ActionScript 2.0 :: Lines Between Dots Approach: Efficiency?
Dec 20, 2006
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.

I am drawing some circles with a bit of code like this:
Code:
for (var i = 0; i<=1; i++){
for(var j = 0; j<= 1; j++){
this.drawMyCircle(radius,i*a,j*b);
}}
//a and b being the gap between the columns and rows
What I would like to do is add some metadata to each point I create, containing the centre coordinates for that dot (e.g. i*q, j*b). I have no idea about this part. Then with an onRelease event on a given dot , I can get the location. I have never dynamically made an event firing object. My goal is to be able to draw lines between two clicked dots. Unfortunately I have to do this dynamically so I can introduce a bit of variety.

I've got a long list of code which I think can be made far more shorter by using a 'for' loop, however, I'm not entirely sure how to go about this? Here's the code I have at the moment
if(event.target.hitTestObject(zone0_mc) && zoneFull[0] == false && event.target._ballPlaced[event.target.name.substring(4,5)] == false) event.target.x

Say I have 100 MC's (movie clips) in my scene that are spreading out in _x and _y. On every frame I need to check each of those MC's for a hitTest (or anything really). Would it be more programatically efficient to:A) Create a single array to hold all the MC's and do a for...loop to check all of themorB) When each MC is created create an onEnterFrame to check only itself (x100)?Hope this makes sense. This is an argument between me and my partner as to which will be the less processor intensive. My theory is that there would be no difference but I've read no documentation for it

I'm creating a music player to be on my website and so far I have it set up as such: The player is contained in a movieclip with a 'song progress bar', a pause and a play button.The songs are played by clicking the song title in a list in the main stage (not contained in the player movie clip), which sends the music player to the frame in which the song starts.
My audio is set as event audio so that the play and pause buttons can be coded as play(); and stop(): respectively which will stop the main player movie clip thus yeilding the progress bar from moving further and the song from playing.
This works just fine, except for the following:
- When I select event as my audio type the quality reduces dramatically Having the audio files in my library and not obtained from some outside source (i.e on my website's server) causes the .fla file to be much larger as well as the .swf Being as my project is at 24 FPS and each song is represented in as many frames as it takesto play the song out, my music player at present has only 3 songs 'in it', and my frames in the movie clip are approaching 20,000 (this is VERY tedious to work with)
I'm sure there is a more efficient way of doing things, but my knowledge is limited. I'd imagine I can do something along the lines of loading .mp3's off of my website into the frame and the play pause buttons will enact more elaborate scripts that not only stop the progress bar but also stop the music from playing temporarily, or something like this. But I have no idea how to implement it

this is the offending bit of code:
for (var i in yearMarkersArray) {
yearMarkersArray[i].x = ((timelines.x + 350) % 140) + (140 * i) - 5;
yearMarkersArray[i].text = "0";
}
This is part of the main loop that triggers whenever the user drags the zoomed-out timelines (the sprites in eventsArray) left or right. The six TLFText objects in yearMarkersArray appear to scroll left or right with the user, but are really repositioned and relabeled with the correct year markers as calculated by a function I did not include above (it's working and not relevant to this problem, I simply replaced it with the "0" for clarity).
The text-setting statement is the problem code...I've commented literally everything else out of the main loop to verify it. I even changed the statement to not involve any function call (simply setting the text attribute to "0"), and it still causes the final .swf to eat an extra 1% of my CPU every 15 seconds until finally the FPS crashes through the floor. The rest of the main loop has much, MUCH more complex and I'm sure inefficient code that also runs every frame,Since this project reads a data file with a list of timeline events whose span of years I cannot predict, I do need the displayed year markers to be done dynamically in some way. The code ultimately works (I only noticed the ridiculous slowdown when I accidentally left the movie open and idle for a few minutes),

I wrote a class for an object that as soon as it is created moves around the screen and can create another object (replicating itself). That seems to work fine for a while, but after like 20 or so objects on the screen things slow down a lot! I create the first object on frame one. The rest is all done by the objects themselves.
Would it be better if the objects did not move around on their own, but rather through a loop on frame one or does it not matter? I am working on a simulation that should go up to over 100 objects, but with this problem can't get there. The object is just a movie clip (imported png picture about 4 by 7 pixel, not animated). I was going to replace it with an animated one later, but that seems unlikely now.

My code is on the main timeline.I call a function loop to draw lines between them.The lines are drawing between the right x, y values BUT between those values on the main stage, not those values within the kite.For example, dot1_mc is at x100, y0 inside kite. the line that should go from its center, draws from stage x100, 0.How do I draw the lines inside kite so that they draw between the dots?Heres my code that draws the linesPHP Code:
function loop():void{ lineDrawing.graphics.clear(); var a:Point = new Point(kite_mc.dot1_mc.x, kite_mc.dot1_mc.y); var b:Point = new Point(kite_mc.dot2_mc.x, kite_mc.dot2_mc.y); var c:Point = new

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.

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.

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 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...

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've been slowly teaching myself AC3 - largely using examples from online tutorials and a collection of books I've bought. I can get simple exercises to work, but I'm losing my way when things get complicated.
For example - packages - I am unclear on how these work and interact with my main programming stream. Now I'm getting to the point where this question seems to be coming up all of the time. But, for some reason, I just can't seem to connect the dots.
