Today something unexpected happened. I learned something new about RM2K.
What did I learn? In the map editor, when you put tiles in the map, if you hold shift while putting tiles, it will leave out the grass around the tile. For example when you put grass tiles in the water, it will just create square cut off tiles without adding the little transitions of water to land.
This is actually pretty handy, often I found myself in need of water or whatever and I'd always get those grassy lines around it, forcing me to use the selection tool to copy and paste square water tiles.
So it goes to show that even after 8 years you can still learn new things about RM2K.
