I have a TextArea named TextView. The following is my code:
TextView.textFlow = TextFlowUtil.importFromString("if (i < 36)");
when trying to implement this line of code, I get the error:
[Fault] exception, information = TypeError: Error # 1090:

Here 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 2 RepliesI have a code in which I have to use Math.round if a certain value is for example 3.67 (67 is higher than 50) and Math.ceil if a value is for example 3.23 (23 is lower than 50). What can I do to make flash calculate if what after the dot �.� in 3.23 (for example) is higher than 50?
View 2 RepliesIn TextArea with id="TextView" the loaded html-text length is 1080 lines. This process takes 3-4 seconds and would be desirable to indicate this to the user.
TextView.textFlow = TextFlowUtil.importFromString(data.readUTFBytes(data.bytesAvailable), WhiteSpaceCollapse.PRESERVE);
I think the delay in TextFlowUtil is in the process of converting a large number of tags (e.g., <span>). Are there any progress or completion events to hook?
I am having issue with my created flash, it can't handle chinese characters? is there some way i can handle this thru code? or should there be any font or language pack installed
View 3 Replies1) Each field in the form only allows 3 characters and no special characters such as @ _ ! . , etc... 2) When the user goes to the next field in the form, the previous field appears blank but the when clicking on that again, the original text appears. 3) When submitting the form, it just keeps saying "in progress" and never shows the confirmation text nor does the email get sent. There is an HTML file included with this form but I am not sure if I need to put that in as I have embedded this form into an SWF file so I don't think I need that code but let me know if I am wrong about this. I am posting both the AS code and PHP code below..

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?

View 3 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.

here's where all you math genius' get to help me out. I know that this principal is not difficult and was taught sometime during my highschool years.I need a math formula which reduces the ratio of any x:y to the smallest quanity possible. Basicaly so that the smaller of the two numbers is 1 and the other number is whatever it would be, compared to 1... but, I need it to work for both posative and negative numbers.(I'm the ultimate Math newb.. bear with me)
so. I have x=20, y=20 is 1:1
-20, y=-10 is -2:-1
x=10, y=-5 is 2:-1
ect.
so what is the formula for that?
Envrironment: Flash CS3, AS3 I have a horizontal image scrolling project that I am working on, and it works but is not super smooth, I would like it to be smoother when it scrolls, and realize that this is a function of pixels scrolled over time and the FPS of the document.
Right now I am moving the items 1 pixel at a time on a timer with delay of 8 to get it to scroll at the speed I want. I am moving it at 1 pixel in order to catch exactly when an object should wraparound to the beginning of the scroller to show up again. So I don't know that I can really change the number of pixels moved to more than 1 and still have the images spaced perfectly, which makes me think I need to increase or decrease the FPS and or the timer delay to make it scroll smoother. Right now it is at 30FPS and as mentioned the timer delay is 8. Small changes to the delay is not a problem.
This is one aspect of flash i don't fully understand. I would really like to know how to figure this out so I can apply it to future projects as well without doing trial and error to make it smooth. Can it be function, like a way to figure out I need to move a 120pixel picture 60 pixels in 2 seconds, what should my FPS be and the picture size and movement size and number of seconds can be variables?
this math isn't working well. I'm using it for a rotated drag and drop (of a tone arm on a vinyl, a kind of abstract turntable simulation). Right now it just moves a bit in the middle of the vinyl (values between 21 and 36, is this degree or what unit is this?), but it should move between the two edges. The problem is that I don't know enough about trigonometry functions. Therefore I can't optimize the math for envisaged behaviour. Does anybody have an idea/tip how I can get a bit more control on the math and its effect? (maybe with more trace functions)

Set variable as numbers
var monthly_num:Number = 0;
var ttl_num:Number = 0;
var ttl_rev_num:Number = 0;
// user-entered numbers from an Input textfields
monthly_num = monthly_txt.text;
ttl_num = ttl_txt.text;
// Multiply two user-entered number together to get new result
ttl_rev_num = ttl_num*monthly_num;
Attempts to assign numbers typed into textfields to numeric variables causes errors.

View 3 RepliesI'm starting a project for browsers which requires some complex data processing. The algorithm I'm using is 50-100x faster when accelerated with GPU.
I could use JavaScript, Flash or other technologies with the browser.Is there any way I can access the GPU to accelerate the processing of my math?
Some computationally intensive software are now using the GPU to solve mathematical problems. Now that flash has GPU support, is it possible to use flash to crunch math problems? How would it be done. In other words, does flash expose sufficient low level API to control the behavior of the GPU sufficiently to perform such a task?

I think I broke my Flash. I'm using Flash CS5.5, and when I use AS3, any references to the Math class give me errors like this:1061: Call to a possibly undefined method sqrt through a reference with static type Class.1061: Call to a possibly undefined method pow through a reference with static type Class.1061: Call to a possibly undefined method pow through a reference with static type Class.The code in error is this:var dist:Number = Math.sqrt(Math.pow(initPos.x - pos.x, 2) + Math.pow(initPos.y - pos.y, 2));What the heck is going on here? Math is a top-level class, so I don't think I should be getting an error like this. Is it possible to somehow "break" the Math class? If so, how do I fix it?

View 1 RepliesI have an app (historical timeline) in which I am using one object (driver) to scroll another (driven) - like a scrollbox.There are limits on the movement of the driver, so I am using the % of the driver's movement to drive the % of the driven object's movement. It works fine on the ends of the driven, but I need to distribute the movement so that the driven object moves more at the end than at the beginning.Basically I need to multiply the % so that it moves from 0 - 1 non linearly.
