How do you get all the points that are on a circle?
I've already tried a for loop using the equation x^2 + y^2 = r^2 but so far it doesn't seem to be working...
I'd like to find out how because I want to place MCs dynamically on a random point that is outside a certain mc.
I need to position objects equally spaced, on the perimeter of a circle. Question is: How can i find the points on the circle based on the number of objects i need to position, and how can i translate these points into another movieclip's coordinates? i thought to make a loop, and for each object (based on it's index in the loop) create a line from the center of the circle with a degree of 360/loop length * object index, and find the point where this line crosses the circle's perimeter.
I dont know though, how to actually implement my idea, i dont know the whole 'finding points' area etc, and I am not at all sure that my idea is the most light and effective solution. This thing i'd like to do (i think) is quite a common task, if you want a circular menu, or whatever, but i havent found anything anywhere around that could shed some light...
I can do it on pen and paper using a compass, but can't do it in Actionscript 3.As the title says, essentially I need to find the centre of a circle using multiple points from the radius.
View 1 RepliesI'm having issues with drawing a circle. The code seems to work for drawing all the required segments except one, but tracing the points of the drawing looks correct.This is the class that generates the segments:

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.

View 4 RepliesI want to create circle, and put 8 points on it. So, user can drag each point in order to change it's shape.
Is there any way to do this in flash?
I have some following code:

So, can anyone convert these three point curve line to 8 points circle?

View 0 RepliesTrying to do circle circle collisions via math which I'm really having trouble with. One circle (player) just moves from keyboard. The ball reacts to the player. All the code shown is in my players class and I passed in a reference to the ball.
On my enterframe I have:
Code:
var xmov1 = xSpeed;
var ymov1 = ySpeed;
var xmov2 = ballRef.xSpeed;
var ymov2 = ballRef.ySpeed;

Perhaps I'll go with a box2d equivalent instead of trying out my own physics shenanigans.
I have been tasked with trying to create a drawing tool that draws dotted lines as you drag the mouse across the stage. I can easily capture the points on MouseEvent.MOUSE_MOVE and store them in a vector and then draw the points as dots:
The problem is that I need to calculate evenly distributed points on an ever growing Vector of points so I can only draw the line between say every 5th point (say using modulus). I have been battling away with Bezier curve equations both Quadratic and Cubic but still can't quite figure out how to convert my Vector of points into an evenly distributed Vector of Points without sucking the life from the CPU.
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 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.

I am trying to create a mindmap where the user can drag points about the screen. I have gotten as far as drawing the line via actionscript, and drag+drop the points (defined as movie clips on stage). This is the existing script - I don't know how to get the lines to follow the points. Something to do with ENTER_FRAME or updateAfterEvent?
var line:MovieClip = new MovieClip();
line.graphics.lineStyle(1,1);
line.graphics.moveTo(ptOne.x,ptOne.y);

I am following a good tutorial here:URl...And it uses the following example file to display an embedded FLV movie:URL...I am having a problem editing the cue points. If I open the compenent inspector for the FLVPlayback, and then open the cuePoints dialog, I should be able to add, remove, or modify cue points. However, I can't edit anything in the dialog at all. It seems locked.The tutorial clearly states you should be able to edit the points.
View 1 Replies[URL]In the tutorial, it says I should be able to edit cue points for the FLV video. I open the component inspector and the cuePoints dialog. All the cue points are listed, but it won't let me edit them. They seem ti be locked. I need to be able to edit cuepoints within flash for a linked flv file.
