ActionScript 2.0 :: Flash Rotate And Drag Within Cos(_rotation) Or Sin(_rotation)?

Aug 25, 2007

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;

ActionScript 2.0 :: FMX Rotate Symbol On Transformation Point

Nov 11, 2002

I have a triangular symbol that I want to rotate on a transformation point (the pointy tip). The effect is supposed to be like Hollywood searchlights panning around (see pic below). I've done basic rotations with actionscript before, but a transformation point wasn't involved. How is this done? Is the transformation point determined manually on the stage or with actionscript?

Actionscript :: Make A MovieClip Rotate Around It's Center Point To The Left Or Right?

Jun 27, 2011

I need to make a MovieClip rotate around it's center point to the left or right depending on mouse drag. I got some basic semblance of what i want going, but it's pretty hackish. Normally i calculate the angle and such but i only really need to use the distance the mouse travels and apply it to the movieclip and for flavor add some nice easing when you let go.

public function Main()
{
var wereld:MainScreen = new MainScreen();
addChild( wereld );

ActionScript 3.0 :: Matrix Transform - Rotate Object Around External Point

Oct 14, 2010

I found the function:
rotateAroundExternalPoint(m:Matrix, x:Number, y:Number, angleDegrees:Number)
to rotate an object around an external point. The top of the object will always point at the center point which is exactly what I want.

It works fine but its possible to rotate it in an oval instead of in a perfect circle...I think it should be something with the angleDegrees Parameter but im not sure what to do with it. I also tried to set up an own matrix but I failed. Any right direction to orbit an object in an oval, and where the top of the object always point at the rotation center?

Flash :: Rotate BitmapData When Using Draw Method. Width Height Bounds Clipping / Cropping?

Jan 29, 2010

I wrote a collision detection class that works off using BitmapData.hitTest. Basically, every update, the .draw method is called and then two BitmapData's are hitTest'ed against each other to see if there is a collision.It works pretty well, however if I start rotating the source MovieClip I use for the BitmapData, the transformations don't get registered in the draw method. So what I did was pass through a Matrix in the draw method. That works. But here's the actual issue. If I output the BitmapData to a Bitmap on the stage, I see that Bitmap is, in fact, rotating, but now it's exceeding the bounds (width and height) of the BitmapData. Which is cropping / clipping the image of the source MovieClip.

UPDATE: Basically, when the Bitmap clone of the MovieClip rotates outside the positive co-ordinate space, it doesn't get drawn. It rotates outside the bounds of the BitmapData set width and height. I can multiply the bounds by 2, and then center the bitmap inside the set bounds, but then the origin point is never fixed and the object is always being moved around. Works pretty well, but makes aligning the object to any specific point impossible.Here's my isolated test code. It requires you to have a MovieClip on the stage named "iTest". I used a fairly vertical arrow shape (higher than it is wide) so I could keep track of rotations visually accentuate the clipping problem:

var rotateTimer:Timer = new Timer(10);
function rotateObject_init():void
{

ActionScript 1/2 :: Gradient To _rotation - Please Explain Trigonometry?

Oct 28, 2011

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.

ActionScript 2.0 :: Assistance With _rotation Property For Tween Class?

Feb 4, 2006

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.
