ray & Click on the 3D object

---

Object click in 3d scene （3d 场景中对象点击）

Event Type: Ray(事件类型：射线检测)

eventSystem:

Mouse	eventType	describe
left	'game.inputMouseDown'	If the ray is detected, return the left click event, otherwise not trigger 如果射线检测到，返回左键点击事件，否则不触发
'game.inputMouseDown.'..this:GetInstanceID()	Same as above, the difference: if the ID of the clicked object is the same as the ID of the listener, the event will be triggered. 同上，区别：如果点击对象的ID和监听者的ID一致，将触发事件.
right	'game.inputMouseDown_1'	If the ray is detected, return the left click event, otherwise not trigger 如果射线检测到，返回左键点击事件，否则不触发
'game.inputMouseDown_1.'..this:GetInstanceID()	Same as above, the difference: if the ID of the clicked object is the same as the ID of the listener, the event will be triggered. 同上，区别：如果点击对象的ID和监听者的ID一致，将触发事件.

example1：

Bind the script to an object and, in run mode, click it with the mouse,Triggered when the left mouse button is pressed

function Start()
    luaEvent:AddEventListener("game.inputMouseDown",this,onInputMouseDown)                luaEvent:AddEventListener("game.inputMouseDown."..this:GetInstanceID(),this,onInputMouseDown1)
end

function onInputMouseDown(info)
    if info:CheckData() then
        local infodata = info.Data
        log('click obj:'..infodata.transform.name)
     end
end

function onInputMouseDown1(info)
    if info:CheckData() then
        local infodata = info.Data
        log('click 1 obj:'..infodata.transform.name)
    end
end
 

function OnDestroy()
    luaEvent:RemoveAllEventListener(this)
end

example 3

log('ray')

local _camera =UnityEngine.Camera.main
function Update()
    if UnityEngine.Input.GetMouseButtonDown(0) then
        log('click')
        local ray = UnityEngine.Camera.main:ScreenPointToRay(UnityEngine.Input.mousePosition)
        local flag, hit = UnityEngine.Physics.Raycast(ray)
        if flag then
           log(hit.transform.name)        
        end
    end
