    first_x = 540
    first_y = 347
    frame_x = [523,525,524,528,545,567,591,255,188,171,171,71,175,285,300]
    frame_y = [331,327,327,329,330,357,358,186,182,158,141,76,143,173,268]
    ani_set(id,a,b,first_x,first_y,frame_x,frame_y,150,150)
  end
  #卫忧_游云剑法
  def ani_set_b
    id = 166
    a = 11
    b = 40
    first_x = 540
    first_y = 347
    frame_x = [523,523,525,525,524,524,528,528,545,545,567,567,591,591,255,255,188,188,171,171,171,171,71,71,175,175,285,285,300,300]
    frame_y = [331,331,327,327,327,327,329,329,330,330,357,357,358,358,186,186,182,182,158,158,141,141,76,76,143,143,173,173,268,268]
    ani_set(id,a,b,first_x,first_y,frame_x,frame_y,477,225)
  end
  #唳鹰_待机
  def ani_set_170
    id = 170
    a = 2
    b = 8
    first_x = 364
    first_y = 267
    frame_x = [363,367,366,366,366,367,363]
    frame_y = [267,267,266,266,266,267,267]
    ani_set(id,a,b,first_x,first_y,frame_x,frame_y)
  end
如上脚本，红色的坐标应该是战斗场景里面的坐标吧，这个坐标是怎么来的呢?a 和b又扽别代表什么？
另外求柳柳大人全套教程高清的，网站上的已经都失联了吧！
十分感谢！！！！

你这是局部脚本，看不出来的
