Capture keyboard key event

Method 1

Get keyboard keys through events to avoid detection per frame

Complete button push, only do it once per frame, if there is no monitoring, do not do any message push

Method 2 （ UnityEngine.Input.GetKeyDown）

means that each script is detected in the update, which is not friendly

方法1

通过事件获取键盘按键，避免每帧检测

完成按键推送，每帧只做一次，如果没有监听，不做任何消息推送

方式2，

意味着每个脚本都在update中做检测，这是不友好的

eventType	Combining 'keyboard' and UnityEngine.Keycode value 'keyboard.Space' 'keyboard.A' 'keyboard.B'

example

--method 1
function Start()
    luaEvent:AddEventListener('keyboard.Space',this,OnKeyDown)
end

function OnKeyDown(info)
    print("method 1: Down Space")
end

function OnDestroy()
    luaEvent:RemoveEventListener('keyboard.Space',this)
end

--method 2
function Update()
    if UnityEngine.Input.GetKeyDown(UnityEngine.KeyCode.Space) then
        print("method 2: Down Space")
        end
end

--close ui & set renderscale

scene id:761 、779

--隐藏UI
local record=newList(UnityEngine.GameObject)
local isShowUI =true

function Start()
    FindCanvas()
    luaEvent:AddEventListener('keyboard.V',this,OnKeyDownV)
    luaEvent:AddEventListener('keyboard.B',this,OnKeyDownB)
end

function OnKeyDownB(info)
       print("method 1: Down V")
    local tab=  GetTable('testRenderScale')
    print(tab)
    if tab then
       tab.ShowOrHide()    
    end
end

function OnKeyDownV(info)
    print("method 1: Down B")
    if isShowUI then
        isShowUI =false
    else
        isShowUI =true
    end
    SetUIState(isShowUI)
end

function FindCanvas()
    local objs=   GameObject.FindObjectsOfType(typeof(UnityEngine.Canvas))

    for i = 0, objs.Length-1 do
        --print(objs[i].name)
        local canvas = objs[i]
        local pName = canvas.transform.parent.name
        if pName ~='InputManager' and pName ~='Fps' then
            record:Add(canvas.gameObject)
        end
    end
end

function SetUIState(isShow)
    for i = 0, record.Count-1 do
        record[i]:SetActive(isShow)
    end
end


function OnDestroy()
    luaEvent:RemoveEventListener('keyboard.V',this)
    luaEvent:RemoveEventListener('keyboard.B',this)
end
