Actionscript 3 :: Creating A Polygon From A Set Of Coordinate Pairs?
Dec 12, 2011
I'm making an app in Flash, and I want to define some polygons which I can bind hover events to to add annotations to an image.I can create these normally in Flash, but I want to load some external data, a list of coordinates, and create the polygons with ActionScript.
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.
I want to create a matching pairs card game within flash. I have found actionscript for a matching pairs game but it does not work the way i want it to. I would like to be able to match a Picture with a word as opposed to 2 pictures the same.
I'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:
[Code]...
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.
I have 3 square. smallest square s3 is inside s2. s2 is in side s1. each is 10px larger [code]how can I find the coordinate of child in its parent's coordinate system?
I want to load key/values configuration pairs stored in XML file. To bind a collection of data i know i need to use the ArrayList class, but the problem is that i want to be able to bind the loaded values using their corresponding keys and not by their indexes in the ArrayList object. For example i want to be able to do this :
[Code]...
So the question is how to bind the key/value pairs loaded form XML. I don't want to go manually set variables, i want to bind them so when they are loaded the are set automatically. Did anyone had to do something like that ?
I am attempting to make a flash object that receives name/value pairs to a swf that resides inside a LCMS. There is some documentation on the topic from the lcms, but very little support. The documentation says to instantiate the flash class called URLvars (which doesn't exist, so I'm using URLVariables) and says to use this code with the following example if the name/value pair is baseColour = 0x1c617D (essentially, then, the value of the variable baseC would be 0x1c617D):
var thisURL:String = _url; var vars:URLvars = new URLvars(thisURL); var baseC:Number = vars.data_obj.baseColour;
I tried to do this in a very simple object, but it will not pull the name/value pairs from the LCMS
is: I have array={0,1,2,3,4,5,6,7,8,9} and i want from this array unique random pairs.for example: 3,6 nad automaticly 6,3 no repeats.It must give me 10 pairs.for example:
I am making an user application where users can chat one on one for an x amount of time till they go to the next user (see it as speeddating). Only they are all women talking about women stuff like knitting or something. A friends chat.
I am stuck with making unique pairs. only the first round is going great (unique pairs), but then it gets mixed up:
[Code].....
As you can see everyone in round 1 is paired good. But in round 2 you see (for example) Donna talking to Cindy, but Brenda is also talking to Donna. that's not right. she can't talk to 2 people at once.
I 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'm trying to figure out how to draw a polygon from an array. I've found a few examples, one which the author says works, but am not getting anything to appear. I've traced the array (it's registering) and am getting no errors.
Code: //called from constructor polygon(thisArray);
I know that I can collect the pixels of a rectangular area within a Bitmap using getPixels(), but is there a way to collect the pixels of a polygonal area with more than 4 points? Or at least determine whether a particular pixel lies within a polygonal area of a Bitmap?
I am trying to put together a match activity where word in one column are linked by a line to definitions in another column. Once all words have been linked to their definitions, you end up with a series of crossing lines so, so I want the definitions and their line to move so that each is level with their connected word and the lines have unravelled. I've got as far as connecting the words to their definitions using a line (as a sprite) and the definitions can then be moved using tweenlite -but I have no idea how I move the lines with their definition. Here is a much simplified section of code to give you an idea of what I am trying to do
I'm building a map editor for a project and need to draw a hexagon and fill it with a solid color. I have the shape correct but for the life of me can't figure out how to fill it. I suspect it may be due to whether the thing is a Shape, Sprite or UIComponent. Here is what I have for the polygon itself:
import com.Polygon; import mx.core.UIComponent; public class greenFillOne extends UIComponent {
I'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.
I am creating a project in Flash using the Google Maps API and docs. I'm trying to add a marker to the map, which is draggable but I don't want it to look like the standard Google Maps bubble-style marker. Is it possible to have a custom polygon or image but still keep the draggability?
I'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?
I am creating a game where I have some red balls on the screen and some blue balls on the screen and I would like to draw a polygon around all balls of the same color and have this polygon automatically fill as soon as the polygon shape is closed. How to achieve this as I haven't really done much with the drawing API before. My current code will allow me to draw a polygon and for it to fill when I release the mouse but what I would like it to do is automatically fill as soon as the shape is closed.
Here is my code so far Code: var graphix = new MovieClip(); addChild(graphix); var points:Array = []; stage.addEventListener(MouseEvent.MOUSE_DOWN, startDrawing); [Code] .....
myNews=<FONT COLOR="#FFFFFF"><B>This is bold 24 point text</B><P></P><P></P>blah blah</FONT>
As i could read on macromedia 's web site:Use an empty pair of <P></P> tags to insert a line break. Use two pairs to insert a line break and carriage return.But this isn't working.
When I double click to close the selection, the marquee vanishes instead of closing the selection. Yes, I double click on the starting point.Here's what the manual proclaims (step 4): Draw a straight-edged selection area1 Select the Lasso tools Polygon Mode modifier in the options area of the Tools panel.2 Click to set the starting point.3 Position the pointer where you want the first line to end, and click. Continue setting end points for additional line segments.4 To close the selection area, double-click.
I'm trying to create a function that draws a polygon with two parameters that are: number of sides and length of sides. You would input a number for side length and a number for the number of sides. Then it would draw the side length, then turn at a angle based on the number of sides, then draw side length again... until it has finished drawing the polygon based on the number of sides that were put in.
I 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.
I'm working on a pathfinding algorithim using A* and using irregular polygon shapes as obstacles rather than a grid. I don't fancy plugging in all the points and links by hand and was wondering if there was some way I could just get them from a Sprite or MovieClip?
