Recently I came across a site showing a no. of images (probably 8 - 10) rotating around an invisible eclipse. When we put mouse-pointer over any of the images it's tip shows a linked site's name and if clicked that particular site opens up. Only one image is displayed perfectly which is on the top while rotating, while other remain blurred out not clickable. How to create such effect as I need to get it implemented.
View 1 RepliesI'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 am trying to animate the circle to follow the cursor point. Its working fine, but when you move the cursor little faster the animation struck.

I have a circle (bounding circle) offset from the centre point of my entity and I'm looking on how to move that circle around the entity as it rotates so that it's always in the same spot of the character.For example,say I have a bounding circle for the front of a car, when the car turns, that bounding circle needs to turn to So I have two points: position which is the position of the entity's centre point and offset which is the offset of the circle from that position. This assumes an angle of 0.
So if my car is facing 0 degrees: position (150, 150) and offset (50, 0) then the bounding circle would be at 200, 150.Now if I rotated the car 90 degrees, the bounding circle should be at position 150, 200.This is what I have now:
var differenceX : Number = _centre.x - _offset.x;
var differenceY : Number = _centre.y - _offset.y;
var rotatedX : Number = differenceX * Math.cos(_angle);[code]........But it's giving me these long ovals and now a perfect circle.
I am trying to move a line around in a circle, around a fixed point (not 0,0). As in the way a clock hand moves around with one end at the middle and the other end traveling in a circle. I tried the rotation function but that moves the entire object around (0,0), I need the point in the middle stationary and at a non (0,0) point.
View 9 RepliesI have a circle drawn on the screen, wherein I add a moving object. I want it to keep inside. My strategy is to calculate the circle's radius and compare it with the distance the moving object is off its center. I beleive it's the proper solution. However, I'm having a problem with letting Flash know when the running guy should stop, so he doesn't leave the circle and ruin all the fun. Here's the code I'm using (it's not working of course):
function moveTheCreaturesRightwards(event:Event)
{
if(maleMovingRight == true)
{
[Code]....
The line: rayMale.width = maleRadius.width; was added when nothing else had seemed to be working
I have an object called point that I can move around the screen with my mouse. This object has a vector mapped through it (_v1) using the center of the stage and "point"s x,y location in order to draw the vector (note all of this is working fine). My problem is occurring when I set up was a button that simply sets a value to true if you press it. The idea behind this button is that when pressed, whatever location "point" is at, it will move 1 degree clockwise in a circle around the center of the stage (this is all happening in the frameHandler so I can keep clicking the button to make it continue around the stage).
The code I am using is based in an if statement listed below:
if(clockwisePressed) {
var v1angle:Number = _v1.angle;
v1angle++; //increase the angle by 1 degree
if(v1angle>180) {
v1angle -= 360; }
[Code] .....
So what is happening here is that clockwisePressed has been set to true so this fires off. My vector (_v1) is set up to tell me the angle (already converted from radians to degrees) but it's a read-only value. So I assign it (_v1.angle) to v1angle so I can mess with it and increase it by 1 so I'm moving clockwise around the center of the stage. Then I just check to make sure that it falls into a range between -180 and 180 (if I trace _v1.angle around the stage, 0 degrees is to the left, 90 degrees is straight up, 180 degrees is to the right, and -90 is straight down). Now using the formula I derived from this thread but converted to work with 0 degrees pointing to the left and the value for Y going up the further down the stage you go, I came up with
x = centerX - radius * cos(angle)
y = centerY - radius * sin(angle)
Now when I make a sample chart on paper and use these values on my calculator, this works like a charm. If I plug in an angle, the radius, and center I get a point right on my circle I draw on a sheet of graph paper. However, when I actually try this in flash, the "point" jumps all over the stage. (Note that _v1.m is just the magnitude of the vector between the center of the stage and "point" which is the same as the radius). So I trace everything and the values for cos and sin don't seem to be coming out right. For example, if my angle is -1.9581 and I take the cos of that on my calculator I get something along the lines of 0.9994 but flash traces Math.cos(angle) to be -0.3777. Isn't using Math.cos(-1.9581) the same as putting -1.9581 into your calculator and hitting cos?
Below is the corrected code that works:
if(clockwisePressed) {
var v1RadAngle:Number = Math.atan2(_v1.vy, _v1.vx); //get angle in radians
v1RadAngle += 0.0174; //increase the angle by ~1 degree more or less
//Now just move the crosshair and get it ready to be redrawn
point.x = centerX - _v1.m * Math.cos(v1RadAngle); //_v1.m = radius
point.y = centerY - _v1.m * Math.sin(v1RadAngle);
clockwisePressed = false; //remove button pressed boolean
}
I have a circle and a big square. The circle can be moved using the keyboard. I want the square to act as an obstacle, so the circle cannot be moved into it and the circle stops when it hits it, just like a if i were to try to walk into a building. Is there an easy way to do this?
View 7 RepliesI want the final result to be a stage with a certain number of circle MC's moving around. I have made the circle MC, and added the AS so that it will start at a random point with a random color, then start moving around randomly. I want to make it so that In the beginning the document will duplicate the movie clip x amount of times, using a for loop. I want to then have all the new circles move around, and when two circles hit each other, they will dissappear, using the removeclip function. You can only use this on duplicated movieclips though, so how would i make all the circles duplicated? Is there a way to duplicate the original movieclip x amount of times then delete it? Or is there a way to remove the original after it is in a collision? Also I don't know how to do the collision detection. I am thinking of using a hittest, but would I just do it with a for loop? Is there a way so that if an MC hits any other MC?
View 3 RepliesIn AS3 is there an easy way for collisions to take place between a moving circle and a rectangle object. A moving circle has a direction and you need to know how it collides with an object rather than knowing it just hits. In .net you use a points test where you test several points around a circle to see what hits an object and then you can work out what direction it will bounce off.

View 2 RepliesI have a circle and a square on the stage. When you click on the square the circle will go to "circle._x = 300" when the circle is at 300 I want to make it when you click on the square the circle will go "circle._x = 45"
Code:
moveCircle = function () {
circle._x = 300;
if (circle._x >= 300) {
circle._x = 45;
}} square.onRelease = function() {
moveCircle();
trace(circle._x + "is the position of the circle");
}
I'm trying to implement a aabb to circle collision.
[Code]...
Somehow the collision does work as expected. Either they never move at all and "collided" was traced, or they'll continue moving and never collide when I tried swapping values around. Is there something i'm missing in my logic??? My box-box and circle-circle collision are working fine.
I was taking this tutorial, >>LINK<< I want to change it from,
Code:
on (click) {
Duplicate Movie clip to,
Code:
onClipEvent (Load) {
That way once it load's it will duplicate the circle MC a random number of times. This circle MC is inside of another MC so it wouldnt be _root i want it to goto, it would be t_mc that I want it to look for it in.
So in the t_mc MC I put this code,
Code:
onClipEvent (load) {
i = i + 1;
duplicateMovieClip (t_mc.circle, "circle" + i, i);
}
And on the circle, I put this code,
Code:
onClipEvent (load) {
scale = (random(100) + 50)
this._x = random(250);
this._y = random(150);

View 3 RepliesI have been working on a couple of projects where image scrolling have been necessary, usually along the x-axis, cause of the number of images - usually the scroll is started if you roll-over a button or something. I have solved it using a Timer, or previously setInterval, that updates the .x-property like 30 times a second or so. But in the end this method turns out to be kind of laggy, regardless of what fps I use. So I wonder if you guys could share your prefered method of scrolling
