how would I get the coordinates of a player? because I cant edit a map im using it for, i need to make it use player coordinates. If a player is at the coordinates, a say cmd will be functional to them. Also, how would i get if a player is WITHIN a area of the map, as in would i have to get the coordinates for 4 corners of an imaginary square, and then make a plugin that says if blah is in blah?
