i dont know the math to have a mc rotate around a central point by constricting to an arc..i have a circle and i want a mc to follow around the edge depending on the mouse position relative to the center of the circle...
View 2 RepliesI have four objects that when clicked needed to programatically arch back to one central point. at the moment I cna easily have them travel in a straight line, but I need all of them to rise a little (20px) as they travel to the left then drop to that centralized point.

I have a project on the go which has a compass that I would like to have move randomly around a fixed central point (giving the idea of changing direction).Would anyone be able to help me out with the coding to get this to work?

Is it possible to make a movie clip rotate about the center point of it using the ._rotation method?
View 1 RepliesI have a triangular symbol that I want to rotate on a transformation point (the pointy tip). The effect is supposed to be like Hollywood searchlights panning around (see pic below). I've done basic rotations with actionscript before, but a transformation point wasn't involved. How is this done? Is the transformation point determined manually on the stage or with actionscript?
View 1 RepliesI need to make a MovieClip rotate around it's center point to the left or right depending on mouse drag. I got some basic semblance of what i want going, but it's pretty hackish. Normally i calculate the angle and such but i only really need to use the distance the mouse travels and apply it to the movieclip and for flavor add some nice easing when you let go.
public function Main()
{
var wereld:MainScreen = new MainScreen();
addChild( wereld );

This is one of the threads that was deleted. I've come up with the same problem: how do you go about dragging an object around a fixed point (rotation)?
I can do a normal drag & drop, but with this i don't even know where to start

how to make a MC point (rotate) to where the mouse was clicked on stage ?
View 1 RepliesI found the function:
rotateAroundExternalPoint(m:Matrix, x:Number, y:Number, angleDegrees:Number)
to rotate an object around an external point. The top of the object will always point at the center point which is exactly what I want.
It works fine but its possible to rotate it in an oval instead of in a perfect circle...I think it should be something with the angleDegrees Parameter but im not sure what to do with it. I also tried to set up an own matrix but I failed. Any right direction to orbit an object in an oval, and where the top of the object always point at the rotation center?
The Rotations3DUtility is writed by myselft to make any DisplayObject rotate by its horizontal center, but the effect isn't perfect.[code]...

View 9 RepliesI'm using flash CS5.5 (trail version) and want to export a movei file out to device central to test acceleromoter settings.
When creating the file I : selected air fro andiod, made these changes to the publish settings : set upa certificate, tick all permission (as it kept telling me they hadn't been set) and then click ok.
For some reason under control > test movie > device central is greyed out. If i try to open the .swf file directly in device central it just tells me the device has the wrong version of flash.
Any ideas? I selected the file type as andriod?, preferably would like just to be able to click on test moving in device central.

I want to have two clients voice chat, I will need a central server to dish out IPs for that to work out right? Also unless I route all the streaming through the central server, won't there be problems incomming connections and peoples firewalls and such? I would ideally want to host it on a PHP shared host, could that be done?

View 1 RepliesI'm building a flash app (just AS3 with FlashDevelop) and I'm having some trouble keeping things loosely coupled around the event system. I've done a lot of reading about central event systems and static eventdispatchers but they don't quite fit the bill for me. What I'm building is similar to a video player.I have a Player class which is the parent of all the other little parts of the app.The Player class extends Sprite and I've currently designed it so that you could instantiate multiple Player's and put them on the stage.I also have a Controller class which extends EventDispatcher and I dispatch all my events through this class. It's a central event class.
The problem is that I need to pass around a reference to this class so that all the other classes can dispatch and listen through it. Passing around the reference works but it's the exact opposite of loose coupling. I know I could make a static EventDispatcher that all the classes could see but then if I had two or three Player's on the stage they would all hear each others events.How can I create a type of sandbox that will allow all the child classes of a Player instance to be aware of the central dispatcher without passing a reference or making it static?
I am using a mx:Resize effect to change the width of an image in Flex (leaving the height to look after itself) but I want the image to remain vertically centered on the page. Whilst I could calculate the aspect ratio of the photo, and work out the new y value to keep it centred, I would have to include a mx: Move effect too, and I am hopful that Flex has a simpler way. This is for a photo gallery where images are loaded at run-time, and swapped about.
So I really would like to avoid recalculating the aspect ratio and vertical position every time the updateComplete event fires, I tried putting my image inside a mx: VBox with verticalAlign="middle", thinking that the box would do all the centering for me, but this only seems to happen when the app first starts - i need it to gradually adjust the position during the period where the effect plays (to keep it central even when part-way through).
Here's a stripped-down example (which doesn't work):
<mx:Application xmlns:mx="[URL]" layout="absolute" width="600" height="600">
<mx:Resize id="fxResize" target="{imgPhotoA}" widthTo="350" duration="500" />
<mx:Button x="10" y="10" label="Resize" click="fxResize.play()" />
<mx:VBox id="boxPhotoA" x="100" y="20" height="500" width="350" verticalAlign="middle" borderStyle="solid" verticalScrollPolicy="off" horizontalScrollPolicy="off">
<mx:Image id="imgPhotoA" width="60" maintainAspectRatio="true" source="[URL]"/>
</mx:VBox></mx:Application>
I am having some dificulty making a path for this enemy i'm trying to create... cause i want him to rotate + move, then stop, then shoot, then rotate back and move off screen... Its easier if you see it.. you can download the swf file in the zipped archive to demonstrate what i mean. I did it there with tweens. Anyway.. i tried and make it but i'm a little stuck on the stopping part... you can also see what i did in the fla file attatched...

What am i doing wrong?
It's been a long time since I've done any work with actionscript, and alas I've forgotten nearly everything. I've tried to look for a tutorial that would explain basic animation with actionscript, but the one that I found on Kirupa was no longer there.
Basically I'd like to do this:On the stage I have a movieclip and I'd like the movieclip to move along the x-axis to a certain point and then back to the starting point again. The moving speed of the movieclip should also be adjustable.
I'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points.
A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.
How to convert 3d point to 2d point? I've found next formula in Internet(camera is situated in origin)
[Code]....
But these formulae give me strange result when z are less than zero(z<0) I need build line from A(100,100,100) to B (100,100;-100) As you can see these equations give really strange result when I try to convert B point in 2D dimension
i have the follow issue :
I have a point which is setted at the border on a component, with changed transform point to the center of a component in order to match the component rotation.
the important part is when i try to get the point XY after rotation - they remains the same as before rotation.
how to get XY, after rotation ( changeing point.rotation property to specific degrees of rotaion )
I am using AS2 with Flash 8 Professional So, my problem is that I currently have a man in the middle of the screen, who shoots a line towards the mouse when I click. However, when I use hitTest to see if the line collides with another object, Flash recognizes the line as a large box if it is diagonal, so the hitTest isn't very accurate. The line only satys there for one frame, so I can't have the usual moving-bullet-style. I am either looking for a way to create an imaginary line with AS from the starting point to the mouse and beyond, and tell whether or not this line intersects with an object... or some other way that I haven't thought of to fix my problem. Keep in mind that the line rotates from a center point towards anywhere around it for 360 degrees.
