<function name="WriteInt" parent="net" type="libraryfunc"> <description> Appends an integer - a whole number - to the current net message. Can be read back with <page>net.ReadInt</page> on the receiving end. Use <page>net.WriteUInt</page> to send an unsigned number (that you know will never be negative).
