除了@speed*(target_x-x) / Math.sqrt((target_x-x)**2+(target_y-y)**2)这个公式外 还要说我其他的在模仿美兽殿的话-__-~||我实在无法接受 其实最开始我是写成 @sx = (@speed / 2) * (target_x - x) / 100 @sy = (@speed / 2) * (target_y - y) / 100 来着``{/pz} 后来觉得很不妥..看了美兽殿的后觉得美兽殿比较好就直接套用了```{/gg}

因为我不想自己写的东西被蒙上抄袭之名``如果说错话请见谅````````

碰撞.....因为我实在想不到有什么比get_pixel效果还好的方法了```

还有请问一下recject!这个方法的作用是什么?...
我去RUBY中文网看了一下
只看到这个

reject! {|x| ... }
依次将元素传给块进行计算，若结果为真就删除相应元素。




其余的受教了``~``

那个,抱歉了——

1：如果追求绝对的严丝合缝的碰撞，效率最高的仍是get_pixel，但一般来说用不上那么精确，玩过东方系列的人都见过，当子弹穿越角色的身体边缘时并不会中弹，当接触到身体正中时才会掉血，这个是简化为矩形的例子，
但从你所用游戏的图片来看，是标准的三角形，可以事先求得中点，简化为点距离，比矩形还要方便些。

2：

class A
  def move
      return false
  end  
end  
class B
  def move
      return false
  end  
end  
class C
  def move
      return true
  end  
end  

s = [A.new,B.new,C.new]
s.reject! {|x| x.move}

p s ==> [A,B]
