我用数组做了个任务系统，加第二个任务时就出现了TypeError，我想，可能是数组加入新单元方法不对。
脚本：

#--------------------------------------------------------------------------
# ● 生成新任务（在Scene_Task的内部使用）
#--------------------------------------------------------------------------
def new_task(name, help, difficulty = 1, gold = 0, items = nil, weapons = nil, armors = nil, item_num = 1, weapon_num = 1, armor_num = 1)
# 实例变量的改变
@new_task_name = name
@new_task_help = help
@new_task_gold = gold
@new_task_items = items
@new_task_weapons = weapons
@new_task_armors = armors
@new_task_item_num = item_num
@new_task_weapon_num = weapon_num
@new_task_armor_num = armor_num
@new_task_difficulty = difficulty
$game_taskdata.tasks += 1
# 保存数据（载入数组）
if $game_taskdata.task_name[0] == ""
$game_taskdata.task_name = [@new_task_name]
$game_taskdata.task_command_name = [@new_task_name]
$game_taskdata.task_help = [@new_task_help]
$game_taskdata.task_gold = [@new_task_gold]
$game_taskdata.task_items = [@new_task_items]
$game_taskdata.task_weapons = [@new_task_weapons]
$game_taskdata.task_armors = [@new_task_armors]
$game_taskdata.task_item_num = [@new_task_item_num]
$game_taskdata.task_weapon_num = [@new_task_weapon_num]
$game_taskdata.task_armor_num = [@new_task_armor_num]
$game_taskdata.task_difficulty = [@new_task_difficulty]
else
$game_taskdata.task_name[$game_taskdata.tasks] = @new_task_name
$game_taskdata.task_command_name[$game_taskdata.tasks] = @new_task_name
$game_taskdata.task_help[$game_taskdata.tasks] = @new_task_help
$game_taskdata.task_gold[$game_taskdata.tasks] = @new_task_gold
$game_taskdata.task_items[$game_taskdata.tasks] = @new_task_items
$game_taskdata.task_weapons[$game_taskdata.tasks] = @new_task_weapons
$game_taskdata.task_armors[$game_taskdata.tasks] = @new_task_armors
$game_taskdata.task_item_num[$game_taskdata.tasks] = @new_task_item_num
$game_taskdata.task_weapon_num[$game_taskdata.tasks] = @new_task_weapon_num
$game_taskdata.task_armor_num[$game_taskdata.tasks] = @new_task_armor_num
$game_taskdata.task_difficulty[$game_taskdata.tasks] = @new_task_difficulty
end
end

复制代码

class Game_TaskData
attr_accessor :task_name
attr_accessor :task_command_name
attr_accessor :task_help
attr_accessor :task_gold
attr_accessor :task_items
attr_accessor :task_weapons
attr_accessor :task_armors
attr_accessor :task_item_num
attr_accessor :task_weapon_num
attr_accessor :task_armor_num
attr_accessor :task_difficulty
attr_accessor :tasks
def initialize
@task_name = [""]
@task_command_name = [""]
@task_help = [""]
@task_gold = [0]
@task_items = [nil]
@task_weapons = [nil]
@task_armors = [nil]
@task_item_num = [0]
@task_weapon_num = [0]
@task_armor_num = [0]
@task_difficulty = [1]
@tasks = 0
end
end

思路不变，让它保留过去的任务就只能这种思路了，但是总会出错。数组如何加入新单元？

我没看脚本只说方法
a = []
a[0] = "123"
a[3] = "456"
p a # 现在a是["123", nil, nil, "456"]

b = []
b << "123" << "456"
p b # 现在b是["123", "456"]

因为那是任务系统，所以框内不是恒量，而是变量，但是总是TypeError。

@xxxx1 = "123"

改为@xxxx1 = "123"

class Game_Temp
attr_accessor :xxxx1
attr_accessor :xxxx2
attr_accessor :xxxx3
alias initialize_old initialize
def initialize
[url=home.php?mod=space&uid=349002]@xxxx1[/url] = "123"
@xxxx2 = "234"
@xxxx3 = "345"
initialize_old
end
end
array = [$game_temp.xxxx1, $game_temp.xxxx2, $game_temp.xxxx3]
p array # => ["123", "234", "345"]
$game_temp.xxxx1 = "000"
$game_temp.xxxx2 = "111"
$game_temp.xxxx3 = "222"
array = [$game_temp.xxxx1, $game_temp.xxxx2, $game_temp.xxxx3]
p array # => ["000", "111", "222"]
# 场景中
# （命令窗口）字符123，234，345
class Game_Temp
attr_accessor :xxxx1
attr_accessor :xxxx2
attr_accessor :xxxx3
alias initialize_old initialize
def initialize
@xxxx1 = "123"
@xxxx2 = "234"
@xxxx3 = "345"
initialize_old
end
end
class Xxxx
def main
array = [$game_temp.xxxx1, $game_temp.xxxx2, $game_temp.xxxx3]
@command = Window_Command.new(160, array)
Graphics.transition
loop do
Graphics.update
Input.update
update
if $scene != self
break
end
end
Graphics.freeze
@command.dispose
end
def update
@command.update
if @command.active
update_command
return
end
end
end
# -------
$game_temp.xxxx1 = "000"
$game_temp.xxxx2 = "111"
$game_temp.xxxx3 = "222"
# 再次 $scene = xxx
$scene = Xxxx.new
# （命令窗口）字符000，111，222

我估计这样行不通的……实在不明白什么意思……思路又完全变了……

1.请详细的给出报错信息
2.您这个方法我只能表示呵呵，好高级的方法，本来还想改一下后来发现真是a waste of time
3.请不要这样随便的玩坏类，玩坏数组，玩坏了也请不要赖在他们身上

$game_taskdata.task_name = [@new_task_name] 这是神马奇怪的写法你既然已经申明了 task_name是个数组你又给他重新换了个新数组？
数组里加新元素用push就行了
Game_TaskData里 @task_name = [""] 你给首地址弄个空字符串做啥你只要申明这是个数组就行了 RUBY是弱类型语言 @task_name =[]这样足矣
然后$game_taskdata.task_name.push @new_task_name 其他地方不解释了反正就按这思路

$game_taskdata.task_name = []
$game_taskdata.task_name.push(@new_task_name)#里面可以加", @其他变量......"
p $game_taskdata.task_name
