Okay, often I see the function called with three arguments: x, y, and some number - often 0 or 1.
Now, x and y I can kinda figure out (coords of the tile in question), but what's the 0 or 1 represent?
Speaking of which, where are the cover values defined? Let's say I wanted to make forests 85 cover and increase the fortify bonus of a pill box to 8x - where would I go to do this?
