I'm trying to rotate a point in my Canvas from a given point (center). In my MouseDown handler, I save the point where user click (oldPos), and in my MouseMove handler, I'm doing this:
private function onMouseMove(event:MouseEvent):void
{
// Where the user pointer right now

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 );

So 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.

So I have that panel or any other mxml component. I want somehow to rotate it around like a wheel of a car with which you drive it... loke a Racing wheel... sow like when mousebutton is down it captures pont of component... when you move mouse component rotates (not moves) according to new mouse position... How to rotate MXML component round its center like a wheel respectfully to mouse?

View 3 RepliesI'm trying to figure out how to find a point relative to the center of an object, modified by its rotation. For example, in the attached swf, I've been messing around trying to draw trails to a bitmap, coming out of the thrusters. I didn't have a problem at first, but as the ship rotated, the lines that were being drawn wouldn't remain relative.
http:[url]....
I'm sure this is because I have no idea what I'm doing, and I've just been sort of idioting my way through it. That aside, is there an easy way to find the point I'm looking for? For instance, say I want a point at Y -14 of my ship, but I want that to remain relative to the ship as it rotates.
I´d like to know if there´s a way to calculate by math the x position of point 1. There´s some coordinates at the image here attached. The "mc" movie clip is the main triangle.

View 1 RepliesI am looking to add a print job to my flash presentation. I have the basic code and can get it to print, but I have to manually set the printer to print landscape and the image is in the top left corner. If it was just for me it wouldn't be a big deal, but a lot of our presentations go to lawyers and judges so we would like to streamline their results as much as possible. Is there a way to tell it to rotate 90 degrees and center itself on the page. Below is the code I am using. I tried to use some parameters to set it for landscape, but they don't seem to work. My doc size is 720x540.[code]

I am curious abut two things... 1. Instead of a Bar at the bottom I wanna use a MC that will rotate in the center of the stage... With one half acting as a paddle, and the other side being a game over or life over side...
2. Also with the MC in the middle i want to use the arrays to make a pattern or whatnot *grid* around the middle move clip, so there is only one way to die and that is from the ball MC hittin ghte backside of the middle mc?

I have a column of objects down the center of the stage and I need them to randomly point either to the left or the right. They have been placed using a for loop so I can't point each one individually. I was told I could use Math.random to flip their scaleX position but I can't get it to work.

View 5 RepliesI am making a small tool for making simple T-Shirts designs. Everything is perfect except that I don't manage to rotate an item the way I want. I am makeing everything from ActionScript. When I load an image on the design it is added to the stage. I have an object called "ImageView" that extends MovieClip. It has some properties and some methods (ex kill() that removes the object and all associated listeners). In this object I also add the image that is loaded from a location. When I click on the item another object "Transformer" is added on the stage. It surrounds the ImageView and adds some controls for rotating and scaling the image.
My problem is when I rotate the ImageView. It rotate according to (0,0) (obviously). What I want is to be able to rotate it according to the center of the ImageView. A solution is to set the picture inside the ImageView in such a way that (0,0) is the center of the picture. But I try to avoid this since it will cause some problems (that will requiere more coding) at "TextView" (a class that has text instead of an image).
