ActionScript 3.0 :: Rotating Multiple Objects And Every Circle Around It
Nov 17, 2011
I have an idea of a game in my head and I wan't to get somekind of functional demo of it done in flash (CS3). I've looked everywhere but couldn't find tutorial for it, as I'm not sure what I'm looking for. I'm not that good in Actionscript. I'm now trying to describe this problem. On screen there's 4 rectangles, 2 in a row. So it's 2 rows with 2 rectangles in each. between all of them theres 4 circles. If I activate a rectangle with mouse and use arrow keys to rotate it smoothly 90 degrees, 2 nearest circles rotate with it. And same thing happens with all of the rectangles.
So I'm looking for somekind of solution where rotating an object also rotates every circle around it. and when circle rotates 90 degrees with rectangle as it's center point, it can be also rotated with another rectangle. I think I can't explain this clearly?

There is an example of what I'm trying to do [URL]. The only difference is that I'd like to use several different objects in my file...and not only one (i.e., ball or whatever) - but different objects with different shapes, colors....circulating on the same "path".

I have been working on this and thinking about it for days but I just can't seem to get it right. I want to have a circle that I can "pick up" with the mouse and then rotate (with the rotation point in the center). Currently I have done this with the following code:
PHP Code:
var radians = Math.atan2(mouseY-circle.y, mouseX-circle.x); var degrees = Math.round((radians*180/Math.PI)); circle.rotation = degrees + 90;
I have added a mouse listener for movement to the circle mc and then checked if a button was down. On button down this code would be executed on enter frame. This code works but the main problem is that I want to be able to "pick the circle up" at any angle and rotate it. If I pick it up with this code the circle automatically rotates to 90 degrees.

I try to make a looping rotating circle but I have wobbling during the rotation. It seem that the problem come from Flash. I tried manually on the timeline, by the code... but no results. I would expect a PERFECT circle! Here is an example of my result: [URl] You can download the .fla here:[URL] The circle is 2000px*2000px, center is -1000px*-1000px I believe this one also displays the problem in another way: [URL]

I need to make it so that when I click part of a circle, it'll rotate to show that bit at the bottom of the circle. I have managed to make this work for the first time you click, but beyond that it doesn't. My file is attached..

I'm currently working on a school project, where we have an arrow turning 360 degree around it's own center point. In the background there's a circle, which has been splitted up in 8 parts. The actionscript is as following:
Frame 1:
var vinkel:Number = 0;
Frame 2:
import flash.media.Sound;
stop();
//En timer der opdatere hvert 1/1000 sekund
var timer:Timer = new Timer(1);
omdr_txt.text = "Omdrejninger: " + vinkel;
[Code] .....
So it randomly turns a few rounds (usually between 2 and 3 rounds). Then when it, for instance stops at 15 degrees, or 1,05 rounds, then it will automatically go to a specific frame which has been defined for that interval (radius 0-15 for instance).

What I have is a circle image (for this purpose lets say it looks like a clock). For example: when you click 3 o'clock, the whole clock needs to rotate around with the 3 o'clock btn at the 6 o'clock position (with the pivot point in the centre). each of the 'time' positions (2 o'clock, 3 o'clock, 4 o'clock ...etc) needs to be a button and thus be able to rotate around to the 6 o'clock position. This would seem simple enough by just using a .rotate value or using tween movieclips...however the tricky part is:
The actionscript needs to determine which way the clock turns (anti/clockwise), dependant on where the clicked time-btn's position is. it needs to be some sort of if statement that says: If (3'oclock-btn) is positioned between 0 degrees (being original 12'oclock position) and 180 degrees (original 6 o'clock position), then rotate clockwise to the 6 o'clock position. If the (3o'clock btn) is positioned between 180degrees and 259 degrees (12 o'clock position), rotate anti-clockwise to the 6'oclock position.

What I'm trying to do is make a dial-type of interface, where you click on a point on the edge of a circle and that point will rotate to another point at the top of the circle. What I can't figure out is how the make "Point B" rotate to "Point A", where "Point A" is always fixed at the top of the circle and "Point B" (and Point C and Point D, etc...) are located along different points on the edge of the circle. I'm using the tween function to rotate, so what I need to figure out is how to get the difference in the rotation between the two points.

I am trying to rotate some points around the center of the circle(0,0), however I'm getting weird values from the output. I've commented the problem code..
Code:
var r:Number = 10;//radius
var y:Number;
var x:Number;
var a:Number = 90;//angle of which the semi-circle is facing.. could be a random angle.
var ax:Number;//rotated points

How to make a point rotate about the circumference of a circle upon dragging. How do I go about doing it? Is there something to do with the
startDrag(...); ?
From what I have right now, I can move the point but not on the circumference of the circle.

I am still quite new to AS. I'd like to rotate a circle (compass_mc) around its centerpoint slowly forth/back with +/- 45 degree...or better with random degree. As file size is important, I can not solve it with MotionTween. Up to this time I applied this code to the MC, which endlessly rotates it:
iranytu_mc.onEnterFrame = function(){
this._rotation+=1;
}
How to apply that sort of random slow forth/back rotation to the circle with AS?

I have a big circle with buildings all around the edge. There are two buttons that should control it. One to rotate the circle left, and one to rotate the circle right. I'd like each click of a button to rotate the circle and have it stop on a building, which then would activate an animation of the building.

So I just started using Flash CS4 from Flash 8, and I like it so far, but there's on major problem: the "classic tweens" (motion tweens) aren't rotating some of the objects I have. Like there's this flame thrower I drew, and I rotate it at the end of the motion tween, but it doesn't rotate. It will just wait till the last frame and then it will show the rotated frame. Motion works in the motion tweens, but not enlarging or rotating... why? It seems more like a glitch, because sometimes I make a classic tween and it rotates stuff just fine, but sometimes it just doesn't... what am I doing wrong here? What's going on?

I need to reassign z value to some objects that are rotating in 3d. (see attachment).
This is my code: but it doesn't work:
ActionScript Code:
for (var i:uint=0; i<container.numChildren; i++) {
cont[i]=container.getChildAt(i)
//cont[i].z=cont[i].transform.getRelativeMatrix3D(root).position.z;

Whats the 3d capability in flash cs5, I've been told there is a new 3d tool for rotating around objects. Does that mean an obj import is possible? I am eventually aiming for a series of gear wheels, one facing the screen rotating on its z axis. Is this possible.

I have two drag-related questions. The first one is how to rotate an object by clicking and holding on it, then moving the mouse round in circles. Think of a clock face, and the user clicking and holding on one of the hands, then spinning it around. The centre point would be the part of the hand that's attached to the middle of the clock face, and the other end of the hand would be able to rotate 360 degrees around the face.
The second one (and not related to the first one, a separate query altogether) is how to drag something horizontally along the screen, but have it stuck at a certain speed. So if the user tries to quickly drag the clip from left to right, it will not reach the right instantly, but instead follow the cursor at a slow speed.

All I need to do is rotate an object (which could spawn at any point along each of the four edges of the screen) so that it faces towards the centre of the screen. Obviously this will be done using the .rotationZ property. I will know the starting point of the object, and the centre point of the screen (400, 300). The object begins facing directly 'up' (e.g. if it spawned directly below the centre of the screen it would already be at the correct angle).

I'm working on putting together a game at the moment which is similar in many ways to mini golf (or crazy golf, depending on where you come from). It is shown from a side-on view and to play the user must select the ball by holding the mouse down over it, then drag the mouse to indicate the direction they wish to fire the ball in. The distance they drag the mouse (this is capped obviously) determines the power of their shot.
I am currently using a triangular object with the tip placed at the centre of the ball to show to the user the direction they have chosen. This triangle rotates to face the position of the mouse, and I'm trying to get it to extend/shorten based on the distance from the mouse to the ball. I have code in place (below) that works when the mouse is either to the left or right of the ball, but behaves rather strangely when the mouse is above or below the ball. When the mouse is in either of the latter locations, the triangle extends to be far bigger than the maximum length allowed by the program, yet a trace shows it is still within acceptable limits! I'm almost beginning to think that Flash is switching the 'width' and 'length' attributes around when the object is rotated by either 90 or -90 degrees!
The code I am using is:
[Code]....
Here's a couple of screenshots of the game as it currently stands too - please don't laugh at the horrible placeholder art: none of it is final haha (also note that I haven't implemented 'gravity' yet, so everything is sort of hovering in mid-air.) The first image shows the code working as I want it to with the triangle at it's max width, the second shows the triangle going 'huge.'

i'm using flash with box2D 2.1a. i'm rotating ball hanging on the string. The path which the rotating ball trace is ellipse. When releasing the rotating ball from the string i want the ball to fly with the obtained direction, velocity and strength. As you can see in the pictures.[URL]..I've tried to do it with setPosition (method of b2Body) and with various joints. But I haven't got the needed results.

How would i make hitTest work better with a rotating object(AS2). Becase i have a circle and it if gets near the rotating object (actually pretty far away) it starts the script,(new x and y)
I think thats the rotation script, becuase i took a break for like 4 days becuase it was irritating.

There are a couple of problems i'm having with this - the first is how to work out how to find where the tip of each sine curve is (ie the frequency) and the second is to work out how to rotate each object so that it slides sideways along the sine wave(note file is 800 x 600)here's my code: CarouselTest.as:
