Ok, here is my problem, hard to explain tho, but i will do my best.I would like a circle picture to dissappear (or appear) with like a clockwise motion. So basically from twelve oclock i want the circle picture start going away clockwise until it comes to twelve again and the picture would be all gone by then.
View 5 Replieshow to make a counter clockwise circle using Senocular's Path class?
For example, if I start a half-circle on the left (9 o'clock) it will go to 6 o'clock then 3 o'clock. Right now it goes for 9 o'clock to 12 then 3.
Works great clockwise... but I can't get it to draw in the other direction. I tried messing with the math inside the class and it exploded!

I have a movieclip called view_mc and a button btn_rotate.
I want when the user click and drag btn_rotate button, he can rotate the view_mc movieclip clockwise and anti-clockwise.
I have written a code, but it only rotates the movieclip in clockwise direction:
stage.addEventListener(MouseEvent.MOUSE_DOWN, on_stage_down);
stage.addEventListener(MouseEvent.MOUSE_UP, on_stage_up);
function on_stage_down(e:MouseEvent):void

I'm writing a class for an instrment and one of the knobs has "snapping" values at X degrees.I have the code to make the knob snap to the set degrees,but I'm having trouble getting it to determine whether it was rotated clockwise or counter-clockwise.Here is the function that makes it rotate and "snap" The majority of the problem is because of the 0/360 and negative values that Flash has when it rotates..
In the function:
the _baseMovieClip is the clip that contains a graphic to rotate and "snap" to the degrees.
the _clipToRotate is a movie clip that actually displays the rotation
the _startAngle is the angle the user clicked on the button that triggers rotation
the _rotateObj is a sprite that is drawn when they click that I make visible to show the actual rotation when I'm debugging
the _snapLock is the degrees the knob shold rotate to (10, 15, 30, etc)

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?
i want to make one circle follow the mouse cursor, inside another circle. Similar to an eye looking at the cursor. Ive attached an example.

var xmov1 = xSpeed;
var ymov1 = ySpeed;
var xmov2 = ballRef.xSpeed;

Perhaps I'll go with a box2d equivalent instead of trying out my own physics shenanigans.
Here I what i need is : Start drawing first circle and when first circle is on half way, Start second circle.same way second and third circles. and after completing 3 circles, just gotoAndPlay 2nd Frame .
View 3 RepliesI am sure this is simple, but cannot remember how it is done. I just need to rotate an item counter clockwise 1/2 a time. The rotate option only accepts integers and when I do a motion tween it goes clockwise.
View 1 RepliesI have 2 movieclips. ro used for rotating and rect the movie that will be rotated.
I want when clicking and draging the ro movieclip clockwise or counterclockwise, the rect movieclip is rotated clockwise or counterclockwise respectively.
I allow the rect to be rotated according to mouseX and mouseY.
but it dose not work as I need.
I'd like you to show me a trick to achieve that as I want.
Here is the code:
var xPo:Number;
var yPo:Number;
ro.addEventListener(MouseEvent.MOUSE_DOWN, mouse_down)
function mouse_down(e:MouseEvent):void

I have a function that lets you click on a handle of a movieClip and rotate it. I recently updated my code to make use of Oscar Trelles DynamicMovie class so I could set a registration point in the center of the movieClip. But that has given me problems with being able to rotate the movieClip incrementally in an anti-clockwise manner.
The following code will let me rotate it clockwise, forever and ever. But I'm having a hard time wrapping my head around how to determine if the user user is dragging the mouse counterclockwise. The property mc.rotAng is set in a previous mouseDown event. It stores the previous mouse position, and the incremental angle of rotation is derived from the current mouse position and the old mouse position.

I have a simple three ring animation where the three rings fade in and out.On the stage the rings are a perfect circle, in the publish preview they look fine, but once I publish the SWF, all of the sudden the rings are not perfectly round anymore.
They are almost perfect but right at the top and bottom there is just a small portion which has sort of "flattened out"...
I bought a Flash video tutorial online for Animating and the FIRST step is to create a circle with the circle tool, and the guy does it online, and it fills itself in. I repeat his actions exactly and I cannot get the same result at all. I just get a circle.
View 5 RepliesI have two MC's, circular in shape. One of the circles is stationary and you can drag the other. I'm trying to get the moveable circle to be able to move around the circumference of the stationary circle, but not overlap. I'm able to detect when they overlap, not using hittest. I just can't figure out how to code it so that the draggable circle can't be moved over the stationary circle.

View 6 RepliesI wish to have a function that will take as input a radius value and a magnitude value.
It will return firstly a point (x,y) and also secondly a direction, (vx,vy) which will have a certain magnitude(speed).
The point returned will be a random point within the radius value and the direction will be a a (vx,xy) that moves the point perpendicular to the line segment (x,y) ->(centrepoint).
Essentially I'm just trying to rotate an object (mc) clockwise or anticlockwise depending on the value of a variable called 'angle'.If 'angle' is positive it should go anticlockwise.If 'angle' is negative it should go clockwise.
Option 1
PHP Code:
if(angle > 0) {
mc.rotation += rotateIncrement;
}

i would like spin an object in clockwise and anticlockwise direction with ease via press of a button.tried using,
on (press) {

just to get the object to turn... What i wanna do is have 4 buttons, 1st button turns the object 45 degrees, then 2nd button turns it next 45 degrees and so on... Have attached .fla of what im trying to achieve.

Is there a ready Component on the web.
I have rotated an image around 0,0 using the code below. I need the new coordinates of the corners of the rotated image.
bitmap.rotation=_angle;
UPDATE: if i rotate an image 10 deg then that moves an image 10 deg clockwise from 0,0
the bottom left corner was 0,20 and so i need to change the point (0,20) 10 deg clockwise using trig?
here is some code for a rotating crank that controls an image gallery. refer to the "image viewer stops?" thread in the flash mx forum (sorry don't know how to link to a forum yet!) for more info. attached is the fla. i want to be able to crank clockwise to scroll images forward and counterclockwise to scroll images backwards. If i keep cranking, i want the images to continue to change, if i stop cranking, i want it to stp on that image. it doesn't sem tooooo hard, i'm just numb from tryig to figure it out.
