I'm just trying to avoid rolling my own dragging functionality - anyone know of any libraries out there that have a startDrag() equivalent where you can use, say, a circular radius for the drag bounds, rather than a rectangular box?

View 2 RepliesI have a movie clip that can only move to certain parts in the stage. For this I used another movie clip that supposedly should constitue the rectangle constraint. But this doesn't seem to work !startDrag(this,true,bounds._x,bounds._y,bounds._x+ bounds._width,bounds._y+bounds._height);
View 2 Repliesi have an .as class that extends mx.containers.Canvas (it's a draggable border of a resizable component), it becomes draggable on MOUSE_DOWN and stops being draggable on MOUSE_UP, MOUSE_OUT and ROLL_OUT. before calling startDrag() i create a Rectangle to define the drag area, i also have a _dragging: Boolean variable to control if it's draggable at the moment. the problem is that when i click this border it jumps to a negative coordinate without calling startDrag or switching _dragging to true.
i've overriden get x, set x, get y, set y and move() methods in order to solve it but the only thing i got was the fact that position changes without calling coords setters or move(), but at the moment it's changed a getter is called and returns new (negative) value so my question is what happens on startDrag() and how to filter unwanted incoming coords values?
as you can see, I have a container MC which I have added to the stage. I set its drag constraints using a Rectangle(). I then add the 'cat' child movieclip to the container, and I want this to be dragable too. However, as soon as I click on my cat when testing the MC. It shoots to point x=0 y=0 on the stage and doesn't move.
The container MC can be moved without any trouble.
If I remove the rectangle bounds from the containers startdrag() function. both MC's can be dragged without any issue.

is it possible to make button in a different shape for example i have a figure that i cut from image on a transparent background an i was wonder if it is possible to make that person in to a button but just that person not the transparent background.
View 1 Repliesis it possible to create a non-square "button" in flash cs4 programmatically using as3?
Using a xml document, i'm trying to be able to retrieve a png file with transparency, and have said transparent area's be not clickable.
Long story short, I'm creating a map with a bunch of clickable areas. These areas are non-rectangular and I need them to not obscure other area's which would be in their rectangle. I need this to be done programmatically since the area's are going to be dynamic as is the data attached to them.
fyi: I have a fairly good grasp of OOP, so don't be afraid to post up complex instructions.
I'm loading bitmaps dynamically using AS3 and I'd like to fit/tile them within a movieclip. (like a texture but in 2D)
However, my movieclip is not rectangular and everything I tried resulted in the texture getting out of the boundaries of my movieclip and being displayed as a big rectangle.
When you call startDrag on a Sprite/MovieClip/whatever, you can specify a rectangle which the object in question will stay within.
Eg... startDrag(false, rect1); where rect1 is of type :Rectangle
how you would go about constraining the dragging to an arbitrary shape, say a triangle or a circle rather than a rectangle?
I figure I could just have a Timer calling a function to check the whole time but that doesn't seem particularly nice.
I have a movie clip which contains a circular image, and by default Flash CS4 gives it a rectangular bounding box. This is a problem however because I am using this movie clip as a button, so the rollover area includes the entire rectangular bounding box and not just the circular image. How can I change the shape of this rectangular bounding box?
View 2 RepliesIn my app, a user must drag and release a rectangular mc object (rectx) over an irregular shape within another mc object (irregx). There are 13 rect/irreg pairs. Each obj shares an AS2 file that checks whether rectx is over irregx, and proceeds _only_ if the check is true. The script uses hitTest, on mouse release, to grab the number (x) of the rectx being dragged and checks whether it's over irregx. Right now, the check comes back true when rectx is _anywhere_ inside irregx's bounding box whether it's over the actual image or not.
I've noticed that, when the (unpressed) mouse rolls over any irregx, it's oblivious to irregx's rectangular bounding box. It only reacts when it reaches the edge of the irregular shape inside, toggling from arrow to hand at the image edges. Since the mouse knows where the irregx image boundary is, is there a simple way to tap the mouse's 'eyesight' to verify whether rectx is over the correct irregx shape (meaning not just within the bounding box, within the shape inside it)? This can't be that hard.
I've been following this tutorial to crop images in flex: [URL]
At the heart of its cropping is using a method called "copyPixels". However, this method takes as one of its arguments a rectangular shape for its crop region. Are there other strategies I can use to crop it not using a rectangle.
I am going after letting the user specify the region that should be cropped using a series of points.
If it's possible to zoom into a video? For example specify a rectangular region in the video and zoom in.
View 1 RepliesI have a vector movie-clip of a cat. Behind it, there is a picture of a park. The picture of the park takes up the entire stage, but the cat is only 32x16. How could I use BitmapData to sample all pixels (of everything, not just the park) within the cat's bounding box (but not including the cat itself in the samples (so like the cat is invisible); also 4 pixels wider in each direction, so it would effectively be 40x24) and then return the RGB average (in hexidecimal) so that I can set a masked transparent mc in front of the cat to that value?
Basically, so it looks like the color of the cat's surroundings affect its tint, to crudely simulate global illumination in 2d.
I am developing a game with Flixel as a base, and part of what I need is a way to check for collisions along a line (a line from point A to point B, specifically). Best way to explain this is I have a laser beam shooting from one ship to another object (or to a point in space if nothing is overlapping the line). I want the line to reach only until it hits an object. How can I determine mathematically / programatically where along a line the line is running into an object?
I could try measuring the length of the line and checking points for collision until one does, but that seems like way too much overhead to do every frame when I'm sure there is a mathematical way to determine it.
Edit: Before checking an object for collision with the line itself, I would first eliminate any objects not within the line's bounding box - defined by the x of the left-most point, the y of the top-most point, the x of the right-most point, and the y of the bottom-most point. This will limit line-collision checks to a few objects.
Edit again: My question seems to still not be fully clear, sorry. Some of the solutions would probably work, but I'm looking for a simple, preferably mathematical solution. And when I say "rectangle" I mean one whose sides are locked to the x and y axis, not a rotatable rectangle. So a line is not a rectangle of width 0 unless it's at 90 or -90 degrees (assuming 0 degrees points to the right of the screen).
I am trying to resize a rectangular MovieClip at run-time (dynamically). But, the problem is that it changes the width in both directions (left and right) from its transformation point. The same is the case with its height.
I want the width of the clip increase from left to right or decrease from right to left only.
How to create rectangular Box object through pure action script ?
I think, it can be done through the libary of movie clip but I am not sure. I want to take suggestion to create rectangular box through AS script
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.
