#
# CALLS:
#
# Mouse.click?
# 判断鼠标是否真的按下(Ture/False).
# 这个值控制您按下的是左/右键,还是中键
#
# Mouse.press?
# 判断鼠标是否真的按下/保持按下状态
# 这个值控制您按下的是左/右键,还是中键
# Mouse.pixels
# Mouse.pixels
# 这个值返回鼠标所在的坐标(640*480大小),如果鼠标超出游戏画面,这个值为空
#
# Mouse.tiles
# This returns the mouse's screen coordinates in map tiles. Based on the
# system's 20x15 tile size, this returns it in index values (a 0-19 width &
# a 0-14 height). This functions the same manner as Mouse.pixels.
#
# Mouse.set_pos
# This allows you to forcefully position the mouse at an x/y position within
# the game screen by pixel coordinates. Given the game's normal screen width
# of 640x480, adding: Mouse.set_pos(320,240) should position the mouse dead
# center of the gaming window.
#
# Mouse.update
# Add this routine into your update routines to update the mouse position.
# It must be called otherwise you won't get valid mouse coordinates.
