I want to create a GUI tool for a RPG to speed up the math involved in the combat (which was the downfall of the game). I have it roughly spec'ed out, but am not sure where to begin. This will require a database of some type (maybe not a real db), drag and drop (for gear) etc. Note that this tool is NOT a game, but rather a tool to HELP play the RPG.
I am a seasoned old-style programmer, but am relatively new to Java and OOP.
Anyone have any pointers as to where to start?
