The 3D rotation properties (rotationX, rotationY, rotationZ) all revolve around the objects registration point. Is there any trick to change where the rotation center is?

Is it possible to make a movie clip rotate about the center point of it using the ._rotation method?

View 2 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?

View 9 RepliesI have developed a flash app in AS3 that allows you to drag objects around on stage, save,and load them. When the "save" button is pressed, it then loops through each item on the stage and gets the coordinates (x and y) for the bottom left corner and the top right corner. Code:

var bottomLeft:Point = new Point(-50, -50);

How is it possible to access another movieclip inside a movieclip, if you have the movieclip linked to a class in the properties. ?
[Code]....
my workaround is to send the attached movieclip into the constructor of the class, then use it from there, this will somehow make it work. But then I'm losing the point in directconnect the baseclip to the class in the properties.. example: attaching mctest.fla (cs4 file) and baseclip.as
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.
Just been playing around with the tutorials, on the Set properties/Get properties. Everything is all cool, except the "instance name" aspect. I dnt really understand that too well. Is it possible to change an Mc Name dynamically? If you look at my FLA when you hit the top left red button you will get a trace of the mcName as "square". Now if you input a new mc Name on the right hand side, you will see it change on the left hand side. But i want to know why it doesnt remain as the new mc Name, it still goes back to square.
View 3 RepliesI forgot to put it in the title so I'll just place it here; I am using AS 2.0. I know that there are other ways to accomplish the goal that am after, but I was wondering if anyone knows of a way to access the properties of an object's properties?
Here is the code that I thought of, even though it doesn't work
var a:Object = new Object();
a.bproperty = 0; //lowerlevel properties
a.cproperty = 1; // lowerlevel properties
[Code].....
This really just boils down to how I am organizing the code(I have ideas on what do next, and i am 99% sure that I can get them to work), and if there is a way to dynamically access the properties of the objects properties, It will save me from creating yet another large block of code for my project.

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.
