触碰Part打开专属商店菜单失败，报错Visible非PlayerGui有效成员

核心错误原因 #

你代码里的关键问题是拼写错误：把玩家对象下的PlayerGui写成了PlayersGui，多了一个字母s导致程序找不到对应成员，从而触发报错。

修正后的基础代码 #

local open = game.Workspace.openPart
local close = game.Workspace.closePart
local frame = script.Parent
frame.Visible = false

local function Shop(otherPart)
    -- 先判断触碰的是玩家角色，避免误触发
    local humanoid = otherPart.Parent:FindFirstChildOfClass("Humanoid")
    if not humanoid then return end
    
    -- 通过角色对象获取对应的玩家
    local player = game.Players:GetPlayerFromCharacter(otherPart.Parent)
    if not player then return end
    
    -- 修正拼写错误：PlayersGui → PlayerGui
    local shopGui = player.PlayerGui:FindFirstChild("Shop")
    if shopGui then
        shopGui.Frame.Visible = true
    end
end

open.Touched:Connect(Shop)

额外优化建议 #

• 避免误触发：原代码直接通过otherPart.Parent.Name查找玩家，容易被场景内其他物件触发，加入Humanoid判断能确保只有玩家角色触发事件。
• 确保GUI存在：如果你的Shop GUI资源不在玩家的PlayerGui内，建议在玩家加入游戏时自动复制GUI到其PlayerGui，可在ServerScriptService添加初始化脚本：

game.Players.PlayerAdded:Connect(function(player)
    local shopGui = script.Shop:Clone()
    shopGui.Parent = player.PlayerGui
end)

• 补充关闭逻辑：你定义了closePart但未实现关闭功能，可补充以下代码：

local function CloseShop(otherPart)
    local humanoid = otherPart.Parent:FindFirstChildOfClass("Humanoid")
    if not humanoid then return end
    
    local player = game.Players:GetPlayerFromCharacter(otherPart.Parent)
    if not player then return end
    
    local shopGui = player.PlayerGui:FindFirstChild("Shop")
    if shopGui then
        shopGui.Frame.Visible = false
    end
end

close.Touched:Connect(CloseShop)
