Simple Tiling Sprite Class in AS3

After writing last night’s class, scalingBars, I decided to make it a little easier on myself to tile bitmaps across the screen. I wrote a simple class that when given either a BitmapData object or a path to an image file (as a String), class will tile the image x pixels in width and y pixels in height. This is great for backgrounds or window bars or box sides, etc. Here’s the usage:

var bar:tile = new tile("pathToImageOrBitmapDataObject", 100, 150);

The previous code will grab an image from “pathToImage” [either relative or absolute, but remember security!] and then tile it 100 pixels wide by 150 pixels tall. Simple. Now let’s say you wanted to resize it:

bar.resize(20, 40);

That code will re-tile the image to 20 pixels by 40 pixels. Next on my list of upgrades is to allow reloading of different images. Shouldn’t be too hard.
