Actionscript 3 :: Point Closest To Combined Geometric Shapes (compound Shape)?
Feb 20, 2012
I have a single point and a set of shapes. I need to know if the point is contained within the compound shape of those shapes. That is, where all of the shapes intersect.But that is the easy part.If the point is outside the compound shape I need to find the position within that compound shape that is closest to the point.These shapes can be of the type:squarecirclering (circle with another circle cut out of the center)inverse circle (basically just the circular hole and a never ending fill outside that hole, or to the end of the canvas is there must be a limit to its size)part of circle (as in a pie chart)part of ring (as above but lineThe example below has an inverted circle (the biggest circle with grey surrounding it), a ring (topleft) a square and a line.
If we don't consider the line, then the orange part is the shape to constrain to. If the line is taken into account then the saturated orange part of the line is the shape to constrain to.The black small dots represent the points that need to be constrained. The blue dots represent the desired result. (a 1, b 2 etc.)Point "f" has no corresponding constrained result, since it is already in the orange area.For the purpose of this example, only point "e" is constrained to the line, all others are constrained to the orange orange area.
Is there an easy way to add a stroke to a geometric shape other than a modified glow filter? Say you draw a series of points and fill it in so you have a star pattern, how would you go about adding a 1px or 2px stroke to it?
I've got a grid of sprites.Now I would like to drag an image on a grid-element.Therefore I need to know which x/y of the grid-element is the closest point to the mouse-position.
The idea is to fill some custom curved shape surface with generated circles with various radiuses. Look at attached image.
Well, I assume I know what approach I should use, but getBounds() will not work in my case, since the shape is not a square. So I think I need to get the 'targetCoordinateSpace' of a custom shape, but I don't know how to do that and I'm not even sure if that will work.
Is there any way to get the positions of points in a shape on stage at runtime? for instance a triangle, is there any way to get the positions of the 3 points that make the triangle?
to draw them. Each shape has a different color for fun (different beginFill).How can I get the color of the shape under the mouse pointer as I move the mouse around the shapes?I see two choices so far but don't know how to do either of them: Get color under the mouse point get the color from the shape properties (preferred)how to do either of these...
draw a shape on the stage, make it into a movieclip, registration point wherever, tl is fine, name it mc, and put his code:
trace(mc.getChildAt(0).y);
now get inside a movieclip and move that shape around (away from registration point) for example above registration point, or wherever and output will always be 0.
Given a MovieClip containing a vectorshape (loaded from the library) - is there a way to check whether a line (from point(x1,y2) to point(x2,y2) intersects this shape?
var shape1:Shape; shape1=draw(); addChild(shape1); shape1.rotation=50;
[Code]....
Then I want to rotate the shape at it's center point(200,202) by using shape1.rotation=50,but I find the shape don't rotate at the the center of it's shape. How to realize the function which make shape rotate at its center point?
I´d like to know if it´s possible to find a minimum y point (where the shape ends) of a shape, in a given x coordinate.
Example: I have a complex shape like a big "S". Suppose the "S" minimum x coordinate is 0. How can I find the minimum y point of the "S" (again, where the shape ends) in the x coordinate of 14?
Here is the image: I need to find the y coordinate (or point) of the blue point in the image.
I need to have 2 kinds of masks, one with a registration point in the top left so that when I tween its height it expands downwards, and one with a registration point in the bottom left so that when I tween its height it expands upwards?how do i do that, with code ofcourse?i have made something but i dont know if its the right way:(this expands downwards, but i dont know how to get it to expand upwards)
Code: import gs.TweenLite; var subMask:Shape = new Shape();
I want to make an editor like this site. [URL] If you browse this link you will find "Button. If you press this button you will navigate to a editor to design your layout. After draw a rectangle or circle or line you can resize that or can rotate that. When you finish if press the "you will back to the previous page where your desinged layout display. If you press the "" again then you will navigate the editor with the previously designed layout. I want to make a site like this. I want to use the flash cs4 to make the editor. Anybody knows how to draw a rectangle or circle shape with mouse and how to scale by setting the point and how to rotate by setting the rotation point also by using flash cs4 and as3?.
This should be a bit of simple geometry: How do I calculate the points to draw the lines in the code below so that it makes a 2D cone or wedge shape?
import flash.geom.Point;
//draw circle var mc=new Sprite()[code]...........
UPDATE:I should have mentioned my aim is not to draw a wedge shape, but to draw a line from a random point to the edge of an existing circle.If you're more comfortable with algebra than actionscript,
Alright, 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 have a question about shapes (i mean the flash.display.Shape class). Is it possible to import Shapes directly from the library as Shapes and not as Sprites/MovieClips? Shapes are supposed to be faster than MovieClips/Sprites, right? So why is it only possible to import MCs/Sprites from the library? I understand that generally shapes could be created solely by actionscript, but in my case the shape comprises of many points and is curved - so it's quite infeasible.
Is there maybe some sort of plugin to generate code that would draw the desired shape from a drawn shape in CS4? And a last one: Are there any benchmarks out there for performance comparison between sprites/mcs/shapes? How much performance do i loose by using a sprite instead of a shape?
how to use setStyle() for style attributes defined for a CSS class, but how can I change compound styles via actionscript? For example, my TabBar uses the following CSS style as part of the selected tab definition:
.myTabBar s|ButtonBarButton:upAndSelected { }
I want to have a color defined at runtime, using setStyle() seems to be a solution there. Just don't know how to delve that deep in the levels of the CSS structure.
I'm not sure what this is called, so have Googled but am struggling.Imagine a line of 5 movieclips, user clicks one, it moves +10 pixels in Y. Then, the next two closest movieclips move +10 in Y, then the next two closest to those 2 move, etc etc.
That's what I want to achieve, but I don't know why to start researching. I could get it working in a very ugly way with mess code, but I'd like to make it as clean as possible.
So if the value of myVar = 50;..and the array holds the values 25, 100, 150, etc.I want to write a function that will be able to find the array element that's closest to myVar, which would be the first element in the array (myArray[0]), since 25 would be the closest value to 50.
How would I go about finding the closest instance to a certain spot? I was thinking about using the distance formula and looping through all the instances on the stage, but I don't know how to find the shortest distance between all those measured.
I want to find a script that compares colors in a given region and gets the closest websafe color.I found the color sampler class that returns the average color. So now I just need to learn how to get the closest websafe color to the average color. how to compare color values and get the difference?
I'm trying to make it so that there are a bunch of instances (let's say 20) that move around about the stage. There are also 5 other instances (let's call them followers) that move and rotate towards the nearest of the 20 moving instances. I achieved this with this code in an ENTER_FRAME event:
PHP Code:[code]....
This code is placed in the class file for the follower objects. The problem is that I don't want more than one follower following the same movieclip. I was thinking that after the for loop I would remove c (the closest movieclip and the one it is following) from _root.eArray[0] and put it in _root.eArray[1] so that the other followers would not count it when searching for the closest.
If I have a couple of animations in a single folder, it doesn't look like there is a way to animate the folder as a whole, so is it possible to group all the animations somehow and animate that?
