ActionScript 2.0 :: Find MC Center Relative To Edges?
Aug 31, 2010
I don't seem to be able to find the right wording to find my answer anywhere.How do I determine where an MC's center is relative to its edges?I'm developing a tool that a variety of noobs (as if I'm not still a noob) will be using, and I don't trust them to keep art with 0,0 being the top left corner.How do I figure out that the left edge is now at -111px, and the top at -52, and the right at 12, and the bottom at 334?
I am in the midst of finishing up a design application where you can upload images and colors. I use the greensock transform manager. I am taking anything a user does and recording it so I can recreate what they made on larger scale behind the scenes (to be exported for printing purposes)
The problem I am running into is with rotation and moving x and y values. The transform manager does everything relative to a center point, but when i recreate the image object the registration point is at the top left. I have found how to rotate around the center of the object using the transform matrix, but I can't seem to move the x and y correctly because these values change when you rotate. I want to just move the image to the left or right relative to the center. How could I go about doing this.
Here is how I rotate.
private function rotateAroundCenter (ob:*, angleDegrees:Number, ptRotationPoint:Point) { var m:Matrix=ob.transform.matrix; m.tx -= ptRotationPoint.x;
I've recently taken Krilnon's tutorial on interactive image panning, and have a need for more complexity. My image to be panned (relative to user's mouse movement) has several 'hot spot' buttons placed within. Each hot spot, when clicked, is to smoothly zoom and shift within the mask, with pertinent info displayed next to each, once zoom and shift is complete. almost like I'm making a motion tween, where the final position is known, but the start position is wherever the BG image is when the user clicks the nested button. I need to determine the x-position at the moment of click of the button (different for each button), and then, I think, use a simple-math "stagger-step" method of moving and scaling, until I've reached my final dest. here's the link to the tutorial I originally referenced:If anyone knows of a tutorial or example out there, I'd love directions to it(them). or,
All though I can scale down the size of my objects and can shift them to their correct positions when scaling. I cannot shift them to the correct relative positions, relative to the screen centre.
Code: level=1; //starting scale level public function scaleOut(level:int) // scale to a level 1-4{ for (var r = 0; r < Main.ballArray.length; ++r){ // scale radius Main.ballArray[r].bRadius *= (oldLevel / level); [Code] .....
I have been trying to figure out a good strategy to perform a bitmap crop using Actionscript3. For example: I have a picture of a car and I want to crop out the car from the image alone and feather the edges so that they do not look jagged.
I am a flash noob and have only been using it for a couple of weeks. I've tried a couple of options and here is the last one that I have come up with it: I place red dots on stage that are draggable so that you can outline the object you want to crop and the dots are the bounds for a gradientFill that is used as the bitmap's mask. (I am using a radial gradient ... so the results are far from what I want, since the car is not an oval).
[Code]...
1) How can I fade just the edges of this custom-shaped fill outlined by the red dots?
2) I want to save the image out to a file once it's cropped. What strategy would be better for doing this using a BitmapFill or a GradientFill as a Mask (If it's possible with both)?
3) I may be using this strategy to crop faces later on.. anyone know of any good face detection APIs for as3? (also edge detection APIs)
Recently a client of mine decides he wanted rounded edges for his page vs. the typical square edges. This was after the initial design and at the point where it is almost complete.I told the client that in order to do this we would have to go to a full Flash web page meaning a full browser Flash page (everything is already flash).Now I told him that we could do this but because it was a new design and as you know that there is much involved in doing something like this i.e. all the paths will have to be changed because it will have to reside inside a mc etc.if there is an actual way to make the stage rounded only for future knowledge.I know I can make a round edge square or rectangle but it still has square edges at outer edge of the stage.
So let's begin. I want to build a wheel which you can spin, similar to a roulette wheel. You can do this both ways (CW and CCW, this issue causing the bug, actually). The wheel has some acceleration to it too, and I achieve this by measuring the start and final angle of the drag movement, using Math.atan2(dy, dx). The problem is the following: atan2 outputs the following angle scheme, assuming the point relative to which the math is done is in the center of the circle.
atan2 returns a value measured in radians, so I'm using the classic angle*180/Math.PI formula. I've changed this original scheme into the following, using some simple math to shift the angles a bit, to resemble more accurate circle angles (going up to 360 degrees) The problem that I'm facing at the moment is should the user decide he wants to swipe clockwise, and moves through the right point, where 0 turns into 360 or 180 turns into -180, the whole angle difference thing is capsized. It registers a CCW movement (as if the user swiped his mouse all around the circle). So, I'm looking for some ideas as to how I can work around this small issue.
I'm trying to figure out how to find a point relative to the center of an object, modified by its rotation. For example, in the attached swf, I've been messing around trying to draw trails to a bitmap, coming out of the thrusters. I didn't have a problem at first, but as the ship rotated, the lines that were being drawn wouldn't remain relative.
http:[url]....
I'm sure this is because I have no idea what I'm doing, and I've just been sort of idioting my way through it. That aside, is there an easy way to find the point I'm looking for? For instance, say I want a point at Y -14 of my ship, but I want that to remain relative to the ship as it rotates.
I created a movie where I have a circle in the middle and a line drawing from the center out when the mouse moves. I want to calculate the distance from the mouse position to the middle of the circle. What I am going to do is have a sound playing from the center of the ball..The closer you get the louder the sound gets and the further away from the middle the quieter it gets. You can download my fla to see what I have so far.
I have a AS2 movie clip that has a drag navigation. The movie clip is bigger then the visible area. How can I find the center xy of the current visible area when I stop the drag?
I'm trying to add some zooming functionality. The problem is that when you zoom in and out, it scales the MC up and down from where the registration point is. This means That when I'm far from the position of the registration point instead of zooming the in straight it also makes it appear as if you are travelling towards the registration point.
To offset this effect I want to calculate the amount of pixels I need to offset the Map by so that it appears as if you are zooming in directly.
So just as a test I've put a little ball inside the map(called "center") which I'm trying to keep in the center of the map.[code]...
I am new to Flash and ActionScript 3.0 environment. I don't have any knowledge in depth with Flash and ActionScript 3.0. I am using the flash(.swf file) in my Java application. Now, this .swf file is to be placed in the server system. While I am working with these, I faced an error. Here, my issue/problem(s) starts....
1.)With the help of URLRequest & URLLoader classes, I am loading a jpg file dynamically onto the stage using the following code:
I have a center window and a background in my flash file. I am trying to get the center window to stay in the center of the web browser screen and get the background to expand and fill the entire web browser screen below center window layer. Sort of like this site [URL] I've currently converted the background to a movie clip and have this code.
My flash movie is 1440x900 but the area where all the important stuff happens in within 1024x768, i am trying to keep the middle in the center regardless of browers size or aspect ratio.
I can center the page but it doesn't work as i need it to. If the browers is small (1024x768) the swf is justified against the left edge, but not keeping the middle in the middle of the brower.
[URL] is an example of exactly what i am trying to achieve.
I didnt see a place in preferences to keep edges hidden. I have some text that has a dotted line around it. I can hide it with hide edges, but as soon as I select them and let go, the edges come back. maybe their not edges since theyre dotted. maybe its flash telling me somethings not set up correctly? anyone?
I want to make a rotating cube with rounded edges.I already saw lots of cube sources, but i need one with rounded edges.My maths actionscript is not so good.
My file is going great but I would like it to only pan right or left when the mouse reaches close to the edge and stop while I am working within the middle area. Here is my panning code and the file can be viewed at [URL].
The transitions between sections is a bit harsh, I'd like to smooth it out some by fading from 1 color to the next or something.The captions don't sync up with the pictures the first time around until the pics are cached.When you click on the button of the section you are in, the slideshow stops.
I want to make a rotating cube with rounded edges. I already saw lots of cube sources, but i need one with rounded edges. My maths actionscript is not so good.
I've found using the 3D rotation tool to give rough/jaggy/pixelated edges to my vector clips, even after using:cache as bitmap"stage.quality = StageQuality.BEST;" in Document classIs there a way around this?
I have seen people complain about this, but no work arounds. The blurry eddges I see on the rounded portion of round rectangles is awful. IS there a workaround?
Flash has some serious problems with jagged edges on curved shapes. When adjusting a curve on a shape, flash shows that it is curved and then on releasing the mouse it turns into a sharp edge
I'm creating a shape in code based on some random points and then using it as a mask for an image. What I'm hoping to do is have the mask fade the image to transparent around the edges. I know I can do this using a gradient mask, the issue is how do I create a gradient on a shape that just fades out around the edges? The shape is not regular, so a radial or linear fill just won't cut it.
I want the map's movement to be constrained to the edges of the stage. Or in other words, if you move your mouse from the left edge of the stage to the right, you only just see the right edge map, whereas now, it dissappears off the other side of the stage.
I have recently started Learning Actionscript 3.0 out of my own interest. I was trying on making a ball bounce off the edges of the stage using the Actionscript 3.0. But the code not working. The Ball happens to move on X and Y, till it hits the end of the stage, and then it just does not reverse its direction to give the effect of bounce, it gets stuck to the X axis and moves out of the stage. I tried to make changes, but failed.
Code: function bounceBall(evt:Event):void { var vx:Number=Math.random()*10+5; var vy:Number=Math.random()*10+5; var radius:Number=mcBall.height/2; var top:Number=0; [Code] .....
