ActionScript 2.0 :: Rotating Circle Around Its Centerpoint Slowly Forth / Back
Aug 29, 2003
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?

ok you know when on a button it may "move up" or somthing and then you get off the button and it pops righ back into place.. how do u make it move slowly and fluently back to the position.. like if you have 4 different boxes, and you click it and the arrows move to next box, but if the first box is clicked again, it will moved up to previous box smoothly back to the first box, what code do i need for this...?

I have been given the task to create something similar to the flash navigation on the link below. I have tried googling things such as "flash image rotation", "flash rotation circle", etc?[URL]

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.

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?

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 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.

I have a movieclip that I am using greensocks transformManager with so the user can rotate, skew, and scale the clip. This works fine, but I am trying to add a crop tool. If the image is rotated, when I send the image to the crop tool it measures the height of the image by the bounds of the rotated image, not the actual height of the image if it were square (re: not rotated).
So, what I tried to do what, after sending it to the crop tool, rotate it back to 0 before getting the bounds using this code:

I don't understand the math here. Shouldn't it just rotate 3rads in the positive direction to equal it out? How would I return it to 0;

how to change the 3D centerpoint dynamically? In the flash IDE you can use the 3D rotation tool and easallydrag the 3D centerpoint. You can see the new position in the transform panel.I read a lot of forums and website.. and dit some coding, but with no result.I tried to do it this way:
var pp1:PerspectiveProjection = new PerspectiveProjection();pp1.fieldOfView=35;pp1.projectionCenter = new Point(-mybitmap.width/2, -mybitmap.width/2);mybitmap.transform.perspectiveProjection = pp1;

Hi, is there anyway to access the 3d centerpoint property by code? I´m rotating some movieclips with the rotationY property but they always rotate around their center point... i wanted them to rotate around the edge to create a page-flip effect... but i cannot find the 3dcenterpoint property that it´s on the flash transform menu...

I'm developing a game atm, and I need some help on the mathematics/coding of colliding circles (and their change in x/y speed). What i need to know is how to calculate the direction and speed a circle has after colliding with a static (non-moving) circle. I know how to detect a collision between the two, but I'm not sure about the maths I need to give the circle the right speed and direction after the collision
If i do know how far away the two circle-points (in the middle of each) are to each other (in both x and y coords) would it be easy for me to find the new speed and direction of the large circle in the example above? I know that I somehow should use the angles to pretend the circle hits a flat "wall" (as it only hits one point), and then calculate the new speed/direction. My only problem is that I'm not sure how to decide the angle of this flat "wall" and how x and y speeds should change when colliding with a wall that is angled. Does anyone here have any insight, links or tips on how I can du this?
