ActionScript 3.0 :: Calculating Position Of Rectangle Corners
Jan 14, 2010
i'm in the middle of attempting to write my own collision detection algorithm because the built in 'hitTestObject' function seems to be incredibly inaccurate (it's registering 'hits' when the objects are still a considerable distance from each other).I need to be able to calculate the position of each of the 4 corners of a rectangle, based on its rotation. Obviously one of the corners will simply be the rectangle's x and y coordinates. I have made a little test program to make sure I am calculating the positions of the corners accurately - it works when the rectangle is rotated to 0, 90, 180 and 270 degrees, but produces strange results for any other angles.[code]

I'm trying to get plain straight corners on a rectangel. I have been drawing a rectangle or even before drawing one, selecting the little tool in the lower left and I put in a value of 0, but as soon as I draw anything it rounds up again. How do I get rid of this problem??

My idea was to create a method for drawing rectangle with rounded corners, but while being able to specify which of the four corners (any, all, none,etc.) you wanted to round. The method below does the trick, but for some reason my corners don't match the same curves that I get using the same radius with drawRoundRect(). In other words, if I call my method (and set all four corners to be rounded) and compare that with the same call to drawRoundRect() the actual curves of the corners are slightly different.
HTML Code:
public function drawComplexRoundedRect(startX:int,startY:int,rectWidth:int,rectHeight:int,radius:int,canvas:Sprite,roundTopLeft:Boolean=false,roundTopRight:Boolean=false,roundBottomLeft:Boolean=false,roundBottomRight:Boolean=false):void{
if(roundTopLeft){
canvas.graphics.moveTo(startX,(startY+radius));
[Code] .....
Then compare
HTML Code:
var canvas:Sprite = new Sprite;
drawComplexRoundedRect(0,0,200,200,25,canvas,true,true,true,true);
with
HTML Code:
var canvas:Sprite = new Sprite;
canvas.drawRoundRect(0,0,200,200,25);
and you will see the two rectangles are not identical.

e.g if the bounds of the loaded clip is
Rectangle(x=0, y=0, w=800, h=50);
What is the remaining Rectangle() to use of

The corners of a rectangle drawn with drawRoundRect are not very consistent when the curve/ellipse values are very low (2-5px or so), most visibly when there's a border added.Even with hinting turned on, there's still a pretty ugly difference. When set to 3px (horizontal and vertical), the right-side corners look pretty close at around 3px, but the left-side corners are very off, and both look to be maybe 1px curved.

I have a couple of images, representing tents, that look like this: The red and blue parts on each side of the tents are doorways, and several tents can be connected together via these doorways. For example, I want to connect the two blue doorways so that they match up like in this picture: If the first tent is stationary, around which point do I rotate the second tent and how do I calculate where to place it?
Currently, I have the upper left corner of each doorway as an x and a y value, together with the width and direction (in degrees) of the door. I'm treating the doorways as one dimensional, so they don't have heights. Would another representation suit this better? Perhaps a start point and an end point plus direction?

I am developing a game for mobile in AIR (as3). I have created some bots for this game that initially just wander around. But when a bonus enters the stage, they have to move to the bonus.The detection of a new bonus and moving of the bots works fine, but there is something wrong with the manipulation when a new bonus enters the stage.Basically, this is how it works (or I try to make it work):My bot moves along with his rotation as a parameter. (works fine)
private function moveToNextLocation():void
{
var angle:Number = _rotation * 0.0174532925; // 1 degree = 0.0174532925 radians
var speedX:Number = Math.sin(angle) * _speed;

I am drawing a rectangle with the above code in as3 inside a area. Problem is that, when i try to acees the drawn rectangle x and y position it is showing 0,0. if i drag the drawn rectangle and try to access the x and y position then also it is calculating from the 0,0 position. first time when i draw the rectangle it is drawing well by dragging the mouse but why the x and y axis is 0,0; if i try to set the x and y position manually then when i try to draw by dragging , it is not drawing relative with the mouse.

For those of you still with me, I am tasked with making some scrollable content in Flash. Load in a TextFile using LoadURL(), then display it. To get the text, we've written our own class TextFieldExtended, which is basically just there to give the textfile location to the constructor and then have the class do the various steps of getting it and loading it for you.So I needed to get a Scrollbar, which I got hereThe thing is, it works with Sprites.After trying to get it to accept TextFieldExtended, I bumped into a block, since the scrollbar relied heavily on a Sprite property that TextFieldExtended didn't have or could have.
So I tried adding the TextFieldExtended instance to a Sprite instance using addchild.A problem occurs here that I do not know how to handle. It seems that a Rectangle is drawn and the Text is drawn on that. I say this because the scrollbar moves the Rectangle up and down a bit, but the text doesn't scroll, just the Rectangle it is positioned in and the text then moves along with it.My question: can this be fixed, or is does this implementation of scrollbars need a lot of adaptations before this is possible?

I am trying to convert a rectangle(actually multiple rectangles) to a curved rectangle. I think it should be pretty easy but I guess i am stupid. Basically I would have a start position and stop position (many of these), and they would be converted to curved rectangles and follow in a cicrle around.

I would like to create a rectangle inside of a rectangle, starting approximately 15% inward from the right side of the other rectangle.
I know how to create rectangles with:
Code:
var newHotRect:MovieClip = new MovieClip();
newHotRect.graphics.beginFill(0x00FF00);
newHotRect.graphics.drawRect(0, 0, 100, 100);
addChild(newHotRect);
But how would I make another rectangle on top of that (the black one pictured) that is approximately 15% from the right?
I toyed around with .right, and .bottomright with no success. Can anyone lead me in the right direction? or even finding the x and y of the upper right or bottom right side of a rectangle?

corner-radius: 10;
} </mx:Style>

When I use <s:Rect> to create a rectangle, I use radiusX to get rounded corners. Problem is all are the same roundedness. Is there something similar to Rect that lets me control the radius for each corner separately? If not, what's the best way to create this from scratch? graphics library or what?

I am working on a draggable triangle in AS3 and the corners must be interactive. To each corner a bitmap will be attached (in my example for now it's just a name of a city). When dragging a specific corner, the bitmap/cityname (attached to it) should fade in from 0 to 100 alpha. If the bitmap/cityname won't reach 100 of alpha, when Mouse Up, then it should fade back out to 0 opacity. If it does reach 100 alpha when Mouse Up, then it should stay that way. However, if another corner is dragged, then the cityname which is currently at 100 opacity should fade out again. Well I've got the draggable triangle figured, I've got the corners citynames appearing and disappearing when they don't reach 100 alpha. What I can't get to figure out is the last bit - the cityname currently at 100 opacity fading back out to 0 when a different corner is dragged. Hope it's at least a little understandable. I'm not sure my code is perfect (this is my first time in AS3) so don't mind if something is not the way.[code]

I can't see any source code view in catalyst to enable me to fine tune it for each of the 4 corners. How do I specify the roundedness of each corner separately?
