To modify your script so that it intercepts an event when the first argument is "ping" and sets it to 0 before forwarding the arguments to the original `FireServer` method, you can adjust the `hookfunction` implementation. Below is the modified script which achieves this:

```lua

-- Event originated from an Actor Environment
for _, actor in getactors() do
    run_on_actor(actor, [[
        local Event = game:GetService("ReplicatedStorage").UnreliableRemoteEvent
        local mtHook; mtHook = hookmetamethod(game, "__namecall", function(...)
            local self = ...

            if rawequal(self, Event) and getnamecallmethod() == "FireServer" then
                local Args = table.pack(...)

                -- Intercept and modify the arguments if the first argument is "ping"
                if Args[1] == "ping" then
                    Args[2] = 0 -- Set the value to 0
                end

                local Result = table.pack(
                    mtHook(self, table.unpack(Args, 1, Args.n))
                )

                print("Intercepted (__namecall) {" .. Event.Name .. "}:FireServer()", table.unpack(Args, 1, Args.n))

                return table.unpack(Result, 1, Result.n)
            end

            return mtHook(...)
        end)

        local OldFireServer; OldFireServer = hookfunction(Event.FireServer, function(...)
            local self = ...

            if rawequal(self, Event) then
                local Args = table.pack(...)

                -- Intercept and modify the arguments if the first argument is "ping"
                if Args[1] == "ping" then
                    Args[2] = 0 -- Set the value to 0
                end

                local Result = table.pack(
                    OldFireServer(table.unpack(Args, 1, Args.n))
                )

                print("Intercepted (__index) {" .. Event.Name .. "}:FireServer()", self, table.unpack(Args, 1, Args.n))

                return table.unpack(Result, 1, Result.n)
            end

            return OldFireServer(self, ...)
        end)
    ]])
end
```

### Changes Made:
1. **Argument Modification**: Within both the `hookmetamethod` and `hookfunction` implementations, I've added a check to determine if the first argument is `"ping"`. If it is, the second argument (the one that represents the time) is set to `0`.
2. **Print Statements**: The print statements were updated for clarity, displaying the arguments sent to the `FireServer` function.

This will ensure that whenever the `UnreliableRemoteEvent:FireServer` is called with `"ping"` as the first argument, it will be changed to use `0` instead.
