是这样的，今天闲着无聊自己写了一个功能类似于计算器的小脚本（四则运算，支持先乘除后加减），
那么呢，使用方法如下图

变量51,53,55,57分别代入4个数，变量52,54,56分别代入3个符号。
然后，执行写好的方法，结果代入在100号变量里，最后在事件里输出数值。
那么呢，现在的问题是，确实是经过了计算但是计算结果却不对。
然后呢，我检查过算法了但是并未发现有什么地方不对，希望大家能来帮忙看一下谢谢=w=

你这脚本很多==都写成=了啊…

话说这儿有个非常邪恶的写法。
RUBY 代码复制
  1. def calculate
  2.         str = ""
  3.         (51..57).each do |i|
  4.                  str << $game_variables[i].to_s << " "
  5.         end
  6.         $game_variables[100] = eval str
  7. end

eval is evil!（eval是邪恶的！）

然后eval实在是太邪恶了，所以我就用了比较长但是比较不邪恶的方法来搞：
RUBY 代码复制
  1. def calculate
  2.     a = $game_variables
  3.     arr = [a[51],a[52],a[53],a[54],a[55],a[56],a[57]]
  4.     arr.each_index do |i|
  5.         arr[i] = arr[i].to_sym if arr[i].is_a?(String)
  6.     end    
  7.     loop do
  8.         break if !arr.any?{|i| i.is_a?(Symbol)}
  9.         dm = arr.include?(:*) || arr.include?(:/)
  10.         arr.each_index do |i|
  11.             next unless arr[i].is_a?(Symbol)
  12.             next if dm && ![:*,:/].include?(arr[i])
  13.                 arr[i-1] = arr[i-1].send(arr[i],arr[i+1])
  14.                 arr.delete_at(i + 1)
  15.                 arr.delete_at(i)
  16.                 break
  17.             end
  18.     end   
  19.     $game_variables[100] = arr[0]
  20. end

所以嘛…Ruby这语言还是挺~神奇的。  发表于 2017-1-31 18:00

然后呢数组arr里面如果是[5, :+, 6]这样的话，循环扫描到:+就会执行5.send(:+,6)然后把:+和6从数组内移除掉，这样数组arr里就剩下[11]了  发表于 2017-1-31 17:59

然后用send方法来呼叫运算方法（比如 a = 1 + 2 可以写成 a = 1.send(:+,2)）  发表于 2017-1-31 17:57

下面那个用symbol的方法是比较安全（因为eval很邪恶）。基本上就是使用to_sym方法把"+"变成符号:+之类的  发表于 2017-1-31 17:56
