ActionScript 2.0 :: Moving Circle To X Position When User Click On Square
Jun 18, 2008
I 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 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?
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`m working on a app that you can draw lines.....like circles, rectangles... my problem is when a user draw a circle for example....i wanna be able to paint (change color) inside of this circle. I`ve tried working on Shapes with cacheAsBitmap = true and Bitmaps with BitmapData but it doesn`t seens to work.
i would like to know when a circle hits a square.Following code returns true when the rectangle of the MovieClip (blue) hits the square and not the circle itself:
circle.hitTestObject(square);
In as2 you had an extra parameter to indicate that.
I want to build a specifik thing in flash, and don't really know where to start.... Say I have:
3 images of 3 three different squares
3 images of 3 three different triangles
3 images of 3 three different circles
The first thing you see is Square 1, Triangle 1 and Circle 1. If you were to click on Choose Square, Square 2 will appare in Square 1s place. If you click on it one more time, Square 3 will appare, and then round again to Square 1. Same thing for all the shapes.When you're satisfied with your selection of shapes you click OK and then you get to see a movie, based on whatever choices you've made. Because there are 3 different shapes and 3 different objects within each category, there will be 9 different movies to watch (3x3=9).One example of how this could turn out is:
I have a square object in the middle of circle.and i can move square object using up, down, left, riht arrow keys. I need script for when square object touches circle, then it goes to back, I have use for this below code :
var myobjdim:Array=new Array;[code].....
In above code "myobjdim" is square object and "bg1" is circle object..
-Take a circle and place it in the center of a square scene.
-Make a rectangle and snap its left edge to the circle's center.
-Make another rectangle and snap its left edge to the right edge of the first rectangle.
How would you make it so movement doesn't happen at the registration point but on the whole arm. Say i ran a rotation script on the upper arm with +=1 and the lower arm with +=2. How would you place the parts, what format would they be converted to and what would the script format be. Multiple methods would be welcome of course!
When I mouseover the square and it expands and when I mouseout the square it should shrink back to its original position. The expandSquare works but the shrinkSquare doesn't.[code]
I'm trying to make a basic flash calculator except it only has to be able to square the number provided by the user, I have followed many tutorials but I keep getting the NaN as the output. Here is the actionscript:
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.
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.
I 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 a square movieclip named squarepad. What I want is when I click on it to do [some stuff] according to where the square is clicked. It should be something like this: if ([mouseclickedx] > 1) and ([mmouseclickedx] < 10) then [do this] end if
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 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?
In 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.
I'm not so hot with this type of math.I'm trying to duplicate and position a movieclip (not animate around circle just place) around the circumference of a circle.The part I'm having a hitch with is respecting the movieclip's angle.I'm setting the movieclip's registration point at the bottom center.
I am trying to animate a circle from a position to another, but the speed is like "easeIn" twining animation. The moving speed start high and ending a smooth slow animation like easing. I know It can be done thru easing. but its not helping to my animation which i am doing currently. So pls someone help to do this by "EnterFrame" event.
Circle starting position : 10 px Cricle Ending position : 500 px Starting Speed : 20px /per sec Ending Speed : 1 px / per sec
So what will be the speed in middle of somewhere ?
I'm trying to move an object along circlular motion guide dynamically using two buttons -- a left button, when pressed down, will move the object counter clockwise, and the right button clockwise.
I'm trying to create a flash app which creates and positions circles around the circumference of a circle. My issue is that my grasp of trigonometry is flimsy at best and I'm struggling to create the code.
Here is what I have so far (Called rotation matrix, because that's eventually what I will be using on it):
ActionScript Code: package com { import flash.display.MovieClip; import flash.display.Sprite;
What I'm doing is taking an image and "folding" it into a cylinder. I am then placing smaller images at certain points in front of that image. The large image isn't big enough to make a decent-sized cylinder, so I had to use it twice, which is fine. So now I need to create doubles of every small image that goes in and place them at opposite points (from the top perspective) in the cylinder.
Here's my problem: I want my inputs to be a simply x and y representing where the object would be if it were overtop of the flat large image. I take those inputs and (attempt) to convert the x coordinate into an angle, with which I can calculate the object's x and z position, as well as its y-rotation. However, my input range seems to be much more limited than it should be. The problem seems to lie in my angle calculation, since the others are pretty standard. Here's what I'm using right now:
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'm working on a project for a client, they want a simple drawing api which requests the user to draw a circle, or a shape on screen. The circle is then analyzed and a Score/Percentage of correction is returned. The drawing I have covered, how to assess the drawn circle against a perfect circle?
My first idea was to put invisible trigger points around the circumference of the shape and check for hit tests when the user is drawing. Another would be to track the dimensions of the left, right, top and bottom most bounding box and then find the radius, or something to that effect.
If I have several items that move across the screen but the user can click any of them at any time, how do I record the current position of any of the items item in order to use that data to change the position of the item after the user clicks?
This is what I am doing: I have 11 images that slide accross the screen. The user can click any of them at any time. When he clicks one I am scaling the image so it looks like it is comming forward (z axis) and then the rest of the images are scaled down so it looks like they are going back on z axis. So what I am trying to do is get the current position of the image when the user clicks the image so that I can use that to correctly estimate the scaling and moving of the image to make it look like it scales from the center and not from the top left corner. So if have a variable that gets the current position of the image being clicked I'm thinking I can change its position using something like: x = currentposition + -45;
I'm trying to find a random x,y value that always is at the far end of a circle. Like if the circle has a diameter of 300 pixels and the centerpoint is at 50,50, I want a random position on the outskirts of that circle. Just cant seem to do it.
