一共是上面四段脚本
我希望出现的效果在事件标题已经做到了 但是现在转到脚本上有点问题
第一是选项滑动开始的时候开始和退出会同时滚动
第二是如果按住上/下键会出现鬼畜效果
选项滑动在事件中有样子已经提供工程附件
跳过标题脚本已经禁用
望大神指点

呵呵呵……………………
反正这组脚本窝写到这里是不想再修惹~
初始居然会select一下最后一项简直WTF~暂时找不到原因中~

呵呵呵……………………
反正这组脚本窝写到这里是不想再修惹~
初始居然会select一下最后一项简直WTF~暂时 ...

Window_TitleCommand

1.   def select(index)   
   
2.     @command[self.index].refresh(false) if @command   
   
3.     wait(15, self.index) if @command
   
4.     super(index)
   
5.     @command[self.index].refresh(true) if @command
   
6.   end

复制代码

问题出在这个方法的第一句：

1. @command[self.index].refresh(false) if @command

复制代码

当一个command窗口载入的时候，其self.index被设置成了-1，而数组中使用负数作为索引实际上等于倒着往前，于是于是第一次执行select方法的时候所做的事情就是：

1. 
   
2.     结束游戏.refresh(false) if @command   
   
3.     wait(15, self.index) if @command
   
4.     super(1)
   
5.     开始游戏.refresh(true) if @command

复制代码

而refresh方法将结束游戏的@ani_count设置成了0，于是结束游戏自然就会开始update了……

解决方法有很多，例如修改initialize方法变成这个样子：

1.   def initialize
   
2.     super(0, 0)   
   
3.     self.visible = false
   
4.     select_symbol(:continue) if continue_enabled
   
5.     @command[-1].instance_variable_set(:@ani_count, 30000)
   
6.   end

复制代码

同理，select_symbol(:continue) if continue_enabled 这句代码也将造成上面提到的问题，不过既然已经知道问题的来源了修改这个应该不难吧


至于选项鬼畜抖动的……

类似这样把下面这段代码扔进Scene_Title里面，强制等待特效结束后才允许玩家按键就好了（或者玩家每次按键结束后强制等待一段时间也可以）

1. class Window_TitleCommand
   
2.   def cursor_movable?
   
3.     result = super
   
4.     return false unless result
   
5.     @command.each{|c| return false if c.m5_effect?}   
   
6.     true
   
7.   end  
   
8. end
   
9. class Window_TitleSub  
   
10.   def m5_effect?
    
11.     return @ani_count < COUNT   
    
12.   end
    
13. end

感谢喵5前辈啦 而且这个标题特效只会出现两次啦…… @cinderelmini
