我正在为角色扮演游戏创建一个点购买方法，玩家可以在其中修改角色的能力得分。if当输入应该正确时，我的条件没有得到满足，我不知道为什么。
$player = {
abils: {str: 10, con: 10, dex: 10, wis: 10, int: 10, cha: 10}
}
def abil_point_buy(x)
points = x
puts "<Add or subtract points from each ability (e.g. +2 STR, -1 CHA, etc.)>"
loop do
puts "<You have #{points} points remaining. Current ability scores:>"; print "<"
$player[:abils].each { |abil, pts| print "#{abil.upcase}: #{pts} "}; puts ">"
input = gets.chomp.downcase
abil_check = $player[:abils][input.gsub("^a-z", "").to_sym]
if abil_check && input.match?(/\d/) #checks if input contains a number and an ability score
mod = input.gsub(/\D/, "") #determines amount to modify ability score by
pos_or_neg = !input.include?('-') #determines if mod will be positive or negative
$player[:abils][abil_check] + mod.to_i * (pos_or_neg ? 1 : -1) #adjusts selected ability score by mod
pos_or_neg ? points - mod : points + mod
break if points == 0
else
puts "Something is wrong with your input."
end
end
end
还将感谢改进我的代码的一般提示。
