A standard recommendation is to separate view from controlling code. A good way to achieve this in Flex is to have a mxml class that contains nothing but view and to move all the controlling code to a superclass.

LoginScreen.mxml

<p:LoginScreenClass 	xmlns:mx="http://www.adobe.com/2006/mxml"  xmlns:p="path.to.LoginScreenClass.*"  />

LoginScreenClass.as

package path.to.LoginScreenClass
{
	import mx.containers.VBox;
	public class LoginPanelClass extends VBox {}
}

Exploration of Blend effects and how they apply on a cutout masking an image.

Something I had wanted to figure out. The LandscapeMapEditor on wondefl provided all that was required to get started. The original code was under a MIT license and that license is therefore carried on.

This is a strictly actionscript project. Label and InputText controls come from the minimalComps library by Keith Peters.

NOTE. It looks like I changed the controls for the diameter of the circle. Use the up arrow and down arrow to increase/decrease the radius of the circle.

Background Information

Generating Random Fractal Terrain by Paul Martz. A good overview of the theory behind terrain generation (midpoint displacement and other techniques).

Actionscript 3

An extensive list of links on terrain rendering in Flash by Bruce Jawn

Impressive ones at wonderfl

• Terrain flyer.
• Terrain on 3D globe, with light source
• bumpy planet
• Landscape Map Editor (it takes a bit of time to figure the key controls. Left and right arrows to change the size of the circle, up or mousedown to add terrain, down to remove, z to toggle circle random movements).

Code found on wondefl can be executed within Flex Builder. Create a project File > New ... > Actionscript Project. Make sure that you have the Flex SDK 3.5 installed and that this project makes use of it (Project > Properties > Actionscript Compilers > Flex SDK Version). If Base64Decoder is required for the project to run, download the SDK source for 3.5. Locate mx.utils.Base64Decoder. In your project, create a folder mx/utils/ and copy there the class Base64Decoder. Delete the line that define the resource metadata as this requires the Flex framework (not included in an Actionscript project). Run your project,

For a mini AIR project I had some issue with sandbox security violation warnings that kept coming up any time I was using DragManager on images for which the source had been set to some locally held images (within the User Directory).

To bypass these warning, it is required to load the bytes into a bitmap and to get the image component display the bitmap. Code below.

Free to re-use tilesets can be found on the Reiners website. As per Reiners Readme Page "All the graphics and meshes are freeware. Even for commercial Games. I just want my name in the Credits in the commercial case: Reiner "Tiles" Prokein. You can modify my graphics in every needed way to fit it to your needs: size, colour, fileformat, etc., you can reuse the textures ... . "

Further resources are listed on the widged wiki, under game content and game tiles. (Note however that these links were collected 2-5 years ago, some may be broken)

Tile manipulation via a SpriteSheet (grid that defines the location of the tiles) and TileSet (combination of grid and image data) abstraction

/**
 * Get the bitmap for a tile at a given [row,column]
 * @param rowId row index (starts at 0) 
 * @param columnId column index (starts at 0) 
 */
public function getTileBitmap(rowId:int,colId:int):Bitmap
{
   var bitmapData:BitmapData = new BitmapData(_sheet.tileWidth,_sheet.tileHeight, false, 0xFFFFFF);
   bitmapData.copyPixels(_bitmap.bitmapData, _sheet.getTileRectangle(rowId, colId), new Point(0, 0));
   return new Bitmap(bitmapData);
}
