GameTooltip HookScript OnTooltipSetItem does not take effect in other people's display

[GoMateoGo]

I have encountered a troublesome problem. This problem is most likely not AIO's problem, I hope you can get help.

server file name: myaddon_server.lua

• Lua Code:

local AIO = AIO or require("AIO")
 
local ItemStateHandler = AIO.AddHandlers("ItemStateUI", {})
 
-- Receive messages from the client
function ItemStateHandler.GetItemBonus(player)
    -- Handling messages here....
 
    AIO.Handle(player, "ItemStateUI", "ModifyState", 10000) -- Send the message back to the client side
end

client file name: myaddon_client.lua

• Lua Code:

local AIO = AIO or require("AIO")
 
if AIO.AddAddon() then
    return
end
 
local ItemStateHandler = AIO.AddHandlers("ItemStateUI", {})
 
-- global GameTooltip Obj
local globalItemObj = nil
local function ModifyShow(tooltip)
    if not tooltip then return end
 
    local _, ItemLink = tooltip:GetItem()
 
    if not ItemLink then
        return
    end
 
    local typ, _, _, _, _, _, _, _, _, _ = strsplit(":", string.match(ItemLink, "item[%-?%d:]+"))
    if typ ~= "item" then
        return
    end
 
    globalItemObj = tooltip
 
    AIO.Handle("ItemStateUI", "GetItemBonus"); -- req server
end
 
GameTooltip:HookScript("OnTooltipSetItem", function(self)
    --getglobal("GameTooltipTextLeft1"):SetText("This is the newly added content.")
    ModifyShow(self)
end)
 
ItemRefTooltip:HookScript("OnTooltipSetItem", function(self)
    ModifyShow(self)
end)
 
 
function ItemStateHandler.ModifyState(player, serverStr)
    if not globalItemObj  then return end
 
    local _, ItemLink = globalItemObj:GetItem()
 
    if not ItemLink then
        return
    end
 
    local typ, _, _, _, _, _, _, _, _, _ = strsplit(":", string.match(ItemLink, "item[%-?%d:]+"))
    if typ ~= "item" then
        return
    end
 
    for i = 1, globalItemObj:NumLines() do
        local tooltip = getglobal(globalItemObj:GetName() .. "TextLeft" .. tostring(i)):GetText()
        local tmpStr = tooltip .. serverStr
        getglobal(globalItemObj:GetName() .. "TextLeft" .. tostring(i)):SetText(tmpStr)
    end
end

At this point, when using the two previously created characters to view their own items, GameToolpoint is called, and everything works fine, but when viewing each other's items through the characters, the item text does not change.

However, the ItemRefToolTip object is valid. There are always changes.

The above are the problems encountered when using GameToolpoint.

To solve this problem, I added some print information. The code is as follows:

• Lua Code:

GameTooltip:HookScript("OnTooltipSetItem", function(self)
    --getglobal("GameTooltipTextLeft1"):SetText("This is the newly added content.")
    print("this is gameTooltip", self)
    ModifyShow(self, self:GetName())
end)
 
 
function ItemStateHandler.ModifyState(player, serverStr)
    if not globalItemObj then return end
 
    local _, ItemLink = globalItemObj:GetItem()
 
    if not ItemLink then
        return
    end
 
    local typ, _, _, _, _, _, _, _, _, _ = strsplit(":", string.match(ItemLink, "item[%-?%d:]+"))
    if typ ~= "item" then
        return
    end
 
    print("this is globalItemObj", globalItemObj, globalItemObj:GetName())
    for i = 1, globalItemObj:NumLines() do
        local tooltip = getglobal(globalItemObj:GetName() .. "TextLeft" .. tostring(i)):GetText()
        local tmpStr = tooltip .. serverStr
        getglobal(globalItemObj:GetName() .. "TextLeft" .. tostring(i)):SetText(tmpStr)
 
        local printStr = getglobal(globalItemObj:GetName() .. "TextLeft" .. tostring(i)):GetText()
        print("after str:", printStr)
    end
end

The result after str is indeed appended, but it is not displayed (when character 1 views character 2 items, the tooltip display of character 1 is not updated.)

Thank you for listening to my long-winded. Any help I really appreciate :)
