[help]I'm having trouble with TheInput:GetWorldEntityUnderMouse()

[liuheniw]

AddClassPostConstruct("widgets/hoverer",function(self)
	local old_SetString = self.text.SetString
	self.text.SetString = function(text,str)
        local target = GLOBAL.TheInput:GetWorldEntityUnderMouse()

        if target and target.components then
			print("+++++++++++++++++++++++++++++"..target.prefab.."+++++++++++++++++++++++++++++")
            for name,component in pairs(target.components) do
                count = count + 1
                print("=====No."..count.."=====")
                print("name:"..name)
                -- print("component:"..tostring(component))
            end
        end

		return old_SetString(text,str)
	end
end)

As shown above, I attempted to modify the setString method of the widgets/hoverer in modmain.lua to dynamically retrieve some text description information. However, the target obtained through GLOBAL.TheInput:GetWorldEntityUnderMouse() fails to retrieve its all components.
 
I tried studying the code of a mod named  'insight', which successfully retrieves the "target" using the same method in hoverer.lua and then parses the "target" in modmain.lua. I modified his code by adding print logs and found that it can print all components of the "target". 

However, when I copied his code into my own project, I couldn't achieve the same result. Is there anyone kind enough to help me?

The hoverer widget is running on client side, you don't have access to all components on the client side.

Thank you for your response. I have already resolved this issue in my own way, although it may be a bit sneaky. The code is as follows:

--支持的随从列表
GLOBAL.followers_enum = {
    ["tallbird"] = "高脚鸟",
    ["lightninggoat"] = "伏特羊",
    ["powder_monkey"] = "火药猴",
    ["warg"] = "座狼",
}


--鼠标悬浮在物品上显示信息(仅地面)
AddClassPostConstruct("widgets/hoverer",function(self)
	local old_SetString = self.text.SetString
	self.text.SetString = function(text,str)
		local target = GLOBAL.TheInput:GetHUDEntityUnderMouse()
		if target ~= nil then
			target = target.widget ~= nil and target.widget.parent ~= nil and target.widget.parent.item
		else
			target = GLOBAL.TheInput:GetWorldEntityUnderMouse()
		end
      
      --------随从信息显示--------
      local followers_enum = GLOBAL.followers_enum
      --仅处理拴绳信息
      if target and target.prefab == "leash" then
          for follower, des in pairs(followers_enum) do
              if target:HasTag("leash_"..follower) then
                  str = str .. "\n当前随从：" .. des
              end
          end
      end
      --------随从信息显示--------
      
		return old_SetString(text,str)
	end
end)

------------------------------------显示物品栏拴绳信息---------------------------------------
-- 导入游戏中的库
local ItemTile = GLOBAL.require "widgets/itemtile"
local OldGDS = ItemTile.GetDescriptionString

--修改方法定义，将随从信息塞进去
function ItemTile:GetDescriptionString()
    -- 获取原来的描述字符串
    local oldstr = OldGDS(self)
    local str = ""
    local entity = GLOBAL.Ents[self.item.GUID] --此方法可以获取当前鼠标所选目标的entity
    local followers_enum = GLOBAL.followers_enum

    --仅处理拴绳信息
    if entity and entity.prefab == "leash" then
        for follower, des in pairs(followers_enum) do
            if entity:HasTag("leash_"..follower) then
                str = "\n当前随从："..des
            end
        end
    end

    --这段方法用来将随从信息插入到名字的下一行
    local new_string = ""
    local split_index = string.find(oldstr, "\n")
    if split_index then
        local before_split = string.sub(oldstr, 1, split_index - 1)
        local after_split = string.sub(oldstr, split_index + 1)
        new_string = before_split .. str .. "\n" .. after_split
    else
        new_string = oldstr .. str
    end

    return new_string
end

I discovered that although this 'target' cannot pass 'components', it can pass 'tags'. Therefore, I used 'tags' to transmit my information. Additionally, since the method for displaying item information for 'prefabs' on the ground and in the inventory seemed different, I made modifications in two places to fulfill my requirements. 

Once again, thank you for your response.

嗯，标签在主客机是同步的，这样确实省事
