What's the best way to rotate a rectangle around it's own center point? The only way I can find to do it is to create my own rectangle such that its center corresponds to 0,0. Then I can move my rectangle elsewhere (with x and y) and it rotates around its center.
Code:
myRect = new Sprite();
myRect.graphics.beginFill(0x009999, 0.6);
myRect.graphics.moveTo(-50,-50);

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 draw a rectangle i should see a little bold circle to indicate a perfect rectangle, I seemed to lost mine, can somebody please tell me how to get it back!
View 2 RepliesI 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.
View 0 RepliesI 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?
how to respond when a rectangle hits another rectangle? I already know how to detect the collision, I just don't know how to respond to it. I'm just trying making a simple side-scrolling platform game where I have platforms I can walk on and bump against on all sides. I have searched everywhere and just can't find the tutorials I'm looking for.

In Flash CS4, when I draw a rectangle (or circle, or anything) with a color that has 0 alpha, nothing is drawn. Also, if I select a piece of drawing and change the color to 0 alpha, the drawing (e.g. rectangle) disappears!I know I can draw a non-transparent rectangle, convert it to movie clip and set the movie clip's alpha to 0, but I'd like to avoid this.

View 1 RepliesI have two options and I want to know whats faster. I have a pool of 1000 sprites objects in as3 on screen. When its needed each sprite has to resize itself. I can
1- Make each sprite a simple container to use graphics to draw a rectangle, that is, call a 'spriteInstance.graphics.' ,draw the rectangle and on each 'refresh', I do graphics.clear and redraw the rectangle but with the new size, this for each sprite.
or
2- Create each sprite with a border and on each refresh, resize it
Whats better?
I was working on some blitting code today and after profiling it found that I was creating 1000s of new rectangles. I was shocked because I only had 1 or 2 different new Rectangle() calls or I was using the .rect property of BitmapData.
I started commenting out huge swathes of code until I was left with this code in my sprite class:
canvas.bitmapData.copyPixels(_bitmapData, _bitmapData.rect, destination, null, null, true);
I cached the result of _bitmapData.rect at object creation and my thousand of new rectangle calls were suddenly gone from the profiler.
Why the heck would BitmapData.rect create a new rectangle? Is there a way to check the core libraries or something and confirm this is true?
I have a normal rectangle shape in flash. Id like to change the fill color of it using code, so I can use flashvars and be able to change the color of the shape with a few HTML adjustments.All I need to know is how to change the fill color of the shape. I've got the flashvars sorted.

I am exporting SWF to flex and drawing it there. Do not scaling it in run time, just need few sets of scales.
With the select tool, I placed my mouse over the edge & it changed to the little curve sign, but when I dragged it, it just moved the rectangle. Same thing when using the transform tool.

for the past two weeks I've been working on coming up with a collision detection system for my game in flash CS4. No matter what I try for some reason I just can't seem to do it, and I don't know how to fix it. This has never been an issue for me, I would even settle for basic rectangle to rectangle collision if I could, but no matter what I do I end up screwing it at all up. Somehow the collision detection either doesn't work at all, works for one side and jumps the guy through the wall on any other side or I think at one point it worked for two sides as long as I didn't hold down more than one movement key.
I've constantly scrapped what I've done over and over, right now I have no source code to present. I'm totally lost and confused, and my deadline for getting this done is today in a few hours. I really wanted to figure this out on my own but honestly I just don't see what I can do, I've got sphere to sphere collision detection working perfectly for my player and other spheres, but the walls are squares lined up to form long rectangles, and I just can't seem to get it to work. I'm dynamically loading the square-wall blocks as tiles to form a dynamically loaded map, and then I'm iterating through each individual block to determine if collision has occurred with the player. I think somehow I'm not managing the results right, or maybe I somehow need to be able to determine which direction the player hit the wall from, but I just don't know how to do it.
I've been staring at the screen for the past 3 hours trying to work something out but nothing is coming to me, example from a flash-type game or something similar I would be very grateful! (I've done this countless times in C++, C#, and java. I don't get what is going on in flash :-(((( )
I burnt so much time on a costume made component which extends NumericStepper.Adobe should be ashamed..

Im probably overlooking something simple, but when I try to draw a rectangle Flash is automatically applying a corner radius. I've tried resetting the options in the Properties Inspector, which resets to the default, but soon as a draw a shape it goes right back to a random radius.
View 4 RepliesI'm trying to make a modal pop up in my Flash application, not unlike the ASP.NET version seen here. I've already got the dialog box made, but I'm trying to add a semi-transparent gray rectangle over everything behind the pop-up, again like the one used in ASP.NET. Is there a way to do this in ActionScript? It needs to be semi-transparent, not fully, so you can still partially see what's behind it. I'm assuming you could apply this property to a Shape class somehow.

m.ty -= point.y;
m.rotate(angleDegrees*(Math.PI/180));

I Have also povided the dragging feature so that one can drag the text field. The problem is when i rotate the text field say 45 degrees and then i drag it to other position now if i rotate the text field again it is not rotating about its center or origin, it rotates about some other point that is calculated by the same method ---mc.x+ mc.width / 2,mc.y+ mc.height
I remember i realised this ages ago, but never really needed anything with it till now. I think it was after flash mx that imported images, when rotated or scaled loose quality horribly.
