unit selection problem

Unit selection doesn't work properly. Pygames event.pos returns a tuple of the coords within the current window, so it's not possible to select units outside of the top left corner.

self.map_layout = map_constructor("map.png", 2400)
self.object_counter = len(self.map_layout.all_map_objects)
map_textures = get_sprites( (48, 4 ,"spritesheet.png" , (0, 0) )
self.collision_map = []

# defines all map objects in readable format
self.map_sprite_list = {
'floor_red' : map_textures.sprites[0],

You forgot to include spritesheet.png in your message. Seriously,
finding the problem yourself, otherwise post the complete compilable
example here.
