As3 :: Flash - Moving An Object In Relation To Another?
Jan 17, 2012
i have a character_mc that moves on mouse click, a logtxt dyanamic text box and a mc named $box. The camera follows the character and when the log and $ boxes are staying put.
I want them to stay on the same point on the stage(meaning I want them to stay at the same place on the camera) I was wondering what i might do for this? I have tried to put them in a movie clip but it doesn't really seam like it worked well so i discarded the idea.
Heres the code:
package {
import flash.display.Sprite;
import flash.display.MovieClip;

I have a situation where i have relations like this:A person has one or more addresses.A customer has one or more addresses.Person,customers and addresses are separate tables.I used to do this with the @OneToMany relations.This is giving me problems since our flex client is sending me objects wich are created in the client ad have to be created in the DB.If the client sends me a person and customer which reference to the same address hibernate will create two address objects since the two address object are not the same java objects (not the same pointers).This is a problem which is caused by BlazeDS and Dozer which will create new objects when they are send to the server.So what i would like to have is the address id in the person and customer object without an relation so hibernate does not create the objects. But when i read a person object i would like to fill a transient address object based on the stored address id.

I'm building a class at the moment for transforming and scaling content with align, constrain and scaling options.
This is just just fine if the transform center is LEFT or TOP_RIGHT, or what have you, and always within the object bounds, but I haven't yet tackled situations where objects are NOT nicely aligned, or the transform point is outside of the object bounds.

I am trying to do a apply a tween for the width property on a MovieClip Object but every time it changes the width and the position too, and I don't want that. I want to change the width going to one side without changing the x and y of the object.
I tried both of thes and they gave the same result.
var c:Tween = new Tween(left, "scaleX", Strong.easeOut, 1, 1.5,20,true);
var c:Tween = new Tween(left, "width", Strong.easeOut, 20, 200,20,true);
I think it is applying the transformation according to a center of the movie clip. but I don't know how it can be changed.

I came across a problem where my flash timer keeps changing position as the browser window is resized or if the user scrolls down the page the timer will move with it?It also changes position on different monitor screens.Is there an easy way without too much code to position it at a certain position on my page :[URL]As you can see its too low and should be in line with 'Comming soon'Im also using Dreamweaver if that makes a difference.

I have very little knowledge of ActionScript. I have a movie clip. I want it to move along the x-axis when i press down on a button(button or movie clip) I do not know what code to use as it needs to be Action Script 2. Is there a Tutorial or something that can accomplish this? I have found a tutorial that moves the object around when you press a button. I am trying to get the same effect when you click down on a button: [URL] UPDATE The button is called btn and the object that moves is mctransparent I have managed the folowing:

Can I move a Flash object within the DOM without it reloading? I am developing a simple video chat application. Whenever I move a flash object within the dom tree, it resets itself. I have multiple streams which are aligned horizontally. Every stream is a different flash object. When someone enlarges a single Flash object, I need to move it to the top.
Whenever I move it to the top, that particular video resets itself, and you wait for a couple of second to get the stream back. I am currently simply prepending the same list item to the same parent. This is a very important feature and any kind of solution which doesn't require flash to reset itself is acceptable. (Except creating a parent flash container which has all the streams within it.)

I have a movieclip moving on a path by means of a tween. At the starting point a (virtual) line on the movieclip is tangent to the path. Is there an easy way to automagically rotate the movieclip such that this line remains tangent to the path throughout the tween?

I have a ball moving around the screen, position updated on ENTER_FRAME. My problem is that there is a considerable amount of flicker going on. I have thought about using something like TweenLite to move the ball but as the position is being updated frame-to-frame I don't think that will work.[code]...

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 am making a flash animation and what I want is to have different movieclips animating over the screen and randomly changing colors. The animation is not the problem but the color changing.
i got this so far:
Code:
var myTimer:Timer = new Timer(1000); // 1 second
myTimer.addEventListener(TimerEvent.TIMER, runMany);
myTimer.start();
[Code]...
Every second ALL my objects change color. But there are some movieclips that must stay the same color. So i changed the this inside the code above to some movieclip. If i tried that again, the animation of that movieclip stopt after it changed 1 time to another color.
Does any one know how i can solve this? so that the color of the movieclips will randomly change after 1 second AND the movieclips keeps their animation?

Im working on a small project and it involves a guy which you move with the arrow keys. The arrow keys add to his x, y velocities and his position is updated accordingly. How can i get this man to grab onto an object and spin around it (like when you grab pole and letting your momentum swing you around) . I can make him grab the object but I dont know how to modify his x,y speeds to simulate the arc.

Okay this is always something that's puzzled me. If I create a movieclip, place that clip on the stage, then inside that movieclip, create another movieclip, how does flash determine the coordinates of that second movieclip in relation to the stage. The reason I am asking this, is that I have a large movieclip which contains a number of other smaller movieclips. When a user clicks on one of the smaller movie clips, I need the larger movieclip to move so that the clicked movieclip is now centered on the stage.
I figure that this would be easier to know if I knew how to calculate the distance which the second, smaller movieclip is from the center of the main stage in x and y coordinate values. Am I making any sense? If not I'll try to explain again.

I need some AS2 actionscript that I can place on a button to move it to the front on rollover. and move it to the back on rollout.I have two identical buttons on a layer in my timeline. When you roll over a button a larger text box appears ontop of it. The text box is the rollover state on the button, which is a button symbol. This works great in itself, but the problem is that the buttons are place close together and when one button gets rolled over and the text box encroaches on the other button's space. I always want the text box and button you are rolling over to appear in front of the other buttons that are on that layer. But that's not possible, since one button will be in front and one will be behind. Is there some AS2 actionscript that I can place on each of the buttons to move the button you roll over to the front?

I'm new to Flash and just started working on an animated short. In one of the sequences, I realized too late that an object was too far left in the frame and needed to be moved back. Is there a way to do that in all of the keyframes at once rather than doing it one at a time? The thing that needs to be moved is a .png file, not a symbol.

i'm trying to use actionscript so i can make an object move up and down the Y axis by inputing numbers into a textbox. However at the moment my object starts in the centre and then when i enter a number it only goes down, and im not too sure how i can use negative numbers to make it travel up the y axis. I was thinking of using the numbers -10 - 10 so -10 would go down and 10 go up. Here is my code

i'm trying to use code so if i type in -10 to 10 the object will move up or down the y axis. The code i'm using at the moment calculates how far to move it from the number inputed, then it removes te object and places it in the required position. However doing the removeChild technique messes up when having many on the stage. I was wondering if anyone knew a way of calculating the rating and then using it to move the object on the stage without removing it and adding it. Here is the code i'm using to move it. OR a way in which i can remove certain objects on the stage using remove child

im having trouble getting this rotation function down pat. i have a turret that should be rotating towards another moving object. it should find the shortest direction to rotate. basically what ive done is converted action script rotation from using -1 -> -179 to 180 -> 359. but now im having issues when the object it is tracking passes over the zero degree point. the turrent then rotates around the other way. here is the code. my mind is getting a little boggled. it is being passed the x difference between the objects, and the y difference

'm putting together a flash animation of approx five productsEach picture is above the other so the flash file is tall roduct 1 at the top product 2 underneath 3 underneath that etcThe whole thing will scroll up and down vertically to display each appropriate pictureI need 5 buttons each one would move the strip of images up and down vertically to the correct location and I was wondering if this would be possible by using actionscript to move and define the position on the long strip of images.I.e when product 1 button is pressed, scroll the strip up to show product 1 picture. When product 4 button is pressed, scroll the same strip down to display product 4..For example, each button script might read something likeonRelease - scroll the image bar to y position(obviously a different position for each button)would this be feesable? I hope somebody understands what I mean, I've seen these type of flash 'portfolio' type scroll bars quite a few times but I'm not sure how to go about putting one together, is this the best way?
