I am creating a game in which I draw a series of polygons by creating points around a radius of a cricle.
Later on I rotate the shapes and I need to calculate the new location (X,Y) of the points based on the rotation. I have the Old XY of each point, the XY of the center of the shape, radius of shape and the rotation.
Have a look at my diagram of the problem.
I try to calculate all the points on a curve.
The curve decided by the width(X on the picture) and height(Y on the picture) properties of a movieclip.The distance between each green point on curve is the same.
I'm needing this for a current project, so I have been digging around quite a bit (with little luck) on finding the distance between two points VERY fast. Yes, it is quite critical that it be as optimized as possible. I have the basics, Pythagorean Theorem run in different ways, as well as the Point.distance() function.
View 11 RepliesI am trying to make a program where I put in a bitmap map and then am able to calculate the distance between two points, and I have done that. Now I want to be able to zoom out and still have those two distance calculate the same distance apart, is there a way to do this with AS3 without have to manually scale my code?
For example I don't necessarily want to have to do
var distance = Math.sqrt(dx*dx+dy*dy)/scale...
Reason being is I would have to redo a lot of code.
I have this <s:list> with an itemrenderer and arraycollection as dataprovider. Now my problem is I want to be able to drag and drop to reorder those items. To do so I need to know the dragged item index, and the drop location. I have the selected item index but when I want to calculate my drop location using this code in my dragcompletehandler()...

I have found many posts on how to draw shapes using the drawing API. However, I'm trying to figure out if it is possible to get the coordinates of points along an exisiting path on the stage and then tween these points to new random coordinates (distort the path).
View 5 RepliesAlright, so I've been struggling with this one since last night. When I create a new object (a new unit), and draw it to the screen (Flash does all the work there), the point at which it's first placed is considered its origin. That is, getX and getY will return the distance from that point... Why is that? Or how can I stop this?

I as this working in AS2 and need to update to AS3...shows that AS3 doesn't like sloppy coding. Here's what I need: I pull data from an XML and that works when I put the data into a dynamic text box. However, I can't seem to get the date of birth into a variable. I have some code that calcs age in years but uses a string literal that I thought I could just replace with a variable from my XML...ain't a workin'. Here's the code I have:

I have been tasked with trying to create a drawing tool that draws dotted lines as you drag the mouse across the stage. I can easily capture the points on MouseEvent.MOUSE_MOVE and store them in a vector and then draw the points as dots:
The problem is that I need to calculate evenly distributed points on an ever growing Vector of points so I can only draw the line between say every 5th point (say using modulus). I have been battling away with Bezier curve equations both Quadratic and Cubic but still can't quite figure out how to convert my Vector of points into an evenly distributed Vector of Points without sucking the life from the CPU.
I am trying to make an object tween from its starting location to the location of a mouse click. I have a script, but it has a very annoying ease to it.I would LIKE the object to mantain a certain speed during while traveling from its starting location to the mouse click location.

However, it won't open in the browser in a different location. I pasted the html code in a web page but it doesn't work there nor opens in the browser in a differnet location from where it was originally published and saved. Why is that?

View 8 Repliesusing the shape tool you can draw basic shapesthen using the subselection tool you can re-shape them by relocating certain points
What i want to do is create a tween whereby one of the points is movedthe problem is you have to convert to a symbol first and after you have done that you cant change the shapes shape.so how do i go about using a motion tween to change the shape of a shape?
I am facing a curious issue. Generally when we draw lines in Flash either vertically or horizontally or through exact 45 degrees on either of the sides, they come out as straight and anti-aliased. While if they are drawn deviated from either 0 or 45 degrees, they come out as jagged. I want that to be anti-aliased too
View 1 RepliesWhen I select the text tool in Flash and click on screen to type, my text box is default rotated 90Ė clockwise. In addition, the text is default bottom aligned so when you hit return, the next line is above the first line. So, simply rotating it back doesn't
Even my properties box align buttons are rotated: I should add that the little rotation button you see for "orientation" is not the fix- it rotates individual letters.I can't find anything in the menus, toolbars or preferences to change this...
I am trying to create a mindmap where the user can drag points about the screen. I have gotten as far as drawing the line via actionscript, and drag+drop the points (defined as movie clips on stage). This is the existing script - I don't know how to get the lines to follow the points. Something to do with ENTER_FRAME or updateAfterEvent?
var line:MovieClip = new MovieClip();
line.graphics.lineStyle(1,1);
line.graphics.moveTo(ptOne.x,ptOne.y);

this math isn't working well. I'm using it for a rotated drag and drop (of a tone arm on a vinyl, a kind of abstract turntable simulation). Right now it just moves a bit in the middle of the vinyl (values between 21 and 36, is this degree or what unit is this?), but it should move between the two edges. The problem is that I don't know enough about trigonometry functions. Therefore I can't optimize the math for envisaged behaviour. Does anybody have an idea/tip how I can get a bit more control on the math and its effect? (maybe with more trace functions)

I have created a simple text scroll ( on (release) {object.scroll += 1} and it works fine.
Now the image in the background is slightly tilted so I have to rotate the text box a bit and I do this the text disappeares.
Any Idea how to get that rotated text box visible when rotated?

View 3 RepliesI have made an application where you can design your own greeting cards. I use matrices to scale and rotate images, and I always need to know what scale the image has.
It works when the image isn't rotated, by taking the value from matrix.a or .d which are the scaleX and scaleY values. But when I rotate the image, using the matrix.rotate() function, the a and d values no longer corresponds to the scale of the image.
How can I get/calculate the scale value of an object that is rotated? And I don't want to scale the image by using the scaleX and scaleY methods.
