The '''IS_SMALL''' packet is a general purpose packet comprised of 8 bytes. The packet is designed to prevent repeating a common structure which would be the same for many packets. Unlike the [[IS_TINY]] the IS_SMALL also contains the UVal, a 4 byte unsigned integer.

=== Size ===

The size of the packet, always 8 bytes.

=== Type ===

The packet type from the [[InSim_enumerations#ISP|ISP_]] enumeration, always ISP_SMALL.

=== ReqI ===

ReqI must be set to non-zero when sending a request for information to LFS, and in turn the replying packet will contain the same value set in its ReqI. For packets sent by LFS without a request, ReqI is zero.

=== SubT ===

The packet's sub-type, which is a value from the [[InSim_enumerations#SMALL|SMALL_]] enum.

* SMALL_NONE: Not used
* SMALL_SSP: Request to start sending OutSim packets at the specified interval
* SMALL_SSG: Request to start sending OutGauge packets at the specified interval
* SMALL_VTA: Send to set the current vote action, from the VOTE_ enumeration
* SMALL_TMS: Send in single-player mode to stop time, 1 means to stop and 0 to carry on. This freezes the game but is not the same as pausing, as the game must be unfrozen before any further actions can be undertaken
* SMALL_STP: Send when frozen to update the game time by the specified hundredths
* SMALL_RTP: Sent in response to an [[IS_TINY]] with a SubT of TINY_GTH. Contains the time in ms.
* SMALL_NLI: Send to set the [[IS_NLP]]/[[IS_MCI]] interval
* SMALL_ALC: Send to set allowed cars; sent in reply to [[IS_TINY]] TINY_ALC.
* SMALL_LCS: Send to set the local car's switches; sent in reply to [[IS_TINY]] TINY_LCS.
* SMALL_LCL: Send to set the local car's lights; sent in reply to [[IS_TINY]] TINY_LCL.
* SMALL_AII: Send to request a local AI car's info.

Note: SMALL_TMS and SMALL_STP are currently not available in LFS 0.8B/InSim 10.

=== UVal ===

A general purpose 4-byte unsigned integer, the meaning of which varies depending on [[#SubT|SubT]].
