Code:
function rtd (rad) {
return rad*(180/Math.PI)
}
trace(rtd(Math.atan2(0,10))) //supposed to be 90 degrees but it return 0
trace(rtd(Math.atan2(-10,0))) // supposed to be 180 but it also return 0
what to do?
I've got a movieclip which follows a predefined path (like in those tower defense games). Normally the mc changes the direction it faces with Math.atan2 method and then rotates the movieclip, but because this game is in a tilted view( in stead of directly from the top) I need it to change the frame in the MC according to the direction it's facing.
Is it possible to read out Math.atan2 method data, and then change the frame the MC is displaying, according to this data? I used [URl]...on-and-realism as a base for this game. If Math.atan2 method
wat's the difference between finding a angle using Math.atan2(y,x) function and by finding using the movie clip's rotation (mc._rotation*Math.PI/180);
View 9 RepliesSo let's begin. I want to build a wheel which you can spin, similar to a roulette wheel. You can do this both ways (CW and CCW, this issue causing the bug, actually). The wheel has some acceleration to it too, and I achieve this by measuring the start and final angle of the drag movement, using Math.atan2(dy, dx). The problem is the following: atan2 outputs the following angle scheme, assuming the point relative to which the math is done is in the center of the circle.
atan2 returns a value measured in radians, so I'm using the classic angle*180/Math.PI formula. I've changed this original scheme into the following, using some simple math to shift the angles a bit, to resemble more accurate circle angles (going up to 360 degrees) The problem that I'm facing at the moment is should the user decide he wants to swipe clockwise, and moves through the right point, where 0 turns into 360 or 180 turns into -180, the whole angle difference thing is capsized. It registers a CCW movement (as if the user swiped his mouse all around the circle). So, I'm looking for some ideas as to how I can work around this small issue.
i have a problem with Math.random().here is part of the code:

Sometimes I get a decimal return. Then, when I close it,and run it again, it shows the correct answer.
I'm new to Actionscript programming. I'm trying to figure out what is the best way to return multiple variables, each having a different data type, from a function. For example, if a function needs to return variable aa ( a string) and variable bb (a number).
The function I'm using just crunches a lot of math, and doesn't relate to an object in a GUI. One method I got from a Google search used an Object, but as (I think) this requires me to create a class, I wondered if there was a simpler way. Since an array can hold elements of different data types, perhaps this is a simpler approach (?). [code]...
Here is my formula, Not getting the right output.... I am looking for the monthly payment someone would have to contribute (with a rate of return %) to get their "Future Value"!! I am doing something wrong.. I believe it is really simple..

Is there a way to reverse Math.atan2 back into a dy,dx value? like dx =5 dy = 3 Math.atan2(dy,dx) then much later after dx and dy are released is there a way to get the dx dy values... hopefully that made sense...I have a cold and the medicine is messing with my head
View 2 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?

I am trying to get input from my Arduino to Flash, Flash gets signals like this: [where each number seperated by a - at the end, stands for the input of a sensor]

Code to convert this text to values in an array, using regular expressions [totally new for me] that would convert the data to:
0: 0,0,0,0,0,400,0,0,0,20,0,0,0,0,0,65
1: 0,0,800,0,0,0,0,0,0,0,0,0,0,0,0,0
2: 0,0,0,0,0,0,0,0,100,0,0,0,0,50,0
which is traced by this line: trace(dataId + ': ' + dataArray);
So dataId can change from 0 to 2, and dataArray contains multiple (integer) values
Friday, this worked perfect. But for some weird reason, it stopped working properly: it looks like it merges lines when it shouldn't:

As you can see, the first line, is working fine: 16 values
the 2nd line contains 33 values: the 16 values supposed to come after the 2:, but after that 16th value, a linebreak is missing, and the 0: is displayed as a 0, and adding his 16 values behind it. The same goes for line 3: 1: 16 values,2,16 values,0,16 values
the next line only merges 1: and 2:

I'm creating game in which user is given a map and five flags. User must drag flags, one by one to the countries, so after creating MovieClips that represent flags, I started creating code for them. That worked for France, but after I copied it to Germany and changed everything using CTRL+F ('france' to 'germany' and 'France' to 'Germany') it didn't. Well, actually it did, but there is some error. That's funny, coz German flag does absolutely everything it should, and still there is an error in the output. Here, that's the code:

I'm very close to achieving the desired effect, however, i have been stopped dead in my tracks. I Used Pom's Real/Fake Mask Drag tutorial, so I have that set, however, my problem is getting the ripples to mask...

(oh, btw...the ripple MC is dragged by the mouse, so the ripples follow the mouse. I saw an effect like this, a looooong time ago, probly in the days of Flash 3, and i was curious how to go about it, so I have been trying for the last few weeks...)

View 5 RepliesI encountered a rather irritating problem yesterday. I wrote a class. The class has got 1 variable of the type :Array. its a public variable.On the scene i have 2 movieclips which are connected to my class through its linkage in the library.My problem is that even though the instance-variable (the array) is supposed to be unique for the instance only it gets overwritten for every new instance i create.for example. if i assign the first instance's array 2 values (1, 1)and the do the same with the second but here i change the values to (2,2) then when i check my first instance it has got the same values as the second instance...that is (2,2).

Whats up with the problems when you let a different MC control the drag of an MC. (ie. press this mc, this other mc drags).Take this FLA for example. Notice the trace will pop up sometimes, if you get the box at a very certain position on the temp MC.
