I'm having a problem determining if the angle created between two movie clips (which I've calculated with Math.atan2) is within +/-35 degrees of movie clip b's rotation.

I have a project which will allow the user to upload an image, drag it within a certain area, and rotate it.The trouble is, that the user is allowed to rotate the image. When they do, then because the area is defined by the width of the rotated image, then the image will not go as far as it's boundary,or it will cross over it's boundary.I have searched the web for a solution, and have found nothing.I am currently thinking it has something to do with Math.cos() or Math.sin()Here is my current code(which doesn't work):
r = mc._rotation;
mc._rotation = 0;
w = mc.clip._width;
h = mc.clip._height;
[code]....
Ive made this rotation with AS. But Id like to make the bar to move from angle A to angle B smoothly.
How can I do this?
I am trying to make my character look as he is walking around on the stage. I can make him, but what do I to make move his arms and legs? Also, I want the character walking animation when one of the keys is pressed, and stop walking when that same key is released. I have looked and looked with google and I can't seem to find the answer
View 3 Repliesfor examlple i have box. height=16 and widht=100 the problem is when i apply rotation on that movie clip it changes its height and widht. is there any way to control that? or any one can tell me using what formula it reduce the height and widht when we apply rotation on it??

onClipEvent(enterFrame) {

this way it only flips to another degree, but you can't see it go round...
From what I have gathered, _rotation uses radians?Basically, my initial goal was to make a movieclip rotate towards the mouse. I'm not very good at trigonometry.Using the help files I found atan2 which seemed to be what I needed. A little fiddling got me to this code:
var xDist:Number;
var yDist:Number;
var angle:Number;
onMouseMove = function () {
[code].....
However,the _rotation is opposite what is expected. This is not a problem as I can just flip the movieclip. But really what im here to ask is, please ecplain this code for me? I don't correctly understand how atan2 works.. and why it needs to be *60.Basically: How to get a movieclip to rotate towards the mouse.. and why does the code work, I want to learn trigonometry.
Is it possible to make a movie clip rotate about the center point of it using the ._rotation method?

Which is currently very glitchy it will not look at the mouse directly instead it will just continuosly rotate trying to find it, is there any way to fix this? The game... I have tried several different methods... Is it because it does not know how to face the mouse and what part of him to use to face it, if so how can i fix it?
if there is a way to use the _rotation property with the Tweening class to make a movie clip continually to rotate from it's current position instead of starting back at the original position and doing the same rotation again.
I'm trying to make an movie object rotate 90 degrees by clicking on a button and then when you click the button again, the movie rotates 90 more degrees. I don't want it to start over and do that same 90 degree rotation with the Tween class.
how do i change an object's _rotation based on the xy coordinates of another object (so it is facing it)?

I found the tutorial on duplicating movieclips, especially the line-by-line translation of the code. how to communicate with those clips�specifically to make them draggable and also to change the _rotation with Key.Right, Key.Left.

It does'nt need any navigation like this example, but it's going to just an animationmovie.This animation is going to be viewed on a widescreen tv. How do I make the animation fit the screen? I'm not sure which resolution the animation must be. I guess this has to match the resolution of the tv. But is it just as simple as changing the flash file settings in 1920 x 1080?

I am rotating an object by incrementing in 90 degrees,however after 180degrees it rotates to -90...then it can't quite make it's mind up if it should go to -180, or 0, which should be the same thing? (except it messes up my if statements down the line)(by that I mean, sometimes it will go back to 0, and sometimes it will switch to -180??)Where is 270, and for that case, 360?
View 2 RepliesI have a program which must convert degrees to radians every frame and use this value to change a variable. After a while, I notice that the variable becomes way different than what it should be, because of the slight inaccuracy when converting degrees to radians (I multiply to value by pi/180). I was wondering if there is a more accurate way to convert or maybe a way to use Math.cos() and Math.sin() with degrees.
View 4 RepliesI'm having trouble with this mainly because Flash's Math.atan() doesn't give the same results as my TI-83's tan^-1 function.
If I have a line with a positive rise and run for the slope and use tan^-1( (the slope) ) on my calculator, I get a value between 0 and 90, with 0 being a horizontal line and 90 a vertical line. A negative numerator with a negative denominator for the slope puts it in quadrant 4 where tan^-1(slope) gives 0 to -90 values, again with 0 being horizontal and -90 being vertical.
Putting the slope of the blue line into tan^-1() would give a value of about 80 degrees, while the red line would calculate to about -50 degrees. The rotation property Flash uses rotates objects clockwise and can range from 0-360. Using the -90 to 90 values and figuring out if the rise and run of the slope are positive or negative, I can determine which quadrant the line is in and calculate the degrees.
However, this so far is not possible for me because Math.atan() gives odd results.
A practical application for this knowledge would be a player in a game throwing spears from (0,0) to the mouse x,y. The slope would take care of the trajectory of the spears, however if your spear sprite is a spear flat and facing toward the right, you need to rotate it appropriately from 0-360.
I need to get a certain object to rotate by set degrees (my navigation for this project is organized on a wheel--6 sections on the wheel), and I would like to have buttons that tell this object to smoothly rotate by set degrees (intervals of 60 degrees in this case).
What I have in mind are 5 buttons that control the rotation:
1. 120 deg. ClockWise
2. 60 CW
3. 60 CCW
4. 120 CCW
5. 180 CCW
I've created some code that rotates an arrow up or down when the user clicks on it, depending on whether the timeline is on frame 1 or 5. The problem I am encountering is that rather than rotating visually, it just flips to the correct degree (in this case, 0 or 180).
Code:
function turndown():Void{
for(i=0; i<16; i++){
this.upDownMC._rotation += 11.25;
}} function turnup():Void{

I am using Senocular transform tool and I have an object on the stage which I can rotate freely using the mouse. What I want to do is "capture" the total degrees I am rotating the object and write in a a text box. For example, if I will rotate the object clockwise 3 times, the text box will show 1080 (360 * 3), if I will rotate the object counter clockwise 1.5 times the text box will show -540 (360 * -1.5).
