诡异的循环问题

zh99998

Path = ["", "d:\\rpg\\RPG Maker XP\\RGSS\\Standard/"]
ext = ["png", "jpg", ""]
filename = "Graphics/tilesets/001-grassland01"
    Path.each do |path|
      ext.each do |ext|
        filename.insert(0, path)
        filename += "." + ext unless ext.empty?
        p filename,FileTest.exist?(filename)
        return filename if FileTest.exist?(filename)
      end
    end

只p三次，并且第二行都是false，正常应该是p出4次，第四个是true才对

自己解决了- -
变量名的冲突

chenyin

Path = ["D:/o/"]
ext = [".png", ".jpg", ""]
filename = "1"
for l in Path
  for i in ext
    if FileTest.exist?("#{l}#{filename}#{i}")
    p ("#{l}#{filename}#{i}")
    end
  end
end
