Example

local maxbandwidthbps = get_fflag_value("PhysicsSenderMaxBandwidthBps") -- integer type
if maxbandwidthbps ~= nil then
    print(maxbandwidthbps)
    set_fflag_value("PhysicsSenderMaxBandwidthBps", 0) -- prevents physics packets from reaching the server, causing your character to freeze serverside.
end

local debughumanoidrendering = get_fflag_bool("DebugHumanoidRendering") -- bool type
if debughumanoidrendering ~= nil then
    print(debughumanoidrendering)
    set_fflag_bool("DebugHumanoidRendering", true)
end
