<function name="WriteUInt" parent="net" type="libraryfunc"> <description>Appends an unsigned integer with the specified number of bits to the current net message. Use <page>net.WriteInt</page> if you want to send negative and positive numbers. Use <page>net.WriteFloat</page> for a non-whole number (e.g. `2.25`). <note>Unsigned numbers **do not** support negative numbers.</note> </description> <realm>Shared</realm> <args> <arg name="unsignedInteger" type="number">The unsigned integer to be sent.</arg> <arg name="bitCount" type="number">The size of the integer to be sent, in bits. Acceptable values range from any number `1` to `32` inclusive. For reference: `1` = bit, `4` = nibble, `8` = byte, `16` = short, `32` = long. Consult the table below to determine the bit count you need. The minimum value for all bit counts is `0`. | Bit Count | Maximum value | |-----------|:--------------:| | 1 | 1 | | 2 | 3 | | 3 | 7 | | 4 | 15 | | 5 | 31 | | 6 | 63 | | 7 | 127 | | 8 | 255 | | 9 | 511 | | 10 | 1023 | | 11 | 2047 | | 12 | 4095 | | 13 | 8191 | | 14 | 16383 | | 15 | 32767 | | 16 | 65535 | | 17 | 131071 | | 18 | 262143 | | 19 | 524287 | | 20 | 1048575 | | 21 | 2097151 | | 22 | 4194303 | | 23 | 8388607 | | 24 | 16777215 | | 25 | 33554431 | | 26 | 67108863 | | 27 | 134217727 | | 28 | 268435455 | | 29 | 536870911 | | 30 | 1073741823 | | 31 | 2147483647 | | 32 | 4294967295 | </arg> </args> </function> <example> <description>Sends the server the client's age.</description> <code> -- Client⤶ net.Start( "SendAge" ) net.WriteUInt( 3, 2 ) -- Only 2 bits are needed to store the number "3". net.SendToServer() ⤶ -- Server⤶ util.AddNetworkString( "SendAge" )⤶ ⤶ net.Receive( "SendAge", function( len, ply ) local age = net.ReadUInt( 2 ) -- use the same number of bits that were written. ⤶ print("Player " .. ply:Nick() ..
