This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
today I was reading about isometric and hexagonal maps for games( Isometric and Hexagonal maps ). Well personally I'm interested in hexagonal maps, but both of them had something similar. It is said, I quote: "Since both Iso and Hex tiles are contained in overlapping rectangles, you MUST USE BITMASKS!", well I don't understand why use bitmasks when I can create *.png image with transparency?
And another thing if this bit masking is really needed, how do I perform bit blitting in java, what methods or which class should I use?
