Lua - 执行存储在表中的函数 [英] Lua - Execute a Function Stored in a Table

问题描述

我能够将函数存储到表中。但是现在我不知道如何调用它们。决赛桌将有大约100个电话，所以如果可能的话，我想像在foreach循环中一样调用它们。感谢！

I was able to store functions into a table. But now I have no idea of how to invoke them. The final table will have about 100 calls, so if possible, I'd like to invoke them as if in a foreach loop. Thanks!

以下是表格的定义：

Here is how the table was defined:

game_level_hints = game_level_hints or {}
game_level_hints.levels = {}
game_level_hints.levels["level0"] = function()
    return
    {
        [on_scene("scene0")] =
        {
            talk("hint0"),
            talk("hint1"),
            talk("hint2")
        },
        [on_scene("scene1")] =
        {
            talk("hint0"),
            talk("hint1"),
            talk("hint2")
        }
    }
end

Aaand函数定义：

Aaand the function definitions:

function on_scene(sceneId)
    -- some code
    return sceneId
end

function talk(areaId)
    -- some code
    return areaId
end

编辑：

我修改了函数，使它们有更多的上下文。基本上，他们现在返回字符串。 我希望发生的事情是，在调用函数结束时，我将有一个包含所有这些字符串的表（最好是levels表）。

I modified the functions so they'll have a little more context. Basically, they return strings now. And what I was hoping to happen is that at then end of invoking the functions, I'll have a table (ideally the levels table) containing all these strings.

推荐答案

asd = game_level_hints.levels["level0"]()

现在， asd 包含我需要的区域字符串。尽管理想情况下，我打算能够访问如下数据：

Now, asd contains the area strings I need. Although ideally, I intended to be able to access the data like:

asd[1][1]

访问它：

accessing it like:

asd["scene0"][1]

检索区域数据就足够了。我只需要解决按键问题。

to retrieve the area data would suffice. I'll just have to work around the keys.

谢谢，伙计们。
