I know some basic trig. but how do i find an angle from an anchor point and a moving point?
adjecent = _root.anchor._x-_root._xmouse;
opposite = _root.anchor._y-_root._ymouse;
hypotenuse = ((adjacent ^ 2)+(opposite ^ 2)) ^ 0.5;
I'm not a genius in geometry, I'd like to find a point in as3 with the radius and a angle but I don't remember the rule, I know this should be simple!
View 3 RepliesI am looking for a way to find a vector if I know one point and 1 angle. Like I have A(x, y) and a vector starting from A(x, y) with an angle. I would like to know the position on a point X (x, y) that can be anywhere on that vector. I only know the coordinates of A and the angle. Possible?? I guess it has to be a function...
View 5 Repliesi'm a novice to ActionScript but from failed Google function searches, i think i've choosen an advanced i hope possible task: how to read then apply bezier, anchor point and handle positions to different anchor points. What i need to do is precisely align a rectangular closed bezier path with a randomly shaped closed bezier path, both with the same number of anchor points.
View 9 Repliesif i have a movieclip or a sprite could i find (via code) where is its registration point compared to its top left point (no rotation included) ?
View 4 Repliesi 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 )
Is there a better way to have a symbol's anchor point default to the size of the stage? I'm having Huge problems because if two symbols are different sizes then I can't tell two objects to be in the same location.The workaround seems terrible. I have a guide layer for stage bounds. I'd have to duplicate that, add that to the objects that I'm going to want to convert to a symbol first, then remove it after it's converted. Is there anyway to automate any of that? That just seems like a terrible task to repeat over and over. I suppose one option is to have a blank symbol that is the correct size already, duplicate that in the library, rename it, put that on the stage, then put your objects in there. Wow, I'm not sure if that's better or worse!
View 1 RepliesFlash knows where the anchor point is in 3D space in order for the symbol to rotate around it, but I can't seem to figure out how to see the coordinates of the anchor point or type in new ones. Please tell me how to do this. I am already very annoyed that Lynda, a pay service, doesn't think this is vital information. Apparently they think we would never want to do anything more visually stimulating than one simple spinning logo! But I digress...
Just to be clear, I know how to move the anchor point visually on the stage, but I want accuracy. I want to be able to give two symbols the exact same coordinates to rotate around.
I have a dynamic image loading into a movie clip and i dynamically created a transform box around it. However the anchor point of that transform box is coming on the left top instead of in the center, which is not letting the image transform properly. how to dynamically put the anchor point to center through AS2?
View 1 RepliesThe following is a link to an online floor planner:[URL]..Does anyone know how to achieve the anchor point function? If you click on a "wall" it adds an anchor point.
View 0 RepliesI've been playing around with Flash's native 3D in pure AS3 (in FlashDevelop, not the Flash IDE) and am having a heck of a time finding documentation on how to set the 3D "anchor point". (Perhaps it goes by a different name?)
Can anyone tell me the API, Class, or command(s) needed to move the anchor for a given Sprite or Stage?
I'm trying to Resize a panel using a Resize Effect using its center as the anchor point. I've been googling for some information and the only thing I have found is to set the horizontalCenter and verticalCenter to 0, but this is not working for me. The panel keeps resizing from top/left corner.
View 1 RepliesI am generating sprites programatically like this:
this.food = new Sprite();
this.food.graphics.beginFill(0xFFFFFF);
this.food.graphics.drawRect(0, 0, 10, 10);
this.food.filters = [new GlowFilter(0xFF6699, .80, 5, 5, 2, 2, false, false)];
this.food.graphics.endFill();
[Code]...
I basically want the food sprite to spin slowly about its center, not its x and y value which is the top left corner of the sprite. How can I make the anchor the center of the sprite?
Is there any way to change the anchor point of an empty MovieClip that was created dynamically.
View 2 RepliesHere we have some great flash websites: [URL]
See how the URL is changing depending on how you are going inside the website sections? This is actually great because you can use the <BACK button of the browser in a flash app.
How can this, URL thing, be done? I hope the technique does not involve creating 8 different SWFs for the 8 sections of a site because that will not be actually a trick... It's defenitely something else looking at that "#" thing.
The website I am designing is a single-page site which scrolls using jquery to anchor points on the page (instead of having separate html pages for each section) The intro section has a flash banner which alternates images of different sections of the site. I have used the following code to get these images to link to the relevant page section
name_btn.onRelease = function() {
getURL("#anchorname");
};
This however just jumps to the named anchor point - I need to make this scroll to the anchor instead to keep it consistent with the rest of the site.

I'm importing an external image, but by default the anchor point (coordinates 0,0) for the movieclip it loads into is the top left,this is obviously an issue if I want to rotate, as I need coordinates (0,0) to be the centre of the image, not the top left?
View 2 RepliesHow can we find out a moving movie clip's angle. I'm trying to make a shooting game in as3, I need to know the angle of the movieclip(bullet) when it gets hits on the wall. i.e., I have a movieclip named "ball", and which is moving with some speed and the coordinates are initially created by the gun's positions.
Code:
var angle:Number = gun.rotation - 1;
var bubbleX:Number = gun.x-130* Math.cos(angle * Math.PI / 180);
var bubbleY:Number = gun.y-130 * Math.sin(angle * Math.PI / 180);
var ball:MovingBall = new MovingBall();
ball.x = bubbleX;
I need to know, what is the angle of "ball" after it hitting the boundary areas..
I have a set of links (movie clips) arranged in a circle. When one of the links is clicked, I would like the circle of links to rotate until the selected link is in a certain position - straight down (90 degrees) in this case - and the others to maintain their positions relative to the clicked link (ie: they all move, but the distance between them is maintained). The behavior is intended to be like a bullet rotating into a chamber on a revolver, or - more accurately - like that of a Ferris Wheel.

ActionScript Code:
// setting variables
var centerX = Stage.width/2; // Stage Center X
var centerY = Stage.height/2; // Stage Center Y

I have a slider which I want to use to rotate an image around it's center. This normally is easy but my problem is the clip is made dynamically and the size changes so I can't use the default registration point and I need to assign the center point before I rotate it. I found the rotateAroundExternalPoint function which rotates around a center point fine. How to get it to rotate to a certain angle and then have it stop at that angle. The rotateAroundExternalPoint increments the rotation rather then allowing me to set the angle to rotate to. Is there anyway that I can set what angle to rotate my clip to? It right now increments the rotation by the x coordinate of my slider bar (slider_position.x).
Code:
import flash.geom.Matrix;
import fl.motion.*;
var mat:Matrix = clip.transform.matrix;
addEventListener(Event.ENTER_FRAME,EnterFrame3);
function EnterFrame3(event:Event) {
var center_point_x = clip.height / 2
var center_point_y = clip.width / 2 //
MatrixTransformer.rotateAroundExternalPoint(mat,center_point_x,center_point_y,slider_position.x);
clip.transform.matrix = mat;
}
how I can count the B point's coordinates (see attached image... or not as I am a new user...pf!). I know the arrow's rotation - so the angle (let's say it is -120), A's coordinates (0, 0) - A is the middle point of the arrow, and that the distance between A and B is 50 px.
View 1 RepliesSo let's begin. I want to build a wheel which you can spin, similar to a roulette wheel. You can do this both ways (CW and CCW, this issue causing the bug, actually). The wheel has some acceleration to it too, and I achieve this by measuring the start and final angle of the drag movement, using Math.atan2(dy, dx). The problem is the following: atan2 outputs the following angle scheme, assuming the point relative to which the math is done is in the center of the circle.
atan2 returns a value measured in radians, so I'm using the classic angle*180/Math.PI formula. I've changed this original scheme into the following, using some simple math to shift the angles a bit, to resemble more accurate circle angles (going up to 360 degrees) The problem that I'm facing at the moment is should the user decide he wants to swipe clockwise, and moves through the right point, where 0 turns into 360 or 180 turns into -180, the whole angle difference thing is capsized. It registers a CCW movement (as if the user swiped his mouse all around the circle). So, I'm looking for some ideas as to how I can work around this small issue.
i am trying to find center point of my pie.
var myTween:Tween = new Tween(piechart,"............", Strong.easeOut,1200, 510, 1, true);
i want to animate from the center and it has a xml driven data file.
Im pushing Point locations into an array to Shift em out later. like this:
tempmoves.push([new Point(roundx,roundy)]);
..
ob.movestoplayer = tempmoves;[code]....
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 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.
