory yet. As far as I can tell - I need to use a preliminary (separate) swf to load the main.swf. (Like i used to do with AS2) - But if there was a method of targeting internal assets - a 'self loader' that would be cleaner...

I have a 6 button menu system: when user clicks on a main menu link it will highlight red and light up a light right to the left of the link letting them know they have clicked successfully. After the initial click it will bring down a sub menu with links. However, after they release the mouse button, the little green indicator light goes off. I want that little green light to stay on until they move the mouse outside of the slide panel with the sublinks. how do I keep that light on until user moves mouse outside of the bounding area of the sub-panel with sub links? what code do I need to insert?SECOND:When I go to publish in html, my slide panel which contains the sublinks is chopped off. How do make it were the submenu goes over and on top of my webpage contents right below it instead of increasing the size of my table.
Here is a copy of my code. I will be posting an image in about 30 minutes or less:
// ON CLICK EFFECT - The main menu's sub-menus will slide down once user clicks on a button.// The sub-menu will raise up and disapper once the user's mouse leaves the sub-panel area.
import fl.transitions.Tween;import fl.transitions.easing.Regular;import fl.transitions.easing.Elastic;
stop();

it's an animated website header / banner
my stage is a long, thin rectanlge, with an asphalt background on a distinct locked layer
on the stage i also have a movieclip of white crosswalk 'stripes' motion-tweened from left-to-right over the asphalt
i am trying to have these stripes fade away as they approach the right side of the banner
'fade' being the operative word here, i'm trying to create a mask layer in the 'stripes' movieclip that has a transparency gradient
basically, a recatangle moves left-to-right over the stage, and a mask layer above (aligned left), has a left alpha value of 0, so the rectangle disappears behind it. i've seen references to 'soft mask' and also animated AS solutions, masks are always far too complicated.

I want to make a pulsating spot that looks like red light. The pulsating effect is done but the circle with gradient red goes from red center to black. I want it to go from red to nothing/transparent, so that whatever background can be seen through the edge of the "light". Is that possible? I use Flash 8.

I am in the middle of designing a 16 x 16 grid sequencer with a row of buttons that light up and sweep across the screen as shown in the attached picture. Basically i was wondering would this be best done in flash cs5 as its hopefully going to be coded with actionScript or should i use other adobe apps like illustrator etc? I was also wondering how to get the lights to trail behind as the lights travel across the buttons?
Just a quick query, i work with Lightwave 10 on the mac and i was wondering it it can be incorporated into flash cs5 at all?

in order to use removeMovieClip, I think I have to use attachMovieClip first, right? What I want to happen is drag and item with the mouse, and then on release make it stop dragging and make it look like it returns to its original spot.
ActionScript Code:
mirror_inv.onPress = function () {
mirror_inv.swapDepths(1);[code]....
Also the commands attachMovieClip and removieMovieClip don't light up in AS. However just attachMovie and removeMovie do light up, not sure if that is same thing..

I am really new to Flash n Actionscript and have been dropped in to make a switch that will make a light come on in the first click and off on the second, on on the third and off on the forth etc... I have created the switch as a button and the light on/off as two movie clips....
What coding would i be looking to add to make this switch work...
Previously I have been given this... but its not working
//this is for the button (switch)
on(release) {
if (_root.light_on:active == 1) {
setProperty("_root.light on", _visible, "1");
_root.light_on:active = "0";
} else {
_root.light_on:active = "1";
setProperty("_root.light_on", _visible, "0");
}}
//This is for the light on
onClipEvent (load) {
active = "1";
setProperty("_root.light_on", _visible, "0");

I'm trying to get a light that is hanging from the top of the page by a chord to be drag-able and then for them to be able to let go and the light swing back and forth. Right now I've got a pretty cool as that is onLoad it will swing and gradually slows down until it is sitting still, but I'd like to have it have a little more elasticity added to it for them to be have some fun with the hanging light..

I'm using shapes drawn to sprites to try and get a fog of war effect.Basically, I have a large black rectangle that goes over the screen as darkness, and I need to have multiple towers that have vision fields that would cancel out the darkness.I'm using masks too, but I can't get the right effect.

So I was working on making a button that will light up when I scroll over it, not instantly but more realisticly. The button starts out gray and when I scroll over it I want it to fade to red.
So I made a new AS3 Flash file and drew a simple gray box, made it a button, and inside the button I made the box a Movie Clip, shape tweened it so that it fades from gray to red in a period of 5 frames.
Now I'm just stuck on the scripting part, I made a new layer inside the movie clip for the script and have this typed in:
Code:
import flash.events.MouseEvent;
rectangle_mc.addEventListener(MouseEvent.MOUSE_OVER, mcOver);
function mcOver(event:MouseEvent)void{
play.rectangle_mc
}
I don't even know what import flash.events.MouseEvent; even means.
But what I'm trying to accomplish here is to make the shape tween Movie Clip only play when the cursor is over the button. So that when I scroll over the button it fades from gray to red. Sounds like a plan, but I can't figure out the function part where it says play.rectangle_mc,

I have got this menu from intronet and got it working, now am trying to be tricky, I want to have a way to make certain buttons light up when on a particular page, so for example I have got Brian's Vision button taking me to frame 2. How can I get certain buttons to be highlighted on that frame?Basically in my code so far I can listen to a button that is clicked and determine what text it has.. so who can I identify a button with a certain text and make it do something (without clicking on it?)
Code:
ans1.ans1text.text="beans";
ans2.ans1text.text="chicken";
ans3.ans1text.text="rice";
