Graphics.frame_rate应该是改变的游戏画面帧率吧，我希望改变播放视频的帧率
我an做了一个动画是4帧每秒放的，到了rm中播放时明显超过了这个帧率
这是事件中的脚本：

fls = RMFlash.load("3.swf",640,480)
fls.x = 0
fls.y = 0
fls.loop = 1
while true
Graphics.update
# Input.update
fls.update
break if !fls.playing?
# break if Input.trigger?(13)
end
fls.dispose

复制代码

以下是用到的脚本：

class String
CP_ACP = 0
CP_UTF8 = 65001
def u2s
m2w = Win32API.new("kernel32", "MultiByteToWideChar", "ilpipi", "i")
w2m = Win32API.new("kernel32", "WideCharToMultiByte", "ilpipipp", "i")
len = m2w.call(CP_UTF8, 0, self, -1, nil, 0)
buf = "\0" * (len*2)
m2w.call(CP_UTF8, 0, self, -1, buf, buf.size/2)
len = w2m.call(CP_ACP, 0, buf, -1, nil, 0, nil, nil)
ret = "\0" * len
w2m.call(CP_ACP, 0, buf, -1, ret, ret.size, nil, nil)
return ret
end
def s2u
m2w = Win32API.new("kernel32", "MultiByteToWideChar", "ilpipi", "i")
w2m = Win32API.new("kernel32", "WideCharToMultiByte", "ilpipipp", "i")
len = m2w.call(CP_ACP, 0, self, -1, nil, 0);
buf = "\0" * (len*2)
m2w.call(CP_ACP, 0, self, -1, buf, buf.size/2);
len = w2m.call(CP_UTF8, 0, buf, -1, nil, 0, nil, nil);
ret = "\0" * len
w2m.call(CP_UTF8, 0, buf, -1, ret, ret.size, nil, nil);
return ret
end
def s2u!
self[0, length] = s2u
end
def u2s!
self[0, length] = u2s
end
end

buffer, ad = "xxxx", object_id * 2 + 16
RtlMoveMemory_pi.call(buffer, ad, 4); ad = buffer.unpack("L")[0] + 8
RtlMoveMemory_pi.call(buffer, ad, 4); ad = buffer.unpack("L")[0] + 16
RtlMoveMemory_pi.call(buffer, ad, 4); return buffer.unpack("L")[0]
end

然后如何在播放视频的同时显示对话呢（考虑对话不做在视频内的情况），我目前的思路是用开关或者变量，然后在地图上新建一个事件并行处理？但是结果很难控制，貌似会因为播放视频而将文章分成几段，前面一段，播放完了一段。如果可以的话，我希望能和视频同时并行呈现，谢谢大家了，给个解决思路就行。
