<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. Appends a signed integer - a whole number, positive/negative - 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). Use <page>net.WriteFloat</page> for a non-whole number (e.g. `2.25`). </description> <realm>Shared</realm> <args> <arg name="integer" type="number">The integer to be sent.</arg> <arg name="bitCount" type="number">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`.
