The first becomings of a map editor, by me.
Instructions:
File > Import Tile image
imports an image and adds it to the tileset. checks for double tiles (even if different files). i've provided some images in the images/tiles folder, but you can use there own, provided they're 32x32
choose a layer to draw to.
left mouse = draw selected layer
right mouse = erase on selected layer
you can click & drag to draw/erase to.
these are just robust features for now, and mostly just to get some input and code critique (from wtd mostly
). warning: not commented well, yet
note: it's just the source code and images, and MapEditorFrame.java is the mainclass
