does anyone know if there is any possibility to do simple elementwise math on bytearrays without having to program it explicitely, e.g. a built-in function for multiplying all elements of a bytearray (of type float) by a constant or adding the elements of two bytearrays (with specified datatype)?

View 0 RepliesI have been trying to emulate a drag n drop program from flash and math site dragdroptour snap to location tutorial.It uses a placed variable set at the beginning of the script and updates it with a function used elsewhere. For some reason my version of the code will not update this variable could someone tell me where I've gone wrong? I've done this before in AS and think I used globalvars but I know you cannot do this in AS3 and I'm trying not to go down that route as I know it's bad practise.Its the paper1,2,3 vars that won't update with the release to drop functions.[code]
View 5 RepliesHere is the problem:
var p:int = 0;
var n:Number = 0;
n = 32.999999999999999;
p = Math.floor(n);
trace(p); // returns 33
n = 32.11111111111111;
p = Math.floor(n);
trace(p); // returns 32
I would expect both of these to return 32. I have searched, and it seems this is an unreported bug in AS3. Or ... am I doing something wrong?
Wat is the diffrence between these two?

View 6 RepliesI have a web application developed in Adobe Flex 3 and Python 2.5 (deployed on Google App Engine). A RESTful web service has been created in Python and its results are currently in an XML format which is being read by Flex using the HttpService object.Now the main objective is to compress the XML so that there is as less a time between the HttpService send() method and result events. I looked up Python docs and managed to use zlib.compress() to compress the XML result.Then I set the HttpService result type from "xml" to "text" and tried using ByteArrays to uncompress the string back to XML. Here's where I failed. I am doing something like this:[code]Its throwing an exception at byteArray.uncompress() and says unable to uncompress the byteArray. Also when I trace the length of the byteArray it gets 0.[code]

So far the process follows top to bottom: Click button 3, image displays, everything is going well. Click button 4, and I get "Error #2044: Unhandled IOErrorEvent:. text=Error #2124: Loaded file is an unknown type." after the line "loader.loadBytes(myByeArray);" in the function button4_clickHandler. As far as I can tell I'm using everything as intended.

I can get an error-free compile if I take the seemingly unrelated TLF text box out of the equation, either by changing it to a classic text box, deleting it, or unlinking its containing MC from MyClass.
I can also get rid of the error by removing myOtherFunc()'s definition or moving it below myFunc()'s, which I had to do a few times just to convince myself that it was true.
Update: I just confirmed the same behavior on a friend's version of CS5. He's using a Mac as opposed to my Windows setup, and he only has the CS5 version installed, whereas I have both CS5 and CS4.

I narrowed the causes of an AS3 compiler error 1119 down to code that looks similar to this:
var test_inst:Number = 2.953;
trace(test_inst);
trace(test_inst.constructor);
I get the error "1119: Access of possibly undefined property constructor through a reference with static type Number." Now if I omit the variable's type, I don't get that error:

So what's the deal? I like explicitly typing variables, so is there any way to solve this error other than not providing the variable's type?
So here is a piece of code that I have seen used a lot but don't really quite understand:
myVar = Math.min(Math.max(myVar, this.min), this.max);
or some variation thereof. I understand that the function first finds the maximum value of two values then turns around and uses that to find the minimum between two values.why this is done? And how do you know when to use it?

I have created a flash program and I would like to run a second flash program from inside the first. To explain, say I am running a program that draws a circle and fills it with a color. Then, I have designed a second program that will divide a circle into sectors by entering percentages, to turn that circle into a pie chart. Is there a way to be running the "draw a circle" program and have a button that opens the "divide the circle into sectors" program in a new window and then passes information from that program to the first program. I am sure I will have to send the information from the second program to an XML file and then have the first program recieve it from the XML file (which I can do), but I don't know if I can run the second program from inside the first program.
View 1 RepliesI have created a flash 3d racing game which relies heavily on AS3's Math functions (sin, cos, tan, asin, acos, atan). It also makes heavy use of Matrix3D and Vector3D functions. The game works great on a PC, but the cars flip around and display innacurate positions on Mac computers. I know this is an issue due to the note on the Math docs page: [URL]
which states: "Note: The Math functions acos, asin, atan, atan2, cos, exp, log, pow, sin, and sqrt may result in slightly different values depending on the algorithms used by the CPU or operating system. Flash runtimes call on the CPU (or operating system if the CPU doesn't support floating point calculations) when performing the calculations for the listed functions, and results have shown slight variations depending upon the CPU or operating system in use."
how do I get this game to work on a Mac? I've tried using lookup tables and inline FastMath style approximations. But lookup tables still create the same problem, and the inline approximations I have found are not accurate enough for my game. I've also tried rounding values with floating point errors, but that has not seemed to help (in my implementation) either. I think the specific problem is with the use of Math.atan. I have not found an accurate approximation for this.. but I maybe that is not even necessary.
How do I get a random number between 0.8 and 1.2 using Math.random(); ? It would be nice if you explain.
