Description

Appends an integer - a whole number - to the current net message. Can be read back with net.ReadInt on the receiving end.

Use net.WriteUInt to send an unsigned number (that you know will never be negative). Use net.WriteFloat for a non-whole number (e.g. 2.25).

Arguments

number integer

The integer to be sent.

Arguments

number bitCount

The amount of bits the number consists of. This must be 32 or less.

If you are unsure what to set, just set it to 32.

Consult the table below to determine the bit count you need.

Examples

Example

Sends the server the client's age.

--Client
function SendAge()
     net.Start("SendAge")
     net.WriteInt(3, 3)  -- Only 2 bits are needed to store the number '3', but we add one because of the rule.
     net.SendToServer()
end

--Server
util.AddNetworkString("SendAge")

local function GetAge(len, ply)
     local age = net.ReadInt(3) -- use the same number of bits that were written
     print("Player " .. ply:Nick() .. " is " .. age .. " years old."
end
net.Receive("SendAge", GetAge)

Output:

Player <name> is 3 years old.
