<function name="Receive" parent="net" type="libraryfunc"> <description> Adds a net message handler. Only one receiver can be used to receive the net message. You can use the `net.Read*` functions within the message handler callback. <note>The message-name is converted to lower-case so the message-names "`BigBlue`" and "`bigblue`" would be equal.</note> <warning>You **should** put this function **outside** of any other function or hook for it to work properly unless you know what you are doing! You **must** read information in the same order as you write it. Each net message has a length limit of **64KB**!</warning> </description> <realm>Shared</realm> <file line="14-L18">lua/includes/extensions/net.lua</file> <args> <arg name="messageName" type="string">The message name to hook to.</arg> <arg name="callback" type="function">The function to be called if the specified message was received. <callback> <arg type="number" name="len">Length of the message, in bits.</arg> <arg type="Player" name="ply">The player that sent the message, works **only** server-side.</arg> </callback>⤶ </callback></arg>⤶ </args> </function> <example> <description>An example with receiving message clientside, when sent from the server.</description> <code> if ( SERVER ) then util.AddNetworkString( "message_to_clients" ) concommand.Add( "send_message", function( ply, cmd, args ) net.Start( "message_to_clients" ) net.WriteString( args[ 1 ] or "my very cool message, yeah!" ) net.WriteUInt( 1337, 16 ) net.Broadcast() end ) else net.Receive( "message_to_clients", function( len, ply ) print( "Message from server received.
