I've worked a little on my game engine this weekend.  I went ahead and added some functionality that I felt was essential:  graphics scaling.  That includes mostly the ability to display sprites at smaller or larger dimensions.  Getting that done wasn't terrible, for the most part.

However, I more importantly wanted to be able to scale the display.  My work is Java applet-based; so the display doesn't dynamically change size like a windowed program would.  But, I wanted this functionality to be there for later.  Another benefit I get from doing so is being able to have a small area to draw on and then scale it up to something that is easily visible.  This approach is more efficient than scaling up all the smaller sub-images on a large display.

Plus, this approach works great for remaking classic 8-bit games that use something like a 320 x 240 resolution.  As always, go ahead and check out the progress at:
