Actionscript 3 :: Flex - Trying To Draw A Box Without Mxml

Aug 14, 2010

I'm trying to draw a box with actionscript 3 and flex 3.5. First a few things:

1) I am not using any IDE at all, just notepad and flex
2) I am not using any mxml file at all (yes this is possible with as3 apparently)
3) I am not using inheritance ie I'm not using an extends on my classes, I'm trying to get this particular bit of code to work only through composition

Anyway this is the code itself (the file name is MAIN.as):

ActionScript 3.0 :: Position Graphics In A Circular Pattern ?

Jan 13, 2010

how to position graphics in a circular pattern and they space out evenly depending on how many graphics are in a given array.So now, I want to be able to rotate the graphics in a clockwise or counter-clockwise pattern (not a sprite container that holds all of the graphics, but the graphics themselves.)

Code:
private function weaponChange(e:KeyboardEvent):void {
if(e.keyCode == LEFT_KEY1 || e.keyCode == LEFT_KEY2 || e.keyCode == DOWN_KEY1 || e.keyCode == DOWN_KEY2) {
for(var i:uint = 0; i < _weaponSymbols.length; i++) {[code]....

So this gets each graphic to the next location just fine. Now notice what I have in red... I want the graphics to animate along the parameter of the circle. All I need to do that is to identify the x,y coordinates between the two graphics. I can just subtract the y of one graphic from another... the x is something I have no idea how to do...

Flex :: Draw A Circle Inside Border Container Using Graphics Object?

Apr 5, 2011

My basic requirement is to draw a circle inside a BorderContainer with the layout set to BasicLayout.I run this method in the CREATION_COMPLETE event of the BorderContainer object.[code]I know I must be missing something VERY basic here. Can I just draw like this OR should I draw in some other event? I know that I can create a Ellipse object and easily add it to the border container but I would like to know how I can do this using the graphics object.

Flex :: Draw Multiple Graphical Objects In A Spark ItemRenderer Using MXML?

Apr 26, 2011

I would like my spark ItemRenderer to be able to render a varying number of graphical objects that depends on the user input. As an example, let's say that I want to render a set of ellipses on a line.I've been using MXML for my most recent batch of ItemRenderers and have loved every minute of it, but I'm not sure how to accomplish the above goal with an MXML IR. In Actionscript I can acquire the list of ellipses locations and draw them programmatically in the updateDisplayList method. Is there an equivalent in MXML?

Flash - Draw A Bitmap In Graphics-Object At Any Position?

Mar 30, 2011

Is it possible to draw a Bitmap to a Graphics-Object like

this.graphics.beginBitmapFill(bitmapData, matrix, false);
this.graphics.drawRect(0, 0, w, h);
this.graphics.endFill();

with an offset?

A simple moveTo(x, y) call before beginBitmapFill does not work :/ Neither does changing the x and y value of drawRect... (That just seems to have the same effect as an translation with the matrix...) Additionally I don't want do draw that thing in a separate Graphics-Object and add that one into the other...

I need draw rectangle with two circle holes inside. The problem is in circles interception. I want them to join together and cut from background, but they seems to be XORed:

At first I tried drawRect and DrawCircle:

graphics.beginFill(0, 0.5);
graphics.drawRect(0, 0, width, height);
graphics.drawCircle(width/2, height/2, 50);

[Code].....

here getCirclePath returns object with points to draw polygon which looks like circle. Also I tried different combinations of GraphicsPathWinding constants, but no luck.

Flex :: Extending Mxml Component With From Another Mxml Component With Visual Child Supported?

May 18, 2011

I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.

What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?

if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?

Actionscript 3 :: Draw Transparent Graphics Onto Transparent BitmapData?

Feb 5, 2012

I'm trying to draw PNGs onto BitmapData that is transparent.

I create my BitmapData like this (using ARGB for the color):

new BitmapData(width, height, true, 0x00000000);

And clean it by using the same ARGB value:

bitmapData.fillRect(bitmapData.rect, 0x00000000);

When I use copyPixels() to draw graphics onto the cleaned BitmapData, I get this result:

If I don't use ARGB for the BitmapData color, it works fine:

But I have to specify a solid fillColor, meaning I can't render what's behind the Bitmap.

How can I make my BitmapData transparent, but not have the above occur?
