Simple Function Detour Example

--[[
Probably a very popular method of detouring, very simple, and effective if run before localization or no localization is used.
]]--

local Detours = {} -- Our Detours table, we are going to store our detoured functions here.
local ProtectedFiles = {
    "aimbot.lua",
    "esp.lua"
}
local function DetourFunction(originalFunction, newFunction) -- Function that handles the detouring for us
    Detours[newFunction] = originalFunction -- Save the old function
    return newFunction -- We want to return our new, detoured function
end

file.Read = DetourFunction(file.Read, function(fileName, path) -- For this example, we are going to be detouring file.Read, this function has the arguments of string filename and string path
    for k,v in next, ProtectedFiles do
        if (string.find(filename, v) then -- We want to protect our files
            return "haha not today bitchboy" -- Return an intimidating string so they know you're not messing around
        end
    end

    return Detours[file.Read](fileName, path) -- Return the original function of file.Read so files that you dont care about can still be read by addons that use things like configs, etc.
end)
