ActionScript 3.0 :: Flash Rotate Around Center Of Object?
Aug 9, 2010
I 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).

I'm using CS3 with ActionScript 3.0. What I want is simple, and I've done some searching but nothing that can get me the right results.I'm going to post a link that does exactly what I want: http:[url]......This rotates the circular object around a center point in a way that you can distort the object yet is still remains turning in a circular motion. A simple motion tween rotating the image will only work if the object is perfectly round, so distorting the object to make it more straight or curved won't work with a simple tween. I want to do exactly what is happening here (with my own object), is there some AS3 behind the scenes here making this turn on a center point?

I'm not the swiftest when it comes to math, but usually I can figure out through trial & error how to modify AS. For the life of me I can not figure out where this AS gets it clockwise rotation, so that I can change it to counterclockwise.
Code:
onClipEvent(load){
this.rotation_speed = 2;
function origin(){

Im working on a racegame Actionscript 3. When the car is moving I want it to rotate the wheels. The problem is, is that I have 2 movie clips in 1 movieclip (front wheel and backwheel). Is there a way to code 2 center rotate points?

I am using the following script in AS3 in order to rotate an MC around its center:[code]Works great, only rather than a CLICK, I would like the mouse to cause the MC to rotate in response to the mouse's movement up and down the y-axis of the MC I want to rotate. How can I write a script so that the mouse location in relation to the y-axis of a specific MC will trigger something?

I 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 round movieclip ( like a ring or clock ) and i want to press and drag it to rotate it around it's center ( AS3 ). I tried hundreds of ways but none of them works perfectly. I think i miss something in trigonometry and flash's rotation concept.

I have an object that points in the direction of another object (i.e. it rotates to the direction that the second objects x and y coordinates are at) below is the code I use.
var distx = target.x - x;
var disty = target.y - y;
var angle:Number = Math.atan2(disty, distx);
[code]....
as you can see. Not only does it rotate towards the target object, but it also moves towards it too. When I play the movie, the object instantly points to the targeted object and moves towards it. I would like for it to slowly turn towards the object instead of instantly turning towards it.

I've got this simple code here:
this["recipe"+i] = new recipelistname();
this["recipe"+i].buttonMode = true;
this["recipe"+i].recipeid = i;
[Code]....
The problem is that the movieclip rotates around the center. The textfield inside the movieclip is starting at 0,0. But it still rotates around the center, how can I make it rotate at 0,0?

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 );

I've created an mc which functions as my map and controls to go with that which allow the map to be moved around and key points navigated to and zoomed in on at varying zoom levels.I'm using scaleX and scaleY to scale the map mc and a list of x and y positions to correctly position the map for each key point.When I want to go to a certain area I perform this calculation (offsetX and offsetY are the center of the screen):
newX = posX * scale + offsetX;
newY = posY * scale + offsetY;
Then I tween the position and scale of the map to smoothly scale and move the map to the correct position:
var tween = new TweenLite(_background, EASING_SPEED, {x:newX, y:newY,scaleX:scale.getScale(),scaleY:scale,ease:EASING_TYPE,onComplete:moveToComplete,onCompleteParams:[room]});
I now need to implement a zoom in / out function and this is what I'm struggling with. The zoom should use the center of the screen as the reg point for the scale, so I've been trying something along the lines of the following to get the correct positioning:
var newX = offsetX - (offsetX - _background.x) * scale;
var newY = offsetY - (offsetY - _background.y) * scale;
So in my mind this gets the distance from the current position of the map relative to the center point of the screen (offsetX, offsetY) then scales that distance by the new scale. However, this is clearly wrong because it's not working and the positioning of the map is wrong.I've also tried using a transform matrix to get the correct values but I know even less about them and not got the right results.
function scale(target:MovieClip, center:Point, scale:Number):Point {
var m:Matrix = new Matrix();
m.translate(-center.x, -center.y);//move the center into (0,0)

When you create shape on stage and right click and chose create object you can chose Registration point for the object..you chose what corner will be used as center of coordinates for this object. Now onice you create object is there way to change this registration point e.g. i created it in center now i want to to be in upper left corner?

I am working on a car game in flash where you see the car from a top view and you go straight ahead all the time on an endless road.
The game so far is built in the way that I have a image of a car that's the main car and the road is a image itself that keep switching with another image of the road and when you play it it looks like the car is moving very fast. But actually the car is not moving at all except for when you move it yourself by going right or left.
When turning right I do not want the car to simply move to the right, but I also want it to rotate a bit so it looks more realistic when turning.[code]...

I have a project I'm working on that requires a box to be rotated aropund an offset axis by dragging a button in one corner of the box. Most of the scripting for this works great, but there are a few things I can't work out. The box is limited to an up and down position (0 degrees and 90 degrees respectively). This is what I want to happen � when the user drags the box from the up position and releases somewhere between 10 and 80 degrees, the box continues down to the end down position on its own. If it begins on the down position and is released midway, it continues up. For some mathematical reason, my version likes to orient around 50 degrees.
