I'm using a combination of Paul Duncans php ZipStream [url]...
Works fine in Air, but when running Flex in browser, the zip needs to include a Adler32 checksum in the header for FZip to be read.
How can I calculate an Adler32 checksum for the zip in php?[code]...
I am developing an application in flex in which I need to calculate checksum of different files. I would like to know if there is a direct method in actionscript to calculate that or do I have to go for any external libraries?

I'm working on a game which will involve space battles, and automated turrets. The turrets are giving me the headache right now. Here's what I got so far.
[URL]
The problem is, that the turrets aim at the center of their target, instead of aiming in front of their target to compensate for their movement. I can't seem to crack the equations needed to get the right rotation, for the turret to fire from. The data the turret has avaible, or that I could easily make avaible to it, are:
- The distance to the target (and it's x and y components)
- The current speed vector (the size and rotation)
- The angle between the heading of the target and the turret's location
- The speed of the turret's shot (fixed speed)

I'm basically trying to emulate Photoshop's Vanishing Point tool where you can define the 4 2D points and the 3D plane is calculated from that information, in terms of the rotation of the plane relative to x y and z axes.
So if you have an image like this one:
And you define the points of the four corners, maybe like this:
It would define the 3D plane that the surface must live on relative to the x y and z axes. Researching this has led me to some tutorials on drawTriangles and Homographies, but they all seem to be focused on mapping bitmap data and I can't seem to find anything that defines a 3D plane itself.

So i got the ability to add a numeric value to an mc down. So every time i pick up a coin with a value attached to it, and place it on a hand mc, it'll trace the value i've assigned. very excited on this aspect. I've been searching around for the ability to have a master value that I set say for example 5.0. When I hit another mc, this function (that i need to find out about) would check the values that are resting on the hand. I could not find the proper syntax. I have a very good idea of where it would go and what it would look like but I'm missing the forumla. Now I've bold/underlined the area that I think the check would be executed. When you hit the checkout button, it would tally the myValue sums that are currently resting on the hand mc. So my thought train is that I'd declare another variable like masterTotal (the value I want the person to match), and the handTotal (what is resting on the hand).

I have a running total. When an mc hits the table or hand it'll adjust the total. The problem is I only want the total to reflect when an object is resting on the hand mc. If i remove something from it, remove its value from the total. Now to be smart I have it add when an mc hits the hand, and remove a value if an mc hits the table. The problem, if I never touch the hand and keep dropping the mcs on the table, i get a negative value. Is there a way to calculate a total only when a mc rests on the hand mc

I use this script currently to determine the difference between two dates:
[Code]...
The problem with this is I want to monitor the actual physical day change so if someone accessed the application at 11:59 PM and then came back 5 minutes later this would register as a 1 day difference (a new day), this current script requires atleast 12 hours to have passed between two dates for it to register as a new day.
I have thought about using the date number etc, but because months and years are so different it is quite a complex route, there must be something simpler.

For some reason the "scaled.width" - the movieclip that have scaled already - after scaling it even more with TweenLite.to function by factor .3 aren't equal with the predicted result => scaled.width * .3. Orginal width is something I don't know but scaled width is something like 420. Now multiplying it by factor .3 the result should be something like 140, now when I put TweenLite.to function to scale my scaled movieclip by factor .3 the width in the end is something like 267.And frankly speakin I really can't imagine where the result came from.
Some back ground:I import three images dynamically. Each of them to their own MovieClip containers. I don't know the dimensions of images so I need to scale them proportionally to their dimensions to fit to the desired size.That was intuitively easy. I managed also to align them horizontally in the center of the screen after the first scaling by the knowledge that their registration point can be found from the top left corner. I also managed to align each of them on vertically in the middle of the 1/3 part of the empty stage with desired marginals: in the top there are 20 pixels space, between the images there are 20 pixels space and in the bottom there are 20 pixels space.
Now the problems comes when I need to tween them to their final positions. Each of them to the top of the stage and each of them in 1/3 part of the empty space horizontally scaled at the same time smaller with factor .3.Intuitively when I think the x position can be found by same way than the way I found y positions (related to the space left after the middle image is positioned). So in theory I thought the x position for the image that comes in the center should be as much as finalX = stage.stageWidth / 2 - current.width * .3 / 2(the center point of the stage minus the half of the width of the image after the scale)but when I give finalX for the tweenLite as a x position and .3 as a scaling factor the result is something different.
i'm trying to calculate the difference between 2 Bitmaps.One bitmap is an external image, with only black and white.The other one is a bitmap created by AS3 and filled with red.The external image has some basis shapes on it, now in flash i want to know where these shapes are and create a movieclip out of them so i can later use it.Now what i've done is created 2 bitmaps for the image, and 1 sprite to try and make those movieclips.The thing that i have now is this:
Code: Select allthis.trackBmpd = new BitmapData(loader.width, loader.height, true);
this.trackBmp = new Bitmap(this.trackBmpd);
this.trackBmpd.draw(this.loader);

But here i'm kinda stuck, i use the blendmode to see what the difference is, but how can i use this blendmode to create those movieclips out of it?
im creating a site with one frame and one swf, some images are call from an XML file populating som mcs, i have just made a second SWF with the preloading(just like lee´s tutorial), but the problem is that only calculates the size of the SWF(content) but not the size of the images from the XML, so i have to wait some time where i only see the structure of the SWF but empty! i was thinking of making other preloding for that images, but its going to be strange 2 consecutive preloding..
