Fix MouseLock for PC Control for delta

local VirtualInputManager = game:GetService("VirtualInputManager")
local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")

-- 【常量预存】
local MOUSE_BUTTON_2 = 1
local isHolding = false

-- 【环境检测函数】
-- 如果设备支持键盘且不支持纯触摸，或者有鼠标，则判定为PC环境
local function IsDesktopEnvironment()
    -- TouchEnabled 虽然在带触摸屏的电脑上也是 true，
    -- 但 KeyboardEnabled 只有在有实体/虚拟键盘映射时才为 true
    -- 最稳妥的判断：有鼠标且有键盘
    return UserInputService.KeyboardEnabled and UserInputService.MouseEnabled
end

-- 【中心点动态缓存】
local cx, cy = 0, 0
local function updateCache()
    local size = workspace.CurrentCamera.ViewportSize
    cx, cy = size.X / 2, size.Y / 2
end
updateCache()
workspace.CurrentCamera:GetPropertyChangedSignal("ViewportSize"):Connect(updateCache)

-- 【强制接管函数】
local function ForceTakeover()
    if not isHolding then
        VirtualInputManager:SendMouseButtonEvent(cx, cy, MOUSE_BUTTON_2, false, game, 0)
        VirtualInputManager:SendMouseButtonEvent(cx, cy, MOUSE_BUTTON_2, true, game, 0)
        isHolding = true
    end
    UserInputService.MouseBehavior = Enum.MouseBehavior.LockCenter
