说明：需要监听按键或Action时，只需要在返回的table中声明 {KeyName}_Pressed / {KeyName}_Released

例如：

function M:SpaceBar_Pressed()

end

{KeyName}可以参考EKeys的文档：

https://docs.unrealengine.com/4.26/en-US/API/Runtime/InputCore/EKeys/

或者源码：

\Engine\Source\Runtime\InputCore\Classes\InputCoreTypes.h

require "UnLua"

local Screen = require "Tutorials.Screen"

local M = Class()

function M:ReceiveBeginPlay()

local msg =

[[

来试试以下输入吧：

字母、数字、小键盘、方向键、鼠标

—— 本示例来自 "Content/Script/Tutorials.03_BindInputs.lua"

]]

Screen.Print(msg)

-- 数字

"One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine",

-- 小键盘

"NumPadOne", "NumPadTwo", "NumPadThree", "NumPadFour", "NumPadFive", "NumPadSix", "NumPadSeven", "NumPadEight", "NumPadNine",

-- 方向键

"Up", "Down", "Left", "Right",

"Fire", "Aim",
