RakNetPacket:SetData Synchronous

Replace the bytes in the current packet view before it continues through observers and transport. Use it when you know the exact encoded packet format and need a deliberate rewrite.

Syntax

Luau

RakNetPacket:SetData(data: PacketData) -> ()

Parameters

Call this method with a RakNetPacket receiver. The colon supplies self implicitly; a dot call must pass the receiver explicitly.

Function parameters
Parameter	Type	Description
`data`	`PacketData`	Replacement string, buffer, or dense 1-based array of bytes from 0 to 255.

Argument fields

PacketData fields

Luau

PacketData = string | buffer | {number}

Returns

()

No value.

Usage notes

The RakNetPacket view is valid only during its callback. Save fields or copy Data inside the callback if you need them later.

A packet that continues to the transport can contain at most 268,435,455 bytes. Empty data suppresses delivery. Replacing a real packet requires a protocol-correct payload.

Availability

RakNet is disabled by default. RakNet and raknet are removed when the setting is off; retained references can still call is_enabled().

Example

Luau

if raknet.is_enabled() then
    local connection = raknet.OnPacketSend:Connect(function(packet)
        -- Copy the current bytes without changing their meaning.
        packet:SetData(packet.AsBuffer)
    end)
    task.delay(5, function() connection:Disconnect() end)
end
