Flex :: Calculating The Area Of A Polygon When The Polygon's Points Are Lat Longs: Which Function Is More Accurate?
Jul 28, 2010I'm trying to find a way to calculate the area of a polygon using lat long coordinates in a Flex 3 site. Hong007 on Google Maps for Flash group was cool enough to post the following function:

I was also playing around with the area calculator at [URL]. These functions produce slightly different results. I'm trying to figure out which one is more accurate. It seems that hong007's function produces results that are on average slightly larger than freemaptools' function. However, I don't know which one is more accurate.
Flex :: Determine If A Series Of Points (or Polygon) Is Within A Rectangular Region?
May 20, 2011I have been looking at posts about determining if a point lies within a polygon or not and the answers are either too vague, abstract, or complex for me. So I am going to try to ask my question specific to what I need to do.I have a set of points that describe a non-straight line (sometimes a closed polygon). I have a rectangular "view" region. I need to determine as efficiently as possible whether any of the line segments (or polygon borders) pass through the view region.
I can't simply test each point to see if it lies within the view region. It is possible for a segment to pass through the region without any point actually inside the region (ie the line is drawn across the region).Here is an example of what I want to determine (red means the function should return true for the set of points, blue means it should return false, example uses straight lines and rectangles because I am not an artist).
Another condition I want to be able to account for (though the method/function may be a separate one), is to determine not just whether a polygon's border passes through the rectangular region, but whether the region is entirely encompassed by the polygon. The nuance here is that in the situation first described above, if I am only concerned with drawing borders, the method should return false. But in the situation described here, if I need to fill the polygon region then I need the function to return true. I currently do not need to worry about testing "donut" shaped polygons
Here is an example illustrating the nuance (the red rectangle does not have a single vertex or border segment passing through the on-screen region, but it should still be considered on-screen):For the "does any line segment or polygon border pass through or lie on screen?" problem I know I can come up with a solution (albeit perhaps not an efficient one). Even though it is more verbose, the conditions are clear to me. But the second "is polygon region on screen?"PS I have a function for determining line intersection, but it seems like overkill to use it to compare each segment to each side of the on-screen region because the on-screen region is ALWAYS a plain [0, 0, width, height] rectangle.

Professional :: Bug When Deleting Anchor Points
Oct 10, 2011I think I discovered a bug. Say this is a line with anchor points:
x---x---x---x---x---x---x
And this is what I want to achieve using the Delete Anchor Point Tool:
x-----------x-----------x
Then this is as far as I'm actually able to get:
x-------x---x-----------x
Because for some reason, if I delete the 2nd anchor point, the 3rd will be deleted too. I can, however, delete the 3rd without deleting the 2nd.
It is only after I've moved the 3rd further away that I'm able to delete the 2nd, but this gets tiring after a while.
Actionscript 3 :: Calculating Evenly Distributed Points On A Line Of Points
Oct 3, 2011I 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.
ActionScript 3.0 :: Polygon Drawing App?
Aug 10, 2011I want to create an app for drawing polygons with a variable number of vertices, with the following requirements (very similar to a vector drawing program such as Adobe Illustrator):
-each click of the mouse on the stage sets a vertice (e.g. draws a small square or circle to mark the spot), which draws a line to (e.g. LineTo) the prior vertice, and so on, until the final click, if close enough to the first vertice, will complete and close the polygon
-each of the vertices of the completed polygon should be draggable with the mouse, so that that completed (or partially completed) polygon maintains its integrity while changing shape, that is, so the user can modify the polygon shape without having to redraw it. it's the second step I'm having the most difficulty with...in general terms, how would I implement this? Perhaps each vertice should be a draggable Sprite containing a small square or circle graphic?

I open the motion editor and try to convert those keys on x and y channels to Smooth points. Motion editor shows now nice curves on x & y but nothing changes on stage. The motion of my movie clip is not changed in anyway. Its like those keys are still Corner points. No smooth motion. Of course I can change the motion path straight from the stage or create a custom ease to smooth motion.

View 1 RepliesProfessional :: Find Out Where The Link For A Button Points To?
Aug 10, 2010I installed a Flash template that has a "Read More" button which is used in several locations of the site. The button corresponds to a single symbol called "button_more" and another symbol within that symbol called "area_more". It's a "Movie Clip" type of symbol, not a "Button" type symbol.
What I'm trying to figure out is where would I find the link to the page where that button points to - it points to different pages of the site depending on where it's located. For example, in the About Us section it links to a page that has more details describing About Us. In the Services section it links to a page that has more details describing Services. So the same symbol is going to different links.
I checked the Properties of the symbol and it doesn't have any option for a link. (I guess it's not really going to a link, but to a different frame in the timeline) But where would I find exactly where each button points to in case I want to edit one of them in the future, or create a new button with a new link?

Actionscript 3 :: Breaking A Concave Polygon Into Convex Ones
Mar 16, 2010I'm using a game physics library (Box2D) which only supports convex polygon shapes. However, I'd like the level builder to be able to just specify concave polygons without having to worry about that. So, how can I automatically break apart a concave polygon into convex ones (or even all triangles). Speed would be cool, but ease of implementation is more important. The breaking apart will only be done on game initialization.

Obviously they're just hotspots, so I want them to be invisible, but searching for my problem only shows results for drawing polygons from coordinates using the graphics property of a movieclip.The data doesn't ever change, so it would be possible to just draw all the polygons manually with the pen tool, but the data is being used elsewhere, so it would be much easier to maintain if I could add new zones just by updating the text file.
ActionScript 3.0 :: Line - Polygon Intersetion Detection?
Aug 25, 2011I'm working on a method to do more accurate path finding for a special project. I haven't yet found any sources on this so i have to write it myself.
The idea was to use a polygon mesh, draw waypoints between all points then discard ways intersecting with a polygon. After that use dijkstra's algorithm to find the closest path.
Detecting whether a line intersects with a polygon mesh is the tricky part. I haven't yet come up with any viable solution that is fast. how i can determine whether a waypoint travels through a polygon?
Professional :: CS5 Bug: Symbol Rotation Points Shifting With Long Timelines
May 16, 2010I have come across a large, and very annoying bug in CS5. When animating with the same symbols over a long and complicated timeline, the rotation points of symbols earlier in the timeline begin to shift around very slightly. The more you work on the flash, the more they shift, so things that you did right at the start will begin to wobble around all over the place once your timeline gets very big. This is because, as we all know, when you tamper with a tweened symbol's rotation point, the symbol moves out of place while tweening.
This has completely ruined a large project I was working on that I began in CS4.
I am using a Mac Pro running 10.6.3
